The video encoders on the Portsdown transmitter need specific configuiration for each video device. Information about some of these devices has been collated on this page. The exact model of device can be found by using the Linux command lsusb and checking the manufacturer and device IDs - each are 4-digit hex numbers.
The information needed to configure the cameras for the Portsdown can be gleaned from the following commands:
v4l2-ctl --list-devices v4l2-ctl -d /dev/video1 --list-formats-ext arecord -l arecord -f S16_LE -c 2 -r 60000 -D hw:1,0 -d 5 testS16_LE.wav
Then trial and error is required to fine-tune the response.
