Re: [NE FIRST] Match Video Mega Thread
As Nathan from Mechanical Mayhem so kindly pointed out, the Ligerbots have a lot of video on our channel: https://www.youtube.com/channel/UCgNgdmtDs7d58dVR-80DCGA. Most of this is, of course, devoted...

Re: mjpg-streamer running on roboRIO
I believe I tried a few -q choices, but it was a while ago now.
I measured the bandwidth using the Windows task manager. Since there was nothing else on the WiFi between the laptop and the robot...

Re: mjpg-streamer running on roboRIO
It's worse than I thought. My earlier comparison was with the MJPG streamer at 10 fsp and my robot program at 24fps. The MJPG streamer uses about 3 times the bandwidth as the WPILib streamer running...

Re: mjpg-streamer running on roboRIO
Actually, it turns out the default shell script was working for me. I had forgotten to shut down FRCProgram, which also opened the camera!
But your scripts for starting, etc. will be helpful if we...

Re: mjpg-streamer running on roboRIO

Easiest thing that I can see is just to put everything under /var/local/natinst/www, since that would avoid...

We use the Talon in a similar manner to control our up/down elevator. By default, it's set to hold the elevator in place. But we also have manual joystick control (actually the triggers on an Xbox...

Well here's a new data point:
All of our Autonomous Command classes had a #include "../robot.h" in them (the students can be pretty sloppy about these things). I had meant to clean this up, but you...

Don't think so. None of the commands in our command groups seem to get run at all. Look at https://github.com/ligerbots/RecycleRush2015Robot/blob/dartFriday/src/Commands/Delay.cpp -- a command that...

Re: C++ USB Camera Errors
It's just flakey. Many of the underlying classes don't return errors (mostly declared void). If anything goes wrong, it just keeps spewing errors to the message window on the dashboard.

Video mode[95] is 320 x 240 JPEG 15.00 fps = 95
