Summary of the bug:
Converting to rawvideo BGR24 occasionally produces AVIs that can not be
loaded by most Windows players. ffmpeg itself seems to be able to load
them without issue though.
How to reproduce:
https://www.dropbox.com/s/2bhlwsnwg5n77b4/damaged_uncompressed.zip?dl=0
damaged_uncompressed_source.avi is the source video.
damaged_uncompressed_out.avi is the output from FFMPEG. This file will
not open in MPC-HC 1.6.7.7114 or Windows Media Player 12.0.9600.17031.
VirtualDub 1.10.4 will open it, but it will not show any video.
damaged_uncompressed_out_vdub.avi is output from opening
damaged_uncompressed_source.avi and saving it as Uncompressed using
VirtualDub. It plays back fine in all of the aforementioned programs.
Using -pix_fmt yuv420p instead does not cause this problem.
Using -vcodec bmp instead will allow VirtualDub to open the video, but it
will be upside-down and have severe artifacts. MPC-HC and WMP will still
not load it.
