Performance Metrics

Analyze Test Configuration:

libgav1 2019-10-05

Video Input: Summer Nature 4K

OpenBenchmarking.org metrics for this test profile configuration based on 375 public results since 5 October 2019 with the latest data as of 28 April 2021.

Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. It is important to keep in mind particularly in the Linux/open-source space there can be vastly different OS configurations, with this overview intended to offer just general guidance as to the performance expectations.
