This code was contributed by Intel engineers to upstream FFmpeg just as they have done with the prior oneVPL integration and other video acceleration contributions over the years to benefit their graphics hardware on Linux and Windows.Īccelerated AV1 encode with Intel discrete graphics hardware is available with their DG2/Alchemist GPUs such as the recently launched Arc Graphics A750 and A770 models. On Windows and Linux the QSV API is available via the Intel Media SDK while the Intel Quick Sync Video AV1 encoder is making use of oneVPL underneath as the video processing library that is part of Intel's excellent and open-source oneAPI software suite. Merged this week to mainline FFmpeg is the new "qsvenc_av1" / "av1_qsv" encoder. This AV1 encode path using their Media SDK with QSV is ultimately building atop oneVPL. While Intel contributed oneVPL support to FFmpeg this summer that can be used for video encoding/decoding to AV1 and other formats, this past week Intel engineers contributed an AV1 encode Quick Sync Video (QSV) encoder too for FFmpeg. extra-ldflags="-L$HOME/ffmpeg_build/lib" \ extra-cflags="-I$HOME/ffmpeg_build/include" \ PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig".
