2016-07-12 00:31:00 -0500	asked a question	No camera image in RVIZ? I am using ROS Indigo on Ubuntu 14.04LTS. Previously I am using my camera with RVIZ with no problem but today when I try to run my system as usual, the camera panel of RVIZ does not display my image from camera. I am sure that the camera is functioning well because there is no problem with image view, as shown in the screen shoot. https://drive.google.com/open?id=0ByE... The topic is selected correctly because there is no any error in status of RVIZ camera. Is this related to update of ROS or RVIZ? Any method to solve or investigate the problem?

2014-06-05 21:47:45 -0500	asked a question	Which camera driver can used to change setting of USB camera I am working on some simple image processing programming in ROS with USB webcam. I did tried on some camera driver such as gscam and uvc_cam, but every time after restart the PC and open my program, the camera image setting is back to default again although i already set it with guvcview. So I want to access the camera setting through camera driver. Please recommend a ROS usb camera driver that can let me -> disable the auto white balance and brightness -> set the white balance temperature and exposure level Thank you.
