void frc::VisionRunnerBase::RunForever | ( | ) |
A convenience method that calls runOnce() in an infinite loop.
This must be run in a dedicated thread, and cannot be used in the main robot thread because it will freeze the robot program.
Do not call this method directly from the main thread.
void frc::VisionRunnerBase::RunOnce | ( | ) |
Runs the pipeline one time, giving it the next image from the video source specified in the constructor.
This will block until the source either has an image or throws an error. If the source successfully supplied a frame, the pipeline's image input will be set, the pipeline will run, and the listener specified in the constructor will be called to notify it that the pipeline ran. This must be run in a dedicated thread, and cannot be used in the main robot thread because it will freeze the robot program.
This method is exposed to allow teams to add additional functionality or have their own ways to run the pipeline. Most teams, however, should just use runForever in its own thread using a std::thread.
