Hello All, I don't understand how ffmpeg/ffprobe manage some metadata of audio streams.
Let's take a simple example : ffmpeg -i INPUT.mp4 -c copy -metadata:s:a:0 "title=5.1" OUTPUT.mp4 The result is : 1- ffprobe is not able to retrieve the audio title of the resulting file, whatever are the options used (I don't know if there are undocumented options) 2- VLC does retrieve the audio title correctly 3- exiftool does retrieve the audio title too I tried to do something similar with a subtitle stream and I had the same result. I am not a developper. Therefore I cannot read the source code. Maybe ffmpeg stores this metadata in a place where ffprobe is not able to retrieve it. Does somebody know if this is a normal behavior ?
