Description Stuart Langridge 2007-10-13 14:15:16 UTC 
Totem was segfaulting on playing a particular BBC realplayer stream. Invoking a simple playbin also segfaults:

aquarius@wesley:~$ gst-launch-0.10 playbin uri=rtsp://212.58.234.120/nfs01/BBC_Radio_Times/encodedfiles/s10e01_newsweb1_16x9_nb.rm?provider=BBC_Radio_Times
Setting pipeline to PAUSED ...

Seems to play perfectly with CVS everything. This is using rmdemux, realvideodec, ffdec_cook.

Can you run in gdb to get a better stack trace?

Doesn't seem very useful, because I don't have debugging symbols (and I'm not sure I'm doing this right):

0xffffe410 in __kernel_vsyscall ()
(gdb) bt

Just to be sure, you need to run gdb against gst-launch-0.10 not gst-launch (contrary to what the info text from the first post says). Something like this should work:

 $ gdb --args gst-launch-0.10 playbin
uri=rtsp://212.58.234.120/nfs01/BBC_Radio_Times/encodedfiles/s10e01_newsweb1_16x9_nb.rm?provider=BBC_Radio_Times
 Welcome to gdb blablabla
 (gdb) run
 ... wait for crash ...
 (gdb) thread apply all bt
 ... paste result from here ...
 (gdb) kill
 (gdb) quit
