VLC crashes playing h264 video

Crashes on Mac OS (1.1.{11,12}) and Win32 (1.1.11 tested). See attach.

Workaround:

1. build libavcodec.a from ffmpeg's git master HEAD.
2. recompile libavcodec_plugin with it

Sample file which crashes VLC: http://dl.dropbox.com/u/43104344/vlc_crash_example.ts

Try VLC 1.2. To me, that's fixed in the latest contrib.

added Component::Build system: Contribs Status::fixed labels

changed milestone to %2.0.0 bugs

vlc crash_5.ts vlc://quit --rate 100 --no-skip-frames --ffmpeg-skip-frame=-1 --no-audio

Happens with very last ffmpeg master HEAD - ffmpeg version N-35516-ga99dbe0

Is NOT reproducable with

ffmpeg -f mpegts -i crash_5.ts -skip_frame none -vcodec rawvideo -an -f mpegts -y /dev/null

Media file is here: http://dl.dropbox.com/u/43104344/libav_loop/crash_5.ts
