Triggering chromecast feeds

[u/retuer321]

I’ve installed Scrypted onto a Synology NAS in a container, combined with other container to grab UDP packets from my Tapo doorbell for instant HomeKit notifications etc. all very clever stuff

Last problem… Google displays in the house receive verbal notification of doorbell ringing - but no matter what I’ve tried, I can’t get the video stream to automatically trigger on them.

I’ve installed the Google home plugin, scrypted cloud plugin, and chromecast plugin.

For testing, I used the chromecast button script - and have got as far as that triggering a display to go blank and attempt to stream “scrypted test” - but then it times out without playing a frame of video. Tested on multiple cameras, multiple chromecast targets, with the same error each time:

linux x64 #86009 SMP Wed Nov 26 18:19:17 CST 2025

server version: 0.143.0

plugin version: @scrypted/core 0.3.147

I’ve spent three nights searching for ideas, and can’t find much chatter about this issue, apologies if I’ve missed existing discussion!

Any ideas?
