Description Pete Zaitcev 2007-03-19 14:06:50 EDT
Description of problem:

While playing a DVD (unencrypted) with multiply sound tracks, switching
between tracks kills the sound.

Version-Release number of selected component (if applicable):


How reproducible:

Seems like 100%

Steps to Reproduce:
1. Play "Excel Saga" volume 1 (any ADV release will work, they
   are all unencrypted).
2. Switch from English to Japanese.
3. Sound is dead.
Actual results:

Sound is dead.

Expected results:

Japanese sound track.

Additional info:

The switch is done with Sound->Languages->Japanese.

This function used to work in FC-5. Sorry, I didn't test any newer releases.

How did you launch totem? Do you see any errors on the command-line?

If not, please attach the output of "GST_DEBUG=*:2 totem" and reproduce the problem.
Comment 2 Bastien Nocera 2007-03-19 14:31:56 EDT
In bug 232971, you don't mention having the gstreamer-plugins-ugly package
installed, which means that AC3 decoding is done (probably badly) through
ffmpeg. Could you try and install gstreamer-plugins-ugly (from livna as well),
and let me know whether it fixes it?

(The 2 audio tracks are probably in different formats, one in PCM audio, the
other in AC3).

GST_DEBUG=*:2 totem dvd://2

This is the result of:
 GST_DEBUG=*:2 totem dvd://2 >totem.run 2>&1 </dev/null
Nothing obvious has changed in the output when the sound died.
Exactly the same thing kept scrolling before and after.
Comment 4 Pete Zaitcev 2007-03-19 15:38:17 EDT
Looks like gstreamer-plugins-ugly is installed, and its architecture
is compatible:

[root@niphredil zaitcev]# rpm -qa --queryformat
"%{name}-%{version}-%{release}.%{arch}\\n" | grep gst
[root@niphredil zaitcev]# rpm -qa --queryformat
"%{name}-%{version}-%{release}.%{arch}\\n" | grep totem
[root@niphredil zaitcev]#

Japanese often ship DVDs with PCM audio, and actually I have a few.
But this one is an R1. I ran mplayer -v dvd://2 and it printed this:

DVD successfully opened.
audio stream: 0 format: ac3 (stereo) language: en aid: 128.
audio stream: 1 format: ac3 (stereo) language: ja aid: 129.
audio stream: 2 format: ac3 (stereo) language: en aid: 130.
audio stream: 3 format: ac3 (stereo) language: ja aid: 131.
number of audio channels on disk: 4.

Totem correctly shows 4 tracks in its menu, only it names them
"English", "Japanese", "en #2", "ja #2".
