Introduction[edit | edit source]
This page lists some statistics and information about real use cases based on Naon Embedded Linux Kit (NELK).
Gstreamer-based applications[edit | edit source]
For the sake of completeness, for each use case the full command line used to run the test applicaiton is provided.
Video decoding and playing[edit | edit source]
Output is HDMI port connected to Full HD 46" TV screen.
CPU usage refers to the process under test as reported by top application.
Use case #1[edit | edit source]
