I successfully compiled the lib-decoder-ffmpeg AAR, but noticed that the createDecoder function in ExperimentalFfmpegVideoRenderer has not been implemented.

In the createDecoder method, it directly returns null instead of a corresponding Decoder. How should I modify the compile build parameters so that it returns a decoder? Or is this decoder something I need to implement myself? My current requirement is to integrate the FFmpeg decoder to achieve more powerful video decoding capabilities, but at the moment I’m not sure how to proceed.

lib versions:
media3: main branch, commit: 8ec10ba
ffmpeg: release/8.0, commit: e322e2e

Hi @suifengczc,

Currently, the FFmpeg extension only supports audio. The ExperimentalFfmpegVideoRenderer is not yet functional, as noted in the Javadoc. You would need to implement your own video decoder to use it.

There was a previous attempt to add video support, but it was not merged, and there is no current timeline for its implementation as it's a low priority
