Alpha Video on Android/Quest

[dmennenoh]

I have some Webm/VP8 alpha channel videos I need to play in our app on the quest. Using the Unity Video Player the videos play but drop a lot of frames and just play quite poorly. I tried VP9 encoding them but then they don’t play in the Editor and it’s a huge pain to not be able to see anything. We own AVProVideo from RenderHeads but I’m not sure that is any better…
What’s the best solution? PNG sequence? The videos are relatively short so that is something I’ve been considering.
Thanks.

In general VP8 / Webm is supported on android but transparency is not supported

The .webm file format has a specification refinement that allows it to carry alpha information natively when combined with the VP8 video codec. This means any Editor platform can read videos with transparency with this format.

Because most of Unity’s supported platforms use a software implementation for decoding these files, they don’t need to be transcoded for these platforms.

One notable exception is Android. This platform’s native VP8 support does not include transparency support, which means transcoding must be enabled so Unity uses its internal alpha representation.

I can recommend using AV Pro with alpha packing (side by side for example)
Yes its bigger then the build in packed but the video quality is much better if you use a good codec.

Thank you, I was looking at the alpha packing option in AVPro, good to know it works well.
