Understood Nicky - thanks for the insight. Messages here as well as some digging I've done today suggest that trying to make GStreamer work on Windows is going to be fraught with technical and legal issues.
I'll double check with the legal team but it seems like VLC might be a more viable option right now given our limited resources. Great idea re: CEF too - that'd be a huge win. Building Chromium then CEF with the flags enabled seems pretty daunting though and I think requires some serious hardware/RAM - has anyone tried that ?
