hi_audio_stream

Description

Defines the audio streams.

Prototype

typedef struct {
    hi_u8 ATTRIBUTE *stream;    /* the virtual address of stream */

    hi_u32 len;                 /* stream length, by bytes */
    hi_u64 time_stamp;          /* frame time stamp */
    hi_u32 seq;                 /* frame seq, if stream is not a valid frame,seq is 0 */

Members

Member	Description
stream	Pointer to the audio stream
phys_addr	Physical address of the audio stream
len	Audio stream length (unit: byte). If hi_mpi_adec_create_chn is called to set the decoding mode to the pack mode, this parameter needs to be set to the length of one audio stream frame (stream data length + header length). The maximum length of a stream frame is 16384 bytes. If hi_mpi_adec_create_chn is called to set the decoding mode to the stream mode: When hi_mpi_adec_send_stream is called to send streams in non-blocking mode, the range of the len parameter is (0, 16384]. When hi_mpi_adec_send_stream is called to send streams in blocking mode, the range of the len parameter is subject to the range of the hi_u32 data type but does not include the value 0.
time_stamp	Timestamp of the audio stream
seq	Sequence number of the audio stream. If a stream is invalid, seq is 0.
