Problems with Wx::MediaCtrl GStreamer wrapper on Kubuntu

[it]

Hi Guys,

I'm having a couple of problems with the Wx::MediaCtrl wrapper of GStreamer
under Kubuntu and Perl.

1) Wx::MediaCtrl crashes at end of file (Kubuntu 9.10 only as it doesn't
occur on Windows - maybe GST is not there anyway - and my colleague didn't
see it on his Debian setup).  I've rebuilt on 2 different Kubuntu machines
with the same result.  I've not tried Lucid.

2) Wx::MediaCtrl wrapper doesn't play a live feed either from a live file
feed, where at the end of the file as it was on open we get the crash above,
or from a webcam URI.

Both problems can be seen in the Wx::Demo package
(http://search.cpan.org/dist/Wx-Demo/) for MediaCtrl for any video (I've
been using .AVI files).

My setup is as follows:

* gstreamer0.10-ffmpeg
* libgstreamer0.10-0
* libgstreamer-perl
* libgstreamer-plugins-base0.10-0
* gstreamer0.10-x
* gstreamer0.10-doc
* gstreamer0.10-plugins-good
* gstreamer0.10-plugins-base
* gstreamer0.10-tools

* libwx-perl-processstream-perl
* libwx-perl-dialog-perl
* libwx-perl
* ffmpeg

* Wx::Perl 0.98
* wx 2.8.10
* Perl 5.10
* Kubuntu 9.10

Any help would be much appreciated.

Have a good weekend.

Regards

Steve

You should probably try 10.10 and/or the GStreamer PPA (which has newer
packages).

Does the crash also occur if you play the file/stream from the command
line like this:

  gst-launch-0.10 playbin2 uri=file:///file/to/foo.bar

?

If yes, maybe you could install the various -dbg packages
(libgstreamer0.10-0-dbg, gstreamer0.10-plugins-base-dbg,
gstreamer0.10-plugins-good-dbg etc.) and then get a stack trace with:

 gdb --args /usr/bin/gst-launch-0.10 playbin2
uri=file:///file/to/foo.bar
 (gdb)run
  ... wait for crash ...
 (gdb) thread all apply bt
  ...
 (gdb) kill

Cheers
 -Tim

Hi Tim-Philipp, Thanks for this.

What does a crash look like?  When it gets to the end of the video the
window closes.  Is that a crash?

Regards

Steve

Only if it prints SEGFAULT or something similar on the terminal. You could also run:

gdb --args gst-launch-0.10 playbin2 uri=file:///file/to/foo.bar

type "run" inside gdb. Once the window closes, gdb would say "Program exited
normally" to indicate everything is fine. If in doubt, post the output your see
on your terminal in the reply here.
