streaming

问题 What would be the most elegant way to receive data from a streaming JSON API using AFNetworking? AFNetworking provides excellent support for receiving non-streaming data from JSON APIs, but I couldn't find any examples of streaming JSON. 回答1: AFNetworking does not have a built-in streaming SAX-style JSON operation, but it should be straight forward to create your own. Create a subclass of AFJSONRequestOperation Use the outputStream property of the operation during initialization to hook it up

问题 I'm running a streaming job in Hadoop (on Amazon's EMR) with the mapper and reducer written in Python. I want to know about the speed gains I would experience if I implement the same mapper and reducer in Java (or use Pig). In particular, I'm looking for people's experiences on migrating from streaming to custom jar deployments and/or Pig and also documents containing benchmark comparisons of these options. I found this question, but the answers are not specific enough for me. I'm not looking

问题 I HAD this situation: Clicking on a html submit button, I call views.stream_response which "activates" views.stream_response_generator which "activates" stream.py and return a StreamingHttpResponse and I see a progressive number every second up to m at /stream_response/ : 1 2 3 4 5 6 7 8 //e.g. my default max value for m stream.py from django.template import Context, Template import time def streamx(m): lista = [] x=0 while len(lista) < m: x = x + 1 time.sleep(1) lista.append(x) yield "<div>

问题 I want to stream a part of screen using vlc library. I wrote a small example: #include <iostream> #include <cstdlib> #include <vlc/vlc.h> int main(int argc, char**argv) { libvlc_instance_t * inst = libvlc_new(argc, argv); libvlc_vlm_add_broadcast(inst, "mybroad", "screen://", "#transcode{vcodec=h264, venc=x264,vb=0,scale=0, acodec=mpga,ab=128,channels=2, samplerate=44100}:http{mux=ffmpeg{mux=flv}, dst=:7777/}", 0, NULL, 1, 0); libvlc_vlm_play_media(inst, "mybroad"); std::cout << "ready" <<

问题 My goal is to transmit *.wav file over LAN network without delay or with minimal one. Also we read a file on a server machine by parts, 320 bytes both. After this we send packets by UDP and write receiving in jitter-buffer. The size of the jitter-buffer is 10. What delays should I set on timers for clear sound? Here is the sender: void MainWindow::on_start_tx_triggered() { timer1 = new QTimer (this); udpSocketout = new QUdpSocket(this); qDebug()<<"Start"; for (int i = 0; i < playlist.size();

问题 I am currently looking to develop an application that utilises Dash through the ExoPlayer in Android. To begin with I am going through the demo project however am having trouble with even creating a simple working instance of ExoPlayer that can stream mp3 or similar. Would really appreciate any help anyone can give relating to getting a very simple exoplayer instance working from which i can adapt and build upon or if anyone has any leads for more references or guides which I can follow as

问题 This code streams large files to our users: // Open the file. iStream = new System.IO.FileStream(filepath, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.Read); // Total bytes to read: dataToRead = iStream.Length; // Read the bytes. while (dataToRead > 0) { // Verify that the client is connected. if (Response.IsClientConnected) { // Read the data in buffer. length = iStream.Read(buffer, 0, 10000); // Write the data to the current output stream. Response.OutputStream

问题 I've figured out how I can get audio playing in the background on ios4, however I've noticed that some apps also replace the iPod dock icon with their own app icon. (Last.fm & Spotify for example). They are also able to use the dock media controls to pause and resume their streams. Does anyone know how to do this? Thanks 回答1: It's easy you have to respond to the Remote Control Events. This also lets you control your app with the headset. In lets say viewDidLoad call: [[UIApplication

问题 Just recently I started to investigate a tricky problem with WCF streaming in which a CommunicationException is produced if the client waits for any longer than 130 seconds in between sends to the server. Here is the full exception: System.ServiceModel.CommunicationException was unhandled by user code HResult=-2146233087 Message=The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying
