hi_mpi_venc_get_roi_attr

The Atlas 200/300/500 Inference Product does not support this API.

The Atlas Training Series Product does not support this API.

Obtains the ROI attributes of an H.264/H.265 channel. For details about the ROI encoding function, see ROI Encoding Function.

This API is used to obtain the configuration of an ROI with a specified index in an H.264/H.265 encoding channel.

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

It is recommended that this API be called after an encoding channel is created and before encoding is started, to reduce the number of the API calls during encoding.

Parameter	Input/Output	Description
chn	Input	Encoding channel ID.
idx	Input	Index of the ROI for an H.264/H.265 encoding channel.
