Obtains the tendency configuration of the CU/MB mode of a channel.

C Prototype

hi_s32 hi_mpi_venc_get_cu_pred(hi_venc_chn chn, hi_venc_cu_prediction *cu_pred)

Python Function

cu_pred, ret = acl.himpi.venc_get_cu_pred(chn)

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.

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.

Return Value	Description
cu_pred	Dict, dictionary of the tendency to use the CU mode. For details, see hi_venc_cu_prediction.
ret	Int, error code. 0: success. Other values: failures. For details, see VENC/JPEGE Return Codes.

Return Value

Description

cu_pred

Dict, dictionary of the tendency to use the CU mode. For details, see hi_venc_cu_prediction.

ret

Int, error code.

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