2016-02-16vp10,encoder: relocate setjmpJames Zern
move to encoder_encode() as vp10_get_compressed_data() allocates data and would require some modification to make its error return meaningful. Change-Id: Ia5267c35d16ccd42b6da6d2136402b13e28f9159

2016-02-08Explicitly set tx_type for sub8x8 blocksDebargha Mukherjee
Fixes an issue where the tx_type was not set correctly for sub8x8 inter and intra blocks. In the current syntax, for sub8x8 blocks, there is still a single tx_type that is transmitted. Ideally, this should be searched for the best rd performance, albeit at the expense of encode speed. For now, we just set it to DCT_DCT. Previously it was left incorrectly as what was used for the previous non sub8x8 block. derflr: BDRATE -0.277% Change-Id: If76ba903bfbfd4d374cf1ac7d1daee50e92f0edd

the lookahead buffer allocation is deferred to receipt of the first frame to allow profile changes. if the encoder was flushed before supplying any frames the encoder would crash trying to dereference the NULL buffer. vp8 is unaffected. fixes mozilla bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1237848 Change-Id: Icee4b64de760476eee0d33b568f0a1010335ff13

2016-01-04vp10: only assume ONLY_4X4 if segmentation is disabled.Ronald S. Bultje
Otherwise, per-segment lossless might mean that some segments are not lossless and they could still want to use another mode. The per-block tx points remain uncoded on blocks where (per the segment id) the Q value implies lossless. Change-Id: If210206ab1fe3dd11976797370c77f961f13dfa0

2015-12-151 pass VBR mode bug fix.paulwilkins
(copied from VP9) The one pass VBR mode selects a Q range based on a moving average of recent Q values. This calculation should have been excluding arf overlay frames as these are usually coded at the highest allowed value. Their inclusion skews the average and can cause it to drift upwards even when the clip as a whole is undershooting. As such it can undermine correct adaptation of the allowed Q range especially for easy content. Change-Id: I9e12da84e12917e836b6e53ca4dfe4f150b9efb1
2015-12-14Fix a enc/dec mismatch under CONFIG_MISC_FIXESYaowu Xu
The culprit is on the decode side xd->lossless[i] setup was in wrong location where segment features are not yet decoded. Also on the encoder side, transform mode was not set consistently between when tx_mode is selected and how tx_mode is enforced in tx size selection.

2015-12-08Changes to exhaustive motion search.paulwilkins
This change has been imported from VP9 and alters the nature and use of exhaustive motion search. Firstly any exhaustive search is preceded by a normal step search. The exhaustive search is only carried out if the distortion resulting from the step search is above a threshold value. Secondly the simple +/- 64 exhaustive search is replaced by a multi stage mesh based search where each stage has a range and step/interval size. Subsequent stages use the best position from the previous stage as the center of the search but use a reduced range and interval size. For example: stage 1: Range +/- 64 interval 4 stage 2: Range +/- 32 interval 2 stage 3: Range +/- 15 interval 1 This process, especially when it follows on from a normal step search, has shown itself to be almost as effective as a full range exhaustive search with step 1 but greatly lowers the computational complexity such that it can be used in some cases for speeds 0-2. This patch also removes a double exhaustive search for sub 8x8 blocks which also contained a bug (the two searches used different distortion metrics). For best quality in my test animation sequence this patch has almost no impact on quality but improves encode speed by more than 5X. Restricted use in good quality speeds 0-2 yields significant quality gains on the animation test of 0.2 - 0.5 db with only a small impact on encode speed. On most natural video clips, however, where the step search is performing well, the quality gain and speed impact are small. Change-Id: Iac24152ae239f42a246f39ee5f00fe62d193cb98

The custom LCG is based on the POSIX recommend constants for a 16-bit rand(). This implementation uses less computation than typical standard library procedures which have been extended for 32-bit support, is guaranteed to be reentrant, and identical everywhere.
