hi_aec_frame

Defines the information about the reference frame for audio echo cancellation (AEC).

As AEC is not supported currently, you can leave this structure empty.

typedef struct {
    hi_audio_frame ref_frame;
    hi_bool     valid;
    hi_bool     sys_bind;
} hi_aec_frame;

For details about basic data type hi_bool, see Basic Data Types.
