Frees the stream buffer.

C Prototype

        
             hi_s32 hi_mpi_venc_release_stream(hi_venc_chn chn, hi_venc_stream *stream);

Python Function

        
             ret = acl.himpi.venc_release_stream(chn, stream)

Parameter	Description
chn	Int, decoding channel ID.
stream	Dict, stream dictionary. If stream is left empty, the error code HI_ERR_VENC_NULL_PTR is returned.

Return Value	Description
ret	Int, error code. 0 indicates success. Other values indicate failure. For details, see VENC/JPEGE Return Codes.

Ensure that a channel has been created. Otherwise, the error code HI_ERR_VENC_UNEXIST is returned.
Use this API in pair with acl.himpi.venc_get_stream. Free the stream buffer in a timely manner to avoid encoding suspension due to stream buffer insufficiency. In addition, you must comply with the principle of "first obtained, first released".
When an encoding channel is reset, the stream buffer becomes invalid, even if the packets are not released.
An attempt to free the buffer of an invalid stream returns the HI_ERR_VENC_ILLEGAL_PARAM error.

For details about the API call sequence, see JPEGE and VENC.
