    Per the ffmpeg documentation I'm trying to switch the video's audio output to japanese. However, the output video is still in english (which it was in before). This is my current ffmpeg cmd :

    


    ffmpeg -i "my_vid.mp4" -c copy -disposition:a:1 default "output.mp4"


    


    what am I doing wrong ? Still pretty new to ffmpeg

    


    Edit :

    


    With one of the suggestions I tried adding the -map 0 option to my command

    


    ffmpeg -i "my_vid.mp4" -map 0 -c copy -disposition:a:2 default "output.mp4"


    


    but still not change. The meta data for the output video is as follows :

    I want to add a subtitle track on a ProRes files with ffmpeg command on Windows :

    


    ffmpeg.exe  -i "X:\Test\Tokyo01.mov" -i "X:\Test\SubtitleEN.srt" -f mov -c:v copy -c:a copy -c:s mov_text -map 0:v -map 0:a -map "1:0" "-metadata:s:s:0" "language=EN" "-metadata:s:s:0" "handler_name=English"  "-metadata:s:s:0" "title=English" -y "X:\Test\Tokyo01_WithSub.mov"

    I don't find documentation for mentionned command "-video_track_timescale" to change timescale (here 1/90000 ).
I don't understand the problem ??
