What is the lowest latency I can get?

PostFri Apr 23, 2021 10:08 am

Hi, I am working on a monitoring app - I need to display incoming HD video on the screen. No processing, no recording,.. What is the lowest latency I can get with DeckLinks? What is the proper hardware configuration? What is the fastest way to get the incoming frame on screen?
1. Windows or Mac?
2. Thunderbolt with PCIe chassis or standard PCIe
3. CPU: min. i7 or higher?
4. Datapath: incoming video frame -> OpenGL/Metal?
5. What are your numbers for 8bit and 10bit YUV 1080i50, p50?

As far as I know, it could be 3frames, theoretically ...
I couldn't get below 6 frames.

Thank you.
