Support for Blackmagic WDM Device

[flat-eric147]

Hi all,

first of all great library! I experimented a little bit and found an issue with the infinite pixel formats that are out there. I am testing with a BlackMagic SDI input card, their driver includes a DirectShow filter (Blackmagic WDM Capture). It did not work out of the box, so I checked with the debugger and added a fourcc code:
HDYC = 0x43594448
which is basically "PixelFormats.UYVY". So adding a few more switches around the code worked for me.
I forked the repos and pushed my mods here:
https://github.com/flat-eric147/FlashCap
Would be great if this little patch could make it into the main repos!

@flat-eric147 Thank you reaching out FlashCap!

I don't have BMSDI, but that means the format is fine with UYVY, so I will merge it when I review it!

Merged.
