Stream to Playback Devices with Different Capabilities

[simoncn]

Multiple instances of MinimServer are supported natively on Linux and by Docker containers on QNAP. The Docker solution also works (unofficially) on Synology.

This is a common user request and I wish there were a better solution. The main issue is that the UPnP protocol requires the server to specify the audio format and resolution of the stream without knowing what renderer will be used to play the stream. The server can offer multiple alternative streams with different audio formats and resolutions and MinimServer/MinimStreamer fully supports this. The UPnP protocol allows the control point to select one of these alternative streams based on the capabilties advertised by the renderer but unfortunately most control points do not provide support for this.
