  • FFmpeg conversion FROM UYVY422 TO YUV420P

    25 avril 2015, par risque

    I have raw video in UYVY422 format and I want to convert it YUV420p.
    I’am executing that command()

    ffmpeg -y -r 25.0 -f rawvideo -s 1920x1080 -pix_fmt uyvy422 -i input.avi -pix_fmt yuv420p -f avi -r 25 -s 1920x1080 output.avi

    and my output video seems to float(right side of video start to be present at left edge and it is moving from left to right)

    Has anyone got any idea about what I am doing wrong ? I was trying to set output video to raw format, but it didnt work...

  • Optimise ffmpeg hls stream to images

    10 mars 2017, par mrdotb

    I’m using a ffmpeg to convert a hls stream from twitch to 30 png images per seconds on stdout then I load them in python using pillow.

    My ffmpeg command is the fallowing.

    I get a hls stream from twitch using

    livestreamer --http-header Client-ID=mytwitchtoken --hls-live-edge 1 twitch.tv/stream source,1080p60 --stream-url

    Then my images using

    ffmpeg -i streamurl.m3u8 -vf fps=2 -nostats -pix_fmt rgb24 -vcodec rawvideo -f image2pipe -

    The ffmpeg command is working well however it’s resource intensive (100% of my cpu). Is there some optimization I can do on the command or another method to get my images from the hls stream.
