Member	Description
type	Audio decoding protocol type. Currently, only HI_PT_G711A, HI_PT_G711U, and HI_PT_AAC are supported.
buf_size	Size of the audio decoding buffer, in frames. For G.711a and G.711u decoding, the value range of this parameter is [2, 100]. For AAC decoding, the value range is [10, 80].
mode	Decoding mode For G.711a and G.711u decoding, the stream and pack decoding modes are supported. For AAC decoding, only the stream mode is supported.
value	Pointer to the specific protocol attribute. For G.711a and G.711u decoding, the value of this parameter is invalid and can be any non-null pointer. For AAC decoding, the hi_adec_attr_aac structure variable must be passed. This is a static attribute.
