Måns Rullgård	669b558330	Set HAVE_FAST_CLZ if CPU has a fast count leading zeros instruction Originally committed as revision 21216 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ramiro Polla	00c081a8f0	Remove unused clip_table code. Originally committed as revision 30303 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago
Måns Rullgård	3d7453e056	configure: allow reverse auto-selection of options This adds the possibility to set foo_if and foo_if_any variables, causing foo to be enabled if all/any of the listed options are enabled. Originally committed as revision 21215 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	29b75f0b67	Change code so it uses 2 adds instead of one FFABS. About 1% faster ff_ac3_bit_alloc_calc_psd on Intel Atom, overall speedup not measurable though. Should have a bigger effect on systems without cmov or with very slow cmov. Originally committed as revision 21214 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Alexander Strange	f267d3ac75	Implement alpha channel decoding for BGR HuffYUV. Since BGR24 is decoded as BGR32, fill its alpha channel with 255 using the appropriate predictors. Originally committed as revision 21211 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Baptiste Coudurier	01d6bd525a	Do not split audio frames accross pes packets. This was not supported by some equipment and cisco analyzer. Originally committed as revision 21203 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Luca Abeni	6f284d197c	Surprisingly enough, the RTP muxer does not depend on the RTP protocol nor on network support. Originally committed as revision 21202 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Mike Scheutzow	907d916627	print more debug info about muxing parameters, patch by Mike Scheutzow, scheutzow at alcatel-lucent dot com Originally committed as revision 21201 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	fbb6c6c2d4	Define !CONFIG_FOO in config.make if feature disabled Originally committed as revision 21192 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	2ef21b9179	AAC: Reduce depth of vlc_spectral tables to 2 Up to 6% faster overall on i7, no change on A8. Originally committed as revision 21191 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	95dff4aced	AAC: Unswitch loop over window groups in decode_spectrum_and_dequant() GCC should be able to do this, but doesn't. Slightly faster code. Originally committed as revision 21190 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	05f9d8fcaa	AAC: simplify some calculations in decode_spectrum_and_dequant() Simplify cur_band_type, group_len, and coef/offset calculations. This makes the code easier to read and slightly faster. Originally committed as revision 21189 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c816d3d042	AAC: Compress codebook tables and optimise sign bit handling The codebooks each consist of small number of values repeated in groups of 2 or 4. Storing the codebooks as a packed list of 2- or 4-bit indexes into a table reduces their size substantially (from 7.5k to 1.5k), resulting in less cache pressure. For the band types with sign bits in the bitstream, storing the number and position of non-zero codebook values using a few bits avoids multiple get_bits() calls and floating-point comparisons which gcc handles miserably. Some float/int type punning also avoids gcc brain damage. Overall speedup 20-35% on Cortex-A8, 20% on Core i7. Originally committed as revision 21188 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	9d50d39629	Fix issue1658 (trailing space in rtpmap descriptor). Originally committed as revision 21187 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Tomas Härdin	094a63f1f6	Check there is a stream before writing header. Patch by Tomas Härdin: $(name) punto hardin chez codemill dot se Originally committed as revision 21186 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	ef5e7fb253	Remove needless use of log2f() Originally committed as revision 21185 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	1c3c129b8f	Remove the struct SiprModeParam of the context. This will simplify splitting the file for future 16k mode decoder code. Originally committed as revision 21184 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	f3da24c4c3	SIPR: kill variable-length arrays Two of these are in fact constant size, so use the constant instead of a variable in the declarations. The remaining one is small enough that always using the maximum size is acceptable. Originally committed as revision 21183 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	0cd73b6c30	remove unused variable Originally committed as revision 21182 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	8e71d89a7b	Move golomb_to_int*cbp tables back to h264_data.h as svq3.c used them. Yes i did compile&test, no svq3.c was not recompiled. Originally committed as revision 21180 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Zuxy Meng	0752cd39d2	More av_cold for infrequently called functions. Originally committed as revision 21179 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
Stefano Sabatini	08f8b51f69	Make avfilter_insert_filter() log the names of the filters between which it inserts the new filter. Originally committed as revision 21177 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	f37c934d20	Make query_formats() print an error message if an auto-inserted scale filter cannot convert between input and output formats. Originally committed as revision 21176 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	1460c79097	Use MULH instead of 64x64 multiplication, around 5% overall speedup on Intel Atom. Patch by myself and Yuriy Kaminskiy [yumkam mail ru] Originally committed as revision 21175 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
Thilo Borgmann	099809d19b	Reindent after last commit. Originally committed as revision 21171 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
