Make encoder buffer allocation dynamic Frame buffers are now allocated dynamically on-demand. Entries in the reference frame map, cm->ref_frame_map, may now be set to -1 (INVALID_IDX) to indicate that there is not a valid reference buffer in that "slot". All slots in the reference frame map are now initialized to the empty state (-1) and each buffer is initialized to have a reference count of 0. Change-Id: Id1afe98de98db4ae8b2dfefed7889c3b28c68582

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.

int vp9_alloc_context_buffers(struct VP9Common *cm, int width, int height);
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.

Try again to merge branch 'frame-parallel' into master branch. In frame parallel decode, libvpx decoder decodes several frames on all cpus in parallel fashion. If not being flushed, it will only return frame when all the cpus are busy. If getting flushed, it will return all the frames in the decoder. Compare with current serial decode mode in which libvpx decoder is idle between decode calls, libvpx decoder is busy between decode calls. Current frame parallel decode will only speed up the decoding for frame parallel encoded videos. For non frame parallel encoded videos, frame parallel decode is slower than serial decode due to lack of loopfilter worker thread. There are still some known issues that need to be addressed. For example: decode frame parallel videos with segmentation enabled is not right sometimes. * frame-parallel: Add error handling for frame parallel decode and unit test for that. Fix a bug in frame parallel decode and add a unit test for that. Add two test vectors to test frame parallel decode. Add key frame seeking to webmdec and webm_video_source. Implement frame parallel decode for VP9. Increase the thread test range to cover 5, 6, 7, 8 threads. Fix a bug in adding frame parallel unit test. Add VP9 frame-parallel unit test. Manually pick "Make the api behavior conform to api spec." from master branch. Move vp9_dec_build_inter_predictors_* to decoder folder. Add segmentation map array for current and last frame segmentation. Include the right header for VP9 worker thread. Move vp9_thread.* to common. ctrl_get_reference does not need user_priv. Seperate the frame buffers from VP9 encoder/decoder structure.

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).
