To do that type of thing I have a simple program that can
generate any color (-Y, -U, -V), any dimension, and allows setting
the aspect, interlace, rate tags. Oh, can also genereate 4:1:1 output
(NTSC's DV colorspace).
It started out as a simple generate black frames (hence the name
y4mblack ;)) but was added to over time. If others would find
something like that useful I could add it to the mjpegtools
package.
