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).

Adds new Directional Intra prediction modes. Adds 6 directional intra predictiom modes for 16x16 and 8x8 blocks. Change-Id: I25eccc0836f28d8d74922e4e9231568a648b47d1 2012-05-15 01:21:01 +02:00
a few clean-ups 1. remove prediction mode conversion 2. unified bmode, same for key and non-key frame 3. set I4X4_PRED count for pdf to 0, as I4X4_PRED is no longer coded ever. It is determined by ref_frame and block partition Change-Id: If5b282957c24339b241acdb9f2afef85658fe47d 2013-05-25 01:13:54 +02:00			`MB_PREDICTION_MODE vp9_find_dominant_direction(uint8_t *ptr,`

changes intra coding to be based on txfm block This commit changed the encoding and decoding of intra blocks to be based on transform block. In each prediction block, the intra coding iterates thorough each transform block based on raster scan order. This commit also fixed a bug in D135 prediction code. TODO next: The RD mode/txfm_size selection should take this into account when computing RD values. Change-Id: I6d1be2faa4c4948a52e830b6a9a84a6b2b6850f6 2013-05-17 21:50:40 +02:00			`int bwl_in,`

Make intra predictor reference buffer configurable This commit enables configurable reference buffer pointer for intra predictor. This allows later removal of spatial dependency between blocks inside a 64x64 superblock in the rate-distortion optimization loop.
