We are still in a situation where working from home is the normal situation.
And while maybe you already got enough webcams to solve your conferencing problems, here are two new ideas.
A HDMI capture card was always something I dreamed of but 120 € was too much to just play around with it.
Now, the price has changed.
There are currently some new chinese, no-name capture cards on the market for as low as 15 €!
Yes! They are able to capture HDMI at 1920x1080 with 30fps and only a short delay. If you lower the resolution, you even get 60fps.
And what's best about them, you plug them in as USB device and they pretend to be a webcam.
No additional drivers needed.
Just search on amazon for "HDMI capture card" and you'll find them.
There are even once with a HDMI output to connect an additional monitor.
Glad you ask ;-)
With a HDMI Capture Card, you can...
Isn't that cool?
In my last blog posts, I tried to set up a pizero based webcam, but it needed to many additional drivers and the performance varied over the network.
I didn't think of the feature that the pizero (and only the pizero, no other model yet) can act as an usb device itself.
But now I found a great blog post which desccribes exactly this: turn the pizero in a usb webcam.
Since modern operating systems already include drivers for webcams, no additional drivers are needed.
The results as presented in the video from the blog author look very promising:
Now, this will allow me to create an IR-Webcam with th PiNoIR camera - that'll be fun!
