Jason Garrett-Glaser	63c0b3d920	Various VP3 optimizations. Faster checks in reverse_dc_prediction. Simplified deblocking checks. Check transform==15 first, since it's more common than 13. Originally committed as revision 20747 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	a4605efdf5	slightly faster scalarproduct_and_madd_int16_ssse3 on penryn, no change on conroe Originally committed as revision 20743 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	91e644ff77	r20739 broke compilation on systems without yasm Originally committed as revision 20742 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	b1159ad928	refactor and optimize scalarproduct 29-105% faster apply_filter, 6-90% faster ape decoding on core2 (Any x86 other than core2 probably gets much less, since this is mostly due to ssse3 cachesplit avoidance and I haven't written the full gamut of other cachesplit modes.) 9-123% faster ape decoding on G4. Originally committed as revision 20739 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	442d7dd852	Make sure the parsers do not overwrite width/height as this can interfere with the decoder. Fixes issue1135. Originally committed as revision 20736 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	78149213cc	Cosmetics: remove empty definitions of hw-accelerated PixFmtInfo structs. Originally committed as revision 20733 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Kostya Shishkov	1e68cefe54	100l trocadero: call emms_c() after doing decoding with SIMD in APE decoder Originally committed as revision 20727 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	ccc4b91832	Make sure ff_init_qscale_tab() is called one way or another when adaptive quantization is enabled. Fixes issue509. Originally committed as revision 20726 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	9015b095bc	Move ff_init_qscale_tab() from h263.c to mpegvideo, the function is not h263 specific. Originally committed as revision 20725 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Baptiste Coudurier	bdcc13f2bf	lzw.h does not need get_bits.h, tiff.c needs intreadwrite.h for AV_R* though Originally committed as revision 20724 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	c267bb038e	Fix 1 pass RC in snow. Fixes issue547. Originally committed as revision 20706 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c5d6cd5c81	ARM: 1l c&p fix: do not set pred16x16_plane for rv40 Originally committed as revision 20705 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	702b5885a1	ARM: NEON optimised H264 16x16, 8x8 pred Originally committed as revision 20704 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	4fab662769	AAC: Add a global header but output not locked output configuration status. Originally committed as revision 20701 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	38610d92ff	Set the SBR mode to implicit on ADTS frames occurring before the output is locked. Originally committed as revision 20700 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Mike Melanson	9d8bb0318a	Small refactoring: Instead of 4 loops for decoding AC coefficients based on their grouping, create one loop that indexes into a table of AC VLC tables. There is also a small optimization here: Do not call unpack_vlcs() if there are no fragments in the list with outstanding coefficients. My profiling indicates that this can save upwards of 1 million dezicycles per frame throughout the course of unpack_dct_coeffs(). Originally committed as revision 20699 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Mike Melanson	098523eb28	Use a list to track which fragments coded in this frame still have outstanding coefficients yet to be decoded from the bitstream. Once a fragment reaches end-of-block, remove it from this new list. This change makes the VP3/Theora entropy decode process dramatically faster due to not having to iterate incessantly over fragments which have already been fully decoded. Originally committed as revision 20698 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	94f28061f5	Store original width/height so that rv20 does not get stuck with some resolution. A sample file to show a difference is at issue833 (http://airfarce.com/video/000211fh.rm) Originally committed as revision 20691 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	483aad717e	slif aka "SoftLab MPEG-2 I-frames Codec" support. Flipping one bit still is popular it seems as a means to create a new codec. fixes issue1469. Originally committed as revision 20679 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	52069c4d3c	Move "slice below image" check from mpeg_decode_slice to its caller. Should fix issue1277. Originally committed as revision 20676 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	d52b4abe8b	Move dummy picture allocation code from mpeg1/2 to mpegvideo. This fixes a infinite loop on a b frame. Originally committed as revision 20672 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	fd1ef13bb4	Disable error resilience for field pictures, this was never supported, results where more or less random but should not have crashed. Originally committed as revision 20671 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	078cdecf9e	Set mb_y in mpeg2 field pictures like h264 does. This fixes -vismv & -debug 16384 with field pictures. Originally committed as revision 20670 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	22d4f21331	Make ""MPEG motion vector out of boundary" message more verbose. Originally committed as revision 20669 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Attila Kinali	76c4a644ee	Fix an issue uncovered by commit 20623: The init functions of mpc7 and mpc8 check whether the vlc has been initialized already and return early if this is the case (eg by calling init a second time). But avctx->sample_fmt and channel_layout is set after the vlc initialization, causing it not to be set on the second call of init. Move all manipulations of avctx before the initialization of the vlc, so that it is always set. Originally committed as revision 20668 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	ab8c48de8c	Start decoding from seq/gop too, not just I frames. Possibly fixes issue1124. Originally committed as revision 20667 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
