Field Documentation

unsigned int feature_enable

this is a bit combination. If you want to involve watermark, then feature_enable |= DVR_ENC_H264_WATERMARK.

DVR_ENC_ENHANCE_H264_RATECONTROL

DVR_ENC_MJPEG_FUNCTION

DVR_ENC_H264_WATERMARK

DVR_ENC_ROI_POS

Definition at line 81 of file dvr_enc_api.h.

unsigned int target_rate_max

for New rate control

ECBR: usually stays at target bitrate,

produce large bitrate when big motion, but never more than max bitrate

Definition at line 85 of file dvr_enc_api.h.

unsigned int reaction_delay_max

max frame count will the rate-control stay when away from the target bitrate, only valid at ECBR

Definition at line 87 of file dvr_enc_api.h.

int enc_type

for MJPEG

EncodeType_tag

Definition at line 90 of file dvr_enc_api.h.

int MJ_quality

Motion JPEG quality.

1(worst) ~100(best)

Definition at line 92 of file dvr_enc_api.h.

int watermark_enable

for H264 Water Mark

Indicate watermark enable or not

if 0: disable,

if 1: enable, but only insert watermark at intra-mb,

if 3: enable, and insert warermark at intra/inter-mb,

if others: not allowed

Definition at line 99 of file dvr_enc_api.h.

int watermark_interval

specify the interval, to insert watermark each "interval" frame,

valid when watermark function is enabled,

if 1: will be inserted watermark each frames,

if N: will be inserted watermark each N frames

Definition at line 104 of file dvr_enc_api.h.

int watermark_init_pattern

The initial pattern for watermark

valid when watermark function is enabled

Definition at line 107 of file dvr_enc_api.h.

int watermark_init_interval

specify the interval, to reinit with init_pattern each "watermark"ed frames

valid when watermark function is enabled

if 1: every "watermark"ed frame with init_pattern

if N: initial with init_pattern each N "watermark"ed frame

Definition at line 112 of file dvr_enc_api.h.

POS roi_pos

for ROI x, y position

Definition at line 114 of file dvr_enc_api.h.
