* hevc: remove HEVCContext usage from hevc_psAnton Khirnov2015-07-12
| | | | | | Factor out the parameter sets into a separate struct and use it instead. This will allow us to reuse this code in the parser.
* hevc: Use generic av_clip function, not C implementationPeter Meerwald2015-02-13
| | | | | | | | | hevc seems to be the only place where the C implementation of the av_clip function is explicitly selected, precluding platform-specific optimizations Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* hevc_filter: avoid excessive calls to ff_hevc_get_ref_list()Anton Khirnov2014-08-09
| | | | | | | | 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()
* hevc_filter: move some conditions out of loopsAnton Khirnov2014-08-09

* hevc: deobfuscate slice/tile boundary handling for DBFAnton Khirnov2014-08-09
| | | | | Use named constants instead of magic numbers, avoid using variables with inverse meaning from what their name implies.
* hevc_filter: drop more redundant checksAnton Khirnov2014-08-09
| | | | The if() around those loops ensures this condition is always false.
* hevc_filter: drop redundant checksAnton Khirnov2014-08-09
| | | | | ff_hevc_deblocking_boundary_strengths() is never called if the deblocking filter is disabled for the slice.
* hevcdsp: remove an unneeded variable in the loop filterAnton Khirnov2014-07-26
| | | | beta0 and beta1 will always be the same
* hevc: Do not right shift a negative value in get_pcmLuca Barbato2014-02-23

* hevc: Drop unnecessary shifts in deblocking_filter_CTBLuca Barbato2014-02-23
| | | | beta_offset is pre-multiplied by 2.
* hevc: Consider first quantization group any reference to 0, 0Luca Barbato2014-02-01
