The eight-part craft-video series landed as one commit, because each part's branch contains the parts before it. - #702 dnx: DNxHD/DNxHR decoder and encoder - #703 vp8: VP8 decoder - #704 prores: ProRes decoder and encoder - #705 h264: H.264 encoder - #706 hevc: HEVC encoder - #707 vp9: VP9 encoder - #708 av1: AV1 encoder
