Mark Thompson	1329c08ad6	hevc: Validate the number of long term reference pictures This would overflow if the stream contained a value greater than the maximum allowed by the standard (32).	8 years ago
Mark Thompson	b88da98b34	hevc: Improve stream constraint values in common header Add comments to describe the sources of the constraint values expressed here, and add some more related values which will be used in following patches. Fix the incorrect values for SPS and PPS count (they are not the same as those used for H.264), and remove HEVC_MAX_CU_SIZE because it is not used anywhere.	8 years ago
Diego Biurrun	d4c2103bd3	golomb: Convert to the new bitstream reader	8 years ago
Anton Khirnov	a02ae1c683	hevcdec: export cropping information instead of handling it internally	8 years ago
Vittorio Giovara	ff9db5cfd1	lavc: Use a stricter check for the color properties values Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	8 years ago
Diego Biurrun	67deba8a41	Use avpriv_report_missing_feature() where appropriate	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	150c896a9e	hevcdec: split ff_hevc_diag_scan* declarations into a separate header This will be useful in the following commits.	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
Hendrik Leppkes	1ecb63cd1c	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. Signed-off-by: Anton Khirnov <anton@khirnov.net>	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. Sample-Id: http://trailers.divx.com/hevc/Sintel_4k_27qp_24fps_1aud_9subs.mkvi Signed-off-by: Rémi Denis-Courmont <remi@remlab.net>	9 years ago
Vittorio Giovara	7c6eb0a1b7	lavc: AV-prefix all codec flags Convert doxygen to multiline and express bitfields more simply. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Luca Barbato	c88c5eef53	hevc: Split the struct setup from the pps parsing	10 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>	10 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
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
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
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
Anton Khirnov	17e9d52c8c	hevc_ps: remove a write-only variable	11 years ago
Gildas Cocherel	a0e1c3517a	hevc: remove unused array min_cb_addr_zs Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Kieran Kunhya	9b60d91979	hevc: Allow out of bound values for num_reorder_pics This fixes decoding for a sample that cannot be shared Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago

Luca Barbato	175e506332	hevc: Mention the missing SPS in the error message	11 years ago
Luca Barbato	838740e642	hevc: Prevent some integer overflows get_ue_golomb_long() returns an unsigned. Sample-Id: 00001541-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	11 years ago
Luca Barbato	b37e796082	hevc: Use uint64 to check for tile dimensions And use unsigned datatypes. Otherwise it would overflow. Sample-Id: 00001315-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	11 years ago
Michael Niedermayer	a7a07cc98a	hevc: check that VPS referenced from SPS exists This matches how its done for SPS/PPS. Fixes null pointer dereference. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago

Guillaume Martres	78d0b7f36e	hevc: warn when an unknown profile is used Bitstreams conforming to the spec should not use profiles not defined in it. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago

Guillaume Martres	67bbaed5c4	hevc: don't check for errors in PTL code According to the spec, the value of XXX_reserved_zero_44bits should be ignored, so don't report an error when it's not zero. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
