  • As a music lover, I want to be able to go to sleep using my Chromecast Audio by playing music for a length of time, and then that music fades out, so I get a good night’s sleep.

#2

Should the other Chromecast Skill be merged into this one?


#3

Good question, I don’t know ^^.


#4

I will see which one gets the most response, and then merge the one with the least responses.


#5

where does it get music, I’m assuming just google play?


#6

No, here is a list of platform where you can get the music from : https://store.google.com/us/product/chromecast_audio_apps?hl=en-US

And it’s huge ! (The list of course… :grin:)


#7

Uhm, but this is a (huge) list of apps that use chromecast as an audio output… which is exactly what it is. The interface you are talking about would be with one of these apps, like spotify (which has a skill), then output spotify to chromecast. Searching would mean, searching IN spotify, then outputting to chromecast, sonos or whatever.

I asked myself the exact same question as @12buntu, and thought you were talking about a local usb disk , or online platform. Not using one of the other apps. Spotify has default chromecast output in it for instance


#8

It seems like this should be an option for audio output from Mycroft itself, not necessarily any of the supported apps in the list. Mycroft support for the individual apps would be handled as skills for those apps. That way the support for ChromeCast Audio would be in place, and any additional skills that come along with an audio component (NPR, Spotify, Google Music, whatever) would already have the ChromeCast Audio support without any additional complications.


#9

You are right ! And it can be the same for all 3rd party devices like Sonos :slightly_smiling_face:


#10

The audio system has a basic proof of concept for chromcast, but we sort of need to redo parts of it to make it more dynamic (and it would be good to find a better chromecast media play than the default one)

Currently it only scans for chromecasts at startup and makes the ones it finds available as targets for audio playback play news on <Chromecast name>


#11

I’d really like to see this on an open source based platform so no need for spys like google or spotify.
