[PATCH v4 0/7] MR3528: winegstreamer: Implement windows api frontend for file media sink.

[Ziqing Hui (＠zhui)]

There is a working in progress winegstreamer muxer backend: !3303 
This patch set is the windows api side(frontend) of the muxer stuff.

It will make the patch set too large to submit the backend and frontend together, so I decide to submit the frontend first.
