Hi, Could you tell me the camera model you used to test the decoding under Ubuntu？ Thanks!

How to compile a project on Windows？

The camera I'm testing with is a Razer Kiyo Pro. Any 1080p camera could work, though it is a bit difficult to get it set up right. cimbar_recv has rough edges...

The requirements are:

• a 1080p webcam -- on linux, test with cheese or obs-studio, or ...
• enough usb bandwidth to maintain 1080p. This can vary by usb port (ex: USB3 vs USB2).
  • some USB-C hubs have given me issues -- making it necessary to drop the capture resolution down to 720p or 480p. Since cimbar needs ~1000 pixels of vertical resolution, 1080p is essential.
  • this can be verified with cheese or other camera apps
• figure out what video device your camera is plugged in on. This can be done with v4l2-ctl --list-devices (apt install v4l-utils)
  • linux camera devices will be of the form /dev/video0, /dev/video1
• run cimbar_recv: ex: ./cimbar_recv -i /dev/video2 -o /tmp
  • point the camera at a cimbar feed!
  • your enemies are autofocus, glare, shaky hands, etc.

As for Windows builds -- unfortunately, it's not likely right now. One day, perhaps, but there will need to be changes, and I don't use Windows these days (so testing will be difficult on my end).

What is the transmission rate of the Razer Kiyo Pro camera on Linux

What is the transmission rate of the Razer Kiyo Pro camera on Linux

The camera itself is 60fps at 1080p (which is why I bought it), but as for cimbar transfer speeds on linux -- I don't know! My android tests have been focused on performance, but the linux tests are still in the "how well does this work?" phase.

I will say that it's more difficult to hold the image steady on a webcam (compared to a phone) -- and based on my tests, autofocus is a menace (the native app probably should have manual focus options).
