how can I change the format** to 320x240, 160x120 or 80x60

for this project a minimum frame rate 16fps is probably required…

if I change format by deleting and typing, I get error message: 

frame height is 240 but image height is 480.

How do I change the Image height?

regards

Jonathan

**640x480 wxcam wfm Arch on Raspberry Pi the frame rate is low  ~1-2fps
