MP4 Track Names Not Shows During Playback

[Simon88]

Very latest mp4box.exe from Nightly Build of GPAC was used to mux H.264/AAC into an MP4 container. Both standard and latest VLC 1.3.0 Git Nightly Builds will not display Video, Audio, and Subtitle Track Names. Track "lang" are however displayed correctly. User input Track Descriptions are not supported it seems.

Media Player Classic - Home Cinema shows all Track Descriptions, as does Apple Devices.

Is anyone seeing such behavior?

Sample?
hdlr tags are not supposed to be shown...

Hi Jean,

I don't have a sample link per se, as most multi-track online stuff are in MKV containers, but Apple & other portable devices don't like MKV containers.

I labeled a few MKVextracted without re-encoding videos using this command

"C:\tools\mp4box\mp4box.exe" -add "C:\Videos\1.mp4#trackID=1:fps=24.0" -add "C:\Videos\1.Cantonese.mp4#trackID=1:lang=Chinese:name=Cantonese" -add "C:\Videos\1.Mandarin.mp4#trackID=1:lang=Chinese:name=Mandarin" -tmp "C:\\Videos" -new "C:\Videos\1-muxed.mp4"

Do you have access to MeGUI, Yamb, GPAC Framework, etc... which has a compiled mp4box.exe?

Anime/foreign films created by MeGUI in MP4 containers also doesn't show the track descriptions by VLC during playback.

Just did a google search and appears someone last year also mentioned Track names not displayed correctly during playback at:

hdlr.name is not the right way to display a track name. So, either it is that, and I won't do something, or it is different, then you should share a sample.
