Sets the advanced RC parameters of an encoding channel.

C Prototype

hi_s32 hi_mpi_venc_set_rc_param(hi_venc_chn chn, const hi_venc_rc_param *rc_param);

Python Function

ret = acl.himpi.venc_set_rc_param(chn, rc_param)

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

Return Value	Description
ret	Int, error code. 0: success. Other values: failures. For details, see VENC/JPEGE Return Codes.

This API must be called after an encoding channel is created and before the channel is destroyed.
If this API is not called to set the advanced RC parameters of an encoding channel, the default advanced RC settings will be used.
As a best practice, you can first obtain the current advanced RC settings of the target channel by using acl.himpi.venc_get_rc_param and pass the updated settings to this API call.
