• How to get your Piwik plugin translated in many languages ?

  8 septembre 2015, par Stefan Giehl — Community, Development, Plugins

  About a year ago we introduced the Piwik Marketplace to make it easy for developers to share their plugins with all Piwik users.

  As Piwik is currently available in 54 languages we would love to have as many plugins as possible available in at least a few of those languages.

  Currently most plugins on the Marketplace are only available in English and sometimes some other languages. To improve this situation, we offer plugin developers the possibility to use the power of our translators community to get their plugins translated.

  Some plugin developers are already using this service and some very popular plugins like BotTracker or CustomOptOut have already been translated in more than 10 languages !

  Getting translations for your plugin

  As long as you are developing an open source plugin hosted on Github, you may get in touch with us (translations@piwik.org) in order to get your plugin translated by the Piwik translators community.

  You will need an account on Transifex.com. If you use Transifex with a social login, please ensure to set a password in your account settings. This will be required for fetching new translations into your plugin repository.

  Importing your plugin’s strings in the translation platform

  While doing the initial setup for your plugin, we will import your english translation file (en.json) in your Github plugin repository and we will configure an auto-update for this file. Source strings on Transifex will automatically synchronise with your plugin repository. When you change any string in your en.json translation file, the updated English strings will automatically be imported in Transifex.

  How to fetch your plugins translations into your repository

  As soon as we have set up your plugin within our project Piwik on Transifex and there are new translations available, you will be able to update your plugin translations using the Piwik console. You will need a locally installed Piwik with development mode enabled, and your plugin installed. To update the translations go to the Piwik directory on your development box and execute the following command :

  ./console translations:update -u {YourTransifexUserName} -p {YourTransifexPassword} -P {YourPluginName}

  We are looking forward to seeing your Piwik plugins available in more languages ! For more information, check out our Translations plugin developer guide.

  Happy hacking,

• FFMPEG API : decode MPEG to YUV frames and change these frames

  12 mars 2015, par Vaigard

  I need save all frames from MPEG4 or H.264 video to YUV-frames using C++ library. For example, in .yuv, .y4m or .y format. Then I need read these frames like a digital files and change some samples (Y-value). How can I do it without convert to RGB ?

  And how store values of AVFrame->data ? Where store Y-, U- and V-values ?

  Thanks and sorry for my English=)

• 【CV】use ffmpeg to process video through cmd in python

  26 novembre 2019, par user66124

  when reading the segment generation function in https://github.com/zhengshou/scnn, I encounter the following sentence :

  cmd = '../lib/preprocess/ffmpeg -i ' + input_video + ' -r ' + str(framerate) + ' -f image2 ' + framedir + videoname +'/%06d.jpg' + ' 2>' + framedir + 'frame_extract.log'

  Is there anyone know the meaning of each part ?
