Only the (insignificant) timestamps are different.

This "fixes" it:

diff --git a/libavformat/utils.c b/libavformat/utils.c

I have no idea what this does, and it happens in
avformat_find_stream_info(), which is satan.

Would it be ok to send a new patch with the timestamps changed in the
ref file?
