[vlc] VLC memory leaks?

[Viktor Kompaneyets]

Hi All!

It hurt me hard - but when I use VLC after 20+ hours of streaming, the VLC
process eats all of memory and stops working.

VLC version 0.8.4-test1 Janus
Compiled by tipok at spooler.wnet.ua
Compiler: gcc version 3.3.5 (Debian 1:3.3.5-13)
Based upon svn changeset [12832]

I can't run it under any debuger - because the leak exposes himself only on
heavy-load (I stream 4 transcoded MPEG2 sources in WMV2+MP3 format  with
asfh mux)

As of DVB nature all the source streams are not error-free. The error
cancellation  within VLC shows a lot of errors within -vvv output:

And so on...

Are they ffmpeg-based errors? Who is responsible on correct memory release
after errors - ffmpeg or VLC?
