Thanks so much for your help, certainly cheaper (and more fun) than the hardware alternatives.
#NANO TELEPROMPTER FOR PC DRIVERS#
So basically 70 euros delivered, and 45 minutes work from scratch and it's working.ĭisplay_hdmi_rotate didn't work for some reason (using the normal drivers too - no idea why?) but then I realised I can add camera.hflip=True and that does it and also leaves the rest of the os the right way so that's fine (better, actually). Better than nothing but not as fast as I'd like!Ĥ0 euros for the HDMI card, 29 for the Zero W kit (could have got cheaper of course). Thanks for confirming what I thought, that a USB card is unlikely to do what I need (although I don't need 1080p, I only need 1366x768 but I do need a full - or at least very good - frame rate). DisplayPlacer is basically XrandR for the mac, but it doesn't have the feature, and SwitchResX is another but that doesn't either. There doesn't appear to be a way to do it on the mac. "xrandr -output HDMI-1 -reflect x" does it for me on a Pi. If running that from a terminal prompt on your Mac gives any sensible output then it may be possible to do it at source. I'm not a Mac person, but seeing as it is related as a Unix/BSD derivative, the Linux command you'd be after is "xrandr". Regarding the Auvidea B101, Mouser have them in stock and I've generally had them in a couple of days when I've ordered from them. Encoding and decoding take time, so increase latency. They can only do 1080p30 when producing MJPEG, so something then needs to decompress that.
I have one in front of me that I analysed on viewtopic.php?p=1696636#p1696636 There was a discussion about USB HDMi Capture Devices like this:
