in the past, postprocessing was done in the codec and was calculated into
decoding time. now it's handled by filter layer, and calculated into vo time
and yes, it may lower decoding time, by allowing direct rendering between
postproc filter and decoder, so some of processing moves out from decoder.
-dr only switch on/off direct rendering to -vo driver, but dr between
filters is always enabled. and it's cool.
i said - pp will be even better and faster than before...
you can apply pp more than once, you can apply pp for every codecs etc.
and it's faster as it increases the probability of dr-ing.
wo/pp: codec --copy--> vram
w/pp: codec --export--> pp --dr--> vram
