[PATCH 0/2] MR5511: winegstreamer: Respond to URI query.

[Brendan McGrath (＠redmcg)]

The default behaviour for gstreamer is to use the URI to create the
stream-id. Without this, gstreamer creates a random stream-id per pad
which can cause inconsistent ordering on the decodebin src pads.

This in turn can cause issues, for example, with audio stream selection.

The first commit is a partial cherry-pick of eda34f74c6ad from Proton.
