hi_s32 hi_mpi_venc_get_ref_param(hi_venc_chn chn, const hi_venc_ref_param *ref_param)

Python Function

ref_param, ret = acl.himpi.venc_get_ref_param(chn)

Parameters

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

Return Value	Description
ref_param	Dict, dictionary of advanced frame skipping reference parameters for an H.264/H.265 encoding channel. For details, see hi_venc_ref_param.
ret	Int, error code. 0 indicates success. Other values indicate failure. For details, see VENC/JPEGE Return Codes.
