Sets the alignment mode of the width and height of the JPEGD output image.

C Prototype

hi_u32 hi_mpi_vdec_set_jpegd_precision_mode(hi_vdec_chn chn, const hi_jpegd_precision_mode mode)

Python Function

ret = acl.himpi.vdec_set_jpegd_precision_mode(chn, mode)

Parameter	Description
chn	Int, decoding channel ID.
mode	int, width and height alignment mode of the JPEGD output image. For details, see hi_jpegd_precision_mode.

Return Value	Description
ret	Int, error code. 0: success. Other values: failure. For details, see VDEC/JPEGD Return Codes.

Before calling this API to set the alignment mode, ensure that a channel is created. Otherwise, the system returns the error code HI_ERR_VDEC_UNEXIST, indicating that no channel is created.
This API is valid only for JPEGD channels. For other channels, the system returns an error code indicating that the operation is not supported.
If this API is called before acl.himpi.vdec_start_recv_stream to set the alignment mode, or called after acl.himpi.vdec_start_recv_stream, the system returns an error code indicating that the operation is not allowed.
