hi_venc_h265_mod_param

0: The stream buffers are allocated based on the resolution.
1: The stream buffer size is 32 KB at a minimum.

Description

Defines the H.265E module parameters of VENC on the device.

Members

Member	Description
one_stream_buf	Int, configuration mode of encoding stream frames. 0: multi-packet mode. 1 (default): single-packet mode.
mini_buf_mode	Int, configuration mode of the stream buffer, reserved. 0: The stream buffers are allocated based on the resolution. 1: The stream buffer size is 32 KB at a minimum.
low_power_mode	Int, low-power mode, 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	Int, buffer allocation mode 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	Int, 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	Int, maximum memory allocation for user data, in bytes, reserved. Defaults to 1024.
