Sample description: This command calls the JPEGD, VPC, and JPEGE in sequence. test_type 12 indicates that the user allocates memory. This command calls the JPEGD to decode a JPG image as a YUV420SP image, sends the image to the VPC for cropping and resizing, and calls the JPEGE to encode the VPC output to generate a JPG image.
