Indeed, I can confirm this. ffmpeg is able to insert the per-track "title", but not able to extract it. (Technical detail: it's the "name" atom beneath the "udta" atom beneath the "trck" atom.) > Maybe this is a designed behavior of ffmpeg/ffprobe. > Or a bug ? A shortcoming. I'm able to change the ffmpeg source code to parse the per-track title, but cannot get it inserted properly in the demuxer metadata.
