Help with Axis Cameras

[EmileH]

The USB cameras are a bit finicky, if your team uses the SmartDashboard (Java/C++) to view robot data and such, you will need to add a patched camera widget to the dashboard in order to view the camera feed if you are using the Simple Vision example code. The problem with using the stock camera viewer and the Simple Vision code is that the CameraServer (used in Simple Vision) does not send the mJPEG data with Huffman tables and causes an error on the Driver Station, preventing you from seeing your video feed. One way to solve this would be to use the Intermediate Vision example class, however it takes a lot of the RoboRIO CPU to decode and then re-encode the video for viewing on the dashboard, but adds the Huffman tables in the process. If you want to save your RoboRIO some CPU load, and insert the Huffman tables in on the DS computer, use this camera widget.
So you can use the USB camera with the Simple Vision example class (which uses the WPILib CameraServer) and view the image on the DS with the patched widget.
