Rostislav Pehlivanov	e9299df7a6	aacenc: partially revert previous commits to set options via a profile It didn't work out because of the exceptions that needed to be made for the "-1" cases and was overall more confusing that just manually checking and setting options for each profile.	9 years ago
Rostislav Pehlivanov	0f4334df45	aacenc: add support for changing options based on a profile This commit adds the ability for a profile to set the default options, as well as for the user to override such options by simply stating them in the command line while still keeping the same profile, as long as those options are still permitted by the profile. Example: setting the profile to aac_low (the default) will turn PNS and IS on. They can be disabled by -aac_pns 0 and -aac_is 0, respectively. Turning on -aac_pred 1 will cause the profile to be elevated to aac_main, as long as no options forbidding aac_main have been entered (like AAC-LTP, which will be pushed soon). A useful feature is that by setting the profile to mpeg2_aac_low, all MPEG4 features will be disabled and if the user tries to enable them then the program will exit with an error. This profile is signalled with the same bitstream as aac_low (MPEG4) but some devices and decoders will fail if any MPEG4 features have been enabled.	9 years ago
Rostislav Pehlivanov	b3deaece87	aacenc: add support for encoding 7.1 channel audio This commit implements support for 7.1 channel audio. There's no more predefined bitstream channel mappings so going beyond 8 channels (and 7 channels exactly) will require programmable channel elements, which is already underway.	9 years ago

Claudio Freire	b01f3ddad3	AAC encoder: simplify and speed up find_min_book Trivial change to simplify the small but hot find_min_book function. The new form is easier to understand and faster.	9 years ago
Rostislav Pehlivanov	139c2f93fd	aacenctab: add tns_min_sfb[] to the encoder tables header Needed for following commits. Contains the starting sfb for every samplerate and window type. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	9 years ago

Rostislav Pehlivanov	c47c781e83	aacenc: Move local encoder specific tables to a separate file This commit moves any tables specific to the encoder from aacenc and aaccoder to a separate file called 'aacenctab.c/.h'. This was done as a clean up attempt as the encoder was filled with tables pasted in between functions which made it confusing to follow and track where each table and definition had been used. This commit solves this by simply exporting the smaller tables out to the aacenctab.h while the larger ones are compiled using aacenctab.c and are referenced from the header file.
