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).

Adjust style to match Google Coding Style a little more closely. Most of these were picked up by jenkins in the commit that changed the vp8 namespace to vp9 in common/. Change-Id: I5cbd56ffc753b92ef805133cda6acc1713a13878 2012-10-31 16:09:17 -07:00
General code cleanup. Removing redundant code, lower case variable names, better indentation, better parameter names, adding const to readonly parameters.

Refactor lookahead ring buffer This patch cleans up the source buffer storage and copy mechanism to allow access through a standard push/pop/peek interface. This approach also avoids an extra copy in the case where the source is not a multiple of 16, fixing issue #102.

Copy less when active map is in use When active map is specified and the current frame is not a key frame, golden frame nor a altref frame then copy only those active regions. This significantly reduces encoding time by as much as 19% on the test system where realtime encoding is used. This is particularly useful when the frame size is large (e.g. 2560x1600) and there's only a few action macroblocks.
