VideoEncodeConfig

width

int

Width of the encoded video frame data. The default value is 1920. The value must be the same as the width (original_width) of the image to be encoded.

• For the Atlas 200/300/500 inference product, the value ranges from 128 to 1920, and the input video width must be a multiple of 16.
• For the Atlas inference products, the value ranges from 128 to 4096, and the input video width must be a multiple of 2.

height

int

Height of the encoded video frame data. The default value is 1080. The value must be the same as the height (original_height) of the image to be encoded.

• For the Atlas 200/300/500 inference product, the value ranges from 128 to 1920, and the input video height must be a multiple of 2.
• For the Atlas inference products, the value ranges from 128 to 4096, and the input video height must be a multiple of 2.

outputVideoFormat

StreamFormat enumerations

Output video format after encoding. The default value is base.h264_main_level.

inputImageFormat

image_format enumerations

Input image format. Only base.nv12 (default) and base.nv21 are supported.

keyFrameInterval

int

Video I-frame interval. The default value is 30, and the value range is [1, 2000].

srcRate

int

Frame rate of input streams, in fps. The default value is 30.

• For the Atlas 200/300/500 inference product, the value ranges from 1 to 120.
• For the Atlas inference products, the value ranges from 1 to 240.

rcMode

int

maxBitRate

int

Output bit rate, in kbit/s. The default value is 300.

• For the Atlas 200/300/500 inference product, the value ranges from 10 to 30000.
• For the Atlas inference products, the value ranges from 2 to 614400.

ipProp

int

I-frame to P-frame bit allocation ratio within a GOP. The value ranges from 1 to 100 and defaults to 70.
