1. Introduction
AVPro Video is the newest video playback plugin from RenderHeads. We previously
developed the AVPro QuickTime and AVPro Windows Media plugins for Unity. In this next
generation of plugins we aim to create an easy to use, cross-platform video playback system
that uses the native features of each platform.

1.2 Trial Version
We offer an unlimited trial version of AVPro Video for download from our website at
http://renderheads.com/product/avpro-video/​. The trial version has no missing features or
time restrictions but it does apply a watermark to the rendered output. The watermarking
does have a small performance impact which is only really noticeable on very high resolution
videos.

3. Installation
1. Open up a ​fresh​ Unity session (to clear any locked plugin files)
2. Import the ​unitypackage ​file into your Unity project. If prompted to upgrade some
scripts click Yes.

3.1 Trial Version & Watermark Notes
3.1.1 Watermark
If you are using a trial version of the plugin then you will see a watermark displayed over the
video. The watermark is in the form of a “RenderHeads” logo that animates around the
screen, or a thick horizontal bar that move around the screen. In Windows if the GPU
decoding path is used when the watermark isn’t displayed - instead every few seconds the
video size will scale down.
The full version of AVPro Video has no watermarks for any platforms. If you use one of the
platform specific packages (eg AVPro Video for iOS, or AVPro Video for Windows) then you
will not see the watermark on the platform you purchased for, but you will see the watermark
on the other platforms. For example if you purchased AVPro Video for iOS then you will still
see the watermark in the Unity editor as this is running on Windows/OS X, but the videos
played back when you deploy to your iOS device will be watermark-free.

3.1.2 Updating from Trial Version

If you are upgrading from the trial version, make sure you delete the old /Assets/Plugins
folder as this contains the trial plugin and could conflict. You may need to close Unity first,
delete the files manually and then restart Unity and re-import the package (because Unity
locks native plugin files once they are loaded).
You can check which version you have installed by adding an MediaPlayer component to
your scene and clicking on the ‘about’ button in the Inspector for that component. The
version number is displayed in this box.

3.2 Installing Multiple Platform Packages
If you are not using the full all-in-one AVPro Video package and instead have opted to
purchase multiple individual platform packages then the installation must be done carefully,

5 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

especially when upgrading to a new version.
If you have installed the iOS package then it will also contain plugins for all of the other
platforms but with the watermark enabled. This means that if you then try to install another
AVPro Video package it may not override the plugins correctly. Here is how to resolve this
using the iOS and Android package as examples:
1. Open a fresh Unity instance (this is important as otherwise Unity may have locked
the plugin files which prevents them from being upgraded)
2. Import the iOS package
3. Import the Android package, but make sure that you have the iOS native plugin file
unticked (so that it is not overwritten)
A similar process can be applied for other package combinations.

4.1.1 Android
●
●
●
●
●

This plugin requires an API level minimum of 15
Under the hood we’re using the Android MediaPlayer API
If you want to support streaming don’t forget to set the “Internet Access” option in
Player Settings to “require”
For rendering we supports OpenGL ES 2.0 and OpenGL ES 3.0
Multi-threaded rendering is supported

4.1.2 iOS / tvOS
●

●
●

●
●

iOS and tvOS support requires Unity 5.4 or above (due to a breaking change in the
Unity API). If you require Unity 5.3 or below support for iOS then please contact us.
Otherwise you will have to upgrade to 5.4 or above.
Under the hood we’re using the AVFoundation API
If you want to support streaming you need to enable HTTP downloads explicitly. For
iOS this is an option in newer versions of Unity, but for Mac OS X and older versions
of Unity you have to do this explicitly by editing the plist file. There are notes below
on how to do this.
For rendering we support OpenGL ES 2.0, OpenGL ES 3.0 and Metal
Multi-threaded rendering is supported

4.1.3 Mac OS X

7 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

●
●
●

●
●

Only 64-bit (x86_64) builds are supported (Apple dropped 32-bit support back in
2012 when launching OS X 10.8).
Under the hood we’re using the AVFoundation API
If you want to support streaming you need to enable HTTP downloads explicitly. For
iOS this is an option in newer versions of Unity, but for Mac OS X and older versions
of Unity you have to do this explicitly by editing the plist file. There are notes below
on how to do this.
For rendering on Mac OS X we support OpenGL Legacy and OpenGL Core and
Metal.
Multi-threaded rendering is supported

4.1.4 Windows
●

●
●

Under the hood we’re using the Media Foundation and DirectShow API’s. Media
Foundation is used for Windows 8 and above while DirectShow is used as a fallback
for Windows 7 and below.
For rendering we support Direct3D 9, Direct3D 11 and OpenGL Legacy.
Multi-threaded rendering is supported.

4.1.5 Windows Store / UWP / Hololens
●

For streaming video don’t forget to enable to “InternetClient” capability option in
Unity’s Player Settings.

