Alexander Kojevnikov	49d7ef282d	Show correct bitrate for VBR MP3 files. Patch by Alexander Kojevnikov, alexander kojevnikov com Originally committed as revision 24539 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefan Gehrer	de29597680	add Chinese AVS encoding via external library libxavs Originally committed as revision 24533 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	126b638ea0	Deprecate av_parse_video_frame_size() and av_parse_video_frame_rate() in favor of the newly added corresponding functions av_parse_video_size() and av_parse_video_rate() defined in libavcore/parseutils.h. This change also adds a linking-time dependency of libavcodec and of libavfilter on libavcore. Originally committed as revision 24518 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	ab4d031889	Use pmaddubsw for the mbedge_filter (>=ssse3), 6-10 cycles faster. Originally committed as revision 24514 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	e25dee602f	VP8: Much faster SSE2 MC 5-10% faster or more on Phenom, Athlon 64, and some others. Helps some on pre-SSSE3 Intel chips as well, but not as much. Originally committed as revision 24513 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
S.N. Hemanth Meenakshisundaram	9dd9d67bd0	Define static functions fill_image_linesize() and fill_image_data_ptr(). ff_fill_linesize() and ff_fill_pointer() now wrap these functions. The new functions are more generic, and are going to be exported in a future patch. Patch by S.N. Hemanth Meenakshisundaram smeenaks # ucsd § edu. Originally committed as revision 24512 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	48adb7e7a4	Enable no-loop memory/register saving for ssse3/sse4 also. Originally committed as revision 24511 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	2a180c69ea	Save a register (or regsize of stackspace for x86-32) for the no-loop mbedge loopfilter functions, by re-using space that holds a variable that we no longer need. Originally committed as revision 24510 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	bcd4aa6498	Use nested ifs instead of &&, which appears to not work with %ifidn (i.e. this construct was always enabled, even for <ssse3 versions). Originally committed as revision 24509 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Axel Holzinger	0b2c75cb68	Rename pow variable to pwr. Patch by Axel Holzinger <aholzinger gmx de>. Originally committed as revision 24508 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	2208053bd3	Split pextrw macro-spaghetti into several opt-specific macros, this will make future new optimizations (imagine a sse5) much easier. Also fix a bug where we used the direction (%2) rather than optimization (%1) to enable this, which means it wasn't ever actually used... Originally committed as revision 24507 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	fca05ea8a0	VP8: add missing free Fixes a tiny memory leak. Originally committed as revision 24504 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Carl Eugen Hoyos	28e241de5d	Fix r24445: Instead of needlessly initialising a variable, silence the warning. Originally committed as revision 24498 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Carl Eugen Hoyos	b9542223a3	Only 4-bit ADPCM IMA WAV files are supported. Originally committed as revision 24493 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	6de5b7c6b8	Fix obvious bug in assignment. Somehow, the test vectors don't test this... Originally committed as revision 24489 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Aurelien Jacobs	ba2c508d0c	add SubRip muxer and demuxer Originally committed as revision 24488 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	e3f7bf774c	Fix SPLATB_REG mess. Used to be a if/elseif/elseif/elseif spaghetti, so this splits it into small optimization-specific macros which are selected for each DSP function. The advantage of this approach is that the sse4 functions now use the ssse3 codepath also without needing an explicit sse4 codepath. Originally committed as revision 24487 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	63e1278d88	aacenc: TLS: Save maximum values for each swb in a table. This gives an almost 20% speedup. Originally committed as revision 24484 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	031d5cea04	10l: Remove some commented out code that slipped in. Originally committed as revision 24483 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	fe461767e6	aacenc: TLS: Try to preserve some energy in each non-zero band. Reduce scalefactors in non-zero bands that underflow by twice as much as those in bands that just fail to hit psy targets. Originally committed as revision 24482 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	edac49daf5	Use "const" qualifier for pointers that point to input data of audio encoders. This is purely for clarity/documentation purposes. Originally committed as revision 24481 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	c226fc5bfb	aacenc: Prevent premature termination of the two loop search. Originally committed as revision 24476 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	81824fe059	aacdec: Only load and write each predictor variable once. This is slightly faster and opens the door for further optimization. Originally committed as revision 24475 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	70c99adb48	aacdec: 4% faster main profile decoding. Originally committed as revision 24474 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	51ffd3a62f	aacenc: Favor log2f() and sqrtf() over log2() and sqrt(). Originally committed as revision 24473 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	04d72abf17	aacenc: Factorize some scalefactor utilities. Originally committed as revision 24472 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Eli Friedman	3611e7a309	Inline asm for VP56 arith coder This is a lot more reliable to get cmov rather than trying to trick gcc into generating it, useful since it's 2% faster overall. Patch by Eli Friedman <eli.friedman at gmail> Originally committed as revision 24471 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	ca18a478e3	VP8: Inline traversing vp8_small_mvtree Much faster read_mv_component, slightly faster overall Originally committed as revision 24470 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	7697cdcf95	VP8: Use vp56_rac_get_prob_branchy when the bit is only used by an if() Originally committed as revision 24469 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	fe1b5d974a	Decode DCT tokens by branching to a different code path for each branch on the huffman tree, instead of traversing the tree in a while loop. Based on the similar optimization in libvpx's detokenize.c 10% faster at normal bitrates, and 30% faster for high-bitrate intra-only Originally committed as revision 24468 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	5474ec2ac8	Move renormalization of the VP56 arith decoder to before decoding a bit No difference at the moment, but allows a future branchy variant of vp56_rac_get_prob to be significantly faster Originally committed as revision 24467 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	b3d755ec8b	Split renorm of vp56 arith decoder to its own function Originally committed as revision 24466 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	24675b8093	vp56's arith decoder's code_word is only 16 bits, no need for unsigned long Originally committed as revision 24465 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	13a1304bb3	Add myself to VP8 copyright and maintainers. Also add Ronald to maintainers. Originally committed as revision 24464 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	414ac27d8f	VP8: always_inline some things to force gcc to do the right thing Mostly seems to help in the MC code, which gets a hundred cycles faster. Originally committed as revision 24463 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	06d50ca804	VP8: use AV_RL24 instead of defining a new RL24. Originally committed as revision 24462 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	9fddd14a8e	VP8: Slightly faster MV selection Don't clamp best mv unless it's actually used. Originally committed as revision 24461 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
