It most certainly is. But maybe the answer is that it depends. Apparently the file format plays a part in this. > Here is the command I tried: > > ffmpeg-3.1.1 -i multi.mp4 -y -map 0:v -map 0:a -codec copy > -metadata:s:a:0 > title="Foo" -metadata:s:a:1 title="bar" multi2.mp4 > > But the metadata does not show in the output probe: It is the same for me. I just reproduced this here. But when I use matroska (.mkv) as output format, it does work. So, if you are not dependent on mp4 as container format you can at least work around this. I don't know why it does not work with mp4. I think it should but I know too little about this format. > What am I doing wrong? Is this even possible or am I flogging a dead > horse? Not necessarily a dead but perhaps the wrong horse. ;) Peter _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
