Function Usage

Obtains the protobuf result of the output element on the stream and send it to appsink. appsink obtains the data in the queue in blocking mode. If the queue is empty, the data is blocked. Multi-thread concurrency is not supported.

This API must be used together with SendProtobuf. Otherwise, data stacking may occur.

Prototype

std::vector<MxstProtobufOut> MxStreamManager::GetProtobuf(const std::string& streamName, int outPluginId, const std::vector<std::string>& keyVec);

Parameters

Parameter	Input/Output	Description
streamName	Input	Stream name.
outPluginId	Input	ID of the object output plugin, that is, the ID of the appsrc element
keyVec	Input	Key of the protobuf to be obtained. The corresponding protobuf result is obtained based on the key. The memory is managed by the smart pointer and does not need to be released.

Response Parameters

Data Structure	Description
std::vector<MxstProtobufOut>	For details about the output data list of the inference service, see MxstProtobufOut.
