Obtains an encoded audio stream.

hi_s32 hi_mpi_aenc_get_stream(hi_aenc_chn aenc_chn, hi_audio_stream *stream, hi_s32 milli_sec)

Parameter	Input/Output	Description
aenc_chn	Input	Encoding channel ID. The value range is [0, 6).
stream	Output	Obtained audio stream.
milli_sec	Input	Timeout interval for obtaining data (ms). -1: blocking mode. The wait is infinite if there is no data. 0: non-blocking mode. An error is returned if there is no data. > 0: A specific timeout interval needs to be configured. If no data is found after the specified interval, an error is returned.

Parameter

Input/Output

Description

aenc_chn

Input

Encoding channel ID. The value range is [0, 6).

stream

Output

Obtained audio stream.

milli_sec

Input

Timeout interval for obtaining data (ms).

-1: blocking mode. The wait is infinite if there is no data.
0: non-blocking mode. An error is returned if there is no data.
> 0: A specific timeout interval needs to be configured. If no data is found after the specified interval, an error is returned.

A stream can be obtained only after a channel has been created by calling hi_mpi_aenc_create_chn. Otherwise, an error code indicating failure is returned.
This API and hi_mpi_aenc_release_stream must appear in pairs. Call this API to obtain a stream. After the stream is used, call hi_mpi_aenc_release_stream to release the stream in time.
