Claudio Freire	b629c67ddf	AAC encoder: memoize quantize_band_cost The bulk of calls to quantize_band_cost are replaced by a call to a version that memoizes, greatly improving performance, since during coefficient search there is a great deal of repeat work. Memoization cannot always be applied, so do this in a different function, and leave the original as-is.	9 years ago
Andreas Cadhalpun	ec0275843d	avcodec: remove leftover iff_byterun1 decoder It was merged with the iff_ilbm decoder in commit `929a24efff`. Define AV_CODEC_ID_IFF_BYTERUN1 as AV_CODEC_ID_IFF_ILBM for API compatibility. Reviewed-by: Ronald S.

Rostislav Pehlivanov	76b81b10d9	aacenc: implement the complete AAC-Main profile This commit finalizes AAC-Main profile encoding support by implementing all mandatory and optional tools available in the specifications and current decoders. The AAC-Main profile reqires that prediction support be present (although decoders don't require it to be enabled) for an encoder to be deemed capable of AAC-Main encoding, as well as TNS, PNS and IS, all of which were implemented with previous commits or earlier of this year. Users are encouraged to test the new functionality using either -profile:a aac_main or -aac_pred 1, the former of which will enable the prediction option by default and the latter will change the profile to AAC-Main. No other options shall be changed by enabling either, it's currently up to the users to decide what's best. The current implementation works best using M/S and/or IS, so users are also welcome to enable both options and any other options (TNS, PNS) for maximum quality.

Rostislav Pehlivanov	a1c487e921	aacenc_tns: implement temporal noise shaping This commit implements temporal noise shaping support in the encoder, along with an -aac_tns option to toggle it on or off (off by default for now). TNS will increase audio quality and reduce quantization noise by applying a multitap FIR filter across allowed coefficients and transmit side information to the decoder so it could create an inverse filter. Users are encouraged to test the new functionality by enabling -aac_tns 1 during encoding. No major bugs are observable at this time so after a while if no new problems appear and if the current implementation is deemed of high enough quality and stability it will be enabled by default, possibly at the same time the encoder has its experimental flag removed and becomes the standard aac encoder in ffmpeg.

Rostislav Pehlivanov	d1ca7142ac	aaccoder: move the Intensity Stereo implementation out This commit moves the intensity stereo implementation out from aaccoder and into a separate file. This was possible using the previous commits. This commit also drastically improves the IS implementation by making it phase invariant e.g. it will always choose the best possible phase regardless of whether M/S coding is on or most of the coefficients have identical phases. This also increases the quality and reduces any distortions introduced by enablind intensity stereo. Users are encouraged to test it out using the -aac_is 1 parameter as it has always been.

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.
