Weirdo vdub bug

test_file.avi 1116KB HUFFYUV2.1.1 5frames (K)

Open file

Video->Direct stream copy

File->Save segmented AVI...

Limit number of video frames per segment to 1 frames

Save

test_file_dsc1.00.avi 228KB HUFFYUV2.1.1 1frame (K)
test_file_dsc1.01.avi 450KB HUFFYUV2.1.1 2frames (K)
test_file_dsc1.02.avi 454KB HUFFYUV2.1.1 2frames (K)
test_file_dsc1.03.avi 10KB HUFFYUV2.1.1 0frame (uh... no Key or delta frames... vdub can open this...)

If I limit the range to 4 frames and again segment to 1 frame avi's


test_file_dsc2.00.avi 228KB HUFFYUV2.1.1 1frame (K)
test_file_dsc2.01.avi 450KB HUFFYUV2.1.1 2frames (K)
test_file_dsc2.02.avi 232KB HUFFYUV2.1.1 1frame (K)

I know I tested this on the 1.4.x series as well with similar results
Only difference is that test_file_dsc1.03.avi was not made in 1.4.x that I can remember.

Source and resulting files can be found here:
test_files

This is tested on Windows 2000SP3, Athlon XP 1900+

While playing around some more with this, I found that you can make 0 frame avi's.
Just load any avi, select all frames and delete, then save.

If there is any use at all for 0frame avi's I guess it's ok, but... should 0frame avis really be possible to save?
