  • Segmenting .flac files with ffmpeg truncates audio but not file length

    5 avril 2022, par Yan White

    I am trying to get Twitter spaces audio (.ts) files into a format I can easily edit, on OSX.

    


    So far I was able to convert the files in bulk to .flac with this :

    


    for i in *.ts;
do name=`echo "$i" | cut -d'.' -f1`
echo "$name"
ffmpeg -i "$i" -sample_fmt s16 -ar 41000 "${name}.flac"
done


    


    That worked, and reduced the file sizes somewhat, but..
Because most of the files are around 7 hours long, my editor of choice cannot process that much audio in one file.

    


    So I looked around and was able to find this command to segment the files into 3hr long sections.

    


    ffmpeg -i space-1OdKrBealBqKX_0.flac -map 0 -f segment -segment_time 10800 -c copy space-1OdKrBealBqKX_0__%03d.flac


    


    This works, but each file contains as much empty / silent space at the end as the orginal file. That's going to be a problem for sharing with a team that will help edit these files, as each file has the original file's length and file size. There are a lot of files.
The audio segments and naming did work though.

    


    How to truncate the actual length of the file to the audio segment ?

    


    Caveat : I am no expert on any of these matters, I just managed to google and get this far, so if someone knows and wants to provide working code that would be very much appreciated !

    avidec : check for valid bit_rate range

    If bit_rate is negative, it can trigger an av_assert2 in av_rescale_rnd.
    

    Since av_rescale returns int64_t, but st->codec_bit_rate is int, it can
    
also overflow into a negative value.
