Problem was not with the h264/mp3 videos, the files attached had broken frames and hence it wasnt able to decode. I have sent the patch to this problem to the ffmpeg-devel. The problem was with the max_analyse_duration.

I think a reasonable fix consists into telling the user what to do in this case:

lavf/utils: suggest what to do in case of missing codec information
In particular, fix trac issue #218.
Also I couldn't find your patch on ffmpeg-devel (can you provide a link/thread name?).
Feel free to reopen the ticket if you think there is a better solution.