4.1.6 WebGL
●
●

●

The supported formats and features is dependant on the web browser capabilities.
We have tested successfully with the following browsers
○ macOS
■ Safari 9.1
○ Windows
■ Microsoft Edge 38.14393.0.0
■ Mozilla Firefox 51.0
■ Google Chrome 56.0
The following browsers are not supported:
○ Internet Explorer 11 (any version), instead use the Microsoft Edge browser

4.2 Video File Location
Video files can be played in almost any location, however we recommend placing video files
in the​ /Assets/StreamingAssets/​ folder in your Unity project as this is the easiest folder to

8 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

get started with. StreamingAssets is a special folder that Unity copies to the build without
processing. Files copied elsewhere will require manual copying to the build location.
The MediaPlayer component allows you to browse for video files and specify them relative to
a parent folder:

The Video Location field specifies the master location of the video file while the Video Path
field specifies where to locate the file relative to the Location.
For example if your file is stored in “Assets/StreamingAssets/video.mp4” you would set the
Location to “Relative To Streaming Assets Folder” and set the Video Path to “video.mp4”.
Sub-folders are also supported so a video located at
“Assets/StreamingAssets/myfolder/video.mp4” would have it’s Video Path set to
“myfolder/video.mp4”.
You can also specify absolute paths, URLs or paths relative to other locations:
4.2.1 Relative To StreamingAssets Folder
This is the best and most common location for video files. This folder is located at
“Assets/StreamingAssets/” and you must create it if it doesn’t exist. Files copied to this
folder will not be imported or processed by Unity but they will be copied with the build
automatically.
4.2.2 Absolute Path or URL
Here you can specify a full URL or absolute path to the video file. A URL could be in the
form “http://myserver.com/myvideo.mp4” or “rtsp://myserver.com:8080/mystream.rtsp”
depending on the platform support and streaming service used.
An absolute path would look like:
●

C:/MyFolder/AnotherFolder/MyVideo.mp4 (Windows)
9 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

●
●
●

/Users/Mike/downloads/MyVideo.mp4 (Mac/Linux)
/Storage/SD/Videos/MyVideo.mp4 (Android external SDCARD)
/Storage/emulated/0/MyFolder/MyVideo.mp4 (Android local file system)

Using absolute paths can be useful for testing but isn’t useful when deploying to other
machines that don’t necessarily have the same file structure.
4.2.3 Relative To Project Folder
The project folder is the folder of your Unity project, so the folder containing the Assets,
Library and Project Settings sub-folders. Specifying files relative to the project folder can be
useful when you don’t want to include the video files in your Unity Assets folder but want to
keep them within the project folder structure. Often making a sub-folder called “Videos” is
useful. One possible problem of using this location is that when making a build your video
files will not be copied automatically to the build destination so they require manual copying.
For builds this folder should be located:
●
●
●
●

Windows - at the same level as your EXE
Mac - at the same level as the Contents folder in your app bundle
iOS - at the same level as the AppName.app/Data folder
Android - not accessible due to APK packaging unless you build the APK manually.

4.2.4 Relative To Data Folder
The data folder is specified by Unity here:
http://docs.unity3d.com/ScriptReference/Application-dataPath.html
It isn’t that useful to put video files into this folder directly as they would then be processed
by Unity into MovieTexture’s and will bloat your project size. If you want to stop Unity
processing the video files simply rename the extension to something Unity doesn’t
understand, so “myvideo.mp4” could be renamed to “myvideo.mp4.bin”. Files within the
data folder (Assets folder in the editor) are not copied automatically to builds so you would
have to manually copy them.

4.2.5 Relative to Persistent Data Folder
The persistent data folder is specified by Unity here:
http://docs.unity3d.com/ScriptReference/Application-persistentDataPath.html
For UWP platforms this would resolve to “ms-appdata:///local/”

When encoding MP4 videos for streaming make sure they are encoded with the video
header data at the beginning of the file. You normally do this by selecting “Fast Start” in
QuickTime encoder, or use the “-movflags faststart” in FFMPEG, Other encoders will have a
similar option. To prepare an MP4 for streaming using FFMPEG you can use the following
command:
ffmpeg -i %1 -acodec copy -vcodec copy -movflags faststart %1-streaming.mp4

12 / 77

Vimeo Note:
If you are streaming videos from VIMEO as MP4 then you should note that you can replace
the “.mp4” part in the URL with “.m3u8” to instead make it an HLS stream. This may be
particularly useful if you are developing apps for the Apple’s App Store as you would need to
use HLS streaming to pass certification (as for April 2016).

4.3.1 OS X, iOS and tvOS Streaming
This platform supports streaming of HLS streams which typically end with the m3u or m3u8
extension.
If you have an HTTPS URL it should work fine because Apple trusts the secure connection.
If you can only use HTTP then you app has to have a special flag set to let it use HTTP
connections (this is a security issue for Apple).
This setting is exposed in the Unity Player Settings here for iOS and tvOS:

The setting is also exposed in the scripting API here:
http://docs.unity3d.com/ScriptReference/PlayerSettings.iOS-allowHTTPDownload.html
If for some reason your version of Unity doesn’t expose this then you will have to add it
manually. In the Unity editor you need to edit "Unity.app/Contents/Info.plist" and in your built
application you would need to edit "your.app/Contents/Info.plist". These files need to have
these keys added:
NSAppTransportSecurity

NSAllowsArbitraryLoads


You can find more information about this here:
http://ste.vn/2015/06/10/configuring-app-transport-security-ios-9-osx-10-11/
We’ve also included a post process build script called “PostProcessBuild.cs” in the project
which edits the plist and adds this attribute. Currently it’s only set for iOS but you can edit
the #define at the top to allow Mac OS X too.
4.3.2 Android Streaming

