I am trying build an C++ application, which will try to connect Shoutcast/Icecast server, get an audio file, then stream the audio file into audio device. There is winamp application in windows, which already does the same. But I would like the same kind of application in C++. I have read the http://www.smackfu.com/stuff/programming/shoutcast.html link. But not sure how I should start. I would need specific help on this: a) How do I connect to shotcast server? b) get the audio file url? c) How should I start streaming? I have built one socket program which can connect to server, can send/recv binary data. Hope this can help here. But I am unable to start on above three points? I have read stackoverflow urls on this:
Stream getUserMedia to an Icecast server?
Audio streaming using C++ tutorial and sample code
http://forums.radiotoolbox.com/viewtopic.php?t=74
But could not help much.
Can you please help me on this?
SHOUTcast/Icecast are essentially HTTP. You should be searching on how to make an HTTP request.
There is a small difference for SHOUTcast servers though... the status line they return is non-standard:
ICY 200 OK
A normal status line would be:
HTTP/1.1 200 OK
Once you learn how to make an HTTP request, you will be streaming. Later on if you want to get the metadata, you can follow the SmackFu link you posted.

I don’t know if I can say “I’m sorry for ask” but I spent more than a week looking for a solution without success. I have a Jetson Nano and with OpenCV I get and process an image at 4fps, I need to send this video to a web server to allow the client connected to the server get the video. Everything need to be written in C++.
Because a need a low latency I did test with GStreamer and WebRTC without success. I don’t have any web server ready, so I can use any implementation.
Anyone know where I can find some example implementation with this schema?
You can use mediasoup to send data to the server to then send the stream with rtp to another endpoint like gstreamer or ffmpeg.
Here is a recording project where data is sent from the browser -> server -> gstreamer -> file.
Mediasoup is written in c++ and has a wrapper for js.
I had similar problem and used such example from GStreamer WebRTC official repo. It's written in Python for Janus Gateway video rooms but I think it can be easily rewritten in C++ as you need.
In the code for OpenCV, I used V4L2Loopback as a virtual output device to be used as input for GStreamer WebRTC example.
I hope such approach may help you.
I think no need to send it to a Web Server. In Gstreamer examples [https://github.com/GStreamer/gst-examples]. The SendOnly example sends a video to a Web Client Using WebRTC. You can modify it to send an OpenCV mat.
I am trying to build a Virtual Assistant in UE4. I need to somehow send my response from DialogFlow to UE4 for use in the Oculus Lipsync Plugin.
Basically, I have 3 media options for the response:
-16-Bit Linear PCM
-mp3
-Ogg Opus
I have a TCP Server and Client connection set up between a Python Script and UE4, so I can send data to and from easily.
I have my sequencing correct so one script waits for the full Byte Array to be sent via the socket etc.
Basically, I want to send the responses to each Query the user sends to DialogFlow INTO UE4 Via my TCP Socket, and be able to play and access that Audio within UE4.
I need to somehow stream the response from DialogFlow into UE4 as it gives me the responses.
Is what I'm trying to do even possible? I'm just trying to stream in Audio for use within UE4 and I am really struggling to get it working. Very annoying as this is the last piece of the puzzle I need to finish....
Please let me know if you have any advice or help you can offer!
I would like to make of some sort of a streaming server. I would like it to receive RTSP streams over the net from live streams (e.g. webcam, ipcam, etc.) then broadcast that same stream on my local network using a different URL. I know gstreamer can do it quite well but I don't know how. I'm quite confused with the way the documentation is written. Can somebody help me?
If you would like to retransmit the video streams using RTSP as well, you can use GStreamer RTSP Server. There is a lot of examples on the Internet how to use it. The best source of the examples is the gst-rtsp-server's examples directory:
http://cgit.freedesktop.org/gstreamer/gst-rtsp-server/tree/examples
As you want to retransmit existing RTSP streams, you'll need to use the rtspsrc element for reception of the remote streams.
I think you are looking for something like this: https://github.com/jayridge/rtsprelay. It configures one rtsp server to receive clients on two urls with a record link and a play link.
This example uses a dynamic form:
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1454
rtsp://server/path?uri=encoded-URI
you HTML encode the destination in URI form and add a path where it should register this camera to. The first time you connect; it will take some time, after that; the sessions are re-used.
I have a c++ project (server-side) which sends the data to the client side with the help of event source. Now for debugging purposes I have maintained a trace file (text). On all the critical areas in the c++ code where there is a fear of code-break, I have added a line which writes the "success" text to this trace file. It works fine. I can know where the code is success and where it failed.
But I am on the server side. I want to avail this facility to the client too. However, I am unsure about how to do that? Should I stream the file on web-browser, or is there any other way I can send the data "live" to web-browser?
I checked this link, however, I am not sure if I can use this. http://www.tutorialspoint.com/cplusplus/cpp_web_programming.htm
Thanks
your question is a bit confusing, and without any sample of your code it is a bit unclear of what you want to do. however, the best suggestion i can give is to do this:
Store the text document on a server of your choice.
write a program to contact the server and download the data. (Using Winsock.h)
OR
Directly send the file to the computer. you'll have to write a program to contact the server at which point B is located.
for information on writing an application using Winsock.h, check here:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms737629(v=vs.85).aspx
if you really must store the data live in a web browser, then take a look at Java or VisualBasic, as both are heavily supported in all web browsers, while C++ is not.
Let me see if I understand you correctly. You want to send success / failure of the webserver to your client program?
Well, that's part of the job of a webserver, as dictated by the http protocol. A webserver will respond to a client request with a response header, followed by the requested page (if it exists as a valid resource on the server).
For more information on http response headers have a look at this article, or this wikipedia page, which both detail the request / response conversation between browser and webserver.
Hope this helps.
I am implementing a client/server application where video streaming occurs between two computers (in one direction). I would like to have the server publish an SDP file when it starts streaming. The client would then be able to download this SDP file and use it to get the stream. In order to implement this it seems I need to include a RTSP server in my server application.
I am planning to use either libVLC or GStreamer for the client. Both are able to get incoming video streams using the info from an SDP file.
Server-side I don't really know where to start. Can anyone recommend a good C++ library that would allow me to create a small RTSP server?
Use Live555 LGPL library or for fun, read the RFC and implement :-)
Libcurl's library offers a simple example that can be usefull for the server side..
Take a look at: https://curl.haxx.se/libcurl/c/rtsp.html
