You'll probably need to export it to raw YUV or RGB (depending on the
input color space) and inspect the least significant bits. This might
be easier with a small libav* program than ffmpeg. My first shot would
be trying to understand the raw output formats, and to parse them with
a pipe to a perl one-liner using unpack(). ;-)
