video crashes due to vdpau decoders

StacktraceTop:realloc () from /lib/libc.so.6

looks like another libavcodec issue.

Just tested by downloading that file15 and opened with totem, totem crashed with (core dumbed)

dmesg shows:

[18992.088484] totem-gstreamer[10410]: segfault at 7478656c ip 00007f4a909cfcfa sp 00007f4a750f2a90 error 4 in libc-2.9.so[7f4a90953000+168000]

do you still get the issue using the current version? the video example works correctly there

There is a similar error on http://bugzilla.gnome.org/show_bug.cgi?id=573400

could you try if the gstreamer0.10-ffmpeg 0.10.6.2 update in jaunty fixes your issue?

Tested on both Firefox-3.1 and the default, firefox-3.0.7
This is before restart (uptime
 16:36:53 up 5 days, 1:16, 3 users, load average: 0.08, 0.23, 0.18)
Dmesg is showing:
[436019.412599] totem-plugin-vi[9217] general protection ip:7f522d6fa141 sp:7f52276a2b40 error:0 in libavcodec.so.52.11.0[7f522d4d9000+49a000]

But to my understanding restart isn't needed to these updates to take effect.
Reporting here after restart.

Forgot to say, that the update still hasn't fix my issue.
Trying to view that sample 15 on URL in guestion, it just hangs, doesn't crash the browser.
Sample just loads and finally it's stopped. (file doesn't play)

could you run "dpkg -l | grep gst", do you get the issue if you download the file locally and play it there?

Just tested after restart, Neither browser works, just hangs.
Downloaded both samples, 14 & 15
14 plays without any issues.
15 crashed totem

does ffplay plays it correctly for you?

"could not find caps for codec (wmv3_vdpau), unknown type" is a gstreamer0.10-ffmpeg issue fixed in git and will be fixed later this week in jaunty

I tried compiling the ffmpeg libraries from source in Jaunty, but it still crashes on me using an Acer Netbook powered by the Intel(R) Atom(TM) CPU N270.

the bug has not been fixed in jaunty but only in the upstream svn so it's normal rebuild the jaunty version makes no difference

ok, I can get the issue after installing libavcodec-unstripped-52 instead of libavcodec52, does anybody else use the unstripped version?

ok, I can confirm the crash at end of the video examples on launchpad with the unstripped version and the upstream change fixes the issue

This bug was fixed in the package gstreamer0.10-ffmpeg - 0.10.6.2-1ubuntu1

---------------
gstreamer0.10-ffmpeg (0.10.6.2-1ubuntu1) jaunty; urgency=low

  * debian/patches/06_disable_vdpau_decoder.patch:
    - git change to disable the vdpau decoder that should fix lot of crashers
      (lp: #330165, #332860)

 -- Sebastien Bacher <email address hidden> Thu, 12 Mar 2009 11:40:47 +0100

Fix has cleared my issues.

But next, if vdpau_decoder is disabled, ffmpeg/gstreamer devs are trying to find a way to enable for it to work?

Yes! The bug is fixed :)

Thank you very much!

The totem-mozilla package from the beta of Jaunty still installs a broken symlink, /usr/lib/mozilla/plugins/libtotem-basic-plugin.so, for anyone interested.
