Camera Lag
I'm having a hard time reducing the amount of lag i get from live camera feed. I have tried messing with compression and resolution but i still have like a 5 secound lag.
The following code, writen in Java, is the example dashboard code with camera feed added, i put my additions, camera feed code, in blue.

public class DashBoardExample extends IterativeRobot {
/**

public void robotInit() {
AxisCamera.getInstance().writeResolution(AxisCamer a.ResolutionT.k160x120);
AxisCamera.getInstance().writeBrightness(0);
Watchdog.getInstance().setEnabled(false); }
/**

public void autonomousPeriodic() {
//Update Camera Feed
DriverStationLCD.getInstance().updateLCD();
}
/**

public void teleopPeriodic() {
//Update Camera Feed
DriverStationLCD.getInstance().updateLCD();
updateDashboard();
}

Theres a little bit more code but the rest of it is not related to the camera.
Is there anyway to reduce the lag. |
