Michael Niedermayer	f8e4d37983	avcodec/hevc_ps: Also print depth in failure path of map_pixel_format() Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Luca Barbato	c88c5eef53	hevc: Split the struct setup from the pps parsing	9 years ago
Luca Barbato	32c8d89c03	hevc: Print the non-supported chroma_format_idc And drop the spurious newline. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	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>	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
Michael Niedermayer	15893adbdb	avcodec/hevc_ps: Remove gotos from ff_hevc_parse_sps() They are currently unnecessary Found-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	9 years ago
Michael Niedermayer	1dacf26964	avcodec/hevc_ps: Do not return success on failures in ff_hevc_parse_sps() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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

Anton Khirnov	df528b11ac	hevc: make sure no dangling pointers remain around on VPS/SPS change	10 years ago
Anton Khirnov	ce0bc09ee2	hevc: do not change the VPS if its contents are the same This is the same as is done for SPS.	10 years ago
Michael Niedermayer	06c70d4537	avcodec/hevc_ps: Check cropping parameters more correctly Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Anton Khirnov	5127c00b97	hevc: zero the correct variables on invalid crop parameters It's the output_window that is applied to the output frame, not pic_conf_win	10 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.
