[Bug 53539] Totem-xine hangs when seeking fast in AVI video with subtitles enabled

[Ripper]

Public bug reported:

Binary package hint: totem-xine

Playing AVI video (divx/xvid) with subtitles enabled (srt, windows-1250
encoding) and seeking very fast with cursor keys results in Totem gui
being totally unresponsive. Killing application is the only way.

Problem occurs only when subtitles are enabled. Does not occur when
seeking via progress bar (you can't seek fast), and mostly does not
occur when you press cursor keys (left/right) only once. When you press
cursor keys a few times in a rapid fashion (or hold it for a while),
after few seeks the GUI hangs and is unresponsive to mouse or keys.
Video and sound still plays. Only way is to kill Totem.

In my case, I tried it on at least 10 different videos, and on two
computers (both Ubuntu 6.06, one fglrx and one radeon video driver).
Happens on 100%, every time!

Using Ubuntu 6.06, Totem 1.4.1 with xine-lib 1.1.1.

Happens also in Kaffeine. So I thought it's a xine bug, but xine-ui is working fine. I think it is because xine-ui does not seek "ahead". When you seek in xine-ui, it takes some time, and you can seek again only after previous seek
has completed (so it is quite slow). In Totem, you can seek more rapidly (and therefore faster), but when subtitles enabled, this bug occurs. Makes Totem (and Kaffeine) totally unusable for watching movies with subtitles, hangs every while.

I have reported this bug also on official Totem bugtracker (Gnome bugzilla):
http://bugzilla.gnome.org/show_bug.cgi?id=348110
but I could not provide backtrace, so the bug was put away as NEEDINFO. To provide backtrace I needed debug version of xinelib, which is not available in Ubuntu repositories. I was advised to file a bug against my distribution (Ubuntu). I hope it will get further in here, it is really serious bug, it blocks using Totem when displaying movie with subtitles (every movie in my case).
