             uint32_t acldvppGetPicDescRetCode(const acldvppPicDesc *picDesc)

Python Function

        
             ret_code = acl.media.dvpp_get_pic_desc_ret_code(dvpp_pic_desc)

Parameter Description

Parameter	Description
dvpp_pic_desc	Int, pointer address of the image description.

Return Value Description

Return Value	Description
ret	Int, error code: 0 on success; else, failure. During VDEC decoding, call acl.media.dvpp_get_pic_desc_ret_code to obtain the ret_code return code to check the decoding result. If the decoding fails, locate the fault based on the return code in the log. For details about the return codes, see Return Codes. Some of the ret_code return codes are defined in hexadecimal format. If you want to print the return code values in decimal format (for example, 65540) during encoding, convert the return code values into the hexadecimal format (for example, 0x10004) in advance and then query the return codes in Return Codes.
