  • 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 :
