Hendrik Leppkes	6eb1b40ad8	hevc: fix size condition in ptl parsing When only one sublayer is present, no information is coded. Only when at least two are present, all 8 sublayers are written. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago

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.

Hendrik Leppkes	f85cc3bf12	hevc: set profile based on the profile compatibility flags if needed This fixes retrieving a valid profile for many of the FATE conformance samples, allowing them to be properly decoded by the HWAccel after adding a profile check.	9 years ago

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>	10 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.	10 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.	10 years ago
