quiets an integer sanitizer warning: vpx/src/vpx_image.c:101:25: runtime error: implicit conversion from type 'int' of value -2 (32-bit, signed) to type 'unsigned int' changed the value to 4294967294 (32-bit, unsigned) Change-Id: Ifeac31cc80811081c1ba10aadaa94dc36cd46efa
2021-04-28Bump ABI versionCheng Chen
Due to recent changes to command line options for rate control parameters. Change-Id: I1de7cb4ff2850a3ed19ec216dd9d07f64a118e92
2021-04-28Merge "vp8: enc: Fix valid range for under/over_shoot pct"James Zern
2021-04-21vp8: enc: Fix valid range for under/over_shoot pctSreerenj Balachandran
The overshoot_pct & undershoot_pct attributes for rate control are expressed as a percentage of the target bitrate, so the range should be 0-100. Change-Id: I67af3c8be7ab814c711c2eaf30786f1e2fa4f5a3
2021-04-20Further normalization of Vizier parameters.Paul Wilkins
Further changes to normalize the Vizier command line parameters. The intent is that the default behavior for any given parameter is signaled by the value 1.0 (expressed on the command line as a rational). The final values used in the two pass code are obtained by multiplying the passed in factors by a default values if use_vizier_rc_params is 1. Where use_vizier_rc_params is 0 the values are explicitly set to the defaults. This patch also changes the default value of each parameter to 1.0 even if not set explicitly. This should ensure safe /default behavior if the user sets use_vizier_rc_params to 1 but does not set all the the individual parameters. Change-Id: Ied08b3c22df18f42f446a4cc9363473cad097f69
2021-04-14Pass vizier rd parameter valuesCheng Chen
Add command line options for three rd parameters. They are controlled by --use_vizier_rc_params, together with other rc parameters. If not set from command line, current default values will be used. Change-Id: Ie1b9a98a50326551cc1d5940c4b637cb01a61aa0
2021-04-13Set vizier rc parametersCheng Chen
If pass --use-vizier-rc-params=1, the rc parameters are overwittern by pass in values. It --use-vizier-rc-params=0, the rc parameters remain the default values. Change-Id: I7a3e806e0918f49e8970997379a6e99af6bb7cac
2021-04-08vpx_image: clear user provided vpx_image_t earlyJames Zern

2021-04-06Change zm_factor for Vizier.Paul Wilkins
Changes the exposed zm_factor parameter. This patch alters the meaning of the zm_factor parameter that will be exposed for the Vizier project. The previous power factor was hard to interpret in terms of its meaning and effect and has been replaced by a linear factor. Given that the initial Vizier results suggested a lower zero motion effect for all formats, the default impact has been reduced. The patch as it stands gives a modest improvement for PSNR but is slightly down on some sets for SSIM (overall psnr, ssim % bdrate change: -ve is better) lowres -0.111, 0.001 ugc360p -0.282, -0.068 midres2 -0.183, 0.059 hdres2 -0.042, 0.172 Change-Id: Id6566433ceed8470d5fad1f30282daed56de385d
2021-03-29Add command line options for a few rc parametersCheng Chen
These rate control parameters are for the Vizier experiment. They are defined as rational numbers. Change-Id: I23f382dd49158db463b75b5ad8a82d8e0d536308
2021-02-03L2E: let external rate control pass in a max frame sizeCheng Chen
And allow the frame to recode when the frame size is larger than the input max frame size. If the max frame size is not specified, let vp9 decide whether to recode. The recode follows the vp9's current recoding mechanism. The rate control api will return the new qindex back to the external model. Change-Id: I796fbf713ad50a5b413b0e2501583b565ed2343f

2020-11-12vp9: Allow for disabling loopfilter per spatial layerMarco Paniconi
For SVC: add parameter to the control SET_SVC_PARAMS to allow for disabling the loopfilter per spatial layer. Note this svc setting will override the setting via VP9E_SET_DISABLE_LOOPFILTER (which should only be used for non-SVC). Add unittest to handle both SVC (spatial or temporal layers) and non-SVC (single layer) case. Change-Id: I4092f01668bae42aac724a6df5b6f6a604337448

2020-08-25vp9-rtc: Add control to disable maxq on overshootMarco Paniconi
Add encoder control to disable feature to increase Q on overshoot detection, for CBR. Default (no usage of the control) means the feature is internally enabled. Add the control to the sample encoders, but keep it disabled as default (set to 0, so feature is on). Change-Id: Ia2237bc4aaea9770e5080dab20bfff9e3fd09199

2020-05-04Remove unneeded null check for entry in for loopWan-Teh Chang
In vpx_codec_control_(), before we enter the for loop, we have already checked if ctx->iface->ctrl_maps is null and handle that as an error. So the for loop can assume ctx->iface->ctrl_maps is not null, which implies 'entry' is not null (both initially and after entry++). Change-Id: Ieafe464d4111fdb77f0586ecfa1835d1cfd44d94

2020-04-02Return VPX_CODEC_INCAPABLE on capability failureWan-Teh Chang
All decoder functions should return the VPX_CODEC_INCAPABLE error code if the algorithm does not have the requested capability. Move the definitions of VPX_CODEC_CAP_FRAME_THREADING and VPX_CODEC_CAP_EXTERNAL_FRAME_BUFFER to the VPX_CODEC_CAP_* section. Change "PUT_SLICE and PUT_FRAME events are posted" to "put_slice and put_frame callbacks are invoked". Also fix some other minor comment errors. This carries back to libvpx the following libaom CL: https://aomedia-review.googlesource.com/c/aom/+/108405 Change-Id: If67a271c9abbb3eebc2359719cc7d9f235b690d2
