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 
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
Hey guys,
I’ve used this in the past quite successfully to line up things during a shoot. I was wondering, since sparks are no more, if there’s an OFX equivalent for this?
Thanks!
wait what this existed? Live input?
I would absolutelt love this
Too late now. It used to be a spark.
need some time to convert it to OFX
I had no idea this existed. How cool! +1 for a an OFX version.
Yeah… Was really useful during shoot especially. Live keying, aligning things… etc… I’ve used it on my laptop with a BM mini recorder.
looking at assimilate liveFX for that also, dont know if thats a option for doing stuff like that…
