[Ffmpeg-devel] Patch: avi DV seeking

Hi all

I have a large (11GB) DV file in avi that ffplay crashes when seeking
without the attached patch. I must admit, though, that this is a
"blind" fix, in that I don't know if the AVI format+ffmpeg
implementation should guarantee that ast2 should not be null at this
point. All I know is that in my particular DV file, it is null. And
st2->nb_index_entries == 0.

If this is not the correct way to fix the problem, let me know what
other info I could provide to help track down the problem.
