Bug 256250 – media-video/gpac-0.4.4-r1 MP4Box "double free or corruption" crash with podencoder script

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description m.misamore 2009-01-24 22:29:18 UTC]

New bug in gpac as of 0.4.4-r1 (previous versions of gpac from portage were working fine) when encoding flv files with MP4Box for a 5G Video Ipod. Trying to encode results in a big messy crash (output given below). 

Supposedly this is fixed in gpac CVS: see https://bugs.launchpad.net/ubuntu/+source/gpac/+bug/135071 but I haven't been able to successfully build the source from CVS, for reasons that I didn't want to take hours to decipher. The ebuild for 0.4.4-r1 obviously built fine, however.


Reproducible: Always

Steps to Reproduce:
1. Get the podencoder script from http://podencoder.googlecode.com/svn/trunk/podencoder
2. Set the execute bit and run ./podencoder test.flv  where test.flv is your favorite flv file.
3. Watch the fireworks.
Actual Results:  
(Crash log attached)


Expected Results:  
Was expecting the podencoder script to successfully encode the video into an mp4.

I've just attached the output of an attempt to do something similar with an mpg file.

[Comment 4 Tony Vroon (RETIRED) 2009-01-26 15:10:22 UTC]

Individual program crash with no detrimental effect on system stability, downgrading severity to 'normal'.

[Comment 5 Samuli Suominen (RETIRED) 2009-12-19 11:20:49 UTC]

Then it's supposedly fixed in 0.4.5 (-r1). 

If you can still reproduce, reopen.
