Description

Sets the advanced RC parameters of an encoding channel. If this API is not called, the default advanced RC settings will be used.

Call this API after an encoding channel is created and before the channel is destroyed. Before this API call, you are advised to obtain the advanced RC parameters of the encoding channel by calling hi_mpi_venc_get_rc_param.

Prototype

hi_s32 hi_mpi_venc_set_rc_param (hi_venc_chn chn, const hi_venc_rc_param *rc_param)

Parameters

Parameter	Input/Output	Description
chn	Input	Encoding channel ID. 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. 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.
rc_param	Input	Pointer to the advanced RC parameters of an encoding channel.
