attr: dict, dictionary of the decoding channel attributes. For details, see hi_vdec_chn_attr.

ret: int, error code.

• 0 indicates success.
• Other values: failure. For details, see VDEC/JPEGD Return Codes.

• Ensure that a channel has been created. Otherwise, the error code HI_ERR_VDEC_UNEXIST is returned.
• Among the attributes, only the following are configurable: type, mode, and ref_frame_num. The value of type can only be HI_PT_H264 or HI_PT_H265.
