2014-04-01Remove the q division by 3 for first frame.Marco Paniconi
This code/setting was actually not used (since speed features were not set on first frame, until a recent change) and should be removed. In CBR mode, the q value for the first frame can be controlled by setting the target size via the parameters rc_buf_initial_sz (and max_intra_size_pct).

2014-04-01Speed setting correction to max q estimate.Paul Wilkins
Use a crude correction factor to correct for lower compression efficiency at higher encode speeds when estimating the max Q for the clip. Change-Id: I5ae377647f4adf5e91d700a8791fb3b8f70efc73
2014-03-31Apply finer quantizer to partition search frames in non-RD flowJingning Han
This commit optimizes the bit allocation for the non-RD coding flow. It applies slightly better quantizer to the frames, where all blocks run a non-RD partition search. Such frames typically have better rate-distortion trade off, thus improving the reconstruction quality for next few frames reference at reasonably low increment in rate cost. The coding performance for rtc set at speed -5 with error-resilient tuned on and rate control set as cbr is improved by 19.58%. It improved the coding speed by about 10% for a portion of local test clips. Change-Id: I9d56696cd4359dc8136ca10aff10fff05aaa2686

2014-02-25Adds variance based fixed size partitioningDeb Mukherjee
Adds a method for determining a fixed size partition based on variance of a 64x64 SB. This method is added to rtc speed 6. Also fixes a bug in rtc_use_partition() and includes some refactoring related to partitioning search, and some cosmetics. Currently compared to speed 5, the coding efficiency of speed 6 is -19% and that of speed 7 is -55%, in cbr mode. Change-Id: I057e04125a8b765906bb7d4bf7a36d1e575de7c6

2014-02-11Removes active_worst_quality feedbackDeb Mukherjee
Removes certain cases of feedback of active_worst_quality, and removes it from the RATE_CONTROL structure. Now active worst quality is expected to be computed locally in the q picking function during the encode. Making temporal filter strength depend on avg_frame_qindex rather than on active_worst_quality actually improves performance esp. for yt. derf: +0.038% yt: +0.359% Change-Id: I1fe5a343034b55af9322289165321f00ac0827b1

2014-02-06Parameter fixes for one-pass non-cbr modeDeb Mukherjee
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
2014-02-06Layer based rate control for CBR mode.Marco Paniconi
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

2014-02-05One-pass rate control cleanups/fixes/refactoringDeb Mukherjee
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.

2014-02-04One-pass rate control fixes and cleanupsDeb Mukherjee
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%.

2014-01-29Enables alt-ref frames in one pass modeDeb Mukherjee
Includes a few fixes and clean-ups that adds the ability to use alt-ref frames in one-pass mode. Whether alt-refs are actually used or not is controlled by a macro USE_ALTREF_FOR_ONE_PASS in vp9_firstpass.c. This first cut seems to improve derf by 15+% in 1-pass mode. But further experiments with parameters are underway. Change-Id: I78254421435478003367c788c7930d2dc4ee2816

2014-01-14Add max burst bitrate control.Paul Wilkins
Applies an upper limit on burst bitrate for any frame. This is to insure that typical encodes for YT do not produce frames that are so large that they risk stalling HW implementations. Such frames could also cause playback problems in SW. For now the limit is set at 250 bits per MB for 1080P and larger (with the 1080P limit used for smaller frames). Setting maxQ, constant quality mode or targeting a very high bandwidth will have precedence over this limit. Change-Id: Ie6f776c38b06ac7cec043d034085f4b79ee46a38
