Video stream signal switch - old video at bottom of new

[clsnordic]

Hello,

I am using a Raspberry PI 3 Model B with raspbian stretch (last update)

I am using the IVport-v2 dual module to switch between two raspberry pi cameras (Pi camera 2.1), and streaming this data over network to a receiver. The issue I’m having is that when I use the ivport_test_A.py (Which switches the status of GPIO pin 7,11 and 12) script to switch cameras, camera 2 gets a bar at the bottom with the picture from camera 1 (See attached files).

Camera 1 GPIO settings are:
Code: Select all

GPIO.output(7,True)
GPIO.output(11,False)
GPIO.output(12,True)
Camera 2 GPIO settings are:
Code: Select all

GPIO.output(7,False)
GPIO.output(11,True)
GPIO.output(12,False)

The first file I have the stream from camera 1 showing, and when I switch live to camera 2, part of the camera 1 stream is at the bottom. If I switch back to camera 1 again, the stream acts normally.

I use raspivid for the video (the bar shows in the preview window as well as the stream)

Is there something i’ve forgotten to solder/connect, or is this intended behaviour? Has anyone experienced this?

Best regards,
Christoffer
