Members

Member	Description
one_stream_buf	Configuration mode of encoding stream frames. Defaults to 1. 0: multi-packet mode. 1: single-packet mode.
mini_buf_mode	Stream buffer allocation mode. Reserved. Defaults to 1. 0: The stream buffers are allocated based on the resolution. 1: The stream buffer size is 32 KB at a minimum.
low_power_mode	(Reserved) Low-power mode. Defaults to 0. 0: The low-power mode is disabled. 1: The low-power mode is enabled. Note that enabling the low-power mode and the ultra-low-power mode can cause image quality loss.
vb_src	Frame buffer allocation mode for the reference frame and reconstruction frame. Defaults to HI_VB_SRC_PRIVATE. For details, see hi_vb_src. HI_VB_SRC_PRIVATE (default): private VB. The driver internally allocates frame buffers. HI_VB_SRC_USER (reserved): user VB. The frame buffers are allocated by the user.
qp_hist_en	QP histogram output control. Reserved. Defaults to 1. 0: The QP histogram is not output. That is, qp_hist in hi_venc_h264_adv_stream_info is all 0s. 1: The QP histogram is output. That is, qp_hist in hi_venc_h264_adv_stream_info indicates the QP histogram of the current frame.
max_user_data_len	Maximum memory allocation in bytes for user data. Reserved. Defaults to 1024.
