Anton Khirnov	7acdd3a127	hevc_filter: avoid excessive calls to ff_hevc_get_ref_list() ... 1) each of the loops run within a single CTB, so the relevant reference list is constant 2) when that CTB is, or lies on the same slice as, the current one, we can use a simple access instead of a relatively expensive call to ff_hevc_get_ref_list()	2014-08-09 16:15:51 +00:00

Anton Khirnov	70211539a3	hevc: deobfuscate slice/tile boundary handling for DBF ... Use named constants instead of magic numbers, avoid using variables with inverse meaning from what their name implies.	2014-08-09 16:13:48 +00:00
Anton Khirnov	5501971578	hevc_filter: drop more redundant checks ... The if() around those loops ensures this condition is always false.	2014-08-09 16:13:37 +00:00
Anton Khirnov	65b8b6c476	hevc_filter: drop redundant checks ... ff_hevc_deblocking_boundary_strengths() is never called if the deblocking filter is disabled for the slice.	2014-08-09 16:13:24 +00:00
Anton Khirnov	73bb8f61d4	hevcdsp: remove an unneeded variable in the loop filter ... beta0 and beta1 will always be the same	2014-07-26 15:00:11 +00:00

Luca Barbato	50c988aa6d	hevc: Drop unnecessary shifts in deblocking_filter_CTB ... beta_offset is pre-multiplied by 2.	2014-02-23 14:34:34 +01:00
