Performance Metrics

Analyze Test Configuration:

Mencoder 1.3.0

AVI To LAVC metrics for this test profile configuration based on 445 public results since 7 February 2018 with the latest data as of 12 June 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.
