  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

    It solved few problems before.

    I tried to install ffmpeg like here -> https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide, but it is without change.
    Can someone help me with these errors ?

  • Streaming Webcam using VLC +FFmpeg over lan - Error : cannot pre fill buffer

    23 juin 2016, par user1804015

    I’ve been trying to stream my webcam over lan using VLC and FFmpeg

    but I end up with the error "Main stream error : cannot pre fill buffer"

    Here is the code I’ve tried

    ffmpeg -f x11grab -s 1680x1050 -r 30 -i :0.0+0,0 -vf "movie=/dev/video0:f=video4linux2, scale=180:-1, setpts=PTS-STARTPTS [movie]; [in] setpts=PTS-STARTPTS, [movie] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" -f alsa -ac 2 -i pulse -vcodec libx264 -preset ultrafast -s 1280x768 -acodec libfaac -threads 0 -f mpegts - | vlc -I dummy - --sout '#std{access=http,mux=ts,dst=thalha:3030}'

    And this is the output

  • FFMPEG Error while opening decoder for input stream

    6 mars 2016, par Chris

    While this command his been working for a couple of months, I suddenly began running into the following error when encoding video via my php application. Testing the encoding parameters on the command line yielded the same results, while the verion of ffmpeg on my local machine has no problem reading the input

    Command I used :

    ffmpeg -i clip_20121022150813.mp4 -acodec libfaac -ab 44100 encoded.mp4

    And the output (error on last line) :

Error while opening decoder for input stream #0:0

    I have uninstalled ffmpeg, recompiled from source, also recompiled x264 and a host of other libraries, but this error persists. Is there anyway I can find out more about what exactly is failing ?
