Moving bits from compressed header to uncompressed one. Bits moved: refresh_frame_flags, active_ref_idx[], ref_frame_sign_bias[], allow_high_precision_mv, mcomp_filter_type, ref_pred_probs[]. Derf results: +0.040% Change-Id: I011f43c7eac0371d533b255fd99aee5ed75b85a5 2013-06-06 05:56:37 +02:00
Allocate buffers based on correct chroma format The encoder currently allocates frame buffers before it establishes what the chroma sub-sampling factor is, always allocating based on the 4:4:4 format. This patch detects the chroma format as early as possible allowing the encoder to allocate buffers of the correct size. Future patches will change the encoder to allocate frame buffers on demand to further reduce the memory profile of the encoder and rationalize the buffer management in the encoder and decoder.

Modified frame buffer handling This patch is the first step toward simplifying the frame buffer handling. The final goal is to have a common frame buffer handling framework for both encoder and decoder that incorporates the existing ability to use externally allocated memory.

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).
