Obtains the slice split attributes of a channel.

C Prototype

hi_s32 hi_mpi_venc_get_slice_split(hi_venc_chn chn, hi_venc_slice_split *slice_split)

Python Function

slice_split, ret = acl.himpi.venc_get_slice_split(chn)

Parameter	Description
chn	Int, encoding channel ID. For the Atlas inference product, the value range of the encoding channel ID is [0, 256). The JPEGE and VENC functions share channels. The maximum number of channels is 256. For the Atlas 200I/500 A2 inference product, the value range of the encoding channel ID is [0, 128). The JPEGE and VENC functions share channels. The maximum number of channels is 128.

Parameter

Description

chn

Int, encoding channel ID.

For the Atlas inference product, the value range of the encoding channel ID is [0, 256). The JPEGE and VENC functions share channels. The maximum number of channels is 256.
For the Atlas 200I/500 A2 inference product, the value range of the encoding channel ID is [0, 128). The JPEGE and VENC functions share channels. The maximum number of channels is 128.

Return Value	Description
slice_split	Dict, stream slice split parameter for H.264/H.265 encoding.
ret	Int, error code. 0 indicates success. Other values indicate failure. For details, see VENC/JPEGE Return Codes.

Description

slice_split

Dict, stream slice split parameter for H.264/H.265 encoding.

ret

Int, error code.

Only H.264/H.265 encoding channels support this API.
This API must be called after an encoding channel is created and before the channel is destroyed.
