Hi All, I have just seen (probably I am few years late ) on YouTube a short video on D1 hardware device for SGI enabling to run Linux modern apps. Do you know if this device is really coming? thanks, m.
What model of Magewell capture device are you using?My personal goal -- once I have more time to devote to all this -- is just to make sure I can transparently use one keyboard/trackball and one set of monitors to control both new and old machines. I'm aware of Synergy / Barrier but I would like to arrange for some sort of solution that is more hardware oriented and works during machine boot as well.
Currently I have retro machine desktops displaying through a modern iMac (with a three display arrangement) via a Magewell capture device; the video latency is not good enough for games, but quite suitable for everything else. However, I still have to use a separate PS/2 keyboard and mouse. I have some thoughts on how to solve that, but not enough time to dedicate at the moment
Regarding input lag, I don't have a good way to quantify it but I would say "enough so that a mouse pointer trails only slightly behind." Works fine for regular text and GUI, but not sure I'd want to try and play an FPS through it just due to reaction time issues. At that point you might want to duplicate the signal to both a monitor and capture device.Can multiple USB Capture (Plus) cards be connected to one computer?
Yes. However, you need to make sure that each card is connected to an independent USB 3.0 extensible host controller, so that sufficient bandwidth can be guaranteed. You can check the number of independent USB 3.0 extensible host controllers available on your computer in device management.
Thanks!Ah, see: https://forums.sgi.sh/index.php?threads/sgi-video-capture-with-magewell-usb-capture-dvi.91/
Works with DVI, HDMI, and analog video inputs. It does support Sync on Green for analog inputs, though you have to play with the settings a little bit (timing & color space?) so it doesn't turn pink in the PROM, for whatever reason. Always works great either way once booted into the OS though even without any settings changes. Very flexible and gives good stats back on what the video signal is through the control panel app.
