Alex Converse	4d986b7172	aacenc: Use exact values when quantizing, not fuzzy values. This requires us to code small escapes; we can't avoid it. Originally committed as revision 23135 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	51cbabc792	aacenc: Use an estimated codebook for the TLS (two loop search). Originally committed as revision 23134 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	46174079c9	10l: store the result of clipping added in r23035 Originally committed as revision 23037 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	32fa7725d2	Make the faac inspired quantizer search make sense for a slightly narrower definition of "make sense." Originally committed as revision 23035 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	508f092a78	aacenc: Merge quantize_band_cost() with quantize_and_encode_band(). If these two functions aren't matched results may be unexpected. Originally committed as revision 22655 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	f5e82fec3d	aacenc: Use preprocessor constants for trellis states and stages. Originally committed as revision 19948 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	9072c29e40	aacenc: Split paths in the scalefactor selection trellis into a 2-D array. Originally committed as revision 19947 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	9d4f6f10ae	aacenc: Replace cbrt() with cbrtf() when the result is destined for float storage. Originally committed as revision 19946 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	0bd9aa449a	aacenc: Multiple distortion by lambda after it's summed and not each individual term before. Originally committed as revision 19945 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	06d6b962e5	Cosmetics: Reindent after r19943. Originally committed as revision 19944 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	a71e9b6254	aacenc: Don't make unnecessary compares to the escape value in tight loops. Originally committed as revision 19943 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	dd0e43e4bb	Re-add search_for_ms to the coefficients encoders to silence warnings Originally committed as revision 19733 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	a62d6cfeff	Be sure to increment our position in the coefficient array when skipping a zero band in the twoloop scalefactor search. Originally committed as revision 19480 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	5cf20d07ad	Remove an unused field from the BandCodingPath struct. Originally committed as revision 19473 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	0193992252	Actually use all the codebooks we are iterating over in the two-loop scalefactor search. Originally committed as revision 19472 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	932e6a5a4c	Fix an integer overflow in the AAC encoder. Originally committed as revision 19470 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	3d51be014c	Replace pow(x, 0.75) with sqrtf(x * sqrtf(x)) for a 33% speedup. Originally committed as revision 19459 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	c369e83608	Dead code removal in the AAC encoder. Originally committed as revision 19457 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	a5762c9b59	When calculating AAC quantized band cost, don't leave garbage in the bit count for the 0 codebook. Originally committed as revision 19444 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	988c170547	Change fminf/fmaxf to FFMIN/FFMAX to fix the build on broken operating systems. Originally committed as revision 19391 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	7a4eebcdce	Turn on AAC rate control. Originally committed as revision 19379 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	c8f47d8b79	cosmetics: Remove unnecessary {} around if/for blocks; move statements after if/for to the next line. Originally committed as revision 19378 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	99d61d340c	cosmetics: prettyprinting, K&R style, break overly long lines Originally committed as revision 19377 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	fd257dc4c0	Cosmetics: Pretty print the AAC encoder. Originally committed as revision 19376 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	78e65cd772	Merge the AAC encoder from SoC svn. It is still considered experimental. Originally committed as revision 19375 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
