* | avcodec/aactab: do not use floats for constantsMarton Balint2016-03-151-11/+11
| | | | | | | | | | | | | | | | This may improve the precision of the fixed point encoder/decoder for some compilers and architectures. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Marton Balint <cus@passwd.hu>

| | | | | | | | | | | | | | | | | | | | Commit 96786a12f6df26990bbe7c0ca4592b3731724469 makes runtime initialization cheap. Tested with FATE, with/without --enable-hardcoded-tables. Reviewed-by: Rostislav Pehlivanov <atomnuker@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>

| | | | | | | | | | | | | | AAC-Fixed decoder segfaulted. This commit makes the aac encoder and decoder init the table twice in case of transcoding again. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

* | aacenc: make threadsafeRostislav Pehlivanov2015-11-271-0/+3
| | | | | | | | | | | | | | | | Since the ff_aac_tableinit() can be called by both the encoder and the decoder (in case of transcoding) this commit shares the AVOnce variable to prevent this. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

* | aac: move the TNS tables from aacdectab to the shared aactabRostislav Pehlivanov2015-08-291-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | This commit simply moves the TNS tables to a more appropriate aactab.h since then they can be accessed by both the decoder and encoder. The encoder _shouldn't_ normally need the tables since the specs describe a specific quantization process, but the exact reason for this can be seen in the TNS commit following.

* AAC: Compress codebook tables and optimise sign bit handlingMåns Rullgård2010-01-131-0/+2
| | | | | | | | | | | | | | | | | | The codebooks each consist of small number of values repeated in groups of 2 or 4. Storing the codebooks as a packed list of 2- or 4-bit indexes into a table reduces their size substantially (from 7.5k to 1.5k), resulting in less cache pressure. For the band types with sign bits in the bitstream, storing the number and position of non-zero codebook values using a few bits avoids multiple get_bits() calls and floating-point comparisons which gcc handles miserably. Some float/int type punning also avoids gcc brain damage. Overall speedup 20-35% on Cortex-A8, 20% on Core i7. Originally committed as revision 21188 to svn://svn.ffmpeg.org/ffmpeg/trunk
