Diego Biurrun	368f50359e	dsputil: Split off quarterpel bits into their own context	11 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	82bb304801	dsputil: Use correct type in me_cmp_func function pointer	11 years ago
Vittorio Giovara	e0c16e4e32	mpegvideo: move mpegvideo formats-related defines to mpegutils.h	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	b5b7b75e91	dsputil: Move get_penalty_factor() to the only place it is used.	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

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	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

Michael Niedermayer	56bf2c2a19	motion_est: avoid generating motion vectors that point between widthxheight and mb_widthxmb_height. No difference in PSNR or bitrate in the printed precission with the matrix lobby scene at 322x242 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	cb668476ab	motion_est: make MotionExtContext.map_generation unsigned The way this value is used, it should be an unsigned type. While the numerical value has no meaning, unsigned wraparound is relied upon. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Reimar Döffinger	b0c73ba11f	motion_est: fix implicit truncation warnings Patch by Reimar Döffinger and Eli Friedman (independently). Originally committed as revision 24083 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	fd8277ffa0	Optimize bidir_refine a bit. compiled code is less tham 1/4 the size. a tiny bit faster Originally committed as revision 22777 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	a69220cce0	Change bidir refine hash code so we only need to perform a single hash calculation for the whole function. negligibly faster (about 0.1%) Originally committed as revision 22775 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	2d603902f3	Reduce the size of the bidir refine hashtable from 4096 to 256 and change the hash function to something more sane and simple. about 1/3 faster, no meassureable change in psnr or size and i gues its even same md5 with my test file but i forgot testing that. Originally committed as revision 22773 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	e056d2a24b	Move comment that belonged to cmp() back to cmp(). Originally committed as revision 22772 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	919e749772	slice dice, inline and outline cmp() motion_est.o is now less than half its previous size. No speedchange meassureable. Originally committed as revision 22771 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
