  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.

  • ffmpeg extracting frames from a 60 fps video

    15 juillet 2022, par ggt bnd

    I would like to extract frames from a 60 fps video, all of them I used the ffmpeg code
sevral times on lower fps videos
' ffmpeg -i test.mp4 -qscale:v 1 -qmin 1 -qmax 1 -vsync 0 tmp_frames/frame%08d.jpg "
and it works just fine, knowing that the default fps is 24
how can I change it so it extract at 60 fps
ffmpeg version " ffmpeg-2022-07-06-git-03d81a044a-full_build "

    


  • getting errors from FFMpeg when spawned from .NET

    18 mars 2014, par Brannon

    When I run FFMpeg from the command line like this

    ffmpeg.exe -hwaccel auto -re -i "C:\Users\Public\Videos\Sample Videos\Wildlife.wmv" -an -sn -c:v bmp -pix_fmt bgr24 -f rawvideo - > junk.bin

    it works fine. However, when I spawn the exact same thing (minus > junk.bin) I get this nasty "bad header" error after a few seconds of playback. What is causing this ? I have trouble believing my process blocks the pipe longer than the filesystem does, but it should be able to block the pipe indefinitely without defeating the decoding. The truncated stderr is below. My code to spawn the thing is here.
