uau a703241aa9 Update OSD contents only after the correct values for the frame are known.
The most visible inaccuracy caused by the previous update location was
that the OSD always showed position 0 after seeking with demux_mkv.
Split frame decoding and filtering because with -correct-pts the pts
value that should be displayed for the frame is only known after
decoding but is needed before filtering (during which the OSD is drawn).
