dshow_capture.h sets up various flags before including windows headers
this must occur before other headers (like os_support.h) include these

Keep the code as similar as possible across the codepaths to
ease spotting it for factorization.

Based on a patch from Michael Niedermayer <michaelni@gmx.at>.

The code currently set the information in at least 4 places, spare
some pointless loops.

Make the code in the loop a little uniform to make easier factorize
it out later.
