Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

Streaming Video from RTMP to EMGUCV
22 juillet 2017, par IsuruI’m trying to stream a webcam using RTMP to an EMGUCV project in order to process the video. I have set up a private RTMP server in a linux box using this tutorial,
https://obsproject.com/forum/resources/how-to-set-up-your-own-private-rtmp-server-using-nginx.50/I’m testing the webcam stream using ffmpeg with the following commands,
-
Write to the rtmp server using,
ffmpeg -y -f vfwcap -framerate 25 -video_size 640x480 -i 0 -an -f flv rtmp://rtmp-server:1935/live/stream
-
Read from the rtmp server using,
ffplay -fflags nobuffer rtmp ://rtmp-server:1935/live/stream -loglevel verbose
I’m able to write a simple OpenCV C++ application to read the stream and display it. Code below,
cv::VideoCapture vcap;
cv::Mat image;
const std::string videoStreamAddress = "rtmp://rtmp-server:1935/live/stream";
if(!vcap.open(videoStreamAddress)) {
printf("Error opening video stream or file");
return -1;
}
cv::namedWindow("Output Window");
cv::Mat edges;
for(;;) {
if(!vcap.read(image)) {
printf("No frame");
cv::waitKey();
}
cv::imshow("Output Window", image);
if(cv::waitKey(1) >= 0) break;
}
return 0;The above code works properly. However when I try it using EMGUCV C#, I get the error message
unable to create to capture from rtmp://rtmp-server:1935/live/stream
This is my C# Code,
public partial class MainForm : Form
{
private static Capture _cameraCapture;
public MainForm()
{
InitializeComponent();
Run();
}
void Run()
{
try
{
_cameraCapture = new Capture("rtmp://192.168.56.101:1935/live/stream");
}
catch (Exception e)
{
MessageBox.Show(e.Message);
return;
}
}
}Do I need a specific build of EMGUCV with FFMPEG or is RTMP capturing not available in EMGUCV ?
