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 conneted to Full HD screen.
CPU usage referes to the process under test as reported by top application.
Use case #1[edit | edit source]
- Description: playing H264 RAW video 1920x1080@25fps
- CPU usage: 30%
