[FFmpeg-devel] Notes about avdevice

What I do is run ffmpeg.exe and parse the output. Crude, but works,
and yes, you can run commands from within GUI's :)

See above.

Alternatively, you could enumerate the dshow devices yourself:

or copy and paste the code from dshow*.c into your own program to be
able to enumerate all the various types, etc (if you wanted to avoid
the overhead of startup time calling to ffmpeg.exe).
GL!
