Mmm, getting vorbis, opus or m4a to stream is going to be hard withour ffmpeg...

[matjaz]

Homey supports following codecs: mp3, ogg, flac. https://apps.developer.athom.com/tutorial-Media-Codecs.html There is no option to use ffmpeg on Homey, so transcoding should be done on some other device or in pure JS, which Homey is resource limited. So IMO no easy option.

[bvdbos]

transcoding in pure js, didn't know that was possible 👍 https://github.com/sopel39/audioconverter.js from: http://karolsobczak.com/?p=133 worth some testing....

Currently I'm in a process of rewriting app using Homey SDK 2 and oAuth. Please feel free to make standalone POC of Homey audio conversion app. (from youtube to playback directly on Homey).

[bvdbos]

Don't feel like I'm rushing you ;-) Using this bug to gather research for better youtube-audio support in Homey...

[matjaz]

I don't see a format which is directly supported in Homey. Vorbis is in webm container. I've managed to download youtube video using ytdl-core, convert it using audioconverter.js and play it in media manager using local streaming server. But in order to do that I needed to tweak pure js ffmpeg and create local streaming server. So technically it's possible, but practically it's not for realtime "search youtube and play" use case, because Homey is just to slow. It took me around 5 mins, to convert 3:26 video, while I received many cpuwarns. So maybe to create a pre defined list from YouTube and convert videos to mp3 and later play, it would be possible (but limited to disk space). Another option is to move transcoding to more powerful machine (server, nas, raspberry)
