  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • 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.

  • FFMPEG options for video streaming

    26 février 2014, par YorgZ

    I am trying to use ffmpeg to stream video using ffserver. You will find below the ffserver1.conf file, and the log output from the ffmpeg command.

    One of the errors references presets, and everytime I try to use presets I get the error "File not found, even after copying all the preset files in the current directory.

    Thanks for the help.
