I am using a logitech c525 and the usb_cam ros package. I am using [this](http://sauravag.com/2015/03/how-to-tracking-aruco-marker-using-a-usb-webcam-and-ro/)(step#8 in this link) to get a stream of the usb_cam.
The frame rate is supposed to run at 30 hz but it barely ever gets to that rate. It says it is changing to 8hz but its not even 8hz([link_to_screenshot](https://drive.google.com/open?id=1_dlw27crz-9EPTxrEK389DASsiP049j9))(attached below as pic1) and sometimes it just says timeout and the process dies([link to screenshot](https://drive.google.com/open?id=1GumWmnZVpAopVgewAPUIgv68i8oA0ix5))(attached below as pic2).
Anyone know how to solve this issue?
