Description

Encodes a YUV image into a JPG image. This API is asynchronous.

Prototype

aclError acldvppJpegEncodeAsync(acldvppChannelDesc *channelDesc,
acldvppPicDesc *inputDesc,
const void *data,
uint32_t *size,
acldvppJpegeConfig *config,
aclrtStream stream)

Parameters

Parameter	Input/Output	Description
channelDesc	Input	Pointer to the channel description. Must be the same as the channelDesc argument passed to the acldvppCreateChannel call.
inputDesc	Input	Pointer to the description of input images. Call acldvppCreatePicDesc to create an image description. Call the acldvppSetPicDesc series to set the image description (including the image format and image resolution). For details about the requirements on the input image resolution (≤ maximum channel width × maximum channel height) and image format, see Functions and Restrictions.
data	Output	Pointer to the output buffer address for storing encoded data.
size	Input/Output	Pointer to the output buffer size in bytes. When size is used as an input, call acldvppJpegPredictEncSize to estimate the output buffer size in advance. When size is used as an output, it indicates the actual output buffer size, which may be different from that estimated by the acldvppJpegPredictEncSize call. The actual output buffer size should apply.
config	Input	Pointer to the image encoding configuration. Call acldvppCreateJpegeConfig to create an image encoding configuration, and call acldvppSetJpegeConfigLevel to set the encoding configuration.
stream	Input	Stream.

Returns

0 on successful task delivery; else, failure. For details, see aclError.
