Alex Converse	c0893c3abb	AAC: Unroll code within decode_spectrum_and_dequant(). Gives 12% net speed gain. Patch by Alex Converse (alex converse gmail com) Originally committed as revision 16040 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Stefano Sabatini	dbbec0c2f2	Make av_log_missing_feature an internal function, and change its name to ff_log_missing_feature. Originally committed as revision 16037 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Alex Converse	d0ee50216d	Fix perceptual noise shaping scaling including an oversight of the offset for the EIGHT_SHORT window type. Fixes issue 664. Patch by Alex Converse (alex converse gmail com) Originally committed as revision 15776 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Aurelien Jacobs	37d3e0667a	uses FF_ARRAY_ELEMS() where appropriate Originally committed as revision 15662 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	fbdae895f2	Rename variables to clarify the channel coupling element and corresponding target channel element. Patch by Alex Converse (alex converse gmail com) Originally committed as revision 15575 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	88de95c2f9	Corrections to channel coupling code to attain conformance for appropriate streams. Slightly reworked from a patch by Alex Converse (alex converse gmail com) Originally committed as revision 15573 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Robert Swain	341b28c0d2	Zero 'idx' for each iteration of the coupling gain loop and as it is only used within this loop, we can move its declaration there too. This fixes bitstream desync when decoding streams containing CCEs. Based on a patch by Alex Converse (alex converse gmail com) Originally committed as revision 15364 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Robert Swain	f80a8ca5cb	Cosmetics: missing brackets Originally committed as revision 15363 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Alex Converse	c8947a5612	Cast the return value of get_bits() to signed integer such that the subtraction is conducted as a signed calculation. Patch by Alex Converse (alex converse gmail com) Originally committed as revision 15362 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Alex Converse	aac0eda407	Validate pulse position and error out if an invalid position is encountered. Patch by Alex Converse (alex converse gmail com) Originally committed as revision 15340 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Robert Swain	70735a3f9e	Reindent after last commit Originally committed as revision 15315 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Alex Converse	5143684891	Apply pulses to unscaled coefficients rather than scaled. Slight reworking of a patch by Alex Converse (alex converse gmail com) Originally committed as revision 15314 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Robert Swain	408992bae2	Operands of '+' are not necessarily evaluated in order so r15311 was pointless. Splitting the assignment onto two lines should resolve the order issue. Originally committed as revision 15313 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Alex Converse	19645d742e	Correct order of parsing for pulse scalefactor band and offset to match the specification. Patch by Alex Converse (alex converse gmail com) Originally committed as revision 15311 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Robert Swain	35445d29f5	Reindent after last commit Originally committed as revision 15304 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Alex Converse	5167364777	Only read some of TNS bitstream data in the case that the TNS filter order is non-zero as per the specification. Patch by Alex Converse (alex converse gmail com) Fixes another issue pertaining to issue632 Originally committed as revision 15303 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Robert Swain	febcbd65fa	Correct pulse amplitude application - a negative or 0 coefficient implies the pulse is subtracted, else it is added. Also avoid a divide by 0. Based on a patch by Alex Converse (alex converse gmail com) Fixes part of issue632 Originally committed as revision 15294 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	1775c7fac6	Multiply table by -1. This avoid doing this calculation (that was introduced in my last commit) in real time. Originally committed as revision 15195 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Robert Swain	f4fae46e67	Remove unnecessary portion of a condition. This fixes issue607 and avoids another unintended bug where channel coupling could have been run on an SCE. Originally committed as revision 15036 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Robert Swain	b0f5852a13	Use ff_imdct_half() and vector_fmul_window() for IMDCT and windowing. Reduce buffer sizes accordingly. This produces a ~10% overall decoding perfomance improvement. Originally committed as revision 14908 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
