• Power-Up your Piwik installation with Custom Reports

  13 novembre 2017, par InnoCraft — Plugins

  Would you like to create a report in Piwik with just the data you want and nothing else ? Would you like to be free to decide the shape of it ? Are you struggling with the Piwik database and wish you could have an easy interface to create the report you want ? Are you tired of exporting your data in a spreadsheet ? Since last October, there’s a solution and it’s called Custom Reports.

  With custom reports you will :

  1. get a user-friendly interface to create the report you wish
  2. see all the possible combinations to create the report you desire
  3. reveal new data combinations which were not directly available in Piwik

  User friendly interface

  The time when you created your reports from MySQL database is over. Now with custom reports you can create the report you want and get the data you need in just a few seconds.
  Custom reports are part of the main user interface. You can access them in just one click :

  

  As you can see from above the interface is straightforward, just indicate the name of your report and start to select the dimensions and metrics you would like to see.

  See all the possible combinations to create the report you desire

  As a user the big question has always been, how much data does Piwik collect and where can I find a list of all those data points ? Here you have the solution. Piwik is gathering in custom reports all the possible combinations so you can select only the data you want :

  

  Creating such a report is going to take you no more than a minute. As with any reports within Piwik, you can easily get information regarding the specific data you are using by hovering your mouse on the question mark next to each dimension and metric :

  

  Make new combinations which were not directly available in Piwik

  By default, not all combinations are possible within the Piwik user interface. Now thanks to Custom Reports, you can easily design the report you want. Here is for example a report crossing page titles and page url :

  

  You can then identify if there are any duplicate titles within your content and see the associated URL in a single report.

  You could also identify easily what are your most viewed entry page from Google :

  

  Custom reports can also be used with segments and filters in order to get even more specific data.
  Here we have an example of a custom report designed to take into consideration only the visits coming from Wikipedia :

  

  What is the next step ?

  As you understood it, Piwik custom reports is the must-have plugin in order to take your Piwik to the next level. Why wait ? Piwik custom reports are available through the marketplace.

  If you are not sure yet, you can always give it a try within our Piwik Cloud infrastructure.

• FFmpeg Stream RTSP input and save to file at the same time using nodejs

  26 juin 2015, par Ofir Attia

  I am using node-rtsp-stream module to stream RTSP to web with nodejs.
  I am streaming RTSP source with ffmpeg, for example RTSP SOURCE - EXAMPLE

  I know that I can save one or many inputs to many outputs but I dont know if there is option to stream the input and save it to file at the same time without executing two process of ffmpeg.
  With the following example I am able to stream the RTSP source
  

  ffmpeg -i rtsp-url -rtsp_transport tcp -f  mpeg1video -b:v 800k -r 30  

  On the module is look like that :
  

  this.stream = child_process.spawn("ffmpeg", [ "-i", this.url, "-rtsp_transport", "tcp",'-f', 'mpeg1video', '-b:v', '800k', '-r', '30', '-'], {
  
        detached: false
  
      });
  
      ff =child_process.spawn("ffmpeg", [ "-i", this.url,  '-b:v', '800k', '-r', '30', '1.mp4'], {
  
        detached: false
  
      });
  
      this.inputStreamStarted = true;
  
      this.stream.stdout.on('data', function(data) {
  
        return self.emit('mpeg1data', data);
  
      });
  
      this.stream.stderr.on('data', function(data) {
  
        return self.emit('ffmpegError', data);
  
      });

  As you can see I am using two process of ffmpeg to do what I want but
  If anyone faced with this issue and solve it with one command ( process ), I would like to get some suggestions.
  How to stream RTSP source and save it to file at the same time.

• Save and re-stream RSTP video as straight UDP

  30 septembre 2013, par user1701362

  I am trying to write a program that will connect to a RTSP video source and redirect the video data to another location using UDP. I am also saving the RTSP packets to be able to replay the video stream at a latter moment in time as well. Right now my program can connect to the RTSP video stream and redirect and save, but when I try to look at the redirected video I get nothing using VLC.

  Currently the program just strips out the datagram from the RTSP video packets it receives in its open UDP socket and re-sends them using this code using the boost asio library.

  newVideoSocket->send_to(&dg.data[0], dg.data.size() ,Endpoint);

  When I look at the traffic using Wireshark I see that it is actually sending the data to the new address and it is recognized as a UDP packet, but when I try and view the video using VLC nothing happens. The video stream is Mpeg4 with the video encoded as H.264 and VLC can play it.

  I have tried to connect to the redirected stream as UDP and as RTP at both multicast and unicast addresses but have had no success. Do I need to add or take something out of the datagram before I resend it ? Or is it something wrong with how I am tring to view it in VLC ? Thanks for the help.
