Hmm, using negative height didn't seem to affect the playback in VLC, WMP nor
VirtualDub. I.e. it did not flip the video, which would have been desirable. It
does cause gstreamer to spit out an error when trying to play the file, though.

There are however many fields in the AVI header which contain the height - I
tried the most obvious combinations negative/positive values, but not all. I
don't know the format well enough to comment on whether the negative height
should be allowed and how it should behave.

I think that when producing AVI files, it is best to use positive height and
reverse the scanlines manually (like the patch does). This ensures the best
compatibility across programs.
