Hi,
I am looking for some help, as I am stuck.
I have a Raspberry Pi 5 with two PiCam 3 cameras. I am trying to stream from both cameras, as I want to be able to use either one or both from a web browser. Which is why I was looking at the code below.
I have used the following code, which is direct from the samples:
And edited and changed it ad infinitum. I can get either camera 0 or camera 1 to stream, but I cannot get them to stream together. The solution doesn't need to be based of of this code, it is just where I was working.
I have tried running the code twice, in two different windows and only one seems to work. In the double experiment, I had different ports and used the correct camera.
Your help and suggestions would be much appreciated.
Thanks
Katie
