A bug was reported in Issue 702: "SIGILL (Illegal instruction) when
transcoding with vp9 - using FFmpeg". It was reproduced and fixed.
Change-Id: Ie32c149a89af02856084aeaf289e848a905c7700
Fixes some of the parameters for 1-pass non-cbr mode.
Also includes some cleanups, inlcuding refactoring of the
recode_loop options.
Results on derfraw300 improve by about 5-6%, so that the one-pass
mode is now 13% below the 2-pass mode in speed 0.
Change-Id: I844cc2638694c7574f3be00d41d60b23dc1016f0
This patch adds a buffer-based rate control for temporal layers,
under CBR mode.
Added vpx_temporal_scalable_patters.c encoder for testing temporal
layers, for both vp9 and vp8 (replaces the old vp8_scalable_patterns).
Updated datarate unittest with tests for temporal layer rate-targeting.
Change-Id: I8900a854288b9354d9c697cfeb0243a9fd6790b1
Inlcudes a number cleanups:
1. Moves the one-pass pre-encode parameter setting functions
to vp9_ratectrl.c
2. Deprecates per_frame_bandwidth in RATE_CONTROL structure
3. Removes target_bandwidth in cpi structure since it is not used.
4. Various renaming of functions
There is no bit-stream change in 2-pass, one-pass cbr and one-pass
vbr modes.

Fixes rate control partially in one-pass non-cbr case to achieve a
bitrate close to the one desired. Previous version was way off at
the high bitrate end.
Also includes several one-pass rate control cleanups and refactoring.
On derfraw300, one-pass encoding is now 19% off from two-pass speed
0 encoding, down from 35%.
Change-Id: I6f0dcdb7f8aa85a7e7cd3a3155d4f9d2a4d2f4f4
Moved a few features with low impact on compression form -5 to -4 and
increased adaptive_rd_thresh for -5.
Change-Id: Ib1b748168cc6ed7684ae4818499f3a536ae76253
This avoids calls to get_unsigned_bits() with constants and
replaces hard to trace loops with simpler structures.
