Recording Studio ‐ WebSockets - ddpalacios/home-server GitHub Wiki

In order to record audio, the audio bytes must be sent to the server. Long polling can be efficient but it could lead to overhead. Websockets provides a consistent connection, avoids repetitive HTTP handshakes, Reduces latency and bandwidth usage, and is ideal for high-frequency, interactive use cases (e.g. chat, gaming, IoT)

Tasks:

  • Create Websocket.h/c files
  • initialize websocket protocol by generating accept key
  • determine if buffer is websocket frame
  • decode websocket buffer
  • dynamically store data into array

psuedocode

     buf = SSL_read( ... )


  if ( GET )

     if ( route == '/start_websocket') {
             int success = initialize_websocket_connection( ... )

            if (! success ) {

               SSL_Write ("Could not establish websocket connection" ) 

              }

     }

   if (route == '/stop_websocket') {
       int success = close_websocket_connection(); 
       if (!success) {

        SSL_Write ("ERROR has occured closing connection" ) 

    }
  }

  if  (is_websocket_buffer (buffer) ) {
     
       char* websocket_message = read_websocket_buffer(buf);

       collect_message(websocket_message)
