• mediastreamsegmenter stops sending id3 metadata using HLS

  9 mai 2013, par alawson421

  I am using a combination of ffmpegand Apple's mediastreamsegmenter and id3taggenerator to create a HLS stream with metadata (ID3) embedded in it. I have all of the applications running and am able to retrieve the metadata out of the stream on the client side, but the issue is that after what seems like a random amount of time, the client stops receiving metadata on the stream.

  Here is what I have working now :

  This is the ffmpeg and mediastreamsegmenter part :

  ffmpeg -i udp://@:5010 -c:v libx264 -crf:v 22 -b:v 500k -preset:v veryfast -c:a libfdk_aac -b:a 64k -f mpegts - | mediastreamsegmenter -b http://localhost/stream -f /usr/local/nginx/html/stream/ -t 10 -s 4 -S 1 -D -y id3 -m -M 4242 -l log.txt

  This is taking a udp stream on the localhost on port 5010 and encoding the video and audio to H.264 and AAC, respectively. It is pipping the MPEG-2 transport stream segments to the mediastreamsegmenter, which in turn is generating the .M3U8 file and associated .ts files and placing them on a NGINX webserver. The mediastreamsegmenter is also listening on port 4242 for tcp traffic from the id3taggenerator which I will show how I am using it now :

  id3taggenerator -text '{"x":"12","y":"36"}' -a localhost:4242

  As you can see, I am sending some simple x-y coordinates in JSON as text to the mediastreamsegmenter listening on port 4242. I am actually using a Python script to send some test data at the moment. Here is the script :

  #!/usr/local/bin/python3
  
  from subprocess import call
  
  from time import sleep
  
  
  
  for i in range(0, 10):
  
      for j in range(0, 10):
  
          x = str(20 * i)
  
          y = str(20 * j)
  
          print("X: " + x + " - Y: " + y)
  
          call(["id3taggenerator", "-text", "{\"x\":\"" + x + "\",\"y\":\"" + y + "\"}", "-a", "localhost:4242"])
  
          sleep(1.0)

  This script is just sending a bunch of x-y coordinates using the id3taggenerator CLI. I have adjusted the sleep amount from 0.1 to 15 and it doesn't seem to make any difference. The client application that is getting the metadata out of the stream only prints out anywhere from 4 to 35 points, but never has it ever received all of the x-y coordinates.

  I am wondering if there is a limit to the amount of metadata that can sent per frame, but I cannot seem to find anything that specifies a hard-limit value for any of these tools...

• 9 plugins you should definitely have heard of to prevent data leaks, security breaches and to get more flexibility in the way you log in to your Piwik.

  At Piwik and at InnoCraft, we have always focussed on Security and take it very seriously. We were one of the first open source projects to offer a bug bounty for reporting security issues responsibly, Piwik has gone through several security audits and all changes in Piwik go through security reviews by our security experts.

  On the Piwik Marketplace you will find some plugins that give you just that extra bit of additional security to keep your data even more secure and to let you secure how your users log in to your Piwik.

  Security Info

  This plugin provides security information about the server(s) your Piwik is running on and offers suggestions on how to improve the security settings of your servers. We highly recommend to install the Security Info plugin. Checks performed include for example usage of the latest PHP version, usage of latest Piwik version, usage of PHP ini settings like magic_quotes_gpc and more. More details & download

  Google Authenticator

  This plugins adds Two Factor Authentication, also known as 2FA, to Piwik. When logging in to Piwik, it forces you to confirm the identity by utilizing a combination of two different components. This means if someone knows your password, they will still need the other component in order to successfully log in, in this case a code that changes every minute on your phone.

  Activity Log

  The plugin gives you a detailed audit log of all activities that happen in your Piwik for better security and problem diagnostic. It provides documentary evidence of over 80 different activities that happen in your Piwik and lets you for example see when someone successfully logged in, when someone tried to log in with your username, when someone deleted data, and much more.

  Performance Info

  This plugin checks your Piwik configuration and compares it with some best practice settings. For example whether debug modes are disabled in a production environment, whether the example plugins that are shipped with Piwik are disabled, and more. Please note that this plugin works only with Piwik 2. More details & download

  Login Ldap

  Some companies might already manage their users in an LDAP server. This plugin allows you to log in to your Piwik via a central LDAP and supports web server authentication (eg. for Kerberos SSO). It authenticates with an LDAP server and uses LDAP information to personalize Piwik. More details & download

  Login Shibboleth

  Shibboleth is an open-source project that provides a Single Sign-On and allows websites to make informed authorization decisions in a privacy-preserving manner. Using this plugin allows you to connect to an existing Shibboleth environment so you need to manage users only once. More details & download

  Login Http Auth

  This plugin allows you to sign in to your Piwik using the HTTP Auth protocol instead of the standard login mechanism. It extends the standard Piwik authentication to use Basic HTTP Authentication. This may be useful if you use Basic HTTP Authentication already anyway and don’t want to manage your users additionally in Piwik itself. We recommend to use this only over SSL, for example with the Force SSL plugin. More details & download

  Custom Development

  Piwik is an analytics platform that you can extend and customize to your needs. Besides many configuration options you can change existing functionality and also build new functionality on top of Piwik, for example to log in to your Piwik via any Single-Sign-On. Read more about extending Piwik on the Piwik Developer Zone or get in touch with us and we take care of it for you.

  MAINTAINERS : Split project server admin list
  This updates the list closer to reality.
  
  Iam not a professional server admin, iam happy to help maintain the box as i have
  
  done in the past. But iam not qualified nor volunteering to fix sudden problems
  
  nor do i do major upgrades (i lack the experience to recover the box remotely if
  
  something goes wrong) and also iam not maintaining backups ATM (our backup system
  
  had a RAID-5 failure, raz is working on setting a new one up)
  Maybe this should be signaled in a different way than spliting the lines but ATM
  
  people ping me if something is wrong and what i do is mainly mail/ping raz
  
  and try to find another root admin so raz is not the only active & professional
  
  admin on the team. It would be more efficient if people contact raz and others
  
  directly instead of depending on my waking up and forwarding a "ffmpeg.org" is down note
