2018-10-03vp8: Increase rate threshold for overshoot-dropMarco Paniconi
Increase the rate threshold for the dropping when overshoot is detected during encoding. This helps to prevent some unneccessary drops for hard content. Change-Id: I258bf33883d46347efd44e1e192cb25c444d05fe

2017-08-02vp8: Drop due to overshoot for non-screen content.Marco
For 1 pass CBR mode: Apply the logic for dropping (and re-adjusting rate control) due to large overshoot to the case of non-screen content when drop_frames_allowed is enabled. For the non-screen content case: add additional condition that rate correction factor is close to minimum state, and flag to constrain the frequency of the dropping. Also handle the case of temporal layers and multi-res encoding. Add some flags/counters to the layer context for temporal layers. For multi-res: drop due to overshoot is checked on lowest stream, and if overshoot is detected we force drops on all upper streams for that frame. This feature is to avoid large frame sizes on big content changes following low content period. No change in behavior for screen_content_mode = 2. Change-Id: I797ab236cbbf3b15cad439e9a227fbebced632e6

2016-10-19vp8: Add control for gf boost for 1 pass cbr.Marco
Control already exists for vp9, adding it to vp8. Usage is only when error_resilient is off. Added a datarate unittest for non-zero boost. Change-Id: I4296055ebe2f4f048e8210f344531f6486ac9e35
2016-10-07vp8: Change default gf behavior for 1 pass cbr.Marco
In 1 pass CBR, with error_resilience off, allow for special logic to change the default gf behaviour. In this CL: boost is turned off and the gf period is set to a multiple of cyclic refresh period. Change only affect 1 pass CBR mode, i.e, when the flag gf_update_onepass_cbr is set. Including the previous change (3ec8e11: to allow cyclic refresh for error_resilience off), comparing metrics on RTC set for error_resilience off vs on: avgPSNR/SSIM up by ~6%.

2013-11-01Fixes to buffer update for temporal layers.Marco Paniconi
When a frame is dropped due to |buffer_level| < 0 for a given temporal layer, the buffer level for the upper temporal layers was not updated (in calc_pframe_target_size()). This change fixes that. Also, use the layer per-frame-bandwidth for updating the buffer level of the higher layers when a frame is dropped. Change-Id: I660c23f3229b47e9d124a950b480314b4307c5a8

2012-11-26Updates to qp-regulate and rate correction factor.Marco Paniconi
Don't use the switch to gf_rate_correction factor when temporal layers is used (i.e., cpi->oxcf.number_of_layers > 1). In temporal layers, we prefer to avoid this as any frame (e.g., base layer frame at anchor of pattern) may update both last and golden (and possibly alt-ref), and so we would get different rate correction factors within the same layer. This change will make sure one rate correction factor exists for each layer. Also, made some other code in qp-regulate that depends on alt/golden update specific to the 1 layer case.

2012-07-27Remove the resetting of qp params for temporal layers.Marco Paniconi
The ambient qp and active worse/best qp were reset for every frame when temporal layers is on. This change removes this reset. As this affects the target size for forced key frames (it will actually lower the size somewhat), we increased the inital boost factor to compensate.

Allows building the library with the gcc -pedantic option, for improved portabilty. In particular, this commit removes usage of C99/C++ style single-line comments and dynamic struct initializers. This is a continuation of the work done in commit 97b766a46, which removed most of these warnings for decode only builds. Change-Id: Id453d9c1d9f44cc0381b10c3869fabb0184d5966

2012-04-23Shares one set of RD costs tables between all encoding threadsAttila Nagy
RD costs were local to MACROBLOCK data and had to be copied all the time to each thread's MACROBLOCK data. Tables moved to a common place and only pointers are setup for each encoding thread. vp8_cost_tokens() generates 'int' costs so changed all types to be int (i.e. removed unsigned). NOTE: Could do some more cleaning in vp8cx_init_mbrthread_data(). Change-Id: Ifa4de4c6286dffaca7ed3082041fe5af1345ddc0
