acl.himpi.vdec_set_jpegd_precision_mode

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)

Function Usage

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

The Atlas 200/300/500 Inference Product does not support this API in the current version.

The Atlas Training Series Product does not support this API in the current version.

Input Description
chn: int, decoding channel ID.

mode: int. Sets the alignment mode of the width and height of the decoded JPEGD output image. For details, see hi_jpegd_precision_mode.

Return Value

ret: int, error code.

Restrictions
  • 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.
  • This API should be called before acl.himpi.vdec_start_recv_stream. Otherwise, the system returns an error code indicating that the operation is not allowed.
