* | aacenc: implement Intensity Stereo encoding supportRostislav Pehlivanov2015-07-053-3/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit implements intensity stereo coding support to the native aac encoder. This is a way to increase the efficiency of the encoder by zeroing the right channel's spectral coefficients (in a channel pair) and rederiving them in the decoder using information from the scalefactor indices of special band types. This commit confomrs to the official ISO 13818-7 specifications, although due to their ambiguity certain deviations have been taken to ensure maximum sound quality. This commit has been extensively tested and has shown to not result in audiable audio artifacts unless in extreme cases. This commit also adds an option, aac_is, which has the value of 0 by default. Intensity Stereo is part of the scalable aac profile and is thus non-default. The way IS coding works is that it rederives the right channel's spectral coefficients from the left channel via the scalefactor index values left in the right channel. Since an entire band's spectral coefficients do not need to be coded, the encoder's efficiency jumps up and it unzeroes some high frequency values which it previously did not have enough bits to encode. That way less information is lost than the information lost by rederiving the spectral coefficients with some error. This is why the filesize of files encoded with IS do not decrease significantly. Users wishing that IS coding should reduce filesize are expected to reduce their encoding bitrates appropriately. This is V2 of the commit. The old version did not mark ms_mask as 0 since M/S and IS coding are incompactible, which resulted in distortions with M/S coding enabled. This version also improves phase detection by measuring it for every spectral coefficient in the band and using a simple majority rule to determine whether the coefficients are in or out of phase. Also, the energy values per spectral coefficient were changed as to reflect the official specifications.

* | aacenc: add support for coding of IS spectral coefficientsRostislav Pehlivanov2015-07-051-10/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds support for the coding of intensity stereo spectral coefficients. It also fixes the Mid/Side coding of band_types higher than RESERVED_BT (M/S must not be applied to their spectral coefficients, but marking M/S as present in encode_ms_info() is okay). Much of the changes here were taken from the decoder and inverted. This commit does not change the functionality of the decoder as the previous patch in this series zeroes ms_mask and is_mask.

* | aaccoder: add a new perceptual noise substitution implementationRostislav Pehlivanov2015-07-053-1/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit finalizes the PNS implementation previously added to the encoder by moving it to a seperate function search_for_pns() and thus making it coder-generic. This new implementation makes use of the spread field of the psy bands and the lambda quality feedback paremeter. The spread of the spectrum in a band prevents PNS from being used excessively and thus preserve more phase information in high frequencies. The lambda parameter allows the number of PNS-marked bands to vary based on the lambda parameter and the amount of bits available, making better choices on which bands are to be marked as noise. Comparisons with the previous PNS implementation can be found here: https://trac.ffmpeg.org/attachment/wiki/Encode/AAC/ This is V2 of the patch, the changes from the previous version being that this version uses the new band->spread metric from aacpsy and normalizes the energy using the group size. These changes were suggested by Claudio Freire on the mailing list. Another change is the use of lambda to alter the frequency threshold. This change makes the actual threshold frequencies vary between +-2Khz of what's specified, depending on frame encoding performance.

| | | | | | | | | | | | | | | | | | | | | | This commit enables the function added with commit 7c10b87 and uses that new function for setting any special scalefactor indices. This commit does not change the behaviour of the encoder since no bands are being marked as either NOISE_BT(due to the previous PNS implementation removed in the previous commit) or INTENSITY_BT2/INTENSITY_BT.

* | avcodec/nvenc: Add support for H.264 High 444 Predictive encodingPhilip Langdale2015-07-051-3/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer versions of the nvenc hardware support The High 444 Predictive profile of H.264, and can also do lossless encoding under this profile if desired. This change introduces support for the profile, and exposes the appropriate presets for requesting lossless encoding. I tested lossless by generating a baseline sample with testsrc converted to raw yuv444p, then encoded the sample with nvenc, then did a framemd5 comparision of both the raw video and the nvenc encode. The framemd5 reports were identical. Signed-off-by: Philip Langdale <philipl@overt.org> Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

The spread[w+g] used before this patch behaved more like a low-pass filter for PNS band_types, which could mistakingly mark some low frequency bands as noise.
