Michael Niedermayer	599fe45b8d	Split fill_caches() between loopfilter & decode, the 2 no longer where common enough to justify the messy interleaving. Originally committed as revision 21469 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	dfe4dc154b	use left_xy[1] in mbaff QP loop filter check, this improves the amount that can be skiped. Originally committed as revision 21465 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	5cc5d9bf29	Remove unneeded for_deblock check, this code was alraedy under for_deblock. Originally committed as revision 21304 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	a7d7cdaac7	Set h->cbp for ff_h264_filter_mb_fast(). Originally committed as revision 21287 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	b6ef858ec7	Move CAVLC 8x8 DCT special case from ff_h264_filter_mb() to fill_caches that way it is also available for ff_h264_filter_mb_fast(). Originally committed as revision 21283 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	6d7e6b2657	Perform reference remapping at fill_cache() time instead of in the loop filter. This removes one obstacle of getting ff_h264_filter_mb_fast() bitexact. code is maybe 0.1% faster Originally committed as revision 21280 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	7da0d82104	Make qp check for loop filter skiping also work with MBAFF. Originally committed as revision 21276 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	12be38ec18	Comment about a cornercase we ignore currently Originally committed as revision 21275 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	44a5e7b64c	Move the qp check to skip the loop filter up. Originally committed as revision 21274 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	b6303e6d2a	Reorganize how values are stored in h->non_zero_count. ~1% faster Originally committed as revision 21273 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	2911e13224	Disable a few things in fill_filter_caches() that arent needed. 0.1% speedup Originally committed as revision 21272 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	f432b43b08	Split fill_caches() between filter and decoder. Originally committed as revision 21271 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	c988f97566	Rearchitecturing the stiched up goose part 1 Run loop filter per row instead of per MB, this also should make it much easier to switch to per frame filtering and also doing so in a seperate thread in the future if some volunteer wants to try. Overall decoding speedup of 1.7% (single thread on pentium dual / cathedral sample) This change also allows some optimizations to be tried that would not have been possible before. Originally committed as revision 21270 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	2e36c931f0	Avoid wasting 4 cpu cycles per MB in redundantly calculating qp_thresh. Originally committed as revision 21243 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	ddd60f28d8	Replace cabac checks in inline functions from h264.h with constants. No benchmark because its just replacing variables with litteral constants (so no risk for slowdown outside gcc silliness) and i need sleep. Originally committed as revision 21237 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	7c2de274e7	Add forgotten include of h264_mvpred.h to h264.h. This could have caused the linking failure of pred_pskip_motion() missing if a compiler included never used static functions. Originally committed as revision 21221 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	cc51b28299	Split cabac decoding code out of h264.c. not slower according to benchmarks. Originally committed as revision 21181 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	e1e949026e	Split cavlc out of h264.c. Seems to speed the code up a little... The placement of many generic functions between h264.c and h264.h is still open Currently they are a little randomly placed between them. Originally committed as revision 21178 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	188d3c510d	Split motion vector prediction off h264.c/h. Originally committed as revision 21174 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	2bedc0e854	Move check_intra4x4_pred_mode() back from h264.h to h264.c, the function is just called once per MB in worst case and doesnt seem to benefit from static inline. Actually the code might be a hair faster now (0.1% according to my benchmark but this could be random noise) Originally committed as revision 21173 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	ea6f00c448	Split all the reference picture handling off h264.c. Originally committed as revision 21172 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	889fce8e30	Split (picture\|seq) parameter set decoding out of h264.c. no speedloss meassured, also its really not touching anything that is speed relevant. Originally committed as revision 21169 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	9c09546352	Split SEI code off h264.c. Originally committed as revision 21168 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	943f69a6ea	Split direct mode (macro)block decoding off h264.c. No speedloss meassured (its slightly faster here but that may be random fluctuations) Originally committed as revision 21165 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	082cf97106	Split h264 loop filter off h264.c. No meassureable speed difference on pentium dual & cathedral sample. Originally committed as revision 21159 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	903d58f631	Get rid of #include "svq3.c" functions called more than per mb are moved into the header, scan8 is also as it must be known at compiletime. The code after this patch duplicates h264data.h, this has been done to minimize the changes in this step and allow more fine grained benchmarking. Speedwise this is 1% faster on my pentium dual core with diegos cursed cathedral sample. Originally committed as revision 21157 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	c4dffe7e36	Export fullrange flag and color information for h.264 Originally committed as revision 21126 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Laurent Aimar	75dd693840	Export get_slice_type() as ff_h264_get_slice_type(). Patch by Laurent Aimar <fenrir at videolan dot org>. Originally committed as revision 21110 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Haruhiko Yamagata	b19d493f2b	Add field prev_interlaced_frame to H264Context to be able to flag soft telecine progressive. Patch by Haruhiko Yamagata, h D yamagata A nifty D com Originally committed as revision 19141 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	cbf1eae9a5	Add forgotten void return type to ff_h264_free_context Originally committed as revision 18411 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	15861962a7	Add a ff_h264_free_context function and call it from the H.264 parser. This ensures that the parser will no longer leak memory for all SPS/PPS it encounters. Originally committed as revision 18406 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ivan Schreter	70e01da3bf	Add support for ct_type to correctly detect interlaced flag Originally committed as revision 17811 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
