Christophe Gisquet	2fd14dd8eb	avcodec/simple_idct10: improve precision 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.

Christophe Gisquet	c7e14a279f	dnxhddec: use dequantization formula from specs The current one, while correct, does not yield the best possible results. The specificiations suggest another formula, which results in quality gains in the decoded output from fate tests. This justifies changing said formula.

Joseph Artsimovich	bfe1cd80eb	dnxhddata: Fix 10-bit DNxHD quant matrices Convert them to zigzag order, as the rest of them are. When I was adding support for 10-bit DNxHD, I just copy-pasted the missing quant matrices from the spec. Now it turns out the existing matrices in dnxhddata.c were in zigzag order. This resulted in wrong quantization for 10-bit DNxHD. The attached patch fixes the problem by converting 10-bit quant matrices to zigzag order.

Michael Niedermayer	42801505cd	tests: Add vsynth2 which uses the new reference.pnm The file is already present in git and by using it we can perform more tests without the need of fate samples Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	ed49b142bb	tests: Rename vsynth2 to vsynth_lena This avoids confusion with a growing number of vsynth tests Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Reinhard Tartler	8895bf7b78	Replace lena.pnm The new reference.pnm is a freely licensed replacement. The photo has been taken by Reinhard Tartler on August 28 2014, and is licensed under the expat license as stated at http://www.jclark.com/xml/copying.txt	10 years ago
Michael Niedermayer	cca2772e16	avcodec/simple_idct_template: change the idct coefficients so that they match the x86 code no changes in either standard deviation or PSNR is seen in any of the changed fate cases MSE changes from 0.05012422 to 0.04890000 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
