* | fate: add 1 and 15BPP rawvideo in avi testsMichael Niedermayer2016-01-22
| | | | | | | | Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* | fate: add 10bits YUV4:2:2 dnxhd testChristophe Gisquet2015-10-13
| | | | | | | | | | | | | | It was useful to (accidentally?) spot an overflow in the column pass of the x86 simple_idct10 implementation. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* | 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.

| * h261: Signal freeze picture release for intra framesStian Selnes2015-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Freeze picture release should be set to 1 when we're responding to a fast update request. For simplicity we set it for all intra frames, including those that starts a GOP. Fixes issue where Tandberg MXP1700 does not recover from packet loss state since it's waiting for the freeze picture relase indication.

| * h261: Set 'still image mode off' in picture headerStian Selnes2015-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ref H.261 recommendation section 4.2.1.3, setting the still image flag to 1 disables still image mode. Some decoders require this in order to decode the bitstream as normal video. Fixes H.261 calls to Cisco E20. Also, reserved (aka spare) bits should be set to 1 unless specified otherwise.

| | | | | | | | | | | | | | | | | | | | | | | | Outputting DNxHD into .mov containers 'corrupts' following atoms until end of stsd ffmpeg and qtdump could not decode pasp/colr atoms in the files made by ffmpeg, when outputting DNxHD due to the incorrect padding placement.

| | | | | | | | | | | | | | | | | | | | Avid prefers mpeg range [16-235] by default this change brings ffmpeg into line with that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, a Laplace distribution is more typical of the residuals encoded, but for noisy input, it's both better and simpler to be safe and use a 1/d^2 distribution. Second hunk could use some renormalization but it has effectively little impact.
