Kvazaar

This is a test of Kvazaar as a CPU-based H.265/HEVC video encoder written in the C programming language and optimized in Assembly. Kvazaar is the winner of the 2016 ACM Open-Source Software Competition and developed at the Ultra Video Group, Tampere University, Finland.

To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark kvazaar.

Performance Metrics

Analyze Test Configuration:

Kvazaar 2.2

Video Input: Bosphorus 4K - Video Preset: Medium

OpenBenchmarking.org metrics for this test profile configuration based on 1,048 public results since 4 January 2023 with the latest data as of 23 March 2024.

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.
