2016-11-22vp9,read_inter_block_mode_info: quiet msan warningJames Zern
best_sub8x8[1] won't be used meaningfully when is_compound is false, but may trigger an msan warning as the value is copied around and later clamped. BUG=667044 Change-Id: Icc24c3b72cdb550bebea44d4aaa4ff8bf3fbab56
2016-11-01vp9,tile_worker_hook: correctly set jmp targetJames Zern
vp9_init_macroblockd() resets the error_info to cm's global copy; this needs to be set to the thread-level target to avoid jumping to the incorrect stack, resulting in hang or crash. broken since: 1f4a6c8 vp9/tile_worker_hook: add multiple tile decoding includes v1.5.0, v1.6.0 BUG=629481 Change-Id: Icbf1696b25ba8c479e845fbf227b3c3ca73542f5

2016-07-06Remove decode asserts from better-hw-compatibilityDebargha Mukherjee
Safer to have the decoder operate normally and have better-hw-compatibility only implement encoding changes. Fixes some test failures. Change-Id: I0dd70d002e4e893992f0cd59774b9363e6f7fe76
2016-07-01Make set_reference control API work in VP9Yunqing Wang
Moved the API patch from NextGenv2. An example was included. To try it, for example, run the following command: $ examples/vpx_cx_set_ref vp9 352 288 in.yuv out.ivf 4 30 Change-Id: I4cf8f23b86d7ebd85ffd2630dcfbd799c0b88101
2016-06-21Add a hardware compatibility featurehui su
This commit adds an encoder workaround to support better compatibility with a non-compliant hardware vp9 profile 2 decoder. The known issue with this decoder is: The decoder assumes a wrong value, 127 instead of the correct value of 511 and 2047, for any assumed top-left corner pixel in UV planes for 10 and 12 bit, respectively. Such assumed top-left corner pixel is used for INTRA prediction when a real decoded/reconstructed pixel is not avalable, e.g. when it is located inside the row above the top row or inside the column left to the leftest column of a video image.

The inlining mirrors what was done with the low bit depth inter_predictor. And the new highbd_inter_predictor name is more consistent with other high bit depth functions. Change-Id: I96437f745759aeec6260c6e39a974bf36f1c211c

Prior to this patch, read_inter_block_mode_info() would find the nearmv and nearestmv for all modes. Now it does not search for ZEROMV modes and breaks out early for NEARMV and NEWMV modes. Change-Id: Ifa7b1eaf58bb03b9c7792ea5012fef477527d0fd
