2013-03-26Add an in-loop deringing experimentJohn Koleszar
Adds a per-frame, strength adjustable, in loop deringing filter. Uses the existing vp9_post_proc_down_and_across 5 tap thresholded blur code, with a brute force search for the threshold. Results almost strictly positive on the YT HD set, either having no effect or helping PSNR in the range of 1-3% (overall average 0.8%). Results more mixed for the CIF set, (-0.5 min, 1.4 max, 0.1 avg). This has an almost strictly negative impact to SSIM, so examining a different filter or a more balanced search heuristic is in order. Other test set results pending. Change-Id: I5ca6ee8fe292dfa3f2eab7f65332423fa1710b58
2013-03-13Fix pulsing issue with scalingJohn Koleszar
Updates the YV12_BUFFER_CONFIG structure to be crop-aware. The exiting width/height parameters are left unchanged, storing the width and height algined to a 16 byte boundary. The cropped dimensions are added as new fields. This fixes a nasty visual pulse when switching between scaled and unscaled frame dimensions due to a mismatch between the scaling ratio and the 16-byte aligned sizes.

2013-02-08Avoid allocating memory when resizing framesJohn Koleszar
As long as the new frame is smaller than the size that was originally allocated, we don't need to free and reallocate the memory allocated. Instead, do the allocation on the size of the first frame. We could make this passed in from the application instead, if we wanted to support external upscaling. Change-Id: I204d17a130728bbd91155bb4bd863a99bb99b038

2013-01-07minor loop filter refactoring and cleanupYaowu Xu
This commit did a couple of minor cleanup/refactoring to prepare for futher loop filter experiments. It merged y_only version of loop filter function into the regular one, which makes sure that same logic is used for functions for picking level and for actual loop filtering.

Various fixups to resolve issues when building vp9-preview under the more stringent checks placed on the experimental branch. Change-Id: I21749de83552e1e75c799003f849e6a0f1a35b07
2012-12-18Use standard integer types for pixel values and coefficients.Ronald S. Bultje
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). Change-Id: I3619cd9abf106c3742eccc2e2f5e89a62774f7da

2012-12-05Begin to refactor vpx_scale usage in VP9Johann
Only declare the functions in vpx_scale RTCD and include the relevant header. Remove unused files and functions in vpx_scale to avoid wasting time renaming. vpx_scale/win32/scaleopt.c contains functions which have not been called in a long time but are potentially optimized. The 'vp8' functions have not been renamed yet. That is for after the cleanup. Change-Id: I2c325a101d60fa9d27e7dfcd5b52a864b4a1e09c
