Could Android be supported?

[guiglass]

Thank you for creating this wonderful plugin!

I am trying to stream video from one Unity project running on Windows into another Unity project running on Android (on a Quest 2).

After I build the project and run it on the Quest I get an error: DllNotFoundException: uNvPipe

Is there any way that Android could be supported? Or is there any way to make decoding work on Android or a software decoder available?

NvPipe uses NVIDIA-GPU-specific APIs called NVENC/NVDEC, so it is not supported on Android.
One of my friends wrote a native plugin (kotlin-based) to decode this encoded h264 stream on Android, so I think it is possible in principle, but unfortunately the project is closed and not publicly available...

Thank you for replying! I have been trying to stream video from my PC to my Quest 2 in Unity for weeks and have not made any progress. But I do know it is possible to do because I often use a program on the Quest that can mirror my PC's desktop using .h264. I just am not very knowledgeable about working with compressed video in Unity on Android.

I'd be very grateful if there would be any way you could help or any resources you could recommend that might explain how to write a software decoder to decode the h264 stream, or HEVC if possible?

I don't know much about Android either, but he used MediaCodec to do the decoding.

If you use the word "MediaCodec" as a hint and search blog posts or github repositories, you might be able to find something helpful.
