Chose audio device

[Miguel Leão]

Thanks Tim and Nicolas!
With the gst-device-monitor-1.0 Audio/Sink command I was able to figure it out.

I am using the pipewiresink, I figured I had to use the path flag. But the thing is, when I ran "pw-cli list-objects" command I saw that it each device has id, name, and path. So I was using the path from the device, to set the path flag, but it is the id that needs to be used.

Hi,

I have a computer with 4 HDMI outputs, and I want to chose from which to play audio. How can I do that?

A generic way to list available audio devices is the GstDeviceMonitor API.

You can check the available devices you would get with that via

gst-device-monitor-1.0 Audio/Sink

and the output should also contain something you can paste into a gst-launch pipeline.

In an application you would use gst_device_create_element() instead on a device that you get via the device monitor API.

Cheers
 Tim
