Mark Thompson	3daaa44173	hevc: Add names for reserved NAL unit types While not yet used, these NAL units do already have some defined semantics and are referred to elsewhere.	8 years ago
Anton Khirnov	0bfdcce4d4	hevc: move the SliceType enum to hevc.h Those values are decoder-independent and are also use by the VA-API encoder.	8 years ago
Anton Khirnov	f6e2f8a9ff	hevcdec: move parameter set parsing into a separate header This code is independent from the decoder, so it makes more sense for it to to have its own header.	8 years ago
Anton Khirnov	c359d624d3	hevcdec: move decoder-independent declarations into a separate header This way they can be reused by other code without including the whole decoder-specific hevcdec.h Also, add the HEVC_ prefix to them, since similarly named values exist for H.264 as well and are sometimes used in the same code.	8 years ago
Anton Khirnov	4abe3b049d	hevc: rename hevc.[ch] to hevcdec.[ch] This is more consistent with the rest of libav and frees up the hevc.h name for decoder-independent shared declarations.	8 years ago
Anton Khirnov	fa936a307f	hevc_parse: rename into h2645_parse This code will be shared with h264.	9 years ago
Philip Langdale	8958c5c64d	hevc: Track long and short term RPS size for VDPAU 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.

Hendrik Leppkes	8c399bd5ce	dxva2_hevc: properly signal the num_delta_pocs from the SPS RPS 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.

Anton Khirnov	e7078e842d	hevcdsp: add x86 SIMD for MC	9 years ago
Anton Khirnov	d82e1adc20	hevc: move splitting the packet into NALUs into a separate function This function is independent of the decoding context, so we'll be able to use it in the parser.	9 years ago
Anton Khirnov	ae05b48655	hevc: eliminate the second call to hls_nal_unit() 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.	9 years ago
Anton Khirnov	b11acd5732	hevc: remove HEVCContext usage from hevc_ps Factor out the parameter sets into a separate struct and use it instead. This will allow us to reuse this code in the parser.	9 years ago
Anton Khirnov	66acb76bb0	lavc: add Intel libmfx-based HEVC encoder	10 years ago
Anton Khirnov	69ab9f53f9	hevc: split bitstream unescaping to a separate file It will be useful in the QSV HEVC encoder.	10 years ago
Anton Khirnov	fd124d8357	hevc_ps: split the code for parsing the SPS and exporting it into the context This will be useful in the later commits, where we want to parse an SPS without having a whole decoding context.	10 years ago
