    11 avril 2014, par StackOverFlowMeteor

    I have a video file named "Video.ts" that contain 4 audio languages (English, Chinese, xxx, xxx).

    The ffmpeg shown the original aac audio channels were in the one stream "0:1"
    Can anyone show me the ffmpeg command line to do it ? Thanks a lot !

  • how can i insert an empty subtitle

    22 avril 2020, par Ginso

    i have a bunch of mp4 files and i would like to convert them to mkv, so that the automatic selection auf audio and subtitle track of vlc works.
the thing is some of them have 4 subtitles (first german and english only for foreign languages and then german and english for all) and some of them only 2 (because in those episodes there are no foreign languages). Can i insert 2 empty subtitle tracks before them so that i can set my vlc to select the first or second subtitle when i watch them ?

    



    i convert the episodes with 4 subtitles like this :

    



    ffmpeg -i in.mp4 -map 0:0 -map 0:1 -map 0:2 -map 0:3 -map 0:4 -map 0:5 -map 0:6 out.mkv

    



    0:0 is of course the video

    



    0:1 and 0:2 are audio tracks

    



    the rest are the subtitles

    



    BTW : is there a language code for forced subtitles ? -metadata:s:s:1 language=?
