Comment (by cehoyos):

 Replying to [ticket:8455 john123]:

 > In the head of github source there is a AV_PIX_FMT_YUVJ420P defined, but
 it's not allowed in av1_pix_fmts etc. Is this intentional? It makes AV1
 rather damaging for a yuvj420p input that has a lot of very dark and very
 bright pixels.

 That makes no sense.

 Why don't you provide sample input and command line including the
 complete, uncut console output to give us a chance to understand your
 issue?
