  • ffmpeg : how to extract 1st video, english audio and french subtitle from video file in one command line ?

    15 mai 2020, par Sxilderik

    I have read many posts related to extracting streams per language with ffmpeg, but it seems that the -map 0:m:language:xxx is global, and goes for all streams.

    



    Let’s say I have a video file that contains hopefully one english audio stream and some french subtitle streams, among possibly many other streams. I want to get a smaller file with the first video track, the (first) english audio stream and all the french subtitle streams.

    



    If I run

    



    ffmpeg -i "$file" -map 0:v:0 -vcodec copy -map 0:m:language:eng -acodec copy -map 0:m:language:fre -scodec copy -f matroska "${file%.*}.mkv_out"


    



    I get in file.mkv_out all audio and subtitle tracks which are either french or english.

    



    Is there a way to achieve this, without having any prior knowledge of track numbers in the original file ?

    



    Thanks.

    


  • QuickTime plays separate audio tracks all at once with ffmpeg generated file

    23 mai 2022, par Justin Smith

    Let's say I have four files :

    


      

    • video.mp4

      • 


    • english.mp4

      • 


    • french.mp4

      • 


    • spanish.mp4

      • 


    


    I'm using the following ffmpeg command to create a single video file with multiple audio tracks for each language :

    


    ffmpeg -i video.mp4 -i english.mp4 -i spanish.mp4 -i french.mp4 \
-map 0:v -map 1:a -map 2:a -map 3:a \
-metadata:s:a:0 language=eng -metadata:s:a:0 title="English" \
-metadata:s:a:1 language=spa -metadata:s:a:1 title="Spanish" \
-metadata:s:a:2 language=fra -metadata:s:a:2 title="French" \
-disposition:a:0 default \
-c:v copy -c:a aac output.mp4


    


    The resulting video file output.mp4 works fine in VLC, but the audio tracks play all at once in QuickTime and the separate audio channels don't appear in the Languages menu. What am I doing wrong here ?

    


  • How to keep two languages when using FFMPEG ?

    14 août 2020, par timlwsk

    So, to only keep the english language track, I currently use ffmpeg -i INPUT.mkv -map 0:v -map 0:m:language:eng OUTPUT.mkv, how can I keep the english and german tracks ?
