Update 0.24: New Trait Camera Stream
Big thanks to @lpakula for contributing this.
The app now supports the Camera Stream trait. This trait will allow you to view the video feed from cameras on Chromecast and Nest devices. It also includes wrapper device drivers to expose the camera feed URLs to the app if your camera either doesn't have a Hubitat driver or its driver doesn't expose an attribute to get the URL to its video feed. Note that Google requires a pretty specific set of video and audio encodings and streaming protocols, so you may need to pass the feed through some other PC application to convert it if it doesn't produce a suitable stream natively (notably, RSTP streams are not supported).