“Require”:

4.4 Augmented / Virtual Reality Notes
So far we have tested AVPro Video with:
● Gear VR
● Google Cardboard
● Google Daydream (currently in beta, we’ve seen some performance issues)
● Oculus Rift
● HTC Vive
● Microsoft Hololens
VR is still very new and you should always check for the latest recommended installation
steps when creating your project. We found a lot of out of date setup instructions on the
net.
AVPro Video supports 4K MP4 playback for creating 360 degree experiences. Stereo 4K
videos in both top-bottom and side-by-side formats are also supported. If you’re using
Windows 10 and have an Nvidia Geforce 1000 series (eg 1070) you can display 8K H.265
videos!
See the FAQ for tips to achieve high resolution video playback for VR.
For software decoders reducing the complexity of the encoded video will give the decoding
engine a much easier time and could result in higher frames rates and lower CPU/GPU
usage. Possible encoding tweaks include:
●
●
●
●
●

Use the lowest profile level possible
Don’t use too many reference frames
Don’t use too many b-frames
Disable CABAC
Use the slices option (eg -slices 4)

4.4.1 Stereo VR
AVPro Video supports stereoscopic videos in the top-bottom and left-right formats. You can
set the stereo packing format of your video in the Media Properties panel:

15 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

Now when using the InsideSphere shader on a mesh it will automatically map the right part
of the video to each eye. See the “Demo_360SphereVideo” scene for an example of how
this works.
Optionally you can manually set the material properties. The included shader
“InsideSphere.shader” allows you to easily set what format your video is in via a drop-down
in the material:

Select “Stereo Debug Tinting” to colour the left and right eyes different colours so you can be
sure the stereo is working.
NOTE​: Be sure to add the "UpdateStereoMaterial” component script to your scene when
using this material and a stereo video. Often stereo VR requires 2 cameras, each set to a
different layer mask and 2 spheres also set to a different mask. AVPro Video doesn’t require
this and just uses your normal single camera and single sphere.

4.4.2 VR Audio

16 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

Currently only the Windows plugin has support for audio manipulation in VR.
There are two main audio issues with VR in Unity:
1. Audio redirection
Some VR systems such as the Oculus Rift and HTC Vive have their own audio
output device and one needs to redirect audio to these devices instead of the system
default audio device. Unity does this automatically for its internal audio, but AVPro
Video renders to the system default audio device.
This issue can be solved by either using the AudioOutput component (see below).
This component redirects the audio to be rendered by Unity and so it goes to the
correct device. AudioOutput requires that the Media Foundation video API be used,
so if you need to use the DirectShow API you can specify the name of the output
device manually in the field “Force Audio Output Device”:

The device name to use can be retrieved from the VR API or hard coded. For
Oculus Rift the name is usually “Rift Audio” and for HTC Vive it is “HTC VIVE USB
Audio”.
2. Audio spatialisation
Audio needs to rotate as the user moves their head in the virtual world. This can be
achieve by using the AudioOutput component which redirects the audio from the
video into Unity (via Unity’s AudioListener).

This component should be stacked above its required AudioSource component.
AudioOutput requires that the video API is set to Media Foundation and that the “Use
17 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

Unity Audio” tickbox is selected.

For proper 3D audio placement you will also need to add a spatialiser plugin to the
Unity Audio Settings screen (in Unity 5.4 and above) and tick the “spatialize” tickbox
on the Audio Source.

4.4.3 Android OES playback path
For Android there is a special playback option called “Use Fast OES Path”. This option
caters especially for VR where users are trying to get the highest possible frame rate and
resolution out of the device (without it overheating at the same time). The option is
available in the Platform Specific section of the MediaPlayer component:

The OES path is not enabled by default because it requires some special care to be taken
and can be tricky for beginners. When this option is enabled the Android GPU returns
special OES textures (see EGL extension OES_EGL_image_external) that are hardware
specific. Unfortunately Unity isn’t able to use these textures directly, so you can’t just map
them to a material or UI. To use the texture a GLSL shader must be used. Unfortunately
Unity’s GLSL support isn’t as good as its CG shader support so again this makes things
more tricky. The GLSL compiler only happens on the device (not inside Unity) so errors in
18 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

the shader can be difficult to debug.
We have included a version of the VR sphere shader that supports stereo videos as an
example. Hopefully in the future we can improve the integration of these shaders so they
aren’t such special cases. This playback path is much faster though, so is definitely worth
exploring.
For the sphere demo scene, simply change the shader on the sphere mesh material to be
one of the “VR” “OES” ones and tick the “Use Fast OES Path” on the MediaPlayer
component.

