Note: Encode time of a raw audio block parameter was only measured for AAC audio encode multimedia task. Video capture latency parameter was only measured for video capture multimedia task. This was the unique parameter measured for this task. | Note: Encode time of a raw audio block parameter was only measured for AAC audio encode multimedia task.

Different tools were used to measure the parameters specified in this test-bench. GstShark was the principal tool used to measure CPU load per core, frame rate and buffer processing time. GstShark is a benchmarking and profiling tool for Gstreamer pipelines developed by RidgeRun (If you want more information of this tool, please follow this link [https://developer.ridgerun.com/wiki/index.php?title=GstShark GstShark]) | Different tools were used to measure the parameters specified in this test-bench.
