No, you misunderstood what I wanted to express. 
4:2:2 is not outdated, it's just not a something that normal consumer use, which is why it's not in the 'Main' profile of H.264 (and H.265 and ...).
H.264 4:2:2 does not necessarily rely on hardware decoding.
There simply is no hardware decoder for it.
H.264 4:2:2 requires 'High 422' or 'High 444'. (https://en.wikipedia.org/wiki/Advanced_V...r_profiles)
Simple decoders often either:
a. only support (at most) normal 'High' profile (so only 4:2:0)
b. try to send the stream to a hardware H.264 decoder (in case it's present on the system)
Since there is (afaik) no hardware decoder for H.264 4:2:2, the second approach is not usable or will fail.
This brings you back to software decoding and like I said simple decoders simple don't support 4:2:2 and 'High 4:2:2'.
Side node: Any player based on libav&co should work.
