i know Visualjockey can do it and any other software that fully supports freeframe should be able to do it, thru the Bigfug’s fugstream plugin(freeframe), search it on the forum. btw… don’t expect miracles regarding performance/resolution and from my experience it’s not a very easy, reliable and userfriendly way to do it.
black magic : never tried with vvvv but heard about its aquisition power. it doesn t work ?
no network feature for blackmagic. about network thing is it possible to imagine a H264 plugin coding the stream before sending to udp, and a h264 decoder plugin ? i have the filling it could fit the bandwith on 1000 Mb cards
vhscrap is nioe but on heavy complex project something is colliding in memory with vvvv
A very simple way I use to capture video from another window on the same computer is Screenshot (EX9.Texture). This usually brings high framerates around 60fps (as long as you stay on the same screen output - think dual-/triple-head). I have used this in a live setup with up to 4 seperate inputs - works smoothly.
The downside is that you need non-DirectX-output on the source window and if you are on XP or have Aero disabled in Vista or Win7 other windows may come in front of your source window. With Aero you can put your window behind other windows and it will still record.
Blackmagic Intensity pro is a great card for capturing HD video. The only limitation that I don’t like is that it only supports HD resolutions as input from another computer, IE 1280x720p or 1920x1080p. If you can work with that, it is fast, great quality, and not that expensive.
