run in cuda and args

[luoww1992]

params.effect = EFFECT_NONE;
params.device = "CPU";

params.cpu_threads_num = 0;
params.cpu_bind_thread = true;
params.cpu_throughput_streams = 1;

params.is_async = false;
params.interval = 1;
params.threshold_motion = -0.1f;

i run it in win10 cpu,
And,
can you tell me the args meaning?
when i use it to run HD video ，it is slow, and cuda is not used when params.device = "GPU";
only run it in intel gpu?
