I have tried on mpeg-ts streams from DVB-t broadcasts.
It works with lavf demuxer, not with standard demuxer.

Though with my "sync audio and video after seek"-patch gives better
result with standard demuxer and faad due to seek then ends up with
audio in front of video. May patch will then skip a few video frames to
match audio resulting in half decoded frames being skipped. With lavf
demuxer and ffmpeg audio and video is more in sync after a seek and you
see the incomplete frames which is less nice.
