Parameter Description

Parameter

Description

chn

Int, decoding channel ID.

  • Atlas inference products: The value range of this parameter is [0, 256). The JPEGD and VDEC functions share the same channels, and the maximum number of channels is 256.
  • Atlas A2 training products/Atlas A2 inference products: The value range of this parameter is [0, 256). The JPEGD and VDEC functions share the same channels, and the maximum number of channels is 256. Among them, a maximum of 256 JPEGD decoding channels and 32 VDEC decoding channels are supported.
  • Atlas 200I/500 A2 inference products: The value range of this parameter is [0, 128). The JPEGD and VDEC functions share the same channels, and the maximum number of channels is 128.
  • Atlas A3 training products/Atlas A3 inference products: The value range of this parameter is [0, 256). The JPEGD and VDEC functions share the same channels, and the maximum number of channels is 256. Among them, a maximum of 256 JPEGD decoding channels and 32 VDEC decoding channels are supported.

Return Value Description

Return Value

Description

ret

ret: int, error code.

Restrictions

  • Ensure that a channel has been created. Otherwise, the error code HI_ERR_VDEC_UNEXIST is returned.
  • Ensure that the channel has stopped receiving streams. Otherwise, the error code HI_ERR_VDEC_NOT_PERM is returned.
