Mans Rullgard	3824ef08e0	ARM: allow unaligned buffer in fixed-point NEON FFT4 This function is called with only 8-byte alignment from imdct for size 16. The fft4 function is not called for the larger FFT or MDCT sizes, so this has no impact on typical uses. Signed-off-by: Mans Rullgard <mans@mansr.com>	2011-07-04 20:36:35 +01:00
John Stebbins	49c7006c7e	dca: set AVCodecContext frame_size for DTS audio Set the frame size when decoding DTS audio. This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields. Since frame_size is not currently set, the duration of a frame is being guessed based on the streams bitrate. But for DTS-HD, the bitrate currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly inaccurate frame duration estimate.

In adjust_frame_information(), msc is incremented for each sfb in each sub-window then compared against max_sfb which is for a single sub-window.

Mike Scheutzow	aa15e68721	Fix decoding of mpegts streams with h264 video that does NOT have b frames One of the causes of this bug is that the h264 parser defaults low_delay to 1, but the h264 codec defaults low_delay to 0. Really Ugly. After many hours of looking at this, I'm still not sure how has_b_frames is intended to behave, but to me the implementation appears way more complicated than it ought to be. My patch relies on the encoder to set an optional field in the SPS. This works for libx264 streams, but I'm not sure that all h264 encoders will set it.

Diego Biurrun	046f081b46	configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS. Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems since it causes certain system functions to be hidden on some (BSD) systems. The solution is to only add the flag on systems that really require it, i.e. glibc-based ones. This change makes BSD systems compile out-of-the-box without the need for adding specific flags manually. It also allows dropping a number of flags set manually on a file-per-file basis, but were only present to work around breakage introduced by the presence of _POSIX_C_SOURCE. Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems. We use XSI extensions in several places already, so it is preferable to define it globally instead of littering source files with individual #defines only needed for glibc.	2011-05-12 11:41:59 +02:00

The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size.

Alex Converse	187a537904	Convert some undefined 1<<31 shifts into 1U<<31. According to ISO 9899:1999 S 6.5.7/4: The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits are filled with zeros. If E1 has an unsigned type, the value of the result is E1× 2^E2, reduced modulo one more than the maximum value representable in the result type. If E1 has a signed type and nonnegative value, and E1× 2^E2 is representable in the result type, then that is the resulting value; otherwise, the behavior is undefined.	2011-04-11 21:47:42 -07:00

Justin	323e6fead0	ac3enc: do not right-shift fixed-point coefficients in the final MDCT stage. This increases the accuracy of coefficients, leading to improved quality. Rescaling of the coefficients to full 25-bit accuracy is done rather than offsetting the exponent values. This requires coefficient scaling to be done before determining the rematrixing strategy. Also, the rematrixing strategy calculation must use 64-bit math to prevent overflow due to the higher precision coefficients.	2011-03-14 08:45:26 -04:00

Justin Ruggles	5fc2e0075d	cosmetics: rename block_num to blk for variable name consistency Originally committed as revision 26353 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-15 01:58:55 +00:00
Justin Ruggles	0429e4a6ca	Move exp_strategy from AC3Block to AC3EncodeContext in order to arrange by channel first, then by block. Originally committed as revision 26352 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-15 01:58:50 +00:00
Justin Ruggles	7cc4be58b4	Rearrange exponent buffer to group all blocks for a single channel together. This will allow for faster and simpler processing of all blocks at once. Originally committed as revision 26351 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-15 01:58:45 +00:00
Jason Garrett-Glaser	2a1f431d38	H.264/SVQ3: make chroma DC work the same way as luma DC No speed improvement, but necessary for some future stuff. Also opens up the possibility of asm chroma dc idct/dequant. Originally committed as revision 26349 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-15 01:10:46 +00:00
Jason Garrett-Glaser	290fabc684	Port SVQ3 to use the new mb_luma_dc method of storing luma DC coefficients. Doesn't help speed as there isn't an asm implementation yet, but consistency is a good thing. Originally committed as revision 26348 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-15 00:41:18 +00:00
Sascha Sommer	3cdf69eefa	also support decoding of AVPackets with multiple wma packets fixes issue 2539 Originally committed as revision 26346 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-14 23:58:55 +00:00
Jason Garrett-Glaser	65344775b8	H.264: Remove useless arg to chroma_dc_dequant_idct_c Originally committed as revision 26345 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-14 23:46:55 +00:00
Ronald S. Bultje	ec3233a855	Fix ff_pw_3 alignment. Originally committed as revision 26344 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-14 23:26:34 +00:00
Jason Garrett-Glaser	2e18660115	Fix SVQ3 Regression in r26336-7. Originally committed as revision 26341 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-14 22:23:42 +00:00
Jason Garrett-Glaser	bd11c7a1a8	Remove outdated comment in h264dsp.h Since we no longer have non-transposed scantables, the problem it warns about no longer exists. Originally committed as revision 26339 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-14 21:48:33 +00:00
Jason Garrett-Glaser	0d1d01cf70	Reindent after r26337. Originally committed as revision 26338 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-14 21:36:45 +00:00
Jason Garrett-Glaser	5657d14094	H.264: switch to x264-style tracking of luma/chroma DC NNZ Useful so that we don't have to run the hierarchical DC iDCT if there aren't any coefficients. Opens up some future opportunities for optimization as well. Originally committed as revision 26337 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-14 21:36:16 +00:00
Jason Garrett-Glaser	19fb234e4a	H.264: split luma dc idct out and implement MMX/SSE2 versions About 2.5x the speed. NOTE: the way that the asm code handles large qmuls is a bit suboptimal. If x264-style dequant was used (separate shift and qmul values), it might be possible to get some extra speed. Originally committed as revision 26336 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-14 21:34:25 +00:00
Jason Garrett-Glaser	ca32f7f208	H.264: eliminate non-transposed scantable support. It was an ugly hack to begin with and didn't give any performance. NOTE: this patch opens up some future simplifications to be made (such as removing some of the scantables from H264Context) but doesn't take advantage of them yet. Originally committed as revision 26329 to svn://svn.ffmpeg.org/ffmpeg/trunk	2011-01-14 19:04:59 +00:00
