Obtains the image description parameter: return code.
Input Description
dvpp_pic_desc: int, pointer address of the image description.
Return Value
ret_code: int, return code.
0: success.
Other values: 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 result 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 result codes in Return Codes.
