Hello,

We have Leopardboard 365 ver 1.4

I installed the SDK under https://www.ridgerun.com/developer/wiki/index.php/DM365_Leopard_SDK_2011Q2_Getting_Started_Guide

To earn the video out, seized http://designsomething.org/leopardboard/f/33/t/409.aspx

Use a command to output the test video on TV

gst-launch -v videotestsrc ! dmaiperf print-arm-load=true ! 'video/x-raw-yuv,width=640,height=480, framerate=30/1' ! TIDmaiVideoSink videoStd=D1_NTSC videoOutput=composite accelFrameCopy=FALSE sync=false

receive fps: 10; CPU: 100.

In the derivation of the test video (encoded h264) team via Ethernet

What causes high CPU utilization and reduce fps?
