  • How to copy metadata during mp4 conversation with FFMPEG ?

    20 février 2016, par IremadzeArchil19910311

    When I am trying to make a video conversation from .m4v to mp4 :
    I know how to select audio streams as well as a video streams,
    Also I know how to copy a few subtitles from input to output !
    But I can not copy a metadata from input to output !

    In order to get my best result I should read myself all streams title and retype it to new files stream !

        ffmpeg -i input.m4v -map 0:v:0 -map 0:a:0 -map 0:a:1 -map 0:a:2 -map 0:s:0 -map 0:s:1 -vcodec h264 -acodec:0 mp3 -acodec:1 mp3 -acodec:2 mp3 -c:s mov_text 
    
-metadata:s:v:0 title="Main Program" -metadata:s:a:0 title="English Stereo" -metadata:s:a:1 title="Russian DVO CTC Stereo" -metadata:s:a:2 title="Ukrainian DVO 2 + 2 Stereo" output.mp4  

    So as you can see I wrote second line in order to get a result, which is very long written by my hand !
    So please tell me how to copy all streams title from input file to output file without retyping ?

    As I can understand we should find out how to select input file`s stream title....

     Like video stream selection is                        -map 0:v:0   or  -map 0:v:1
    
 such that we should have a metadata title selection   -map 0:m:0   or  -map 0:m:1  

    I don’t know !
    Please help me !