4.5 Hap Codec Notes
The Hap video codec is natively supported by AVPro Video on certain platforms and has the
following benefits:
● Very low CPU usage
● GPU decompression
● Low memory usage
● Supports very high resolutions
● Supports alpha channel transparency
The main down side is:
● Very large files
AVI and MOV containers can both be used however we recommend the MOV container.
Hap is only supported on Windows and Mac OS X platforms.
4.5.1 Windows Support
Hap, Hap Alpha, HapQ and HapQ Alpha are supported. Hap currently requires the
“DirectShow” video API to be selected:

19 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

4.5.2 Mac OS X Support
Hap, Hap Alpha, HapQ and HapQ Alpha are supported.

4.5.3 Encoding
You can download the QuickTime codec for Windows and macOS here:
https://github.com/Vidvox/hap-qt-codec/releases
This codec can be used with QuickTime Pro or any other software that supports QuickTime
codecs such as Adobe After Effects and Adobe Premiere.
Alternatively you can use a recent build of FFMPEG with the following command-lines:
●
●
●

ffmpeg -i input.mov -vcodec hap -format hap output-hap.mov
ffmpeg -i input.mov -vcodec hap -format hap_alpha output-hap.mov
ffmpeg -i input.mov -vcodec hap -format hap_q output-hap.mov

Notes:
● Width and height must be multiple of a 4.
● Hap Alpha requires straight not pre-multipled alpha.
● The default ffmpeg doesn’t include the Snappy library (due to licensing we assume)
that Hap uses for compression - thus ffmpeg generated Hap files are often quite
large. You would need to build ffmpeg yourself with Snappy enabled, or use the
QuickTime encoder.
● You can also add the “-chunks 4” option which will encode each frame into 4 chunks
so the decoding work can be split across multiple threads, resulting in faster
decoding as long as the disk can keep up.
● Sadly ffmpeg doesn’t yet support the HapQ Alpha format.

4.6 Transparency Notes
Not many video codecs have native support for transparency / alpha channels. Formats
supported by some platforms of AVPro Video are:
●

Uncompressed YUVA
○ Uncompressed isn’t ideal for file size or disk bandwidth but can still be used
as a fallback
ProRes 4444
○ Best support is on Mac OS X. Files are huge.

○ Legacy format. We support it only via 3rd party DirectShow plugins for
Windows (eg LAV Filters)

4.6.1 Alpha Packing
Alternatively you can encode your videos in video formats that don’t support an alpha
channel by packing the alpha channel into the same frame. You can double the width for a
left-right packing layout, or double the height for a top-bottom packing layout. This packing
could be created in software such as AfterEffects, or the command-line ffmpeg tool can be
used. The packing format is set in the “Media Properties” panel of the AVPro Video
MediaPlayer component:

Here we show two examples using ffmpeg to convert to an alpha packed format:
Left-right alpha packing:
ffmpeg -i %1 -vf "split [a], pad=iw*2:ih [b], [a] alphaextract, [b] overlay=w" -y %1.mp4

Top-bottom alpha packing:
ffmpeg -i %1 -vf "split [a], pad=iw:ih*2 [b], [a] alphaextract, [b] overlay=0:h" -y %1-tb.mp4

4.7 Hardware Decoding
AVPro Video supports hardware decoding on most platforms for optimal performance.
WebGL, Windows 8.1, Windows 10, macOS, tvOS, iOS and Android all default to hardware
decoding when possible. When playing back multiple videos simultaneously one must be
careful not to exceed the number of videos that the hardware can play back smoothly. We
have tried to collect information about the limits of specific hardware.
4.7.1 NVidia
NVidia GPU’s use a technology called “Purevideo” or “NVDec” to off-load decoding from the
CPU. More information can be found here:

4.7.3 Intel
Intel’s Quick Sync technology is a dedicated video decoder hardware built into the CPU.
Intel Kaby Lake supports H.265 10-bit decoding!

4.8 Multi-GPU SLI / CrossFire Notes
Multiple GPU’s are often used to accelerate high-end rendering but it brings with it some
subtle challenges for video playback. Here we write some notes about our experience using
Nvidia SLI on Windows (specifically Windows 8.1 with dual Nvidia M6000 cards).
Using Alternate Frame Rendering SLI (AFR SLI) can cause stuttering when using the Media
Foundation hardware decoding because only one GPU is doing the decoding and then it
must pass the frames back to the other GPU which is a slow operation and defeats the
purpose of SLI. One option here is to disable GPU decoding in AVPro Video, which is fine
for lower resolution videos, but often the CPU just isn’t fast enough for very high resolution
content. AFR can also suffer from so called “micro stutters” caused by each GPU handling
the flip presentation independently which isn’t ideal for video playback on large video walls.
Another option is to use the cards in “SLI VR” mode … To be continued..

4.9 Subtitle Notes
AVPro Video supports external subtitles in the SRT format. Subtitles internal to media files
are not yet supported. See the subtitle demo scene to see how to use subtitles.

4.10 DRM Notes
DRM support is currently not a key feature of AVPro Video, but we aim to improve support in
the future. DRM that we know works with the plugin includes:
●

Android
○ HLS with AES-128 (make sure your TS segments are 188 bytes aligned for
maximum Android compatibility)

5. Quick Start Examples
5.1 Quick Start: Fastest Start for Unity Experts
1. Put video files in the StreamingAssets folder
2. Use the MediaPlayer script to play your video (set Video Path to the file name of your
video file).
3. Use one of the display scripts to display your video (eg DisplayIMGUI, DisplayUGUI,
ApplytoMaterial)

5.2 Quick Start: Fullscreen Video Player using Prefabs
AVPro Video includes a number of example prefabs you can use to easily add video
playback to your project. The following steps will create an application that plays back a
fullscreen video:
1. Create a new Unity project
2. Import the AVProVideo package
3. From the AVPro/Prefabs folder in the Project window, drag the FullscreenVideo
prefab to your Hierarchy window

26 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

4. Create a folder called StreamingAssets in your Project window and copy your video
file (say MP4 file) into that folder
5. Enter the file name (including extension) into the Video Path field in the MediaPlayer
component (eg myvideo.mp4)
6. Build and deploy your application, the video will be displayed fullscreen
The DisplayIMGUI component script is just one of the components for displaying video. It
uses the legacy Unity IMGUI system which always renders on top of everything else. Try
using the DisplayBackground or DisplayUGUI components for more control if you don’t want
your video to be on top.

