Vittorio Giovara	c442190a6b	error_resilience: initialize prev_* variables CC: libav-stable@libav.org Bug-Id: CID 732293 / CID 732294	10 years ago
Michael Niedermayer	20df02680c	avcodec/error_resilience: avoid pointer arithmetic with NULL move the code after the existing NULL check Fixes: signal_sigsegv_844d59_10_signal_sigsegv_a17bb7_366_mpegts_mpeg2video_mp2_dvbsub_topfield.rec Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Diego Biurrun	7cb66ebc0b	error_resilience: Drop asserts from guess_mv() The asserts check struct members that are not referenced in guess_mv() and one of them fails to compile.	10 years ago
Michael Niedermayer	c103c48525	avcodec/error_resilience: make error an local variable where possible This makes the code easier to understand as the scope of the variable is smaller. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	459996325d	avcodec/error_resilience: comment out unused assignment Its not removed as the code which uses this is out-commented too. Found-by: CSA Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Diego Biurrun	2d60444331	dsputil: Split motion estimation compare bits off into their own context	10 years ago
Michael Niedermayer	81d1fcf37d	avcodec: add option to make is_intra_more_likely() from error concealment return "no" Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	36053aeff6	vcodec/error_resilience: use av_malloc_array() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Janne Grunau	c829b35c08	lavc: er: remove unused variable size The code using it was removed in `d66e305bd1`.	11 years ago
Michael Niedermayer	4f22e39e65	avcodec/error_resilience: fix the case when MVs are not available Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Vittorio Giovara	e0c16e4e32	mpegvideo: move mpegvideo formats-related defines to mpegutils.h	11 years ago
Vittorio Giovara	d66e305bd1	er: move relevant fields from Picture to ERPicture This is done to disentangle ER from mpegvideo. In order to use a classic Picture, callers can use ff_mpeg_set_erpic() or use a custom function to set the fields. Please note that buffers need to be allocated before calling ff_er_frame_end().	11 years ago
Diego Biurrun	05563ccacc	dsputil: cosmetics: Lose camelCase on ff_cropTbl and ff_squareTbl names Also switch from "tbl" to "tab" name suffixes.	11 years ago

Michael Niedermayer	90539cea33	avcodec/error_resilience: check that er is supported before attempting to read the status of the previous slice Fixes incorrectly set error_occured and improves speed Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	afb18c5578	avcodec/error_resilience: factor er_supported() check out Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Diego Biurrun	19e30a58fc	Deprecate obsolete XvMC hardware decoding support XvMC has long ago been superseded by newer acceleration APIs, such as VDPAU, and few downstreams still support it. Furthermore XvMC is not implemented within the hwaccel framework, but requires its own specific code in the MPEG-1/2 decoder, which is a maintenance burden.	11 years ago
Anton Khirnov	f354f30836	error resilience: check error_concealment, not err_recognition. err_recognition is supposed to trigger detecting and reporting errors, not trying to fix them.	11 years ago

Michael Niedermayer	24e3f44aed	EC: fix dest index for non 420 chroma. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	70d54392f5	lowres2 support. The new lowres support is limited to decoders where lowres decoding is possible in high quality. I was not able to measure any speed difference, but if one is found the 2-3 lines that might affect speed can be made compile time conditional Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	2bcbd98459	Remove lowres video decoding This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Michael Niedermayer	903ccf71b7	error_concealment: Check that the reference is not NULL In normal picture decoding this does not need to be checked but as error concealment is run in the case of errors the availability of references is less certain. This may be fixed differently at some point so that all references are always filled in before the EC code, in which case this should then be changed to an assert() Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
