Fix crash on startup for a52 decoder (not that I know *why* this fixes the crash) (1.41 KB, patch)
2009-03-07 23:46 UTC, ogg.k.ogg.k 		none Details | Review

Description ogg.k.ogg.k 2009-03-07 23:45:33 UTC 
Steps to reproduce:
1. Install gst-plugins-ugly
2. Install Thoggen
3. Run Thoggen
4. Encode a DVD with a52 audio


Stack trace:
I don't have one just now, but it's crashing when starting encoding.
I will post one later (I'm encoding currently so don't want to revert
and install the buggy version). OTOH, since it has to be widely used,
I'm not sure why it'd still be crashing (it was almost a year ago).
Maybe I'm just spectacularly unlucky. But this machine was rebuilt,
and still needs the patch, so...

Comment 2 ogg.k.ogg.k 2009-03-08 07:48:18 UTC 
Stack trace follows.
The crash actually happens when Thoggen starts, rather than when
starting encoding. Not sure why it'd crash here, the line seems
quite innocuous.

Core was generated by `./src/thoggen --gst-disable-segtrap'.
Program terminated with signal 11, Segmentation fault.

Comment 3 Thiago Sousa Santos 2010-01-07 22:43:58 UTC 
How do we select the codecs in thoggen?
Comment 4 ogg.k.ogg.k 2010-01-07 22:51:28 UTC 
The A52 codec is automatically selected when the DVD you attempt to read uses that codec.
Comment 5 Sebastian Dröge (slomo) 2010-05-10 10:16:36 UTC 
Is this still reproducible with the latest core release?
Comment 6 ogg.k.ogg.k 2010-05-10 11:33:10 UTC 
It seems to work without the kludge. It's been a while, so I'm not 100% sure I'm doing things the same way I used to, but IIRC I was running Thoggen the straightforward way.
So, call it fixed, thanks.