5.3 Quick Start: 3D Mesh Video Player using Components
AVPro Video includes a number of easy to use script components you can add to your
scene. In this example we show how to use the components to play a video onto a material
which is applied to a 3D model in the scene.
1. Create a new Unity project
2. Import the AVProVideo package
3. Create a new GameObject from the “GameObject > AVPro Video > Media Player”
menu command
4. Click the “Add Component” button and add “AVPro Video > Apply To Mesh”
5. Drag the Media Player script to the “Media” field in the Apply To Mesh script, this tells
the Apply to Mesh script which media player to use
6. Create a sphere via the “GameObject > 3D Object > Sphere” menu command
7. Drag the Mesh Renderer component to the “Mesh” field in the Apply To Mesh script,
this tells the Apply to Mesh script which mesh to use

27 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

8. Create a folder called StreamingAssets in your Project window and copy your video
file (say MP4 file) into that folder
9. Enter the file name (including extension) into the Video Path field in the MediaPlayer
component (eg myvideo.mp4)
10. Build and deploy your application, the video will be displayed on your 3D sphere

28 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

6. Usage
6.1 Getting Started
The easiest way to get started is to look at the included demos and see what script
components have been used. For video playback you need 3 things in your scene:
1. The video file to play:
Create a “StreamingAssets” folder in your Project window
Copy your video file (usually MP4 file, but consult the list of supported formats for
your platform below) to the StreamingAssets folder
2. A MediaPlayer script to load and play the video:
Create a GameObject and add the MediaPlayer script to it
Set the Video Path field to the name of your video file (e.g. myvideo.mp4)
3. A script to display the video:
Decide how and where you want your video file to appear. There are a number of
different display component scripts included for different usage scenarios. If you
want to display the video on top of everything in your scene just add the
DisplayIMGUI script to a GameObject in your scene and set the Media Player field
your MediaPlayer component. Other display components work similarly.

6.2 Unsupported Platform Fallback
AVPro Video is designed to still function even on platforms that aren’t natively supported.
Instead of displaying the actual video though, a dummy 10 second long “AVPro” visual is
shown. All of the video controls should still work. For example if you are running your editor
in Linux the dummy video player will appear in the editor and the real video will appear when
you deploy to supported platforms. If you deploy to an unsupported platform such as
Samsung TV you will also see the dummy video player. The code is easily extendable to
add custom video players for any unsupported platform.

6.3. Components
Included are a number of components to make this asset easy to use. The components are
located in the AVProVideo/Scripts/Components folder or you can add them from the
Components menu:

6.4 Scripting

6.4.1 Namespace
All scripts use the namespace RenderHeads.Media.AVProVideo so be sure to add “using
RenderHeads.Media.AVProVideo” to the top of your source files.

6.4.2 Media Player Scripting
Most scripting is likely to center around the MediaPlayer.cs script. This script handles the
loading, playback and updating of videos. The script exposes a number of interfaces related
to different use cases and can be found in Interfaces.cs
MediaPlayer exposes 3 main interfaces:
● Info Interface
○ The IMediaInfo interface is exposed by the Info property
○ This interface is used to access information about the media, eg:
MediaPlayer mp;
mp.Info.GetVideoWidth();

●

Control Interface
○ The IMediaControl interface is exposed by the Control property
○ This interface is used to control playback, eg:
MediaPlayer mp;
mp.Control.Pause();

●

TextureProducer interface
○ The IMediaProducer interface is exposed by the TextureProducer property
○ This interface is used to get information about how to display the current
texture and is used by the Display components, eg:
MediaPlayer mp;
Texture videoTexture = mp.TextureProducer.GetTexture();

The MediaPlayer script also has a number of methods for controlling loading of media:
●

●

OpenVideoFromFile()
○ Loads the video specified. Useful if you need manual control over when the
video is loaded
CloseVideo()
○ Closes the video, freeing memory

36 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

6.4.3 Events
MediaPlayer currently has these events:
●
●
●
●
●
●
●
●
●
●

MetaDataReady - Called when the width, height, duration etc data is available
ReadyToPlay - Called when the video is loaded and ready to play
Started - Called when the playback starts
FirstFrameReady - Called when the first frame has been rendered
FinishedPlaying - Called when a non-looping video has finished playing
Closing - Called when the the media is closing
Error - Called when an error occurred, usually during loading
SubtitleChanged - Called when the subtitles change
Stalled - Called when media is stalled (eg. when lost connection to media stream)
Unstalled - Called when media is resumed form a stalled state (eg. when lost
connection is re-established)

Scripting example:
// Add the event listener (can also do this via the editor GUI)
MediaPlayer mp;
mp.Events.AddListener(OnVideoEvent);
// Callback function to handle events
public void OnVideoEvent(MediaPlayer mp, MediaPlayerEvent.EventType et,
ErrorCode errorCode)
{
switch (et)
{
case MediaPlayerEvent.EventType.ReadyToPlay:
mp.Control.Play();
break;
case MediaPlayerEvent.EventType.FirstFrameReady:
Debug.Log("First frame ready");
break;
case MediaPlayerEvent.EventType.FinishedPlaying:
mp.Control.Rewind();
break;
}
Debug.Log("Event: " + et.ToString());
}

8. Scripting Reference
AVPro Video is designed to be used mainly with the supplied drag and drop component but
there are always times when a bit of scripting is needed. The asset includes sample scenes
which give some examples of how to use scripting to control video playback, apply video
textures to materials etc which are useful to learn from. The full class reference is available
online here:
http://downloads.renderheads.com/docs/AVProVideoClassReference/
In this document we have included a simplified version of the highlights.

