* x86: simple_idct: 12bits versionsChristophe Gisquet2015-10-133-2/+42
| | | | | | | | | | | | | | | | | | | | | | On 12 frames of a 444p 12 bits DNxHR sequence, _put function: C: 78902 decicycles in idct, 262071 runs, 73 skips avx: 32478 decicycles in idct, 262045 runs, 99 skips Difference between the 2: stddev: 0.39 PSNR:104.47 MAXDIFF: 2 This is unavoidable and due to the scale factors used in the x86 version, which cannot match the C ones. In addition, the trick of adding an initial bias to the input of a pass can overflow, as the input coefficients are already 15bits, which is the maximum this function can handle. Overall, however, the omse on 12 bits samples goes from 0.16916 to 0.16883. Reducing rowshift by 1 improves to 0.0908, but causes overflows. Signed-off-by: Michael Niedermayer <[email protected]>
* x86: simple_idct(_put): 10bits versionsChristophe Gisquet2015-10-136-33/+136
| | | | | | | | | | | | | | | | | Modeled from the prores version. Clips to [0;1023] and is bitexact. Bitexactness requires to add offsets in different places compared to prores or C, and makes the function approximately 2% slower. For 16 frames of a DNxHD 4:2:2 10bits test sequence: C: 60861 decicycles in idct, 1048205 runs, 371 skips sse2: 27567 decicycles in idct, 1048216 runs, 360 skips avx: 26272 decicycles in idct, 1048171 runs, 405 skips The add version is not implemented, so the corresponding dsp function is set to NULL to make it clear in a code executing it.

* x86: simple_idct10_template: fix overflow in passChristophe Gisquet2015-10-132-5/+16
| | | | | | | | | | | | | | When the input of a pass has 15 or 16 bits of precision (in particular the column pass), the addition of a bias to W4 may lead to overflows in the input to pmaddwd. This requires postponing the adding of the bias to after the first butterfly. To do so, the fact that m15, unused although zeroed, is exploited. In case the pass is safe, an address can be directly used, and the number of xmm regs can be decreased. Otherwise, the 32bits bias is loaded into it.

* avcodec/simple_idct10: improve precisionChristophe Gisquet2015-10-136-20/+42
| | | | | | | | | | | omse goes from 0.03060703 (which fails for dct-test) to 0.01663750. This also actually improve the error of decoding the sample generated by fate-vsynth3-dnxhd1080i-10bit using simple_idct10 to FAANI, which goes (when resampled to yuv422p) from: stddev: 0.06 PSNR: 72.28 MAXDIFF: 1 to identical.

* aacenc: add support for changing options based on a profileRostislav Pehlivanov2015-10-125-51/+137
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | 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.

* AAC encoder: memoize quantize_band_costClaudio Freire2015-10-127-4/+86
| | | | | | | | | | 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.

| | | | | | | | Intermediate results can indeed violate SF delta. Instead of asserting there, just make the code safe, and assert on the final result. Also re-clamp SFs more often in short windows (which tend to violate the restriction when encoding the switch from one window to the other)

* AAC encoder: Extensive improvementsClaudio Freire2015-10-1118-261/+1276
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This finalizes merging of the work in the patches in ticket #2686. Improvements to twoloop and RC logic are extensive. The non-exhaustive list of twoloop improvments includes: - Tweaks to distortion limits on the RD optimization phase of twoloop - Deeper search in twoloop - PNS information marking to let twoloop decide when to use it (turned out having the decision made separately wasn't working) - Tonal band detection and priorization - Better band energy conservation rules - Strict hole avoidance For rate control: - Use psymodel's bit allocation to allow proper use of the bit reservoir. Don't work against the bit reservoir by moving lambda in the opposite direction when psymodel decides to allocate more/less bits to a frame. - Retry the encode if the effective rate lies outside a reasonable margin of psymodel's allocation or the selected ABR. - Log average lambda at the end. Useful info for everyone, but especially for tuning of the various encoder constants that relate to lambda feedback. Psy: - Do not apply lowpass with a FIR filter, instead just let the coder zero bands above the cutoff. The FIR filter induces group delay, and while zeroing bands causes ripple, it's lost in the quantization noise. - Experimental VBR bit allocation code - Tweak automatic lowpass filter threshold to maximize audio bandwidth at all bitrates while still providing acceptable, stable quality. I/S: - Phase decision fixes. Unrelated to #2686, but the bugs only surfaced when the merge was finalized. Measure I/S band energy accounting for phase, and prevent I/S and M/S from being applied both. PNS: - Avoid marking short bands with PNS when they're part of a window group in which there's a large variation of energy from one window to the next. PNS can't preserve those and the effect is extremely noticeable. M/S: - Implement BMLD protection similar to the specified in ISO-IEC/13818:7-2003, Appendix C Section 6.1. Since M/S decision doesn't conform to section 6.1, a different method had to be implemented, but should provide equivalent protection. - Move the decision logic closer to the method specified in ISO-IEC/13818:7-2003, Appendix C Section 6.1. Specifically, make sure M/S needs less bits than dual stereo. - Don't apply M/S in bands that are using I/S Now, this of course needed adjustments in the compare targets and fuzz factors of the AAC encoder's fate tests, but if wondering why the targets go up (more distortion), consider the previous coder was using too many bits on LF content (far more than required by psy), and thus those signals will now be more distorted, not less. The extra distortion isn't audible though, I carried extensive ABX testing to make sure. A very similar patch was also extensively tested by Kamendo2 in the context of #2686.
