Hi guys,
My project is capture two 1080p SDI signals and render them in one VMR window(based on DirectShow framework), it works very well with "DeckLink Duo", but I can't get it from my supplier any more, they only have "DeckLink 4K Extreme". I checked the spec of 4K extreme, it has two channels chA and chB, so I thought it will be very eazy to compile the new card, but I found it not eazy after I bought the new one.
First, let me expaint my project before.
"DeckLink Duo" have two devices in DirectShow's source filter:
"Decklink Video Capture"
"Decklink Video Capture (2)"
so connect the output pins of both source filter to VMR filter, and do some configuration, it works very well.
"DeckLink 4K extreme" have two devices in DirectShow's Video Capture Sources:
"Blackmagic WDM Capture"
"Decklink Video Capture"
But both them only can show one signal (channel A). So I began to try Media Express, I change configuration of "Edit"->"preferents", still have only one signal in capture window.
I read SDK "Blackmagic_DeckLink_SDK_10.3.1", found that 4k extreme have 3D capture function, so i tried to modify sample "CapturePreview" follow SDK pdf 2.4.3.1, unfortunately, I failed.
After that I checked all DirectShow Samples in SDK 10.3.1, nothing about "3d capture" or "4k extreme", is that mean 4k extreme no longer compatible with DirectShow?
I'm out of juice, any one have same experience? is it possible to capture dual signals with 4k extreme in DirectShow framework? Any suggestion?
Thanks for your time.
Best Regards:
Cody
