Member	Description
bg_interval	Interval of long-term reference frames. Value range: [gop, 65536]. The value must be an integer multiple of gop. gop indicates the interval of the I frames.
bg_qp_delta	QP delta of long-term reference frames relative to P-frames. Value range: [–10, +30] In the debugging information, this parameter is equivalent to ip_qp_delta in other bit rate control modes.
vi_qp_delta	QP delta of virtual I-frames relative to common P-frames. Value range: [–10, +30]

Description

bg_interval

Interval of long-term reference frames.

Value range: [gop, 65536]. The value must be an integer multiple of gop. gop indicates the interval of the I frames.

bg_qp_delta

QP delta of long-term reference frames relative to P-frames.

Value range: [–10, +30]

In the debugging information, this parameter is equivalent to ip_qp_delta in other bit rate control modes.

vi_qp_delta

QP delta of virtual I-frames relative to common P-frames.

Value range: [–10, +30]
