  • Other interesting software

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    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.

  • How do I transform python AudioSegment extraction to an ffmpeg command?

    22 March 2021, by Alexis Wilke

    I have a python script which loads an MP4 file and saves the audio to an OGG file like so:

    


    movie = AudioSegment.from_file(f"movie.mp4", format="mp4")
movie.export(f"audio.ogg", format="ogg")


    


    I want to extract that to a bash script which will run once at the we create our Debian packages. To do so, I prefer bash and no python. Is the following command equivalent?

    


    ffmpeg -i movie.mp4 -vn audio.ogg


    


    It seems to work (the audio sounds the same), but I wanted to make sure that it was as close as possible to the original conversion. The resulting files can't just be compared apparently.

    


  • FFMEPG Audio Encoding, How to get optional frame_size of the CodecContext and get right ouput

    23 October 2014, by 程栋彬

    I’m trying to encode pcm format audio using ffmpeg, because the pcm data is of FLTP format, I use audio codec AV_CODEC_ID_AC3 or AV_CODEC_ID_MP3, when I use avcodec_open2(pCodecCtx,pCodec), the pCodecCtx->frame_size was set by this function, for example, it is set as 1536. But the pcm data I get was saved by frame_size = 512. I don’t to do the data transfer, so I just change pCodecCtx->frame_size to 512 after avcodec_open2(), but the output encoded audio sounds wrong.

    So how to encode audio with optional frame_size when the input is pcm data saved in FLTP format?

    aacenc: mark coders other than twoloop as experimental

    ANMR has some interesting things coming up but is currently not in a
    
shape fit for non-experimental usage. Same with "FAST".
