Examples
--------
Capture from a CoaXPress camera via a Kaya Komodo frame grabber, apply AGC to convert it to 8-bit monochrome, then output the video via A&B Software GigESim which generates GigE Vision video:
> `gst-launch-1.0 kayasrc ! videolevels auto=continuous ! gigesimsink`
Then in another command capture the GigE Vision video via Pleora eBUS and display the video to the screen:
> `gst-launch-1.0 pleorasrc ! autovideoconvert ! autovideosink`
