  • 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.

    lavd/opengl : select the GL context before drawing

    Since “2d924b3a63 fftools/ffmpeg : move each muxer to a separate thread”,
    
opengl_write_packet() is called from a different thread than

  • Volume adjust and channel merge on video using FFMPEG

    6 novembre 2015, par user1566352

    I’m trying to convert a recorded AVI (1 video stream, 2 audio streams[1st is stereo, 2nd is mono]) video file to H264/AAC.

    I want the second audio stream to be at 60% volume and the first at 100%.

    I also want to merge the first and second audio stream.

    Output should be H264 with AAC audio.

    The command I tried to use is :

    "ffmpeg.exe" 
    
  -i "input.avi" 
    
  -filter_complex " 
    
    [0:a:0]aformat=channel_layouts=stereo,volume=1.0[a1]; 
    
    [0:a:1]aformat=channel_layouts=mono,volume=0.6[a2]; 
    
    [a1][a2]amerge,pan=stereo|c0code>

    But I get the error :
    [AVFilterGraph @ 0000000ceb630c00] The following filters could not choose their formats : Parsed_amerge_4
    Consider inserting the (a)format filter near their input or output.
    Error configuring complex filters.
    Error number -5 occurred

    What am I doing wrong and how can it be fixed ?
