GPU Offloading & Usage

Hi All,

I have some basic doubts (which may sound silly), please clarify: 

how we can say that, when we run sample applications (lets say multi_transcoding_drm), is running on/offloaded to GPU? I could see the following log messages while running the sample application:

Pipeline surfaces number: 14
MFX HARDWARE Session 16 API ver 1.16 parameters:  -->Is this telling that it is offloaded to GPU?
Input  video: AVC 
Output video: MPG2

I'm using Intel-NUC-Kit-NUC5i7RYH. Is there any special hardware chip which is doing video transcoding thing in this kit? 

Is there any CLI tool for calculating the GPU usage (something like top in linux)?

Hi There,

You are using Linux, right ?

For Linux, if you install MSS , you can find metrics_monitor under  /opt/intel/mediasdk/tools/, you can refer to metricsmon-man.pdf in doc folder.

 

Thank,

Zachary
