C Prototype

hi_s32 hi_mpi_venc_get_rc_param(hi_venc_chn chn, hi_venc_rc_param *rc_param)

Python Function

rc_param, ret = acl.himpi.venc_get_rc_param(chn, mode)

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.
mode	int, bit rate controller mode of an encoding channel. For details, see hi_venc_rc_mode.

Return Value	Description
rc_param	Dict, dictionary of advanced RC parameters of an encoding channel. For details, see hi_venc_rc_param.
ret	Int, error code. 0 indicates success. Other values indicate failure. For details, see VENC/JPEGE Return Codes.

Description

rc_param

Dict, dictionary of advanced RC parameters of an encoding channel. For details, see hi_venc_rc_param.

ret

Int, error code.

This API must be called after an encoding channel is created and before the channel is destroyed.
