2014-10-03Rework partition search skip schemeJingning Han
This commit enables the encoder to skip split partition search if the bigger block size has all non-zero quantized coefficients in low frequency area and the total rate cost is below a certain threshold. It logarithmatically scales the rate threshold according to the current block size. For speed 3, the compression performance loss: derf -0.093% stdhd -0.066% Local experiments show 4% - 20% encoding speed-up for speed 3. blue_sky_1080p, 1500 kbps 51051 b/f, 35.891 dB, 67236 ms -> 50554 b/f, 35.857 dB, 59270 ms (12% speed-up) old_town_cross_720p, 1500 kbps 14431 b/f, 36.249 dB, 57687 ms -> 14108 b/f, 36.172 dB, 46586 ms (19% speed-up) pedestrian_area_1080p, 1500 kbps 50812 b/f, 40.124 dB, 100439 ms -> 50755 b/f, 40.118 dB, 96549 ms (4% speed-up) mobile_calendar_720p, 1000 kbps 10352 b/f, 35.055 dB, 51837 ms -> 10172 b/f, 35.003 dB, 44076 ms (15% speed-up) Change-Id: I412e34db49060775b3b89ba1738522317c3239c8
2014-10-01High-bitdepth bugfixesDeb Mukherjee
Miscellaneous bug-fixes for high bitdepth functionality. With this patch, high bit-depth profiles become mostly functional, except for an intermittent assert failure issue that is being tracked. Change-Id: I6a7fcbdcf1e5b09842e88535f8442d2e1230748c
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.

2013-09-11New mode_info_context storage -- undo revertScott LaVarnway

2013-09-06New mode_info_context storageScott LaVarnway
mode_info_context was stored as a grid of MODE_INFO structs. The grid now constists of a pointer to a MODE_INFO struct and a "in the image" flag. The MODE_INFO structs are now stored as a stream, eliminating unnecessary copies and is a little more cache friendly. For the test clips used, the decoder performance improved by ~4.3% (1080p) and ~9.7% (720p). Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p) and 5.9% (720p).
