mxpi_imageencoder

Encodes images.

Asynchronous

• Maximum resolution of the input image: 8192 x 8192
• Minimum resolution of the input image: 32 x 32
• The width and height of the input image must be even numbers. If they are odd numbers, they are automatically aligned to even numbers.
• widthStride of the input image (width after alignment): For the YUV420SP or RGB data, round up widthStride to the nearest multiple of 16 or 128 (for better performance). For YUV422Packed data, round up twice the input width to the nearest multiple of 16.
• heightStride of the input image (height after alignment): Retain the input height. Alternatively, round up the input height to the nearest multiple of 16 (at least 32).
• Input image formats: YUV420SP (nv12 and nv21), YUV422Packed (yuyv, uyvy, yvyu, vyuy), and RGB (rgb888, bgr888)
• Input data type: Currently, only UINT8 is supported.
• Output image format: JPEG, for example, *.jpg

• Input: buffer (data type: MxpiBuffer), metadata (data type: MxpiVisionList, MxpiFrame, or MxpiVision)
• Output: buffer (data type: MxpiBuffer)

• Static input: {"ANY"}
• Static output: {"ANY"}

deviceId

Ascend device ID, which is specified by the deviceId property in the stream_config field. You do not need to set the ID.

No

Yes

dataSource

Index of the input data (generally the name of the upstream element). The default value is the key value of the output port of the upstream plugin.

No

Yes

encodeLevel

Encoding level.

• For the Atlas 200/300/500 inference product, the default value is 0, and the value range is [0, 100].
• For the Atlas 200I/500 A2 inference product, the default value is 100, and the value range is [1,100].
• For the Atlas inference product, the default value is 100, and the value range is [1, 100].
