Q1: Some python sample codeWhat to do if the module can't work normally?
A1: * 1. First the HDMI device should be plugged in and have signal output before the Raspberry Pi is started.* 2.Please check if there is a video related file in the /dev file.* 3. Please provide us more details for us to confirm the issue.a. First please send us your '''order number''' and tell us "Call command" "Input Device" and "Using Device". b. What is the HDMI input device, resolution and frequency? c. Which version of Raspberry Pi you use? d. What is the specific calling command? e. What is the terminal error notification? Q2: Some python sample code A2: The HDMI source supported by Raspberry Pi with the module is 720p/50fps,720p/60fps,1080i/50fps,1080p/24fps,1080p/25fps. Lower resolution is also working.
This is the python code used in my video.The Pi uses an official image with no other changes.

If you want to use your Raspberry Pi for HDMI capture, this is the only device I'm aware of that will do it. Furthermore you can do some powerful things that would normally require equipment costing many hundreds of dollars. For example, using always-on camera preview and a few lines of Python code you can easily do image flipping, rotation, and rudimentary scaling. Note that you can't adjust color or exposure, and audio is not passed through.
This HDMI input module does what I care about (capturing my generic HDMI camera), but it failed at some things that thankfully I didn't need it to do. Your use case may vary so don't be surprised if some HDMI devices don't work with it.
