Udon Video Decoder

Udon Video Decoder is a library for loading videos generated by Pixel Proxy, allowing you to load arbitrary API calls into VRChat.

See VideoDecodeExample.cs for a complete usage example.

Some demos are available in the Udon Video Decode Demo VRChat world.

Dependencies

• VRCSDK3
• UdonSharp
• Optionally UdonDecodeLib and UdonXML for decoding the received data.

Scene Setup

1. Create an empty GameObject in your scene and attach the VideoDecoder.cs script to it.
2. Pick a Render Texture and Blank Texture in the Video Decoder settings. Some preset ones are provided with this package. If you make your own, make sure that:

• These textures match in size.
• The blank texture has Read/write enable.
• The Blank Texture has Compression disabled.

3. In your own program, define a variable like public VideoDecoder videoDecoder.
4. Assign the Video Decoder GameObject to this variable.
5. You can now call videoDecoder.LoadURL to load your data.

• callbackBehaviour: The UdonSharpBehaviour that the following callbacks reside in.
• callbackField: Name of field to put the returned data on. Type of this field should be byte[].
• callbackMethod: Name of method to call on success.
