I have an mp4 file with a video stream and an audio stream. The audio stream has a title that is shown both by VLC and by Mediainfo.

If I open this file (or any other mp4 file with audio track titles) with this ffprobe command

ffprobe -i input.mp4 -show_streams

the title tag is missing. Even if I set the track title with ffmpeg -metadata:s:a:0 title="my title", the title tag is added/edited correctly by ffmpeg but ffprobe still doesn't see it (other media players do however).

Is this a bug with ffprobe? How can I get audio streams title tag to show?

Thanks in advance

  • Do you mean StreamTitle tag? Is it shown by ffprobe -v error -show_entries format_tags?

If a stream has a valid tag called "title", ffprobe should show it near the end of the stream listing. Even if you only enter ffprobe input.mp4, ffprobe will show stream titles like this, the same way ffmpeg does:

Stream #0:1(eng): Audio: dts (DTS), 48000 Hz, 5.1(side), fltp, 1536 kb/s (default)
      title           : English DTS Core 5.1 Surround @ 1536kbps

Perhaps the 'title' you're seeing in VLC and mediainfo is entered in some other way.

  • Thanks for your answer. Unfortunately my ffprobe (latest version) does not show the title row like in your example for mp4 files that have a valid title tag (and I know that tag is present because mediainfo and vlc show it, and because I have explicitly added it with ffmpeg)

  • Does ffmpeg show it? Apr 28, 2021 at 14:46
  • I've been able to confirm this. What I see is: (1) Most stream titles do not appear, though some appear as "handler_name". (2) Problem is with mp4s, not with mkvs. (3) Problem in ffmpeg and ffprobe. (4) I have two versions, problem in both: version N-100776-g2687070d9b and N-101189-g5a4f0d9b94. To do a bug report for ffmpeg, they will want you to compile the latest head version to make sure it hasn't already been fixed. Apr 28, 2021 at 17:01
  • Also, when you add a stream title tag, it is shown in the output section of the ffmpeg output, and mediainfo can read it, but ffmpeg/probe can't see it when they look at the file. Apr 28, 2021 at 20:03
  • I should have specified that the problem only verifies with mp4, not on mkv. What you say in your last comments is exactly what I have experienced
