1

Hi. I am high-school student working with BPI-f3 for science fair project. I used Rasp Pi earlier for another fair with hdmi video capture card. it worked fine. But, Banana Pi does not work, neither on Linux nor Windows. I am using obs with the option of Video Capture Device (Pipewire Beta) or V4L2 or on windows Video capture device. Any way to fix this? Or is this hardware limitation? Using Bianbu OS

Using BananaPi 4Gb ram and 16 GB on board storage version.

Thanks in Advance.

What’s your hardware setup? are you capturing video from the on-board HDMI connector, using an external HDMI device connected to another system? or are you attaching a HDMI decoder connected to your F3? If the latter, are you connected over PCIe or USB? FWIW, I am using an USB HDMI decoder and display the F3 video outputin a window on my desktop, which is more convenient than using a separate monitor.
