Hendrik Leppkes	5d324dae11	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.

Luca Barbato	8e373fe048	hevc: Factor out the pixel format mapping from the sps parser The function will grow larger as more formats are supported. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago
Anton Khirnov	b9f76d19d8	hevc_ps: make sure failing to decode an SPS always returns an error Some of the goto err clauses do not set the error code. It seems better to fall back on INVALIDDATA instead of adding it everywhere explicitly.	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	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.	9 years ago

Christophe Gisquet	0625a38066	hevc_ps: check overflow and test alternate syntax Some streams were found to have what appeared to be truncated SPS. Their syntax seem to be valid at least until the end of the VUI, so try that syntax if the parsing would overflow the SPS in the conforming syntax. Fixes ticket #3872.
