[canis-ferrin]

Regarless what I am doing, following the instruction, I get a gray website wit a text in the upper left corner: mse:streans: exec: exit status 1 and a spiiner in the center of the page.
What' wrong?
config.yaml:

streams:
  Kamera127:
  - rtsp://admin:xxx@192.168.211.127:554/mpeg4cif
  - ffmpeg:Kamera127#video=mjpeg

I have to reduce bandwidth, Fully is not playing the video stream, Firefox does.
How can I redude bandwidth and resolution?

You can increase log level

The debug level log shows frequenty "[streams] can't stop none producer"
what does it mean?

I defined an old Linksys WVC54GC mjpeg- webcanm as:

Kamera111:  "ffmpeg:http://admin:xanthippe@192.168.211.111/img/video.mjpeg#width200"

The stream is working, but width is still 640

"can't stop none producer" means that the source failed to start by the time it needed to be stopped.
It could be due to incorrect config or camera issues.
For example, your config above is wrong
