Screen Capture Device not detected

[ashaychangwani]

I am using the latest version of Hyperion.

• I confirm that this is an issue rather than a question.

Bug report

Hyperion shows no device found even when screen grab is enabled and LEDs are reacting to the screen being shared

Steps to reproduce

Start hyperiond server
connect to it from MacOS client using the https port
click the screen grab button
start sharing screen

What is expected?

The device sharing the screen should be detected. I should be able to modify the settings for it.

What is actually happening?

The device is not detected and I can't find any way to change the settings for it.

It is perfectly fine, that Hyperion shows you that there is no capture device. This happens, if Hyperion identifies, that none of the provided screen grabbers will work with the current system.
All other ways of feeding images, e.g. USB Grabber,‘ Flat-ProtoBuffer, Effects will still work.

Background: On rpi4 and newer OS the display driver was changed. Hyperion currently has no support for the new driver.
Nevertheless, you can activate the legacy driver to have screen grabbing running. See here #954 (comment)

Alternatively, you or anybody else is welcome to provide a new screengrabber for this configuration via a PR.
