tried also with totem-xine and got a different bug: audio gets out of sinc, but video playback is ok,

xine's saying the MPEG header is damaged, but I'll pass this to the GStreamer people to see if they can do anything to improve GStreamer's behaviour in this situation.

Could you provide a more detailed GStreamer log, with the following command?

GST_DEBUG_NO_COLOR=1 GST_DEBUG=*:5 totem 2> totem.log

Would you also be able to provide a movie file which displays this behaviour, or at least the first 50KiB of one (use the following command)?

head -c 50kB file.mpg > header.mpg

GStreamer plugin versions (from Launchpad report):
gstreamer0.10-plugins-base 0.10.22-4
gstreamer0.10-plugins-good 0.10.14-1

Note also that there's a more detailed log from xine available on the Launchpad report: https://bugs.launchpad.net/ubuntu/+source/totem/+bug/353444/comments/3
Comment 5 Fernando Miguel 2009-04-05 18:32:38 UTC
i'm having trouble reproducing this now.
I got w64codecs upgrade, not sure if that changed something
I'm attaching 2 new logs with the test solicited
Comment 6 Fernando Miguel 2009-04-05 18:40:04 UTC
ok I take it back... it generated a 270MiBs and one 720MiBs logs!!! those are not suitable to upload via 3G eheh
Do you have any idea why this logs are so big?
i ran: GST_DEBUG_NO_COLOR=1 GST_DEBUG=*:5 totem 2> totem.log
Comment 7 Sebastian Dröge (slomo) 2011-05-20 06:07:51 UTC
Can you make the file available? And is this still happening with the latest releases?

It's normal that the logs are that large, you could compress them with bzip2. The logs are usually good to compress
