Re: mjpg-streamer running on roboRIO
Actually, a simple web browser will do the display just fine. You can compile mjpg-streamer for vlc, udp, rtsp or one of several other options. However, we've just been using the output_http.so...

Re: mjpg-streamer running on roboRIO
Actually, you drop a Javascript page onto the ./www directory that has a button that allows you to switch between the streams. So, you're not getting both streams simultaneously unless you want...

Re: mjpg-streamer running on roboRIO
The Logitech C920 does hardware H.264 encoding. Mjpeg-streamer understands that and doesn't repeat the process. This significant;y lowers CPU utilization.

Here at the Orlando Regionals while waiting in the pits for our robot to start working, I ported mjpg-streamer to the roboRIO. It was pretty funky since the source doesn't lend itself to...

Re: USB Cameras
Greetings!
Here is code that runs dual USB cameras. It's in the form of a C++ Eclipse project. It should be extensible to multiple (more than 2) cameras. The process is a bit convoluted because...

Re: Multiple cameras on one Robot
We have multiple USB cameras working on the bot in C++. So far, we've only tested two cameras because that's what we need for our bot. But, it looks like it should be scalable to more cameras as...

Re: Dual Cameras?

Dual Cameras?
Hmm... OK, in looking through the WPILib sources (C++), it appears that the camera server is hard-coded to camera 0. Not only that, but the NI vision system remembers which cameras were enumerated...
