[Bug] Hardware Acceleration Decoders (h264_mediacodec) Fail to Load Due to FFmpeg Experimental Codec Refusal on Android Client

Open sunshinewithmoonlight opened this issue 1 month ago • 3 comments

Describe the bug Attempting to use the hardware acceleration decoders, h264_v4l2m2m or h264_mediacodec, on an Android 10 client device results in a decoding error and stream failure. The error message suggests a refusal to open an experimental codec. Specifically, when either of these two decoders is selected, the application crashes or fails to start the video stream, displaying the error shown in the second attached image. The first decoder in the list works but exhibits severe screen tearing and fragmentation (choppy/laggy).

To Reproduce

  1. Launch the SysDVR client application on the Android device.

  2. Navigate to the decoder settings or the decoder selection list.

  3. Select either the h264_v4l2m2m or the h264_mediacodec decoder.

  4. Attempt to connect and start the video stream from the Switch.

  5. The error (shown in the second image) is thrown, and the stream fails to load.

Expected behavior The selected hardware decoders (h264_v4l2m2m and h264_mediacodec) should successfully open and utilize the Android device's hardware acceleration to provide a smooth, tear-free, and stable video stream. Alternatively, if the codec is experimental, the application should pass the necessary flags (like AV_CODEC_FLAG_OPEN_EXPERIMENTAL) to allow it to be loaded, or fallback gracefully.

Setup information

  • Os: Android 10
  • Console firmware: 20.5.0
  • Custom firmware name and version: Atmosphere 1.9.1
  • SysDVR version 6.2.1
  • SysDVR Android client version 6.2.2

Additional context The issue appears to be related to FFmpeg's handling of "experimental" decoders. FFmpeg, which SysDVR uses for decoding, marks the Android hardware decoder (h264_mediacodec) as experimental.

The underlying cause is likely due to the avcodec_open2 function call in the SysDVR client code not passing any options, causing FFmpeg to reject the experimental codec by default for safety:

// Player.cs around line 202
avcodec_open2(codectx, codec, null).AssertZero("Couldn't open the codec.");

The presence of null as the options argument is preventing the necessary flag (e.g., to enable experimental codecs) from being passed, leading to the reported error.

The flag you mentioned "AV_CODEC_FLAG_OPEN_EXPERIMENTAL" does not return any hits on google, wouldn't be surprised if it's some kind of AI allucination.

I enabled the closes thing that i could find in the docs that is FF_COMPLIANCE_EXPERIMENTAL https://github.com/exelix11/SysDVR/blob/96af3d8a593c86c0764e4a9f5e0e9d15b10becce/Client/Targets/Player/Player.cs#L272-L276

You can get this build to test it, note that it's behind the debug.log flag, you need to enable it manually in the settings first.

When it's enabled you should see Setting strict compliance to experimental for the decoder in the logcat output

Thank you for your effort. I tried the version you provided, but it still throws an error. Maybe the issue is on my side?

I think that means the codec is not supported on your OS or maybe it has not been compiled in the ffmpeg build. Sysdvr still uses some outdatet builds from https://github.com/arthenica/ffmpeg-kit maybe you need to make a custom build with support for those codecs or read the docs for any missing requirements.
