[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

Если возможно, попробуй наложить http://cgit.freedesktop.org/gstreamer/gstreamer/commit/?id=da7847d1adde088b4d8bcfc76642cf942e735dd3 на gstreamer.

Можешь не пробовать, я у себя проверил, не помогает.

Актуально с gst 1.8, воспроизвелось через 2 дня использования.

Актуально ли сейчас?

Наверно, нет.
