Once again, how are we supposed to know how many colors the palette

palette size = packet size - width*height


Nope. You have to take the stride in account as well, not just the width
and height, and it varies in nut, depending on whether you use "-vcodec
copy" or "-vcodec rawvideo".

And you'll have to calculate the stride by subtracting the palette size
from the packet size, then divide by the height.

Nope, pixels outside of width x height are ignored.

I need the stride for the alignment to 16 bytes. It's not done for fun.
