  • Speed of the x265 and ffmpeg HEVC based encoding

    10 mai 2015, par userDtrm

    I’m trying to perform a real-time encoding of a video using HEVC with ffmpeg. I’m able to achieve the required performance when running the x265 encoder separately without the support of ffmpeg. This way the my system can perform the encoding at 30 frames per second. However, my requirement is to create a MPEG-TS stream with the encoded content and therefore, the video is encoded with the ffmpeg as follows :

    ffmpeg -s:v 1280x720 -i input.yuv -c:v libx265 -x265-params crf=20:keyint=25:fps=25:preset=ultrafast -f mpegts out.ts

    Strangely, the performance of the encoding is reduced drastically and I’m only able to achieve an encoding performance of just 10 frames per second.

    Is this a problem of the multiplexing process within ffmpeg ?. Could someone please help me to resolve this issue.

    Thanks.

    Pass this information explicitly instead.

  • ffmpeg : replace custom channel_layout code with an SpecifierOpt based one

    ffmpeg : replace custom channel_layout code with an SpecifierOpt based one
    

    This is cleaner and allows fine tuning which stream the option is applied to.
