@cmille34 Hey, thanks for your answer. I appreciate that. My NVR only provides still JPEGs or RTSP for pictures. If I use JPEGs I have to reload them in a 200ms interval to achieve acceptable motion.

At this point, I have tried the following:

1. uses MMM-iFrame

• do the reload via embedded HTML meta-tag
• strong flickers (approx. half of the time blank)
• works, but not visually accaptable
• does not scale due to the flickering

2. use MMM-iFrame

• do the reload via embedded Java-Script function
• almost no flicker, almost fluid motion
• works for 30-60 minutes, then the module stops
• does not scale since it stops earlier with more modules

3. use oxmplayer as an overlay

• needs '–avdict rtsp_transport:tcp ’ switches to work without banding
• rtsp with 640x360 works with 30fps
• tested to concurrent streams

I am happy with the omxplayer solution even though it is not integrated in the MagicMirror. But for the user it looks integrated and it delivery a very good video quality.

@iwaldrum your project looks great! It is almost the module configuration I am also aiming for. Could you share how you integrated the surveillance cameras (iframe code)? I have trouble integrating mine. They offer rtsp and also jpegs that you can pull via http request. Which seems to be very similar to your setup. I would be interested in how you used the iframes to do it. Did you simply put the token-url in the iFrame-Module? How did you handle the refresh? Maybe you could share some code.
Thanks very much
Wolf
