2014-09-19Remove mi_grid_* structures.hkuang
mi_grid_* are arrays of pointer to pointer. They save the pointers that point to the MIs in cm->mi. But they are unnecessary and complicated. The original goal was to remove MODE_INFO_t copy. But with an extra MODE_INFO_t pointer inside MODE_INFO_t, same goal could be achieved. This commit totally removes the mi_grid_* structures. But there are still many dummy MODE_INFO_t inside cm->mi which are a waste of memory. Next commit will do on-demand MODE_INFO_t allocation in order to save these memories.

2014-09-11Adds high bitdepth transform functions and testsDeb Mukherjee
Adds various high bitdepth transform functions and tests. Much of the changes are related to using typedefs tran_low_t and tran_high_t for the final transform cofficients and intermediate stages of the transform computation respectively rather than fixed types int16_t/int. When vp9_highbitdepth configure flag is off, these map tp int16_t/int32_t, but when the flag is on, they map to int32_t/int64_t to make space for needed extra precision.

2014-09-04vp9: correct context buffer resize checkJames Zern
allocations within vp9_alloc_context_buffers() rely on mi_rows/mi_cols individually, use those to determine whether to realloc rather than stride and stride * rows. this fixes a crash with some fuzzed files for invalid accesses into last_frame_seg_map and above_context.

2014-07-28Fix reference frame size restrictions.Jim Bankoski
The issue was introduced by commit g9f37d14 with adding explicit restrictions on reference-frame scale factors. The restriction is checked against aligned-by-8 frame dimensions, not against original ones. So, for example, frame of 35×35 actually can refer to frame of 70×70, but the new check won't allow this. It will compare 35 vs 72 (not 70), so 2x downscale limit will be exceeded. Change-Id: Ic663693034440f64ac8312cbff9e1e773a921060
2014-07-25Merge "Fix allocation of context buffers on frame resize"Yaowu Xu
2014-07-24Changed validation of reference frame sizeYaowu Xu
A previous change, https://gerrit.chromium.org/gerrit/#/c/70632, introduced a size validation for reference frames to insuare the input stream is a valid VP9 stream. However, the logic requiring all reference frames have valid size turned out to be too strict. In this commit, we modify the validation to require one of the reference frame has valid dimension. In addition, the decoder reports error whenever it detects the use of reference frame with invalid scalig ratio. Change-Id: If8efc312244087556cfe00f1fcbdff811268ebad
2014-07-24Fix allocation of context buffers on frame resizeAdrian Grange
The patch: https://gerrit.chromium.org/gerrit/#/c/70814/ changed the test that determined whether the context frame buffers needed to be reallocated or not. The code checked for a change in total frame area to signal the need to reallocate context buffers. However, the above_context buffer needs to be resized i:xf only the width of the frame has increased. Change-Id: Ib89d75651af252908144cf662578d84f16cf30e6
