I need help .
I have a Datapath E1S in in a Core i9 9900K base machine (Gigabyte Z390 AORUS MASTER motherboard) with 64GB RAM and a Geforce RTX 2070 running under Windows 10 Pro
The card is inserted in the second PCI Express x16 physical slot, which maxes out at x8.
E1S is currently running at PCI Express 1.1 x4 (as confirmed by HWINFO)
I keep getting bursts of inserted frames. Whether I am capturing from a Geforce FX 5900 DVI at 1600x1200@70HZ, a Voodoo 3 running at 1280x800@70Hz through OSSC (line doubled 640x400@70Hz) or a Voodoo 3 running at 1280x960@60Hz through OSSC (line doubled 640x480@60Hz) . This happens regardless of whether I set the E1S to YUY2 or RGB32 (setting to RGB24 gives a garbled mess).
i am capturing using Virtualdub2 (latest build, but tried an older one too) using FFMPEG HUFFYUV codec in RGB mode .
I have tried setting framerate to the fractional values that the VCS detects (i.e. 70.08Hz), but that changes nothing (I still get bursts of inserted frames) .
The kicker is that, if I capture using a Cam Link 4K USB device, I get perfect results (no frames lost or inserted), but am limited to YUY2 .
I have tried both the most recent driver and the previous release of the E1S driver .
Does anybody have any ideas ?
In desperation, I am about to try capturing under Linux .
EDIT : I doubt that this will change anything, but I have a an Ezcoo brand 3x2 HDMI switch and splitter on the way . i will try with that once I receive it .
