[vlc-devel] Picture freeze bug in libvlc.

[Sergey Radionov]

And more news:
if build against
*contrib-20110823-win32-bin-gcc-4.4.4-runtime-3.17-only.tar.bz2*
(previously I build against
*contrib-20111017-win32-bin-gcc-4.4.4-runtime-3.17-only.tar.bz2*)
problem was not arrive.

So, I think, it is a bug in libavcodec included in last contrib(20111017,
libavcodec v 53.20.1). I'll try build ffmpeg from git, and test it...
