Re: Streaming 2 cameras at home & with FMS

That feature of logging has not been implemented. The signal strength and bandwidth were hoped to be calculated by the radio itself and logged over time, but that was actually with a different radio solution, and it is not being used.

The easiest may be to use the Windows Task manager. Open the Networking tab and in View, add the Bytes per Interval column. There may be a better display elsewhere, but that seems to work pretty well.

Re: Streaming 2 cameras at home & with FMS

Here's a screensteps on measuring bandwidth:
http://wpilib.screenstepslive.com/s/...andwidth-usage

Be aware that image compression can easily cause a video stream to jump from 5Mbs to over 7 Mbps on the real playing field.
We always target keeping our combined robot bandwidth under 2Mbs to start with. It can always be increased later after seeing how it behaves on the actual playing field.

The success of image compression in keeping your bandwidth low is very dependent on the complexity of the image.
Images collected at home, pit or practice field can be quite different from the diamond plate, A/V lit, robot cluttered images you'll encounter on the playing field.