MediaPlayer class
The MediaPlayer class is the main class for video playback and is where video files are
specified and controlled. This class is mainly controlled via the Unity Inspector UI and for
scripting through the interface properties it exposes.

* Yes, only in Windows 10 and only 4:2:0. If you use DirectShow and 3rd party filter
then 4:4:4 can be supported. Using Media Foundation no audio codecs (Vorbis or
Opus) are supported and will cause the video to fail to load if included.
** Apparently Apple will release support soon
*** Requires option “Force DirectShow” to be ticked
**** Older versions of Windows (Vista and XP) do not have support for H.264
decoding
***** iOS seems to often have trouble with MP3 audio tracks in a video file, so best to
use AAC instead

Cells with “?” are one’s we’re not sure about. We will do more testing and continue to
update this table. For more details on which codecs and what type of encoding is best, see
the per-platform details below.

9.1 Android
Android supports many media formats. For a complete list check the Android documentation
here: ​https://developer.android.com/guide/appendix/media-formats.html
HEVC (H.265) support was officially added in Android 5.0 (Lollipop) but only as a software
decoding implementation on older devices.
We have found that using GearVR on Samsung Galaxy S6 and S7 that H.265 codec works
best, with a resolution of 3840x1920 at 30fps, or 2048x2048 at 60fps.

decoding: ​http://kodi.wiki/view/Android_hardware

9.2 iOS, tvOS and OS X
9.2.1 iOS
Many media formats are supported on iOS including H.264. For a complete list check the
iOS documentation here:
https://developer.apple.com/library/ios/documentation/Miscellaneous/Conceptual/iPhoneOS
TechOverview/MediaLayer/MediaLayer.html
The iPhone5C is a low-powered mobile device and has a limitation that the videos must be
less than 2 megapixels in resolution.
iOS seems to often have trouble with MP3 audio tracks in a video file, so best to use AAC
instead.
iOS also seems to allocate a LOT of SYSTEM memory when loading videos. Unfortunately
we’re not able to control this which means you have to be very careful when trying to load
large or multiple videos, especially with the 1GB iOS devices. We recommend only using a
single MediaPlayer instance and reusing it for all video loads. The memory issue may be
helped by encoding your videos with less reference frames but we haven’t tested this for
sure.
9.2.2 macOS / OS X
Many media formats are supported on iOS including H.264.
In OS X, ProRes 422 and ProRes 4444 are also supported.
OS X Yosemite and above, supports the following additional formats:
●

9.5 WebGL
Support for WebGL platform is still varied and depends on the platform and browser support.
Some formats such as AVI file container are not supported at all. As with all other platforms,
H.264 video in an MP4 container is the most widely supported format.
Adaptive streaming (such as HLS) is still not supported natively by most browsers, but we
have seen it working in the Microsoft Edge and Safari browsers.

Appendix A - Frequently Asked Questions
1. Why won’t my high-resolution video file play on Windows?
The ability to play high resolution videos depends on the version of Windows
operating system and which video codecs you have installed.
By default AVPro Video will try to use the standard Microsoft codecs that come with
Windows. These have limitations, for example:
Decoder

Windows 7 and
below

Windows 8+

h.264

1080p

2160p (4K)

If you want to use 3rd party codecs you can install them to improve the range of
resolution and format options available. These come in the form of Media
Foundation or DirectShow codecs.
The LAV Filters are a great example of
DirectShow codecs that will allow for higher resolution video decoding.
2. Does Time.timeScale affect video playback speed?
Yes we have BETA support for time.timeScale and time.captureFramerate. Simply
enable the option on the Media Player component in the panel labelled “Global
Settings”.
3. Does AVPro Video support playing YouTube videos or live streams?
Yes and no. If you enter a YouTube URL into AVPro Video it will not be able to play
it because this is the URL to the website and not the video. It is possible to gain
access to the underlying MP4 file or HLS stream URL which will work with AVPro
Video. This may be against the terms and conditions of YouTube though.
4. How can I get smoother video playback for my Windows VR app?
This is usually caused by the video decoding taking too much CPU time. Some
videos (especially highly compressed ones) require a lot of CPU time to decode each
frame.
Try enabling the hardware decoding option in “Platform Specific” panel. This will
enable your application to use GPU decoding which is much faster. This option is
only supported on Windows 8.1 and above and when D3D11 graphics API is used.
You could also try re-encoding your video using settings that are less demanding for
53 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

the decoder. Most H.264 encoders have a ‘fast decode’ preset, or you can manually
change settings such as disabling CABAC, reducing the number of reference frames,
reducing bitrate, disabling B-frames, disabling the loop (deblocking) filter etc.
You could also try switching to another video codec that allows for less CPU
intensive decoding. Codecs such as H.264 / H.265 are generally very heavy on the
CPU. Hap is an extremely fast codec but will result in large files.

