#11363: [Android] MediaCodec decoders/encoders do not work on Pixel 8 Pro (No
output buffer available)

-------------------------------------+-------------------------------------
I cannot get MediaCodec hardware encoders/decoders to work on my Pixel 8
Pro (Android 15), while it works perfectly on my Pixel 4a (Android 13)
At the end of this report is the logs of a failure to decode a simple mp4
file with h264_mediacodec, using a custom build of ffmpeg for Android from
the snapshot from Dec 19th.
It fails and get stuck on "No output buffer available, try again later",
repeated indefinitely. Speaking of which, exiting with the 'q' key does
not work, I have to force kill it with 3 CTRL-C.
The h264 hardware encoder does not work as well, stuck in the same way.
I have tested that hw encoders/decoders work properly with an external
tool making use of the MediaCodec API directly:
https://github.com/JohanBlome/encapp/
Any hint how I could further troubleshoot this issue ?
