HDMISpark for Linux

Hi all.
Here is a quick and dirty Linux version v001 of @Lewis Saunders HDMISpark for live video from Blackmagic Decklink devices (cheap Decklink SDI Micro M2 working ok).
Source and compiled binary there.

For compilation need to install / use devtoolset-7 (gcc/g++/clang/llvm) because of broken cvtss_sh in gcc 4.8.5

For testing purposes 25fps mode changed to 50i. Later there should be manual BMDmode selector and input mode indicator.

Nice!! I haven’t been around a linux flame with a BMD card long enough to do this, looks like it was mostly a matter of include paths?

Using 50i is probably a good shout, I think there’s a lot of SDI out there which is PsF rather than true progressive :+1:

it was some changes/additions in includes, adding BMD include path and main hassle was struggle with broken cvtss_sh inlines
next task - using autodetection feature in DeckLink, and maybe using continous update to get live stream without play button pressed
