  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée

  • FFMPEG command on Android Jave Process does not fully execute

    8 novembre 2014, par user2491598

    The issue I am having is very strange. I have an FFMPEG executable binary library installed on my Android and I am trying to execute this command

    ffmpeg -loop 1 -i /storage/emulated/0/image.jpg -i /storage/emulated/0/input.mov -filter_complex '[0:v][1:v] overlay' -shortest /storage/emulated/0/output.mp4

    and my JAVA code looks like

    try {
    
            Runtime.getRuntime().exec("chmod 700 " + mFfmpegPath);
    
            cmd.add(mFfmpegPath);
    
            cmd.add("-loop");
    
            cmd.add("1");
    
            cmd.add("-i");
    
            cmd.add("/storage/emulated/0/image.jpg");
    
            cmd.add("-i");
    
            cmd.add("/storage/emulated/0/pizza.mov");

            p.waitFor();
    
            return run;

    For some reason I the execution does not fully finish and it stops. It does not even create an output file in my Android storage. Here is the log file from the process stream

  • How to make your plugin multilingual – Introducing the Piwik Platform

    29 octobre 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 Generating test data – Introducing the Piwik Platform). This time you’ll learn how to equip your plugin with translations. Users of your plugin will be very thankful that they can use and translate the plugin in their language !

    Getting started

    In this post, we assume that you have already 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.

    Managing translations

    Piwik is available in over 50 languages and comes with many translations. The core itself provides some basic translations for words like “Visitor” and “Help”. They are stored in the directory /lang. In addition, each plugin can provide its own translations for wordings that are used in this plugin. They are located in /plugins/*/lang. In those directories you’ll find one JSON file for each language. Each language file consists in turn of tokens that belong to a group.

    {
    
    "MyPlugin":{
    
        "BlogPost": "Blog post",
    
        "MyToken": "My translation",
    
        "InteractionRate": "Interaction Rate"
    
    }
    
}

    A group usually represents the name of a plugin, in this case “MyPlugin”. Within this group, all the tokens are listed on the left side and the related translations on the right side.

    Building a translation key

    As you will later see to actually translate a word or a sentence you’ll need to know the corresponding translation key. This key is built by combining a group and a token separated by an underscore. You can for instance use the key MyPlugin_BlogPost to get a translation of “Blog post”. Defining a new key is as easy as adding a new entry to the “MyPlugin” group.

    Providing default translations

    If a translation cannot be found then the English translation will be used as a default. Therefore, you should always provide a default translation in English for all keys in the file en.json (ie, /plugins/MyPlugin/lang/en.json).

    Adding translations for other languages

    This is as easy as creating new files in the lang subdirectory of your plugin. The filename consists of a 2 letter ISO 639-1 language code completed by the extension .json. This means German translations go into a file named de.json, French ones into a file named fr.json. To see a list of languages you can use have a look at the /lang directory.

    Reusing translations

    As mentioned Piwik comes with quite a lot of translations. You can and should reuse them but you are supposed to be aware that a translation key might be removed or renamed in the future. It is also possible that a translation key was added in a recent version and therefore is not available in older versions of Piwik. We do not currently announce any of such changes. Still, 99% of the translation keys do not change and it is therefore usually a good idea to reuse existing translations. Especially when you or your company would otherwise not be able to provide them. To find any existing translation keys go to Settings => Translation search in your Piwik installation. The menu item will only appear if the development mode is enabled.

    Translations in PHP

    Use the Piwik::translate() function to translate any text in PHP. Simply pass any existing translation key and you will get the translated text in the language of the current user in return. The English translation will be returned in case none for the current language exists.

    $translatedText = Piwik::translate('MyPlugin_BlogPost');

    Translations in Twig Templates

    To translate text in Twig templates, use the translate filter.

    {{ 'MyPlugin_BlogPost'|translate }}

    Contributing translations to Piwik

    Did you know you can contribute translations to Piwik ? In case you want to improve an existing translation, translate a missing one or add a new language go to Piwik Translations and sign up for an account. You won’t need any knowledge in development to do this.

    Advanced features

    Of course there are more useful things you can do with translations. For instance you can use placeholders like %s in your translations and you can use translations in JavaScript as well. In case you want to know more about those topics check out our Internationalization guide. Currently, this guide only covers translations but we will cover more topics like formatting numbers and handling currencies in the future.

    Congratulations, you have learnt how to make your plugin multilingual !
