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>	9 years ago
Vittorio Giovara	4b6b1082a7	lavc: Deprecate avctx.me_method This option is extremely codec specific and only a few codecs employ it. Move it to codec private options instead: mpegenc family supports only 3 values, xavs and x264 use 5, and xvid has a different metric entirely.

Vittorio Giovara	0251c9be5a	motion_est: Fix warning from zero_cmp() assignment warning: incompatible pointer types assigning to 'me_cmp_func' (aka 'int ()(struct MpegEncContext , uint8_t , uint8_t , ptrdiff_t, int)') from 'int (MpegEncContext , uint8_t , uint8_t *, int, int)' [-Wincompatible-pointer-types]	10 years ago

Anton Khirnov	a2941c8cb2	lavc: move CODEC_FLAG_MV0 to mpegvideo	11 years ago
wm4	f6774f905f	mpegvideo: operate with pointers to AVFrames instead of whole structs The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	11 years ago

Diego Biurrun	088f38a4f9	avcodec: Drop unnecessary ff_ name prefixes from static functions	12 years ago
Ronald S. Bultje	f4fed5a2f9	mpegvideo: Use hpeldsp instead of dsputil for half-pel functions This also converts vc1, since that is mpegvideo-based. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Anton Khirnov	6e7b50b427	mpegvideo_enc: drop support for reusing the input motion vectors. This misfeature is most likely completely useless and conflicts with removing the mpegvideo-specific fields from AVFrame. In the improbable case it is actually useful, it should be reimplemented in a better way.	12 years ago
Diego Biurrun	c242bbd8b6	Remove unnecessary dsputil.h #includes	12 years ago

Diego Biurrun	25841dfe80	Use ptrdiff_t instead of int for {avg, put}_pixels line_size parameter. This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic.	12 years ago
Anton Khirnov	47318953dd	mpegvideo: remove some unused variables from Picture.	12 years ago
Michael Niedermayer	bbe56bcd6b	motion_est: Limit motion vector search range to MAX_MV Fixes out of array reads with videos exceeding MAX_MV Found-by: Thierry Foucu Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Diego Biurrun	a0c5917f86	Drop Snow codec Snow is a toy codec with no real-world use and horrible code.	12 years ago

Mans Rullgard	a34a609fc1	motion_est: fix use of inline on extern functions Inline functions declared without extern do not provide an external definition in standard C99. This code only works because most compilers do not implement the inline semantics correctly. With a stricter compiler, linking fails with unresolved references to these functions. Declaring the functions extern inline works correctly with some compilers while some others still fail to create external definitions. For maximum portability, create a static inline version with an externally visible wrapper for ff_get_mb_score. ff_epzs_motion_search is so large that no sane compiler inlines it anyway, so there the inline keyword can simply be dropped with no effect.

Mans Rullgard	0db9eba48c	motion_est: drop inline from sad_hpel_motion_search() This function is only ever called through a function pointer, so marking it inline makes no sense. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	5bf7bc625b	motion_est: remove unused macros Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	74f82f92a4	motion_est: remove useless no_motion_search() function At both places this function is called, mb_[xy] == s->mb_[xy] making the call together with following code equivalent to simply assigning zeros. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
