vp9: add some missing includes mostly: <file>.c should include <file>.h silences missing prototype warnings Change-Id: Ic05ec32c6f7b2224b78825904d96d73aacad6000 2015-05-15 05:21:01 +02:00			`#include "vp9/common/vp9_enums.h"`

vp9_ethread: modify VP9_COMP structure This patch modified struct VP9_COMP. Created a struct ThreadData to include data that need to be copied for each thread. In multiple thread case, one thread processes one tile. all threads share one copy of VP9_COMP, (refer to VP9_COMP cpi in the code) but each thread has its own copy of ThreadData, (refer to ThreadData td in the code). Therefore, within the scope of encode_tiles(), both cpi and td need to be passed as function parameters. In single thread case, the FRAME_COUNTS pointer in ThreadData points to "counts" in VP9_COMMON. Change-Id: Ib37908b2d8e2c0f4f9c18f38017df5ce60e8b13e 2014-11-21 20:11:06 +01:00			`struct macroblock;`

Substantial restructuring of AQ mode 2. The restructure moves the decision into the rd pick modes loop and makes a decision based at the 16x16 block level instead of only the 64x64 level. This gives finer granularity and better visual results on the clips I have tested. Metrics results are worse than the old AQ2 especially for PSNR and this mode now falls between AQ0 and AQ1 in terms of visual impact and metrics results. Further tuning of this to follow. It should be noted that if there are multiple iterations of the recode loop the segment for a MB could change in each loop if the previous loop causes a change in the complexity / variance bin of the block. Also where a block gets a delta Q this will alter the rd multiplier for this block in subsequent recode iterations and frames where the segmentation is applied.
