  • Creating farms of unique websites

    13 avril 2011, par

    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • How can I amplify volume with Audacity and ffmpeg ?

    18 octobre 2019, par Christos Hayward

    I have an MP4 recording where the video is present, but much too quiet. What I’ve done before is :

    ffmpeg -i master.mp4 -i amplified.wav -vcodec copy output.mp4

    I’ve tried various permutations, and the output ffmpeg builds is, as viewed by my browser, at the original overly quiet volume. If I load the Audacity-generated .wav, it plays as loudly as intended. (N.B. I have enabled clipping in Audacity, and I have not noticed it to fail at the amplifications I’ve tried with it.) However, the final result seems to retain unaltered the original audio track along in the video.

    How, with present software or other software, can I assign amplified.wav to be the new audio track to master.mp4 in output.mp4 ?

  • FFMPEG Amix filter volume is not constant

    24 mars 2017, par HernanLeandro

    I’m having an issue with FFMPEG and amix filter. Turns out that the volume ins’t constant, the generated audio starts with a lower volume and after each mixed sound ends the volume is higher and higher. I’m having a headache right now hahaha.

    I’m adding the sounds over base.mp3 that is input 0.

    Thank’s !

    Here’s an example of a command line :

    ffmpeg -i /Applications/MAMP/htdocs/public/audio/base.mp3
    
       -i /Applications/MAMP/htdocs/public/audio/n7.mp3
    
       -i /Applications/MAMP/htdocs/public/audio/n7.mp3
    
       -i /Applications/MAMP/htdocs/public/audio/n7.mp3
    
       -i /Applications/MAMP/htdocs/public/audio/n7.mp3
    
       -i /Applications/MAMP/htdocs/public/audio/n7.mp3
