  • FFMpeg and WebM/VP8

    25 novembre 2011, par Anand Suresh

    I am trying to use ffmpeg and ffserver to stream VP8 video.

    I am using the following command to start FFMpeg :

    ffmpeg -v 9 -loglevel 99 -f x11grab -s 1440x900 -r2 -i :0.0 -f webm http://localhost:8090/feed1.ffm

    The above command abruptly terminates generating the following error :

  • Adjust framerate MPG4 in ffMpeg

    15 décembre 2015, par Gilles

    I’m trying to create a MPG4 movie from a bunch of png’s. I want the movie to show one of the PNG-pictures every 1/5th second. So I tried the following command :

    ffmpeg -i ffmpeg_temp/%05d.png -r 5 video.mp4

    Now I get a movie of only 40 seconds, in which lot’s of frames completely disappear.

    I have around a 1000 pictures and want that to be a movie of around 3 minutes (5 fps).
