Hey All,
I am using C++ to communicate with google speech api server.
I am using the usual approach of setting a deadline for the clientcontext
to handle timeout functionality.
I have put the *deadlines *like:
void SetContextDeadline(grpc::ClientContext *context, unsigned int
user_defined_deadline){
context->set_deadline(std::chrono::system_clock::now() +
std::chrono::seconds(user_defined_deadline));
}
Now, this function is called whenever I want to set the deadline *from
now(time)*
*int main(){*
auto creds = grpc::GoogleDefaultCredentials();
auto channel = grpc::CreateChannel("speech.googleapis.com", creds);
std::unique_ptr<Speech::Stub> speech(Speech::NewStub(channel));
grpc::ClientContext context;
// Set timeout of 8 seconds => also this is the timeout which I am not able
to cancel to set new timer
// Whenever it ends (after 8 seconds) my program is terminated
SetContextDeadline(&context,8);
auto streamer = speech->StreamingRecognize(&context);
// The microphone thread writes the audio content.
std::thread microphone_thread(&MicrophoneThreadMain, streamer.get(),
file_path);
// Read responses.
StreamingRecognizeResponse response;
while (streamer->Read(&response)) { // Returns false when no more to
read.
// Now I want to cancel the previous deadline to set this new deadline,
everytime I enter this loop
// I am seeing that this is setting the new deadline but the program
still terminates at the older timeout
SetContextDeadline(&context,8);
// Dump the transcript of all the results.
// Implementation of response display
}
}
Thanks in advance for your help
