I also tried the build.py from http://code.google.com/p/ossbuild/source/browse/trunk#trunk%2FMain%2FGStreamer%2FMacOSX%2FMacPorts But it did not seem to make any difference...

Any more information please do let me know

Thanks,

Nick

Nick,
This seems similar to #28766 but with a more accurate description and a more direct way to reproduce the error.
You seem much better-equipped to troubleshoot this problem than I am - I maintain gstreamer-related ports out of my interest in ensuring quod libet has a functional and up-to-date backend.
Where would you suggest we start looking for the source of this error?

Good Morning Ryan,

I am new to the Mac and Mac port world. I would start by upgrading the gst-plugins-good to 0.10.28 - I would try this my self but I do not know how to build gstreamer on the Mac - when I run make I get all kind of errors :(

It is a very odd crash and does not give much information to point to what it could be causing it...

Cheers,

Nick

I can confirm this bug. Gstreamer does not play anything: mp3 or wav.

I have the latest versions installed:

This problem seems to be due to an issue known upstream. Originally reported against GStreamer (https://bugzilla.gnome.org/show_bug.cgi?id=628415), it now looks like a problem with Orc (https://bugs.freedesktop.org/show_bug.cgi?id=33836).

The problem can be avoided by using the ORC_CODE environment variable, e.g., ORC_CODE=backup gst-launch playbin uri=...

Perhaps upgrading the MacPorts Orc package will fix this issue. Otherwise, we could compile the GStreamer packages without Orc support.

comment:6 Changed 14 years ago by rmstonecipher@…

Mike,
Thanks for the tip.
Orc was upgraded in r78126.
Quod Libet now plays music without segfaults.

Everyone,
Please upgrade orc then chime in if your gstreamer-based application(s) of choice still exhibit(s) the misbehavior described in this ticket.
I will close this ticket as fixed in roughly one week unless one or more of you give me reason to believe the issue remains unresolved.

Cheers,
Ryan Stonecipher
