Obtains the advanced RC parameters of an encoding channel.

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. Atlas inference products: The value range of the encoding channel ID is [0, 256). The JPEGE and VENC functions share the same channels, and the maximum number of channels is 256. Atlas 200I/500 A2 inference products: The value range of the encoding channel ID is [0, 128). The JPEGE and VENC functions share the same channels, and the maximum number of channels is 128.
mode	Int, mode of the bit rate controller of an encoding channel. For details, see hi_venc_rc_mode.

Return Value	Description
rc_param	Dict, advanced parameter dictionary of the encoding channel bit rate controller. For details, see hi_venc_rc_param.
ret	Int, error code. 0: success. Other values: failures. For details, see VENC/JPEGE Return Codes.

Return Value

Description

rc_param

Dict, advanced parameter dictionary of the encoding channel bit rate controller. For details, see hi_venc_rc_param.

ret

Int, error code.

Call this API after an encoding channel is created and before the channel is destroyed.
