[FFmpeg-devel] [PATCH v2 1/5] fftools/ffmpeg_demux: honor -ch_layout options for overriding input stream channel layout

The code only set the channel layout of the AVFormatContext, so the user could not override the channel layout if the demuxer did not have such parameter. This used to work via the respective AVCodecContext option, but since 639c2f00497257cb60ecaeeac1aacfa80df3be06 it no longer gets passed to the

[FFmpeg-devel] [PATCH v4 1/2][GSoC 2024] libavcodec/x86/vvc: Add AVX2 DMVR SAD functions for VVC

Implements AVX2 DMVR (decoder-side motion vector refinement) SAD functions. DMVR SAD is only calculated if w >= 8, h >= 8, and w * h > 128. To reduce complexity, SAD is only calculated on even rows. This is calculated for all video bitdepths, but the values passed to the function are always 16bi