5. Is GPU hardware decoding available?
Yes it is on most platforms. Android, iOS, tvOS and macOS mostly use GPU
decoding - but it depends on the codec. For Windows GPU decoding is enabled by
default but is only available for Windows 8.1 and above and when using D3D11
graphics API. You can toggle GPU decoding is enabled via the Platform Specific
panel:

6. Is multi-channel audio supported?
Audio with more than 2 channels should be supported on desktop platforms. On
Windows you will need to set your sound settings in the Control Panel for the number
of channels you want to output. If you leave your Windows sound settings as stereo
then the audio will get mixed to stereo.
7. Why isn’t seeking accurate / responsive?
The way seeking works depends on the platform. Some platforms support frame
accurate seeking but most will only seek to the nearest key-frame in the video. In
general to improve seek accuracy and responsiveness you can re-encode your
videos with more frequent key-frames (smaller GOP). The downside of this is that
the size of the video file will increase (more key-frames = larger file). We have two
seek functions: Seek() and SeekFast(). SeekFast can be used when accuracy isn’t
important but whether it’s faster or not depends on support from the platform and can
54 / 77

vary based on the video codec used.
8. Windows - Why isn’t my stereo top-bottom or left-right video displaying
correctly?
If your stereo video is only decoding one of the views then this is because there is
stereo metadata encoded within the video which causes our Media Foundation
decoder to interpret incorrectly. The only way to currently solve this is to remove the
metadata from the video. One way to do this is using FFMPEG:
ffmpeg -i %1 %1-video.nut
ffmpeg -i %1-video.nut -crf 20 %1-stripped.mp4
9. Windows - Why do videos take a long time (1-2 seconds) to open when using
DirectShow?

We have seen this happen when the Nvidia Geforce Experience is installed and the
Share option is enabled. Disabling the share option or uninstalling this software
resolves this issue.
10. Hap Codec - Why don’t my Hap encoded videos play?
If your platform is Windows desktop then this is usually because the DirectShow
video API has not been selected. See the notes above about how to use the Hap
codec.
11. macOS - Publishing for Mac App Store and get error “Invalid Signature”?
We’re not sure why this happens but we’ve had reports that simply deleting all of the
.meta files inside the AVProVideo.bundle will resolve this issue.
12. iOS - Why doesn’t my video file play properly?
Make sure that your video file doesn’t contain an MP3 audio track. In our experience
iOS doesn’t handle MP3 audio correctly and can often lead to the whole file not
loading/playing correctly. Use AAC for audio instead.
13. iOS - Can I playback a video from the Videos library?
55 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

Yes if the video is not content protected and you have it's URL. URL's for items in
the video library take the following form:
ipod-library://item/item.m4v?id=1234567890123456789
You can get the URL of an item by using the MPMediaQuery class from the
MediaPlayer framework.
14. iOS - Can I playback a video from the Photo Library?
Yes. You need to use the UIImagePickerController to select the video. This will
result in the video being processed into your app's temp folder where you can access
it via the URL returned from the controller.
15. iOS - How can I fix the error message: "Missing Push Notification Entitlement Your app includes an API for Apple's Push Notification service, but the
aps-environment entitlement is missing from the app's signature"​?
If you are not using Push notifications in your app, this Unity Asset does the job of
fixing this error: ​https://www.assetstore.unity3d.com/en/#!/content/59160​. Just import
it, and build the xcode files again.
16. iOS - How can I fix the error message: ​"This app attempts to access
privacy-sensitive data without a usage description. The app's Info.plist must
contain an NSCameraUsageDescription key with a string value explaining to
the user how the app uses this data."​?
Open the Info.plist file in xcode, and manually add "NSCameraUsageDescription"
(Privacy - Camera Usage Description), with a value explaining the reason why you
are using the webcam. In our case, this was caused by using the Google Cardboard
code and that needs the webcam to read the Cardboard device QR code, so we
added the following value "Requires camera for reading Cardboard QR code".
17. Android - Why doesn’t my huge video file play from StreamingAssets folder?
Files in the StreamingAssets folder for Android are packed into a JAR file and so
before we can play them we must extract them to the apps persistent data folder.
Huge files can take a long time to extract and copy and sometimes they could even
cause the device to run out of storage space or memory. For really large files we
recommend placing them the videos in other folders on the device and then
referencing the absolute path to that file. This also has the added benefit of not
having a copy huge files and wait ages when deploying builds to the Android device.
18. Android - Why does the adb logcat receive so many logs “getCurrentPosition”
from MediaPlayer-JNI?
56 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

