C Prototype

        
             uint32_t acldvppGetPicDescRetCode(const acldvppPicDesc *picDesc)

Python Function

        
             ret_code = acl.media.dvpp_get_pic_desc_ret_code(dvpp_pic_desc)

Parameters

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

Return Value

Return Value	Description
ret	Int, error code. 0 on success; else, failure. During VDEC decoding, you need to call the acl.media.dvpp_get_pic_desc_ret_code API to obtain the ret_code return code to determine whether the decoding is successful. If the decoding fails, locate the fault based on the return code in the log. For details about the return code, see Return Codes. Some return codes in ret_code are defined in hexadecimal format. If a user prints the return code value (for example, 65540) in decimal format during encoding, the value must be converted to a hexadecimal number (for example, 0x10004) before being queried in Return Codes.
