[Elphel-support] Stream stopping after setting decimation

[Daniele Forsi]

Hi,

> 1. Do you see the image degradation and image dimensions changes in the web interface after the parameters are applied?

wtih DCM_HOR and DCM_VERT both at 2 the dimensions changed from 2592x1936 to 1293x960

> Do images keep refreshing there (or check mjpeg stream)? 

only one static image is received with the new size at http://192.168.0.9:2323/bimg but the stream at http://192.168.0.9:2323/mimg is showing a black page

> Also, check http://192.168.0.9:2323/meta - refresh the page a few times and check if the frame counters are updating?

currentSensorFrame and currentSensorFrameHex are updating but all other parameters aren't updating
