  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • 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 ?

  • ffmpeg replace part of audio file with looped audio gives queued buffers

    1er décembre 2015, par user1202648

    I am quite new to ffmpeg and I am trying to replace a part of a first audio file with another second file. The second file can be too short, so some sort of loop should exist.

    After some research I came up with the following command arguments and it gives me the output as long as I only do one replacement. But I would like to do multiple replacements. So any help on what I am doing wrong ? Any suggestions/remarks on the way of working are also very welcome.

    (Any typos in the commands below can be ignored, I generate the command by script and for ease of use I simplified the names.)

    Works (One replacement) :

    "ffmpeg.exe" -y -i "first.wav" -i "second.wav" -filter_complex "[1:a][1:a][1:a]concat=n=3:v=0:a=1,asetpts=PTS-STARTPTS[replaceBase];[0:a]atrim=0:3,asetpts=PTS-STARTPTS[partA];[replaceBase]atrim=0:2,asetpts=PTS-STARTPTS[replaceA];[0:a]atrim=start=5,asetpts=PTS-STARTPTS[partB];[partA][replaceA][partB]concat=n=3:v=0:a=1[aout]" -map "[aout]" Out.wav

    Works Not (Multiple replacements) :
