Comment (by Rodeo): In my experience, Quick Sync is most useful when it handles both video decoding and encoding (much lower CPU usage, fan noise and power consumption) - and that's where Quick Sync will outperform x264 ultrafast by a large margin on consumer-grade hardware. Still, Quick Sync encode- only can also outperform ultrafast on just about any ultrabook, AFAIK. FWIW, there is ongoing to work to integrate QSV as a hwaccel in Libav: https://github.com/maximd33/libav/tree/qsv https://github.com/DonDiego/libav/tree/qsv Only H.264 decode is implemented so far, IIRC - haven't been following this very closely though. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/2591#comment:7> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://avcodec.org/mailman/listinfo/ffmpeg-trac
