[Elphel-support] Stream stopping after setting decimation

[Oleg]

Hi,

1. Do you see the image degradation and image dimensions changes in the web
interface after the parameters are applied? Do images keep refreshing there
(or check mjpeg stream)?
Also, check http://192.168.0.9:2323/meta - refresh the page a few times and
check if the frame counters are updating?

2. In your log I see fps was 2.5.
Was autoexposure running?

Best regards,
