===Three cameras === | |||
Using the following pipelines we can test the performance of the Jetson TX2 when doing dual capture: | |||
==== Nvcamerasrc ==== | |||
<pre style="background:#d6e4f1"> | |||
gst-launch-1.0 nvcamerasrc sensor-id=0 fpsRange="30 30" ! 'video/x-raw(memory:NVMM), width=(int)3840, height=(int)2160, format=(string)I420, \ | |||
framerate=(fraction)30/1' ! fakesink nvcamerasrc sensor-id=1 fpsRange="30 30" ! 'video/x-raw(memory:NVMM), width=(int)3840, height=(int)2160, \ | |||
format=(string)I420, framerate=(fraction)30/1' ! fakesink nvcamerasrc sensor-id=2 fpsRange="30 30" ! 'video/x-raw(memory:NVMM), width=(int)3840, \ | |||
height=(int)2160, format=(string)I420, framerate=(fraction)30/1' ! fakesink | |||
</pre> | |||
We noticed that using three cameras with the max resolution '''3840x2160''', the cpu load consumption measured with tegrastats doesn't change considerably, and it remains almost the same: | |||
