  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.

  • Streaming RTP packets using SDP to ffmpeg

    4 avril 2017, par Johnathan Kanarek

    I have RTP packets in node.js server and I want to forward them to ffmpeg.
    I generate SDP files in the node.js server side and execute ffmpeg with the SDP as input.

    SDP :

    Command :

    ffmpeg -max_delay 5000 -reorder_queue_size 16384 -protocol_whitelist file,crypto,udp,rtp -re -i input.sdp -vcodec copy -acodec aac -y output.mp4

    Same with RTMP

    ffmpeg -max_delay 5000 -reorder_queue_size 16384 -protocol_whitelist file,crypto,udp,rtp -re -i input.sdp -vcodec copy -acodec aac -f flv rtmp://127.0.0.1:1935/live/myStream

    I get weird video that plays some vidoe, then get stuck, then plays some audio, back to video and so on, it never plays both video and audio together.

    BTW, when I created separate SDP files for the video and the audio and stream them as two inputs into the same output, I get valid stream but the audio is not in sync (about a second offset).

    ffmpeg -max_delay 5000 -reorder_queue_size 16384 -protocol_whitelist file,crypto,udp,rtp -re -i video.0.sdp -max_delay 5000 -reorder_queue_size 16384 -protocol_whitelist file,crypto,udp,rtp -re -i audio.1.sdp -vcodec copy -acodec aac -shortest -y output.mp4

    What is wrong with my SDP ?

    I tried changing analyzeduration, probesize, rtbufsize, vsync, framerate,
    I even tried to remap the streams using -map 0:v -map 0:a,
    nothing helped

    I also tried to use RTSP server, see log :

  • How to write unit tests for your plugin – Introducing the Piwik Platform

    17 novembre 2014, par Thomas Steur — Development

    This is the next post of our blog series where we introduce the capabilities of the Piwik platform (our previous post was How to verify user permissions). This time you’ll learn how to write unit tests in Piwik. For this tutorial you will need to have basic knowledge of PHP, PHPUnit and the Piwik platform.

    When is a test a unit test ?

    There are many different opinions on this and it can be sometimes hard to decide. At Piwik we consider a test as a unit test if only a single method or class is being tested and if a test does not have a dependency to the filesystem, web, config, database or to any other plugin.

    If a test is slow it can be an indicator that it is not a unit test. “Slow” is of course a bit vague. We will cover how to write other type of tests, such as integration tests, in one of our next blog posts.

    Getting started

    In this post, we assume that you have already installed Piwik 2.9.0 or later via git, set up your development environment and created a plugin. If not, visit the Piwik Developer Zone where you’ll find the tutorial Setting up Piwik and other Guides that help you to develop a plugin.

    Let’s create a unit test

    We start by using the Piwik Console to create a new unit test :

    ./console generate:test --testtype unit

    The command will ask you to enter the name of the plugin the created test should belong to. I will use the plugin name “Insights”. Next it will ask you for the name of the test. Here you usually enter the name of the class you want to test. I will use “Widgets” in this example. There should now be a file plugins/Insights/tests/Unit/WidgetsTest.php which contains already an example to get you started easily :

    1. /**
      2. 

    2.  * @group Insights
      3. 

    3.  * @group WidgetsTest
      4. 

    4.  * @group Plugins
      5. 

    5.  */
      6. 

    6. class WidgetsTest extends \PHPUnit_Framework_TestCase
      7. 

    7. {
      8. 

    8.  
      9. 

    9.     public function testSimpleAddition()
      10. 

    10.     {
      11. 

    11.         $this-&gt;assertEquals(2, 1+1);
      12. 

    12.     }
      13. 

    13.  
      14. 

    14. }
      15. 

    Télécharger

    We don’t want to cover how you should write your unit test. This is totally up to you. If you have no experience in writing unit tests yet, we recommend to read articles on the topic, or a book, or to watch videos or anything else that will help you learn best.

    Running a test

    To run a test we will use the command tests:run which allows you to execute a test suite, a specific file or a group of tests.

    To verify whether the created test works we will run it as follows :

    ./console tests:run WidgetsTest

    This will run all tests having the group WidgetsTest. As other tests can use the same group you might want to pass the path to your test file instead :

    ./console tests:run plugins/Insights/tests/Unit/Widgets.php

    If you want to run all tests within your plugin pass the name of your plugin as an argument :

    ./console tests:run insights

    Of course you can also define multiple arguments :

    ./console tests:run insights WidgetsTest

    This will execute all tests within the insights plugin having the group WidgetsTest. If you only want to run unit tests within your plugin you can do the following :

    ./console tests:run insights unit

    Advanced features

    Isn’t it easy to create a unit test ? We never even created a file ! You can accomplish even more if you want : You can generate other type of tests, you can run tests on Amazon’s AWS and more. Unfortunately, not everything is documented yet so we recommend to discover more features by executing the commands ./console list tests and ./console help tests:run.

    If you have any feedback regarding our APIs or our guides in the Developer Zone feel free to send it to us.
