The mplayer2 process uses 100% CPU when paused. Happens with any video. At least for me. Not for other people it seems.

A gdb backtrace of the place where it loops would be nice.
I was trying to produce one, but - I could not reproduce the problem. Now I found out that it only happens when I open a video clip from Dolphin. It is set to execute 'mplayer2 %U', nothing special. Or I can choose 'open with' and then enter mplayer2. But when I run this from the command line, the CPU does not go up when pausing. Seems to be another weird KDE effect. I'd like to help debug this, but I have no idea how. I know how to build mplayer2 with debug information, and I probably could manage to make gdb run it and produce a stack trace, but can this also be done when starting from Dolphin? Oh, and it does not happen when I do the same as another user with an unconfigured KDE. So I guess I am the only one in the world facing this. Should we close the bug, and maybe I should report this on bugs.kde.org?
Hi, same bug here, using XFCE on stable Gentoo (amd64). Running mplayer2 from terminal seems to solve the issue too, but I have the issue when I start a movie from Thunar. Anyway, I've found this : http://devel.mplayer2.org/ticket/146 It seems that some upstream guys found a patch that correct the issue; maybe someone should test-it ?
Thanks ojio, nice find! Confirmed, there is no problem any longer with media-video/mplayer2-9999. I have another problem with both mplayer and mplayer2, videos stutter sometimes, expecially when I create I/O. This also only happens when started from Dolphin (did not test other file managers though), from the command line it is okay, or when I configure Dolphin to open mplayer in a terminal. This fix for mplayer2 did not help, must be some other problem I guess. Just mentioning, in case there is indeed a connection to this bug.
Upstream bug #146 is fixed now. Snapshot with http://git.mplayer2.org/mplayer2/commit/?id=b93ed278362185ff980e0ce8f4ab3029f8fe395f is in portage.
