Bug 118364

I have the same effect on Mandriva 2006, even after upgrading Kaffeine from Cooker.

This is a forwarded bug:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=350224

Package: kaffeine
Version: 0.7.1-1.3+b1

While playing some movies (in example dvix) via kaffeine with xine
engine, the kaffeine sort of hangs after rewinding movie a bit around,
the movie continiue to play, user can move even the window around,
although kaffeine UI do not accept any commends (one can NOT stop movei,
rewind, pause, or even close the program normally - have to kill it)

i reproduced in 0.8.1, i found also 2 related bugs on sf bts:
http://sourceforge.net/tracker/index.php?func=detail&aid=1389188&group_id=86937&atid=581406
http://sourceforge.net/tracker/index.php?func=detail&aid=1210353&group_id=86937&atid=581406

ps: sorry for the 3 comments

I can confirm it, the issue exists in Kaffeine since at least 0.4x releases.

i have the same problem, sometimes, when moving around in the video, kaffeine does not accept input anymore, and subtitles do not appear, but the video still plays back, the problem solves itself when the video is finished

*** This bug has been confirmed by popular vote. ***

Also happens in 0.8.2, ubuntu edgy.

Somebody fix this please! It makes watching movies a real pain! :)

The bug appears to be fixed in 0.8.3. Can somebody confirm?

I can still reproduce it with 0.83, it hangs only with subtitles turned on.
Since 2 reporters mentioned subtitles here, I will mark bug #130905 as a duplicate of this.

*** Bug 130905 has been marked as a duplicate of this bug. ***

which xine-lib version are you using? there was an important bug fix in 1.1.3 with regard to subtitles & seeking ...

I am somewhere among the duplicates -- I experienced the same bug before, but I didn't see it for a looong time. The only crash I see is with embedded Kaffeine, but it is already another report for it.

I still see this bug.
I am using Kubuntu 7.04, which has libxine1 1.1.4-2, kaffeine-xine 0.8.3-0 and Kaffeine 0.8.3-0.

I can reproduce this every time I watch a movie with subtitles and use the seek function.

Actually, now the UI only freezes for a few secondes (~15), then continues to work normally.

a) please update your system -- libxine1 1.1.6, kaffeine 0.8.4 here, maybe that makes a difference (but I doubt it)
b) just for be sure -- by "seek" you mean for example clicking on slider, or pressing left/right?

please run kaffeine in gdb:
type "gdb --args kaffeine --nofork", then "run"
do the necessary steps to reproduce the hang
press ctrl+c
type "thread apply all bt" and attach the output here :-)

and oh - you could try if you get the same behaviour with other xine-lib frontends like xine-ui or gxine ...

I can still reproduce it with xine 1.1.6
It does not matter if I seek using the slider or by using the arrow keys.
gxine has the same problem.
xine-ui does not have the problem.

Okay - so the issue is in xine-lib :)

xine.c:1201 is "pthread_mutex_lock( &stream->demux_lock );" (although I don't know which version you're using I'm pretty sure)

demux.c:285 is "status = stream->demux_plugin->send_chunk(stream->demux_plugin);" - the problem occurs when this call blocks (because demux_lock is held) ...

I don't know the cause why it hangs for you - but kaffeine can't do anything against it ...

But xine-ui works. Isn't that just a normal client to xine-lib?

That is correct.

Probably not :(

> But xine-ui works. Isn't that just a normal client to xine-lib? 
xine-ui seeks in a different thread so it may be harder to reproduce the bug, but sooner or later you'll face it.
 

closing this because the bug is in xine-lib (same behaviour with gxine)

FYI: I found an old bug report for xine about the very same problem, see https://sourceforge.net/tracker/?func=detail&atid=109655&aid=1164531&group_id=9655
