  • WordPress Analytics plugin WP-Piwik reaches version 1.0.0 (and 50,000 active users)

    29 mai 2015, par André Bräkling — Plugins

    After six years of development, we are proud to announce the 1.0.0 release of our WP-Piwik WordPress plugin !

    Started as a simple plugin to show a selection of statistics within the WordPress dashboard, WP-Piwik has become a full Piwik integration plugin. The plugin automatically adds the Piwik tracking code to your WordPress sites. The plugin displays your analytics reports directly within the WordPress admin panel. WordPress networks (“multisite”), CDN URLs and the Piwik proxy script are also supported.

    According to WordPress.org the plugin is being used by more than 50,000 WordPress sites !

    This article explains how to install WP-Piwik and how to configure it to work with your Piwik instance.

    Install WP-Piwik

    You can get WP-Piwik using WordPress’ plugin management. Login to your WordPress admin dashboard and go to « Plugins » → « Add New ». Enter « WP-Piwik » into the search field at the top right, press enter and next to WP-Piwik choose « Install Now ».

    If you want to use WP-Piwik in your simple WordPress blog you can just click « Activate Plugin » and WP-Piwik will ask you to configure your Piwik connection.

    Running a WordPress network/multisite you can choose to « Network Activate » the plugin after the installation process. In this case, WP-Piwik will be a fully automated feature of your WordPress network automatically tracking your sites in the same Piwik instance in separate Websites.

    Alternatively you can download WP-Piwik manually from the WordPress website and upload all files to your `wp-content/plugins` directory.

    Configure your Piwik connection

    WP-Piwik lets you choose between three connection modes :

    • Self-hosted (HTTP API) : This is the default option for a self-hosted Piwik and should work for most configurations. You just have to know your Piwik URL, which is the URL you enter to access Piwik, and your auth token (see below). WP-Piwik will connect to Piwik using http(s)-requests.
    • Self-hosted (PHP API) : Choose this, if your self-hosted Piwik and WordPress are running on the same machine and you know the full server path to your Piwik instance. Beside the full server path, you also need to know your auth token (see below).
    • Cloud-hosted (Piwik Pro) : If you are using a cloud-hosted Piwik by Piwik Pro, you just need to know your user name and your auth token (see below).

    Setting up WP-Piwik

    To configure WP-Piwik you will need to specify your Authentication token.

    • If the site you want to track in Piwik is already configured in your Piwik, you only need to specify a token_auth for a user with `view` permission.
    • If you want WP-Piwik to create the website in Piwik (or if you use WP-Piwik in network mode which requires to be able to configure your sites), you should specify a token_auth which has Super User access (after the setting up phase is completed you can set the authentication token back to the token of a `view` user).

    To find your token_auth in Piwik, click on your user name in the right right corner of your Piwik dashboard, then click the « API » in the left menu. The API page displays your auth token in a colored box, just behind the “&token_auth=” string. The screenshot below shows the token_auth anonymous, but your real one will be an alpha numerous random string like a1ec31524a8eabc7a546d71d68b28d17.

    That’s it. After you entered your connection data and submitted the form, WP-Piwik will welcome you with some information :

    You can now start to configure WP-Piwik and enable the tracking code. Learn about any setting by clicking on the small question mark sign. If you have any problem configuring or using WP-Piwik feel free to use the WordPress support forum related to WP-Piwik.

    Happy WordPress Analytics !

  • What movie formats and resolutions should be generated to ensure cross-browser/platform compatibility ?

    31 août 2012, par ensnare

    I'm looking to generate web videos from movies taken with my digital camera. What formats should I generate, and at what resolution and bitrate to ensure playback on mobile and desktop devices ?

    Here's what I was thinking :

    Input format : AVI, MOV

    Output format : webm, ogv, mp4
    Output resolutions : 1080p, 720p, 320p

  • Removing both leading and trailing silence from m4a files using ffmpeg

    11 juin 2021, par Tejas Shah

    I have an audio file which has both leading and trailing silence and with the following specifics :

    



    Codec : MPEG AAC Audio (mp4a) Channels : Stereo Sample rate : 44100 Hz Bitrate : 253 kbps

    



    I want to remove the silences AND keep the quality intact.

    



    So far I've tried

    



    ffmpeg -i 1.m4a -af silenceremove=1:0.5:0:1:0.5:0 2.m4a 


    



    This is supposed to remove both the leading and trailing silences. 
But for some reason it doesn't remove the trailing silence. This seems to be a recurring problem. Found the following on another forum.

    



    http://ffmpeg-users.933282.n4.nabble.com/How-to-delete-digital-silence-tp4667256p4667356.html

    



    Also, ffmpeg reduces the bitrate to 128kbps. This I could fix by adding -ab 253k and making the command :

    



    ffmpeg -i 1.m4a -af silenceremove=1:0.5:0:1:0.5:0 -ab 253k 3.m4a 


    



    Now the problem is that the trailing silence isn't removed and when I want to process a batch of files I can't use the same bitrate (like 253kbps ) for every file. I'd like to know how VBR could be used for this case.

    



    I know I can use sox and use the silence and reverse features to trim the silences.

    



    http://digitalcardboard.com/blog/2009/08/25/the-sox-of-silence "Example 3 in this post"

    



    But sox has the following problems :

    



      

    1. It can't handle m4a files, I had to convert all files to mp3.
    2. 


    3. When using the silence filter in sox it caps the bitrate at 128kbps.

      



      sox 1.mp3 2.mp3 silence 1 0.5 1% reverse silence 1 0.5 1% reverse

    4.
