Michael Niedermayer	24f5136196	avcodec/mpegvideo: Do not clear the parse context during init It is allocated before, this cannot work Fixes Ticket5613 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Michael Niedermayer	39c0b22df4	avcodec/mpegvideo: Deallocate last/next picture earlier Fixes regression with mplayers direct rendering and reduces buffer count pressure in some cases Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Luca Barbato	7d4a1ff344	mpegvideo: Fix undefined negative shifts in ff_init_block_index Found-by: gcc5-ubsan. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Derek Buitenhuis	21f9468402	avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPAT Libav, for some reason, merged this as a public API function. This will aid in future merges. A define is left for backwards compat, just in case some person used it, since it is in a public header. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago
Vittorio Giovara	1482aff204	lavc: Move noise_reduction to codec private options This option is only used by mpegvideoenc, x264, xavs, and vpx. It is a very codec-specific option, so deprecate the global variant. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Clément Bœsch	56bdf61baa	avutil/motion_vector: export subpel motion information FATE test changes because of the switch from shift to division.	9 years ago
Andreas Cadhalpun	6a69a175e7	mpegvideo: clear overread in clear_context Otherwise the h263p decoder can try to copy overread bytes, even though buffer is NULL. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>	9 years ago
Ganesh Ajjanagadde	c5fa42c69a	avcodec/mpegvideo: use predefined M_PI M_PI is defined in math.h, or in avutil/mathematics.h for compatibility hacks. This uses this value instead of an ad-hoc floating literal. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago
Michael Niedermayer	58fe57d5a0	avcodec/mpeg12enc: Basic support for encoding non even QPs for -non_linear_quant 1 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Vittorio Giovara	c6aa0554b0	mpegvideo: Drop release_unused_pictures() function It is only used in one place, and it is small enough that it might be called directly.	10 years ago
Vittorio Giovara	7061bf0925	mpegvideo: Move Picture-related functions to a separate file	10 years ago
Vittorio Giovara	9bb11be0e5	mpegvideo: Split picture allocation for encoding and decoding The main ff_alloc_picture() function is made more generic with all the parameters necessary as arguments. This will allows to move most of the related functions to a separate file later. Right now wrappers are provided to try and minimize the number of changes in the code.	10 years ago
