Package: libavcodec53
Version: 6:0.8.4-1
Severity: important
Tags: patch
Hi,
In some situations, transcoding a wmav2 file can lead to a infinite loop
(which is leaking a lot of memory).
A patch has been merged in ffmpeg codebase, but this is still present in
libav. (3cb64e327a9861f2c8fff0b3850fcd5d14acdbe3 on ffmpeg git
repository).
Please find attached the backport of the patch.
Cheers
Laurent Bigonville

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=695593 I guess this
bug could be closed
15:25 <bigon> (yes I'm quite lagging, but I'm starting again to use
libav for transcoding)
