    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • FFMPEG not recognising -crf or -qp

    23 avril 2021, par Benj

    I am trying to make a losslessly encoded mp4 video out of png images.

    


    I have a folder of images named frame-%d.png.

    


    ffmpeg -i frame-%d.png -framerate 30 -c:v libx264 -crf 0 output.mp4

    


    FFMPEG rejects crf and qp with the message :

    


    ffmpeg -i frame-%d.png -framerate 30 -c:v libx264 -crf 0 output.mp4

  • VLC can read mp3 but FFMPEG "could not find codec parameters"

    9 septembre 2021, par Be Chiller Too

    I'm trying to process some audio with PyDub, but encountered an error, that seems to stem from ffmpeg, so I investigated, tried to process the audio file directly with ffmpeg and I reproduced the error :

  • How can I add chapters to .mp4 files using a python script ? [duplicate]

    7 mars 2023, par Random

    Is there an easy way to add chapters (i.e. : sections with titles) to .mp4 files using a python script ?

    


    For example, the script could process a 3-minutes video and label the first minute as "Beginning", the second minute as "Middle", and the last minute as "End".

    


    The only solution (link) I stumbled upon so far involves using a ffmpeg command on the command line to extract the original ffmetadata from the video file before appending the chapters to it and updating the video with it.

    


    However, I would like the process to be automated using a python script (instead of having to use the command line each time I have to process a video).
