How to check whether this module is driven correctly?
step1. Check this module if be driven?
After connecting all the cables, power on the Raspberry Pi, the C779 indicator light is normally green, and after opening the Raspberry Pi terminal, enter the following command:
then check if video0 appears. If it appears correctly, it means that the module has been successfully driven and is working normally.
Please try the following oreration if you can't find 'video0'
step2. update & upgrade the raspberry pi system (It may be necessary to update the software source according to your country, and this will take a long time)
sudo apt-get update sudo apt-get upgrade
step3. Open camera module via raspi-config command;
Enable camera & reboot the raspberry pi.
step4: goto step1
step5: if you still can't find 'video0' file in the /dev path, please try the following methods:
A: Confirm whether the HDMI input device has a signal, (you can test whether it is displayed normally by connecting to the screen)
B. Confirm whether the resolution and frame rate of the HDMI input device are below the maximum input resolution and frame rate(720p50\720p60\1080i50\1080p25);
C: We recommend that you download the lastest official image of Raspberry pi if you still don't solve your questions. Download URL: https://www.raspberrypi.org/downloads/raspberry-pi-os/

Q1: What to do if the module can't work normally?
- 1. Please use monitor to test, DO NOT use VNC.(Customer Feedback: During the VNC it spend some of gpu and there is not enough for camera.Based on RPi 4 + Hawkeye Firefly Mini)
- 2. First the HDMI device should be plugged in and have signal output before the Raspberry Pi is started.
- 3. Please check if there is a video related file in the /dev file.
- 4. 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.
from picamera import PiCamera from time import camera = PiCamera() camera.start_preview() sleep(1000) camera.stop_preview()
Q3:Customer Feedback 1 for your reference(https://www.amazon.com/gp/product/B0899L6ZXZ#customerReviews)
A3: 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.
I've tried this with a variety of HDMI devices; half of them work perfectly, half of them don't work at all.
Things that worked just fine:
- GoPro Hero2
- Generic no-name HDMI camera
- OREI HD-102 1x2 HDMI splitter with a Google Chromecast attached to it (but see below)
There's a downside, though. I could not get any of these to work:
- Canon 6D, which causes a "PiCameraMMALError: Failed to enable connection: Out of resources" error
- Blackmagic ATEM Mini, which produces a scrambled picture
- Google Chromecast, because I don't think this device supports HDCP; but it works fine if you strip off the HDCP.
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.
Q4: Will this work with i2s hats such as hifiberry amp2?
A4: Since this item don't use any GPIO, so we think that it can work with I2S hats.
