I am using Godot Python on Windows 10 64 and I manage to run Open CV in Godot.
I manage to call my webcam and capture frames from it.
However when I try to convert the OpenCV frame to a Godot Image ... the process is timed at about 1 entire SECOND ... to do so I make it a ByteArray and do a Image.CreateFromData ()
Should I use a streamTexture ? Is it possible to attribute it from code instead of a file?
Should I rather write the byte array into the properties of a shader to run faster (use of graphics card)?

Best regards,
