* hevc_parse: rename into h2645_parseAnton Khirnov2016-03-28
| | | | This code will be shared with h264.
* hevc: Track long and short term RPS size for VDPAUPhilip Langdale2016-02-13
| | | | | | | | | | | | | | | | Today, we track the short term RPS size for DXVA, but only if the SliceHeader RPS is being used. Otherwise it's left uninitialized. NVIDIA's VDPAU implementation requires that the size be accurately tracked even if an SPS RPS is being used. In this case, it's really counting the size of the RPS idx information, but you end up with mangled output if the value is not accurate. VDPAU also needs the size of the long term RPS.

* dxva2_hevc: properly signal the num_delta_pocs from the SPS RPSHendrik Leppkes2016-02-13
| | | | | | | | | ucNumDeltaPocsOfRefRpsIdx needs to contain the flat value from the SPS RPS, and not the final computed value from the slice header RPS, as this calculation is done internally by the driver again.

* hevcdsp: add x86 SIMD for MCAnton Khirnov2015-12-05

* hevc: move splitting the packet into NALUs into a separate functionAnton Khirnov2015-07-12
| | | | | This function is independent of the decoding context, so we'll be able to use it in the parser.
* hevc: eliminate the second call to hls_nal_unit()Anton Khirnov2015-07-12
| | | | | | | Also, make hls_nal_unit() work only on the provided NAL unit, without requiring a whole decoding context. This will allow splitting this code for reuse by the parser.
* 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.
* lavc: add Intel libmfx-based HEVC encoderAnton Khirnov2015-07-08

* hevc: split bitstream unescaping to a separate fileAnton Khirnov2015-07-08
| | | | It will be useful in the QSV HEVC encoder.
* hevc_ps: split the code for parsing the SPS and exporting it into the contextAnton Khirnov2015-07-08
| | | | | This will be useful in the later commits, where we want to parse an SPS without having a whole decoding context.

* 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: eliminate the last element from TransformTreeAnton Khirnov2014-07-28
| | | | Replace it by passing an additional parameter to transform_unit()
* hevc: eliminate unnecessary cbf_c{b,r} arraysAnton Khirnov2014-07-28
| | | | | They are replaced by passing additional parameters to the transform functions.

| | | | It does not need to be preserved.
* hevc: eliminate an unnecessary arrayAnton Khirnov2014-07-28
