Alex Converse	f8a93a2036	aac: Don't bias output during the IMDCT if SBR will be used. Originally committed as revision 22515 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	6ebc724060	aacsbr: Check that bs_num_env is valid before writing arrays with it as an offset. Originally committed as revision 22413 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	134b8cbb9a	aacsbr: Cleanup read_sbr_grid and copy_sbr_grid after the recent overhaul of those functions. Originally committed as revision 22412 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	f7e7888b2a	aacsbr: Factor out the common end border case from t_q setup. Originally committed as revision 22411 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	ac8d655a79	aacsbr: read bs_rel_bord directly into t_env. Originally committed as revision 22410 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	ecc1f8c3c8	aacsbr: Make the previous value of bs_num_env local to read_sbr_data(). Originally committed as revision 22409 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	46751a65e3	aacsbr: Initialize e_a[1] to -1. This triggers lAPrev (e_a[0]) on the first SBR frame to be -1. The spec is somewhat ambiguous to what this value should be but this increases the accuracy of al_sbr_e_44_1 and similar streams from 14 bits to 15 bits. Originally committed as revision 22408 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	5889172087	aacsbr: Dead code removal. Originally committed as revision 22387 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	afd96c345f	aacsbr: Remove a slightly incorrect comment. The two conditions are equivalent. Originally committed as revision 22386 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	7935078623	aacsbr: Cleanup the newly merged read_sbr_grid, eliminating several context and some duplicate local variables. Originally committed as revision 22384 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	7333f849b1	aacsbr: Move the e_a calculation from sbr_mapping() to read_sbr_grid(). Originally committed as revision 22383 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	b9c3e3b6e7	aacsbr: Merge sbr_time_freq_grid into read_sbr_grid (and into copy_sbr_grid). Originally committed as revision 22382 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	ed1d112931	aacsbr: Fail early on illegal envelope counts. Originally committed as revision 22381 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	8a9ee4b102	aacsbr: Check for illegal values of bs_pointer in sbr_read_grid(). Originally committed as revision 22380 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	bf3d904c3d	10l: Include missing return values in functions made non-void by the previous commit. Originally committed as revision 22376 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	58b1cba0c9	aacsbr: Propagate errors from read_sbr_grid to prevent crashes in malformatted streams. Originally committed as revision 22375 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Georgi Chorbadzhiyski	e0be763052	Add a missing fft.h include to the aacsbr decoder. Patch by Georgi Chorbadzhiyski gf at unixsol dot org Originally committed as revision 22374 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	ed492b61db	Add an HE-AAC v1 decoder. A large portion of this code was orignally authored by Robert Swain. The rest was written by me.
