What are the libraries for viewing non-standard video and audio formats in Windows RT (Windows Store apps)?

Question

.NET

I'm currently working on a media player project for the Windows Store. I really wish users of this media player could play as many video/audio formats as possible (like mkv/flv/flac). Alas, a Google search turned up nothing. I looked in the Windows Store - there are such applications. I decompiled some of them - and alas, I did not find components that can be used, because they were written by the companies that developed these players.

So, what about the current situation regarding video and audio playback in the Windows Runtime? Is there some kind of library or something else? Maybe there is a semi-finished solution that can be finished in a couple of days of work? It may be possible to convert mkv / flv to a supported format in the application itself (i.e. the transcoding process must take place in the application itself).

All I found in the great Google is “yeah, it's possible; no, I don't know a quick way." Alas, writing your own decoder will take too much time.

Answer 1

Maybe I'll write nonsense, but nevertheless:
What prevents you from building libav under win rt? The fact that it is under lgpl and the finished program cannot be published in the Windows Store?

Answer 2

so there seems to be a bunch of libraries like mpeg that can play almost everything in a row, look in this direction ...
