uvc_camera mjpeg support

Hello, I just got an ELP-USBFHD01M-L21 UVC webcam I want to use with ROS. It supports 120 FPS with 640x480 resolution via mjpeg encoding, which I have confirmed with guvcview. However, I cannot get either libuvc_camera or uvc_camera to support this encoding, and I'm forced to use the 30 fps supported by yuyv encoding.

Is there a webcam driver for ROS that supports mjpeg, or any way I can modify libuvc_camera to recognize this encoding? It seems that mjpeg is not recognized, and defaults to yuyv.

I'm using ROS indigo on 14.04 ubuntu.
