Using the field trial WebRTC-VP9-PerformanceFlags, this CL allows you to configure the libvpx VP9 encoder with a list of flags to affect the quality vs speed tradeoff. This CL adds support for: * Speed (effort), for the temporal base layer frames * Speed for higher (non-base) layer frames * De-blocking (as part of the loopfilter) enabled for: 0 = all frames 1 = all but frames from the highest temporal layer 2 = no frames Each entry in the list has a threshold in min number of pixels needed for settings in the entry to apply. Example: Two spatial layers (180p, 360p) with three temporal layers are configured. Field trial "WebRTC-VP9-PerformanceFlags" set to: "min_pixel_count:0|129600,base_layer_speed:5|8,high_layer_speed:7|8,deblock_mode:1|2" This translates to: S0: - TL0: Speed 5, deblocked - TL1: Speed 8, deblocked - TL2: Speed 8, not deblocked S1: - TL0: Speed 7, not deblocked - TL1: Speed 8, not deblocked - TL2: Speed 8, not deblocked Bug: webrtc:11551 Change-Id: Ieef6816d3e0831ff53348ecc4a90260e2ef10422 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/188461 Reviewed-by: Michael Horowitz <mhoro@webrtc.org> Reviewed-by: Sergey Silkin <ssilkin@webrtc.org> Commit-Queue: Erik Språng <sprang@webrtc.org> Cr-Commit-Position: refs/heads/master@{#32749}
WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
Development
