Hi, I ordered one of these: https://smile.amazon.com/gp/product/B089CR8S8K/ and it's recognized and works OK, but the frame rate seems a bit slow in OBS-Studio compared to what I'm seeing from my Logitech C930e cam. I decided to test on a Windows PC I happened to have and didn't see the issue, so it seems to be a driver issue or some other sort of setting issue. Comparing the two devices in usbconfig show_ifdrv, I see this for the Logitech: ugen0.8: <vendor 0x046d Logitech Webcam C930e> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA) ugen0.8.2: uaudio0: <vendor 0x046d Logitech Webcam C930e, class 239/2, rev 2.00/0.13, addr 20> and this for the HDMI capture: ugen0.9: <MACROSILICON product 0x2109> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA) ugen0.9.2: uaudio1: <USB Digital Audio> ugen0.9.4: uhid0: <MACROSILICON product 0x2109, class 239/2, rev 2.00/21.00, addr 21> The only other difference I see is that looking at sysctl output I see this for the Logitech: dev.pcm.10.rec.vchanrate: 48000 and this for the HDMI capture: dev.pcm.11.rec.vchanrate: 96000 Any suggestions or ideas? Thanks, Steve
