hi_mpi_aenc_get_stream

The Atlas 200/300/500 Inference Product does not support this API.

The Atlas Training Series Product does not support this API.

Description

Obtains an encoded audio stream.

Restrictions

  • 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.

Prototype

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