返信先: Adding new UPnP renderer to device list issue

[storaid]

Hello, Tiki

This is my thought, please take it into consideration:

Some UPnP devices will change the listening port of their service endpoints during startup. However, under normal circumstances, these devices should continue to send NOTIFY SSDP packets to inform the control endpoint, like TuneBrowser, that the listening port of the service endpoint has changed.

This behavior is indeed possible with some UPnP devices.

Unless the control endpoint continuously monitors changes in NOTIFY packets to update the current device list, the only way is to wait for the UPnP device to complete startup, then start the control endpoint (such as TuneBrowser) to re-detect the UPnP device.

By then, the NOTIFY notification obtained from the UPnP device will already be the service endpoint currently in use.
