hi_s32 hi_mpi_venc_get_jpeg_huffman_param(hi_venc_chn chn, hi_venc_jpeg_huffman_param *jpeg_huffman_data)

Python Function

jpeg_huffman_data, ret = acl.himpi.venc_get_jpeg_huffman_param(chn)

Parameters

Parameter	Description
chn	Int, encoding channel ID.

Return Value

Return Value	Description
jpeg_huffman_data	Dict, dictionary of advanced Huffman parameters. For details, see hi_venc_jpeg_huffman_param.
ret	Int, error code. 0 indicates success. Other values indicate failure. For details, see VENC/JPEGE Return Codes.

Description

jpeg_huffman_data

Dict, dictionary of advanced Huffman parameters. For details, see hi_venc_jpeg_huffman_param.

ret

Int, error code.

0 indicates success.
Other values indicate failure. For details, see VENC/JPEGE Return Codes.

Restrictions

This API must be called after an encoding channel is created and before the channel is destroyed.

If acl.himpi.venc_set_jpeg_huffman_param has not been called to set the advanced Huffman coding parameters, the default Huffman coding parameters are returned.
