Issue with usb_cam: select timeout yuyv usb_cam package

Hello, so my issue has to do with the yuyv pixel format in the usb_cam package. My launch file and everything works well with mjpeg and I can't understand why. I have installed and reinstalled OpenCV twice now (I'm running Ubuntu 14.04.4), from compiling the source code AND from script(repositories) and two different versions. Whenever I launch my launch file (with yuyv pixel format), the image halts, gets chopped up like [this](http://imgur.com/IxgEauI) and I get: [ERROR]: select timeout And then the process dies. I've also installed the perception ROS package for image processing. Here is my launch file Is this some sort of problem with the buffer size since the resolution is too high? Maybe the framerate is too high? I've changed both to half and saw no results so I don't think that's it. I've been looking around but most people seem to have issues with select timeout all around, not just on one pixel format. Thank you
