fn set_cbr_rate(rc: &mut NV_ENC_RC_PARAMS, bps: u32, vbv: u32)Expand description
Write a CBR target into rc: the average and peak rate, the VBV, and an initial delay of the
whole buffer. That delay is the driver’s default (gpu_bench_cbr_policy finds the two
identical), stated so the HRD’s starting point is explicit and a rate change restates it
with the buffer it belongs to.
