Thinking off the top of my head... a user could stream with their devices, a priori, and you capture observed user agent strings. Then, assuming they differ between, say, Android and appliances (like AVRs), you present a transcoding choice for a given user-agent (and a default for everything else).

This doesn't work because the stream details (including audio info such as 24-bit WAV) need to be sent to the control point when the control point issues a Browse request. At this point, the server doesn't know which renderer the control point will use to play the stream.

You would know better, but at some point, the renderer and the server have to handshake, because it's the renderer that accepts the socket request from the server. That's when the stream transcoding decision could be made, based on a setting from the user in Minim, not while the control point is negotiating with the renderer and the server.

Unless you can get bubbleguum to makes changes to BubbleUPnP to accommodate selecting streams on-the-fly, that seems like a tough approach.

From a UX standpoint, you don't want users to have to manage this whenever they listen to music - they want to set it from the server and have it work the same way every time for a given server/renderer combination.
