* avcodec/simple_idct10: improve precisionChristophe Gisquet2015-10-13
| | | | | | | | | | | 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.

* dnxhddec: use dequantization formula from specsChristophe Gisquet2015-10-02
| | | | | | | | | 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.
