for specific patterns in the intra signal in the first pass stats

scene cuts that were previously being misssed.

Tested on two clips where the existing code was struggling to

further tweaking.

previously missed, mainly in darker scenes. There were a few

explosions but these were cases where there was little
difference between inter and intra coding.

Paul Wilkins [Thu, 28 Feb 2019 14:10:12 +0000 (14:10 +0000)]
Change to mode early breakout rules for FILM mode.

The biggest offender in terms of preventing retention of film
grain in high rate film content is the use of DC-PRED mode.
Some of the directional modes whilst not strictly preserving
grain do better at at least preserving some texture.

This change blocks the early breakout of the rd loop based
on the reference frame giving the best result so far. In practice,
unless DC-PRED was chosen as the best mode so far, the other
directional intra modes would not even be considered.

As the film grain mode also tends to bias against DC-PRED (or
intra in general) this was pretty much blocking all use of directional
intra modes.

The patch also allows for a broader spectrum of DC modes at the
16x16 transform level than previously.
