I would like you to focus on version 5 that I've both mailed to you and
posted here.

And why did you omit the 8 bpp changes for AVI? That's what this
patch (or version 5 rather) is about.
put bluntly, because iam not convinced that this is valid in AVI
IIUC you created a avi file with a palette and a blue entry and 1bpp
and then modified ffmpeg to display that with blue.
ok
but
is that correct, does microsofts player display that with blue too?
does the AVI spec say that 1bpp has a palette?
do unmodified avi files exist out in the wild that have 1bpp palettes?
if 1bpp in AVI is per spec and MS reference supposed to have a palette
then we should too and iam happy with the change otherwise we should
keep mono for avi
Microsoft's player doesn't even play raw 1-bit video for some reason,
but that's not our problem, is it? All the documentation on Microsoft's
site on 1-bit video tells us that it's palettized and not simply black &
white. 1, 4, and 8 bit modes, all of them use the palette, if any,
following the BITMAPINFOHEAER. 2-bit mode isn't even official, but still
exists in FFmpeg.
