Fix pulsing issue with scaling Updates the YV12_BUFFER_CONFIG structure to be crop-aware. The exiting width/height parameters are left unchanged, storing the width and height algined to a 16 byte boundary. The cropped dimensions are added as new fields. This fixes a nasty visual pulse when switching between scaled and unscaled frame dimensions due to a mismatch between the scaling ratio and the 16-byte aligned sizes.

Instead, do the allocation on the size of the first frame. We could make this passed in from the application instead, if we wanted to support external upscaling.

Implement error tracking in the decoder A new vpx_codec_control called VP8D_GET_FRAME_CORRUPTED. The output from the function is non-zero if the last decoded frame contains corruption due to packet losses. The decoder is also modified to accept encoded frames of zero length. A zero length frame indicates to the decoder that one or more frames have been completely lost. This will mark the last decoded reference buffer as corrupted. The data pointer can be NULL if the length is zero. Change-Id: Ic5902c785a281c6e05329deea958554b7a6c75ce

Subsampling aware allocs and bitstream Make framebuffer allocations according to the chroma subsamping factors in use. A bit is placed in the raw part of the frame header for each of the two subsampling factors. This will be moved in a future commit to make them part of the TBD feature set bits, probably only set on keyframes, etc. Change-Id: I59ed38d3a3c0d4af3c7c277617de28d04a001853
