i think no we should not add such dependancy in the example, there are
so many packages around alraedy that create their own intermingled micro
universes. I hope ffmpeg will not degenerate into such a thing, lets
leave all the parts be useable on their own ...

can i see the code?

btw, the format we want as output is a raw format with header createable
with a single printf() for a swscale example
