Members

Member	Description
one_stream_buf	Frame mode select. 0: multi-packet mode 1 (default): single-packet mode
mini_buf_mode	Stream buffer allocation mode. Reserved. 0: The stream buffers are allocated based on the resolution. 1 (default): The stream buffer size is 32 KB at a minimum.
low_power_mode	Power saving enable. Reserved. 0 (default): power saving disabled 1: power saving enabled 2: ultra power saving enabled. Note that enabling power saving or ultra power saving can cause image quality loss.
vb_src	Frame buffer allocation mode select for the reference frame and reconstruction frame. 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. 0: The QP histogram is not output. That is, qp_hist in hi_venc_h265_adv_stream_info is all 0s. 1 (default): The QP histogram is output. That is, qp_hist in hi_venc_h265_adv_stream_info indicates the QP histogram of the current frame.
max_user_data_len	Maximum memory allocation in bytes for user data. Reserved. The default value is 1024.
