tab	fb135139fd	avformat: implement query_codec for the image2 muxer. Allows avformat_query_codec to be used to check for valid image2 encoders. Reuses the existing ff_guess_image2_codec ID table. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Rostislav Pehlivanov	1956cfbaed	aacenc_is: take absolute coefficient value upon energy calculations This was an oversight when the IS system was being first implemented. The ener01 part was largely a result of trial and error and the fact that the sum of coef0 and coef1 could result in a zero was overlooked. Once ener01 turns to zero it's used to divide the left channel energy which doesn't turn out so well as it fills IS[] with -nan's and inf's which in turn confused the quantize_band_cost.

Rostislav Pehlivanov	033e58941e	aaccoder: rewrite PNS implementation This commit rewrites the PNS implementation and significantly improves sonic quality. The previous implementation marked an incredibly big amount of SFBs to predict when there was no need for this and this resulted in quite a large amount of artifacts. Also the quantization was incorrect (av_clip(4+log2f(...))) which led to 3x the intensity for PNS values leading to even more artifacts. This commit rewrites the PNS search function and introduces a major change: the PNS values are synthesized and are compared to the current coefficients in addition to passing through the revised checks to see whether PNS can be used. This decreases distortions and makes the current PNS implementation mainly focused on replacing any low-power non-zero bands as well as adding any zeroed bands back. The current encoder's performance is enough (especially with IS) so PNS isn't really required except to fill in the occasional few bands as well as extend any zeroed high frequency, so this combination which is already enabled by default works to get as much quality as it can within the bits allowed.

Rostislav Pehlivanov	8848c8440e	aacenc_pred: disable PNS SFBs and disable right predictors with IS Since PNS generates coefficients it doesn't make sense to send the predicted ones as well. Also the specifications explicitly state to disable right channel IS predictors. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	9 years ago
Rostislav Pehlivanov	a71f7de95b	aacenc_is: ignore PNS band types It's better to trust that the coefficients generated will be closer than the coefficients derived, and the new PNS implementation makes sure that this happens. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	9 years ago
Rostislav Pehlivanov	b9b1fd1183	aaccoder: use roundf() instead of ceilf() The specifications explicitly state to use roundf() which also rounds half-integer values away from zero. This does fix a few IS artifacts. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	9 years ago
