FFmpeg
FFmpeg is a popular open-source multimedia framework commonly used for audio/video encode and decode functionality to a variety of codecs.

- avformat/mpegts: add support for ATSC E-AC-3 streams
Scott Theisen: ATSC A/52:2018 Digital Audio Compression (AC-3, E-AC-3), Annex G defines stream_type 0x87 for E-AC-3 bit streams. - avcodec/mediacodecenc: add async mode support
Zhao Zhili: It has better performance than poll in a loop. - avcodec/mediacodec_wrapper: add async mode support
Zhao Zhili - avcodec/mediacodecenc: Add operating_rate option
Zhao Zhili: For example, with ./ffmpeg -operating_rate 400 -hwaccel mediacodec -i test.mp4 -an \-c:v h264_mediacodec -operating_rate 400 -b:v 5M -f null -The transcoding speed is 254 FPS. - avcodec/mediacodecdec: Add operating_rate option
Zhao Zhili: The codec wants to know whether the usecase is realtime playback or full-speed transcoding, or playback at a higher speed.

Leo Izen: The JPEG XL parser has an entropy decoder inside, which supports LZ77 length-distance pairs. - avcodec/amfenc: add support for QueryOutput wait
Cameron Gutman: Enable waiting in QueryOutput() based on driver support to reduce unnecessary delays. - libavutil/hwcontext_{d3d11va, dxva2}: Support Y212/XV36 pixel format
Fei Wang: Use DXGI/D3DFMT 16bit pixel format to compatible with 12bit Y212/XV36 since there is no 12bit pixel defined in D3D11/D3D9. - swscale/swscale_unscaled: add unscaled rgb to planar rgba
James Almer: The fate test reference changes are due to the conversion being a simple lossless deinterleave, instead of going through a RGB -> YUV -> RGB roundtrip. - swscale/swscale_unscaled: add unscaled hbd planar RGB to x2rgb10le
