JPEG Decode: check values of horizontal and vertical sampling factors (v2)

Sreerenj,

I'm not sure how to make it become generic. Is it really all the video format
(h264, h265, MPEG2, VC1...JPEG) decode is using generic horizontal sampling
factor and vertical sampling factor? Maybe can you explain more a bit? Or send
me the link I can go read it. And come out properly fix.
