Use shared OpenGL context to avoid the whole device->host->device ping pong

What is the theoretically lowest SDI->SDI throughput latency you can imagine, given GPUDirect etc.?

ronag commented 6 years ago

With black magic, 4 frames

jesperstarkar commented 6 years ago

Any lower, @jamesdwise ?

For the sake of the discussion https://github.com/CasparCG/server/issues/891 - current real-world end to end latency is currently said to be 8 or 9 frames regarding if low-latency is enabled or not.
