Support streaming local device, like microphone in / aux in? about go-cast HOT 6 CLOSED

Hey - you could potentially do this - you'd need a webserver serving up an audio stream of the data on an http url, and then you can start the cast playing from this by doing cast --name Chromecast media play http://streamurl/. It'd play wav, mp3, etc.

As to serving up a microphone as a stream - fmpeg/ffserver might be able to (not tested):

There are many ways to do this using a PC as an intermediary.

• https://github.com/acidhax/chromecast-audio-stream/
• https://www.addictivetips.com/windows-tips/how-to-stream-audio-from-your-pc-or-mac-to-chromecast/
• BubbleUPNP can create a DLNA endpoint on your PC (or Android) that can forward to the Chromecast Audio and you can use that to direct a microphone to your chromecast.
• On Linux there is a configuration for pulseaudio to do it as well, but I've not done it.
• As far as forwarding a recording from the line-in or mic input on your PC you should be able to do that once you get the PC's audio streaming to the the Chromecast. Then set the microphone/input properties to "listen" in control panel. On my Windows 10 it is Settings > Sound > Input > Device Properties > Listen > Check the "Listen to this device" button.

Interesting... I'm basically working with a line-in aux cable, and I currently have a couple different Raspberry Pi's (and a macbook if I need) to work with.

I'll look into hosting the ffmpeg server, otherwise it looks like maybe I could hook up to the input device in alsa?

Yeah, for RPi you can use http://mkchromecast.com/ and Alsa but you'll need a USB soundcard that has an input since the basic RPi hardware doesn't have audio-in. There are lots of options but nothing is a perfectly simple solution AFAIK.

Hm - I'm going to try to use https://fe-pi.com/products/fe-pi-audio-z-v2

mkchromecast seems like overkill (python + node.js + ...!) given it's just running ffmpeg underneath. Run ffmpeg, and the cast command above. 1 binary solution for the pi :-)
