A fix in MV_REF experiment This fix ensures that the forward prob update is not turned off for motion vectors. Change-Id: I0b63c9401155926763c6294df6cca68b32bac340 2012-11-09 19:52:08 +01:00			`void vp9_write_nmv_probs(VP9_COMP* const, int usehp, vp9_writer* const);`
Combining integer and fractional parts of mvs for entropy coding. Combining encode_nmv_component with encode_nmv_component_fp and read_nmv_component with read_nmv_component_fp. Bitstream is slightly changed (only the order of bits), here are the results on test sets: stdhd: +0.047, yt: -0.038, derf: +0.001, hd: -0.011.

New motion vector entropy coding Adds a new experiment with redesigned/refactored motion vector entropy coding. The patch also takes a first step towards separating the integer and fractional pel components of a MV. However the fractional pel encoding still depends on the integer pel part and so they are not fully independent. Further experiments are in progress to see how much they can be decoupled without affecting performance. All components including entropy coding/decoding, costing for MV search, forward updates and backward updates to probability tables, have been implemented. Results so far: derf: +0.19% std-hd: +0.28% yt: +0.80% hd: +1.15% Patch: Simplifies the fractional pel models: derf: +0.284% std-hd: +0.289% yt: +0.849% hd: +1.254% Patch: Some changes in the models, rebased. derf: +0.330% std-hd: +0.306% yt: +0.816% hd: +1.225% Change-Id: I646b3c48f3587f4cc909639b78c3798da6402678 2012-07-26 22:42:07 +02:00			`int *mvcost[2],`
silent a lot of MSVC compiler warnings there are still a couple type of warning left, which are related to double constants assigned to float type. As those would be addressed by the conversion of transforms into integer version. This commit has left those un-dealt with.

Use standard integer types for pixel values and coefficients. For coefficients, use int16_t (instead of short); for pixel values in 16-bit intermediates, use uint16_t (instead of unsigned short); for all others, use uint8_t (instead of unsigned char).
