Description Ed Seymour 2010-09-04 20:13:26 UTC
Used Handbrake to rip DVD titles to H.264 / AVC m4v files with the 'Chapter Markers' option set. 

When playing these movies using Totem on Ubuntu 10.04LTS with GStreamer back-end you get an OSD displaying the chapter title. The OSD is persistent and does not time-out.

Similar issue is seen playing movies with Moovida 1.00x which I understand is also backended by GStreamer.
Comment 1 Stefan Sauer (gstreamer, gtkdoc dev) 2010-09-24 10:07:00 UTC
Does it work with other players? Can you attach a screenshot or even make a short version of the file?
Comment 2 Ed Seymour 2010-09-24 10:40:16 UTC
The problem does not occur when m4v file is played with other players such as XBMC or VLC Media Player. I have noticed that PlexApp has started doing this with the latest release (do they use gstreamer?)

Thought you might ask for a sample file :) I'll see if I can create one, might take a few days.
Comment 3 Stefan Sauer (gstreamer, gtkdoc dev) 2010-09-24 11:23:00 UTC
Make a screenshot for a start if that is easier.

Screenshot showing the OSD chapter title

Attached a screenshot showing the chapter title as displayed on the screen. Please note that this issue is with respect to persistent nature of this title, i.e. it is displayed continuously and does not disappear after a few seconds. 

The screenshot shows totem, but I have also seen this issue with other players that appear to be GStreamer based, and not in players that are not, for example VLC and XBMC.
Comment 5 Stefan Sauer (gstreamer, gtkdoc dev) 2010-09-27 08:08:39 UTC
GStreamer seems to treat that chapter-title as a subtitle that is spanning the duration of the clip. Either gstreamer reads the subtitle the wrong way or Handbrake write it the wrong way. I guess we really need a small video to verify.

Which version of handbrake did you used and under which os (linux ?) which linux distro do you run and what are the gstreamer versions. many distros have extra repositories with latest stable gstreamer releases (like the gstreamer ppa for ubuntu). It wound be nice to see if it works with those.

Comment 11 Tim-Philipp Müller 2010-10-08 16:54:55 UTC
Could you make such a rip available somewhere? Or the first 10MB-20MB or so? (enough so that the OSD disappears in other players; create with head --bytes=20m foo.m4v > part.m4v)

Have you tried upgrading to ubuntu maverick? Or added the GStreamer PPA (which has more recent versions of the various GStreamer packages)?

Moving to -good (qtdemux) for now..
Comment 12 Ed Seymour 2010-10-09 11:38:58 UTC
It does appear that Handbrake inserts a subtitles, so it is possible to workaround the issue by turning subtitles off. 

I don't know if there is a problem with the subtitles created by Handbrake or with the way GStreamer displays them. Normally subtitles should disappear after a short period of time.

I've uploaded an example video 15MB as requested.

Comment 13 Tim-Philipp Müller 2010-10-09 12:11:20 UTC
Nice sample file, thanks for that.

Can't even get the subtitles to show in VLC or mplayer, but can reproduce this with totem/gstreamer. (Btw, do we know for sure that the chapter OSD isn't supposed to be persistent?)
Comment 14 Berend De Schouwer 2011-12-05 12:34:40 UTC
It's there to let you skip to the next chapter, not for display.

VLC does that.  FFWD goes to next chapter.  It doesn't display chapters as subtitles.

Totem doesn't let you skip chapters.

PS.  I have no idea if this is an abuse of the spec.

    qtdemux: skip disabled tracks
    
    ISO/IEC 14496-12 specifies disabled tracks should be completely
    ignored, so just do it.
    
    Avoids deadlock during prerolling for some files.
    
    Also prevents 'chapter' subtitle tracks from showing up.

Comment 17 Matej Knopp 2013-03-26 03:41:27 UTC
The specification may say that the track without the enabled flag should be treated as if it were not present, but no player really does it. Both QuickTime and VLC display audio and subtitle track where "Track Enabled" is false. This patch unnecessarily hides playable tracks. There must be a better way to filter out chapter data.
Comment 18 Matej Knopp 2013-03-26 04:00:18 UTC
Looking at they way mp4v2 adds chapter data, the proper way to detect chapter track would be to find tref.chap reference atom in video track (although it could be in other track as well) and match it against the track id for the chapter track.
Comment 19 Tim-Philipp Müller 2013-03-26 10:14:45 UTC
Matej: is your goal to extract/expose the chapter information, or do you have files with other tracks which are now disabled?

The chapter information should be exposed in a different way, using GstToc + event.
Comment 20 Matej Knopp 2013-03-26 12:38:51 UTC
I'm not looking to expose the chapter information, although I might do that later. 

I have some files that are perfectly playable in other players (QuickTime, VLC) but gstreamer now ignores audio and subtitle tracks. I'll post a patch later today.

Patch to detect chapter track and ignore it
Comment 23 Tim-Philipp Müller 2013-03-26 18:16:37 UTC
Can you point me to a file with "disabled" non-chapter tracks that are exposed in quicktime?
Comment 24 Matej Knopp 2013-03-26 19:54:17 UTC
Sure, you can find it here:

https://s3.amazonaws.com/MatejK/disabled-tracks.m4v

Both Audio and Subtitle track have the "Track Enabled" flag set to 0
QuickTime will not play the audio, but does allow to select and enable subtitle track
All other players that I tested (VLC, MPlayer, Movist) allow to select both audio and subtitle track.
