The best engineering solution to a situation like this is to p/invoke
libavformat etc. from within your C# application. It is theoretically
possible to do this, but although I think it's been tried I'm not sure it
has ever been done successfully (though this information is a year or two
old and may be out of date).
There are some reasonably significant technical challenges. The libraries
concerned talk amongst themselves using a lot of strange datatypes and you
would need to understand these datatypes, how they're arranged in memory,
the calling conventions in use, and so on, as well as the basic
understanding of how the libraries are supposed to work under normal
circumstances in C.
None of this is particularly different to what you'd face trying to
p/invoke any other library, but in this case it's opensource so the
documentation is fairly partial (and I'm being kind there) and you are
likely to face open hostility from the development community who by and
large view anything Microsoft as spawn of the devil.
That said, this is exactly what p/invoke is supposed to be for, to get
native code to do the heavy lifting around a managed framework, and I
would be more than happy to pitch in to any effort to get it working.
