Can't run the program

[Anominious]

when i run the program, it took like a split of a second. Then it said in the command center,
"Process finished with exit code 0" the camera was not turning on, nor the program. What should i do to fix it?

[Anominious]

Never mind, the program is running, however, when the camera is on, it auto quits if I press b , as the instruction say, does anyone know y?

Pressing the 'b' key closes the program. and I get this error:

some idea to solve it.
Thanks,

Hi @getvladimir4 try using createBackgroundSubtractorMOG2 instead of BackgroundSubtractorMOG2

Still same error. Any other way to rectify this?
