I can confirm this bug. It is a regression. Hopefully this is fixed by version 1.6.

This is still occuring in version 1.5.1, except I noticed that it only seems to occur to some FLAC files, and seeking to certain locations within those FLAC files still works, just that seeking to most locations do not. Will provide more detailed output later. This might be related to bug 586976.

Confirming in git master. I cannot seek any of my flac files. Seeking just stops playback without any errors or warnings.

Exactly the same symptoms as Alexander. Confirmed.

I too cannot seek in any FLAC files. This is a very annoying bug.

I assume you all are able to seek in your FLAC files in Totem and/or Rhythmbox - eg that this is indeed a Banshee issue and not a GStreamer one.

Yep, the same FLAC files seek fine in Totem but don't seek at all in Banshee.

Yes.  In fact, when I need to seek in a FLAC file, I will load it in Totem.

Is any work being done to fix this bug? Sorry for asking, it's just that a large part of my music library is in FLAC, and I would really like to see this fixed by version 1.6.

The patch from bug 600072 fixes this bug as a side effect. Adding as a dependency.

The patch has been removed from that page. I confirm this bug to persist in 1.5.4 also. Seeking does not work but at extremely rare occasions.

The branch called 'gapless-ng' also fixes this. It should hopefully be merged back to master before 1.6. See bug 440952 for details.

Should be fixed by the gapless-ng branch which is now merged into master.

Created attachment 156698 [details]
Debug output

The problem seems to persist in release 1.5.5 and the current git master.

Steps:
1. Run banshee-1 --debug
2. Start FLAC song.
3. Use seek slider.
(4. Quit banshee)

Result:
Mostly the playback stops. Sometimes some not recognizable (because very short) fraction of the song is played and playback then stops. Very rarely playback continues (at the right position).

The output of the procedure above is attached.

> The problem seems to persist in release 1.5.5 and the current git master.

Which version of gstreamer you have installed? Do you have "Enable gapless playback" checked in preferences?

Thanks for the response.

I missed the parameter --enable-gapless-playback when I ran configure. Now I fixed that, updated gstreamer and enabled gapless playback in the banshee preferences. Now lines like

[Debug 20:54:45.129] (libbanshee:player) [gapless] Triggering track-change signal

appear in the output of banshee-1 --debug.

As opposed to before, the playback seems to be gapless now. But I still have a problem with seeking. Seeking works more often but far from always.

My gstreamer versions (on gentoo)

media-libs/gstreamer (0.10.28)
media-libs/gst-plugins-bad (0.10.17)
media-libs/gst-plugins-base (0.10.28)

media-plugins/gst-plugins-x (0.10.25)
media-plugins/gst-plugins-xvideo (0.10.25)
media-plugins/gst-plugins-soundtouch (0.10.17)

Now, with media-libs/gst-plugins-good 0.10.21 and media-plugins/gst-plugins-flac 0.10.21, everything works fine.

I can confirm that both Seeking in FLAC files and gapless playback works with the latest gstreamer(.10.10-1) and Banshee (1.6.001) in Ubuntu Lucid Lynx 10.04
