Description

Иногда при проигрывании mp3 файлов начинается сабж. Никакого выхлопа в терминал при этом не наблюдается. Движок воспроизведения gst1.0 не влияет: одинаковая проблема с ffmpeg и fluendo.

STR:
openSUSE 13.2 x64, Qt4, gst 1.0, leechcraft 0.6.70-2XXX, mp3, подождать 2-4 трека.

Expected result:
Нормальное воспроизведение без сабжа.

Actual result:
Сабж.

Воспроизводится на Qt5-билде с gst-1.0. Проигрывать mp3 при этом не обязательно, flac'а достаточно.

[16:33:29] d34df00d: Hi!
[16:33:53] d34df00d: I get 100% CPU usage on gstreamer 1.4.5 in gst_bus_timed_pop().
[16:34:16] d34df00d: I've found a similar bugreport https://bugzilla.gnome.org/show_bug.cgi?id=645746 , but it is quite old, seems to be fixed and related to 0.10.
[16:34:55] d34df00d: The profile looks like this: http://dump.bitcheese.net/images/udorifi/screenshot.png
[16:35:26] d34df00d: (middle column is aggregated time with calls to subroutines, right column is self time)
[16:36:46] d34df00d: I just do gst_bus_timed_pop() in a loop (guarded by an atomic variable to quite polling on shutdown etc.), and if I sleep for a few milliseconds before the call, the problem goes away for me, but some of my users still experience it, but only some time after starting playback, as opposed to immediate CPU hogging without sleep()ing at all.
[16:46:46] stormer: d34df00d: downgrade glib
[16:50:20] d34df00d: stormer: would you recommend any exact version?
[16:56:24] stormer: d34df00d: I don't remember the number, which one are you running ?
[16:56:52] d34df00d: stormer: 2.42.1. Not sure about the particular user who reports that he still gets it even with msleep().
[16:57:09] stormer: ok, so clearly this is one with the new shiny mutex ;-P
[16:57:20] d34df00d: stormer: worth trying 2.40.2?
[16:57:29] d34df00d: I don't have anything else in my distro anyway :(
[16:57:39] stormer: 2.40.2 should do
[16:58:01] d34df00d: Cool, thanks, will try now.
[16:58:24] stormer: d34df00d: it's not a bug in glib, it's really a bug in gst, but it seems we haven't backported the fix (yet?)
[16:59:24] d34df00d: stormer: is there any commit or patch I could recommend applying to gst codebase?
[16:59:37] stormer: I can find it yes
[16:59:50] d34df00d: I would be grateful, thanks.
[17:00:31] stormer: d34df00d: not sure if sufficient, but this is one of the patches, da7847d1adde088b4d8bcfc76642cf942e735dd3