Android’s MediaPlayer logs this to verbose channel, simply change your logging filter
to ignore verbose logs.
19. Android - Why doesn’t the video display when using Vuforia?
In our test Vuforia doesn’t play well with AVPro Video when multi-threaded rendering
is enabled. Simple disable this option in the Player Settings screen.
20. Android - Why does my build fail with a message about DEX and zip classes?
This can happen when there is a conflict in the Java code. We include a JAR called
zip_file.jar which contain classes for handling zip files. If you have another plugin in
your project that also contains these classes then Unity will fail the build. Read the
exact Unity error message and if it is related to zip classes then you can try deleting
zip_file.jar file.
Or you may need to upgrade from JDK 1.7.0 to 1.8.0
21. Cardboard/Google VR - Why is the image shaking?
We’ve had reports that this is caused by enabling the option “track position” in the
Gvr head.
22. iOS - Why do I get this message about privacy permission using camera?
Some users have reported getting this message:
“T
​ his app attempts to access privacy-sensitive data without a usage

description. The app's Info.plist must contain an NSCameraUsageDescription
key with a string value explaining to the user how the app uses this data.”
This seems to be a bug in Unity 5.4.1 and has been resolved in Unity 5.4.2.
23. Will you support MPEG-Dash or another adaptive streaming system?
MPEG-Dash is currently supported on Windows 10 and Windows UWP 10 only. ​We
hope to improve support for these sorts of streaming systems eventually. It’s
currently not high on our list of priorities. The plugin already supports some basic
streaming protocols and for now we’re focusing on basic features before we look at
advanced features such as these. HLS adaptive streaming is supported on most
platforms.
24. Android - Why is my video playback freezing?
We have found that H.264 videos with GOP = 1 (all I-Frames / Key-frames) freeze on

57 / 77
AVPro Video © 2016-2017 RenderHeads Ltd

Android. GOP interval of 2 seems to be fine.
25. Why can’t I stream HLS at 4K in Windows 10?
Windows 10 (before Anniversary update) seems to limit the stream resolution based
on your screen resolution and the monitor DPI scaling setting. To get 4K using HLS
you need a 4K monitor and your DPI scaling set to 100%. This issue now seems to
be resolved in the latest version of Windows 10.
26. Why does the video control react correctly in Windows 7, but not in Windows 8
or above?
If you try to call video control function (eg Seek, Mute, SetVolume etc) just after you
open the video file, this can cause problems. Video loading can be synchronous or
asynchronous, so you need to wait until the video has completed loading before
issuing any control commands. In Windows 7 and below the DirectShow API is used
by default. Currently the open function works synchronously, so control functions will
work immediately after loading. In Windows 8 and above the Media Foundation API
is used by default, and this is asynchronous. The best approach is to use the event
system to wait for the video to be ready (contain meta data), or to poll the
MediaPlayer (Control.HasMetaData()) before issuing control functions.
27. Why does my HLS / RTSP stream created with FFMPEG work so badly in
AVPro Video?
Some users have reported issues with creating a stream with FFMPEG where the
stream will take a long time to connect and will only send through frames
occasionally. We have found that you need to manually add the GOP size
parameters to be a multiple of your frame-rate. So for example if your frame-rate is
25 then you should add “-g 25” in your FFMPEG command-line.
28. Which DRM content protection schemes does the plugin support?
See the DRM section in this documentation.
29. Why doesn’t the plugin support Windows XP SP2 and below?
Modern Visual Studio compilers require XP SP3 as a minimum. One of the reasons
for this is builds reference the function GetLogicalProcessorInformation() in
Kernel32.dll which isn’t present in XP SP 2. The lack of this function causes our DLL
to fail to load. More information here:
https://connect.microsoft.com/VisualStudio/feedback/details/811379/
30. What’s the difference between your different Unity video playback plugins?
We previously had 3 video playback plugins for Unity:

Version 1.5.22 - 14 February 2017
○ General

Improved performance of CubemapCube component. Due to
a typo it would previously regenerate the cube mesh each
frame.
■ Improved the fix for Unity 5.4.2 and above where changing
texture quality during runtime would cause the video texture to
turn black. The expensive fix now doesn’t apply to Unity 5.4.1
and 5.4.0, and can be disabled in the global options
■ Fixed bug in subtitles that would cause them to go blank for a
frame
Workflow
■ Android OES path now displays hint about using correct
shaders
■ Error message display is more detailed
■ Improved user feedback when selecting stereo packing to
warn about the need for the UpdateStereoMaterial component
■ Improved UI for UpdateStereoMaterial component to give more
feedback about its setup

■ Better reports error when a video fails to decode due to
insufficient resources
■ Added option to not show the “poster” frame, leading to faster
start and less resource usage for loaded videos. A video that
is loaded but not played and not displaying the poster frame
will not engage the decoder hardware and use up resources

(default in Unity 5.5.0 and above)
■ Cached texture pointer for improved performance
■ Fixed subtitle loading by changing to use a coroutine
Windows
■ Added new events for when a stream has stalled and resumed
- useful for detecting connection loss when live streaming
■ Added new option to generate texture mipmap levels
automatically - this reduces aliasing when the texture is scaled
down
■ Updated Snappy library (used in Hap codec) to latest 1.1.4
which has 20% decompression speedup
■ Fixed bug in DirectShow where calls to SetMuted() or setting
very low audio volume would be ignored
UWP / Windows Phone / Hololens
■ Added new option to generate texture mipmap levels
automatically - this reduces aliasing when the texture is scaled
down
Breaking Changes
■ For Android if you previously loaded videos in a paused state
to see the initial “poster” frame now you’ll need to tick the new
“Show Poster Frame” option in the Platform Specific settings.
In previous versions this was enabled by default, but now it is
disabled by default as it has performance implications.
