Replying to richardpl:
No, that is bad idea. You need to control them manually. There is setparams filter now.
Why it's a bad idea in case this values set in contaner of input files? The bad idea is the current behaviour – implicitly, despite everything, decode using Rec.601.

In case bt709 is set it will decode as bt709. Ffplay does not support bt2020 and some other stuff but there is a workaround for ffplay.
