How to make a video capture board?

Question

Electronics

Hello,
can you tell me the frame grabber diy project? I would like to capture video from tulips or hdmi and then stream it over the Internet, but I do not understand where to start. The task does not look unique, but I could not find a single project that ended with a working device.

Answer 1

although this project is made for vga, it may be suitable for you.

Answer 2

I found a couple of open source projects for HDMI:
hdmi2usb (2 HDMI inputs, 1 DisplayPort input. 2 HDMI outputs, 1 DisplayPort output, 1 gigabit Ethernet, USB 2.0 OTG, $349), positioned as a
NeTV conferencing tool (1 HDMI input, one output, microUSB 2.0, WiFi, $150 on Adafruit) - needed to make smart TVs out of ordinary TVs. Developer release discontinued.
NeTV2 is a faster and smarter version of NeTV. 1 input, 1 output, execution - mPCI card. Not yet available from the developer, the estimated price is $200-250.
Well, the classic, cheap and cheerful - plugging a UVC and IR transceiver into the RaspberryPi, it turns out about $60-70, but there is a risk that it won't start.
UPD Found a post by a man who ripped apart an HDMI extender for $40(1 , 2 ). The article is interesting, but the author advises UVC + RPi as an option with better quality for the same money.
