Seeking with h.264 stream (BBC HD) segfaults

Description

I am using changeset [14800] which has the new ffmpeg sync, and am unable to seek within the program. When I do seek the frontend segfaults.

Also on a side note, multithreading for h.264 does not seem to be working also. Both cores aren't utilised and it causes skipping (CPU: ~100%, CPU2: ~15%). But when I use mplayer to play the exact stream directly (with --lavcopts threads=2), the stream plays perfectly with both cores being utilised (CPU1: ~85%, CPU2: ~85%)

The seeking is a know problem in libavcodec. look at issue 189 in the ffmpeg bugtracker.

Multithreaded decoding is not enabled for playback.
