Cast not work or work slowly

[marcinzel]

Hi, I have problem with run cast from phone to MMM-ScreenCast. My board is RPI4. Other modules work ok. I run npm in debug mode and paste below log. Please help me repair issue.

@marcinzel this is an odd one. do you have any more info or any more logs? Can you try and run it like:

display=:0 npm start >> log.log

can you also provide me with info on the OS you using on your RPI?

Good Afternoon Kevin. I have just enterer into the RaspberryPi world and chose your module as my first to install. I have a new install on a Pi 4b 4gb (rev C03112), Raspbian GNU/Linux 11 (bullseye) My MagicMirror2 install only has the default modules installed, which are all working fine. I have installed MMM-Screencast with no problem, and have added the configuration.

When I try to cast Youtube from my iPhone XS Max or iPad Pro, I can see the pi (MirrorCast) but they do not connect. On the iOS devices the cast icon just flashes, but never connects. I have read every post I could find on this issue, but have not been able to resolve the problem.

I configured MMM-Screencast is it's default position, and have ensured there are no other modules conflicting with this position.
I have attached my install log and the log from the procedure you listed above

Personally, I've found this to be a performance limitation of the Raspberry Pi's, I was trying to use this with MagicMirror2 and a Raspberry Pi 3B and the performance was shocking, switched this out for an old 2011 MacMini and it works wonders now.
