* | checkasm/x86: Correctly handle variadic functionsHenrik Gramner2015-09-27
| | | | | | | | | | | | | | | | The System V ABI on x86-64 specifies that the al register contains an upper bound of the number of arguments passed in vector registers when calling variadic functions, so we aren't allowed to clobber it. checkasm_fail_func() is a variadic function so also zero al before calling it.

* | checkasm: Use a self-balancing treeHenrik Gramner2015-09-26
| | | | | | | | | | | | | | | | | | | | | | | | Tested functions are internally kept in a binary search tree for efficient lookups. The downside of the current implementation is that the tree quickly becomes unbalanced which causes an unneccessary amount of comparisons between nodes. Improve this by changing the tree into a self-balancing left-leaning red-black tree with a worst case lookup/insertion time complexity of O(log n). Significantly reduces the recursion depth and makes the tests run around 10% faster overall. The relative performance improvement compared to the existing non-balanced tree will also most likely increase as more tests are added.

* | AAC encoder: tweak PNS usage to be more aggressiveClaudio Freire2015-09-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch tweaks search_for_pns to be both more aggressive and more careful when applying PNS. On the one side, it will again try to use PNS on zero (or effectively zero) bands. For this, both zeroes and band_type have to be checked (some ZERO bands aren't marked in zeroes). On the other side, a more accurate rate-distortion measure avoids using PNS where it would cause audible distortion. Also fixed a small bug in the computation of freq that caused PNS usage on low-frequency bands during 8-short windows. This allows re-enabling PNS during 8-short.

* | AAC encoder: tweak rate-distortion logicClaudio Freire2015-09-23
| | | | | | | | | | | | | | | | | | | | | | | | This patch modifies the encode frame function to retry encoding the frame when the resulting bit count is too far off target, but only adjusting lambda in small, incremental step. It also makes the logic more conservative - otherwise it will contend with bit reservoir-related variations in bit allocation, and result in artifacts when frame have to be truncated (usually at high bit rates transitioning from low complexity to high complexity).

* | checkasm: add VP9 loopfilter tests.Ronald S. Bultje2015-09-20
| | | | | | | | | | | | | | The randomize_buffer() implementation assures that "most of the time", we'll do a good mix of wide16/wide8/hev/regular/no filters for complete code coverage. However, this is not mathematically assured because that would make the code either much more complex, or much less random.

* | AAC encoder: refactor to resynchronize MIPS portClaudio Freire2015-09-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch refactors the AAC coders to reuse code between the MIPS port and the regular, portable C code. There were two main functions that had to use hand-optimized versions of quantization code: - search_for_quantizers_twoloop - codebook_trellis_rate Those two were split into their own template header files so they can be inlined inside both the MIPS port and the generic code. In each context, they'll link to their specialized implementations, and thus be optimized by the compiler. This approach I believe is better than maintaining several copies of each function. As past experience has proven, having to keep those in sync was error prone. In this way, they will remain in sync by default. Also, an implementation of the dequantized output argument for the optimized quantize_and_encode functions is included in the patch. While the current implementation of search_for_pred still isn't using it, future iterations of main prediction probably will. It should not imply any measurable performance hit while not being used.

* | aaccoder: tweak PNS implementation furtherRostislav Pehlivanov2015-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes a few things about the noise substitution logic: - Brings back the quantization factor (reduced to 3) during scalefactor index calculations. - Rejects any zeroed bands. They should be inaudiable and it's a waste transmitting the scalefactor indices for these. - Uses swb_offsets instead of incrementing a 'start' with every window group size. - Rejects all PNS during short windows. Overall improves quality. There was a plan to use the lfg system to create the random numbers instead of using whatever the decoder uses but for now this works fine. Entropy is far from important here. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

* | aaccoder: add frequency scaling and quantization correction for PNSRostislav Pehlivanov2015-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit once again improves the PNS implementation by scaling the thresholds with frequency. The thresholds get looser as the frequency increases since higher frequencies are basically noise to human ears. Also, this introduces quantization error correction for PNS. Should the error be too much, no PNS will be used. The energy_ratio is used to regulate the actual encoded PNS energy: if the generated PNS energy is higher than the energy from the psy system, energy_ratio is used to correct it so that hopefully once requantized and transmitted the value in the decoder will be closer to what the encoder has.

* | aacenc_is: take absolute coefficient value upon energy calculationsRostislav Pehlivanov2015-09-06
| | | | | | | | | | | | | | | | | | | | | | 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.
