Just as a parenthesis, regardless of whether this patch is applied or
not, the only way to create a "spec" compliant 1 bpp raw file from a 1
bpp raw AVI or QuickTime file is to use nut as output, like "ffmpeg -i
1bpp.avi -vcodec rawvideo [-pix_fmt monow] 1bpp.nut". Both AVI and
QuickTime will have the wrong stride in the output files. AVI should use
a 4-byte aligned, and QuickTime a 2-byte aligned stride, but it will
currently be the same as in nut, i.e. the minimum possible one.
