Two program run two device in same pc problem
I'm trying to use the same program to control different devices by specifying a different index, like this:
ctx = Context() self.device_list = ctx.query_devices() self.device = self.device_list.get_device_by_index(0) self.pipeline = Pipeline(self.device)
My program can run directly on different devices. However, I can't run two programs simultaneously. I don't get any error messages when running the programs.
Let me explain in more detail. I have two identical programs, named A_program and B_program, and two Femto Bolt cameras, named A_camera and B_camera.
It works when I use A_program to get data from A_camera. After I stop that program, I can run B_program to get data from B_camera, and that also works.
However, when I run both programs simultaneously, I only get data from the first program that was opened. For example:
Run A_program -> Run B_program -> only A_program gets data.
It seems running example/two_devices_sync.py can work.
Why does this happen? How can I use two different programs to control different cameras on the same PC?
You could try something like this: self.device = self.device_list.get_device_by_index(device_index)
By changing the device index, you can run different devices in different programs on the same PC. By default, get_device_by_index(0) always selects the first camera in the device list. Changing the index allows different programs to control different cameras.
