    I have made a simple VR movie player on the Quest 2. The movies are h265 files stored locally on the device. I load them in a videoplayer component through url. The videoplayer uses a render texture attached to a skybox material so the movie play 360.

    After 30 or so cycles of preparing and playing movies, the video player is not able to load any new video and I receive this error in Unity :
    W Unity : AndroidVideoMedia::VideoDecoder::ConsumeOutputBuffers bad buffer index: -10000

    And these errors in logcat :
    08-08 12:34:25.179 833 8229 E OMX-VDEC-1080P: Failed to call streamon on OUTPUT

    Since it always happen after XX cycles, I guess some memory is full. I dont see any problem in the profiler, so the RAM must be OK.
    Anyone has experienced this or could give me an hint where to look further?

    I'm using Unity 2021.3.7f1

    Thank you!

    Can you try on using 2022.2+? I know we made some changes related to h265 on android, and we didn't backport it yet.

    Thanks for the hint. Same results with Unity 2022.2. And the same happens with h264 movies.
    When a video is loaded with URL, where is it stored? In the RAM? When I do a Memory profiler snapshot, what should I look for?

    I am reading on the error code, and I see multiple reports in Exoplayer (same backend) with issues similar to what you have. Some people say it is maybe related to not correctly releasing the codec. I am pretty sure we are releasing the codec, but the issue could be with the API. Can you submit a bug report? We will try to investigate
    Is there a reason you need to prepare the VideoPlayer 30 times? Could you pause and seek at the start as a workaround?
    It is probably hardware accelerated, so the textures are probably stored on the GPU, not the RAM.

    Hi!
    I am experiencing exactly the same problems. I got an app, where you travel between various 360 3D video locations. eventually the video player freezes.. Did you find any solution for this?

    If you can reproduce it, you should open a bug report.
