inputDesc

Pointer to the input image description.

• Call acldvppCreatePicDesc to create an image description.

outputDesc

Input/Output

Pointer to the output image description.

When outputDesc is used an input, the user needs to:

• Call acldvppCreatePicDesc to create an image description.
• Call acldvppSetPicDesc series to set the image description (including the buffer address, buffer size, image format, and image resolution).

  You must specify the width, height, width stride, height stride, buffer address, buffer size, and format of the output image.

  • The width and height of the output image must be the same as those of the input image. Otherwise, an error is reported.

    If the width or height of the output image is set to 0, VPC uses the width and height of the input image as the width and height of the output image respectively. In addition, VPC calculates the width stride and height stride based on the alignment requirements, which vary with the image format. For details, see Restrictions on Image Formats, Width and Height Alignment, and Buffers.

  • The width stride and height stride of the output image must meet the alignment requirements, which vary with the image format. For details, see Restrictions on Image Formats, Width and Height Alignment, and Buffers.
