  • find in bash to convert files with ffmpeg - paths being changed

    20 avril 2017, par J V

    Trying to convert a bunch of files with ffmpeg and find.

    find -name "*.mkv" | while read f
    
do ffmpeg -i "$f" -c copy -y "${f%.*}.mp4"
    
done

    This should work right ? It results in :

    + read f
    
+ ffmpeg -i '/file.mkv' -c copy -y '/file.mp4'
    
ffmpeg version N-61155-g61ff043 Copyright (c) 2000-2014 the FFmpeg developers
    
  built on Mar  7 2014 19:17:59 with gcc 4.8 (Debian 4.8.2-16)
    
/file.mkv: No such file or directory

    So I naturally try sticking the missing dot in front of the variable :

    find -name "*.mkv" | while read f
    
do ffmpeg -i ".$f" -c copy -y ".${f%.*}.mp4"
    
done

    The result :

    + read f
    
+ ffmpeg -i '../file.mkv' -c copy -y '../file.mp4'
    
ffmpeg version N-61155-g61ff043 Copyright (c) 2000-2014 the FFmpeg developers
    
  built on Mar  7 2014 19:17:59 with gcc 4.8 (Debian 4.8.2-16)
    
../file.mkv: No such file or directory

    It’s specifically removing the dot at the worst possible time. Any idea what’s causing this and how to fix it ?

    PS : -print0 in find has the same problem, and none of the files have newlines etc.

    Edit : As requested, the echo. The echo works as expected :

    find -name "*.mkv" | while read f
    
do echo ffmpeg -i "$f" -c copy -y "${f%.*}.mp4"
    
done
    

    
+ read f
    
+ echo ffmpeg -i './file.mkv' -c copy -y './file.mp4'
    
ffmpeg -i ./file.mkv -c copy -y ./file.mp4

    Edit2 : With a file with a space and one without, the filename without is changed. If I rm the one with a space the one without works fine.

    $ ls
    
+ ls
    
file.mkv  file two.mkv
    
$ find -name "*.mkv" | while read f; do ffmpeg -i "$f" -c copy -y "${f%.*}.mp4"; done
    
+ find -name '*.mkv'
    
+ read f
    
+ ffmpeg -i './file two.mkv' -c copy -y './file two.mp4'

  • How to find out the file extension for extracting audio tracks with ffmpeg and python ?

    6 juin 2018, par seenorth

    I want my python program to extract the audio tracks from various video files without changing the audio codec. For this I call the following command :

    ffmpeg -i "input" -vn -acodec copy "output.???"

    However this only works, if the file extension of the output file is known. Is there a way to find out the corresponding file extension ?
