  • Piwik 3 Development Update #1 – New UI design, API changes & release date

    1er septembre 2016, par Thomas Steur — Community, Development

    Over the last months, we have been actively working on the Piwik 3 release and we want to introduce you to the changes that we have done so far. They include a new and modern UI redesign, new widgets for your dashboard, and technical improvements under the hood.

    New Piwik 3 UI

    Based on Material Design we have revamped the user interface which is now more responsive, more usable and faster. While the UI is not yet finished, we invite you to check it out already and to let us know what you think.

    This new Piwik material design is a visual language that synthesizes classic principles of good design with the innovation and possibility of technology and science.

    More responsive

    Piwik 3 will look and feel much better on your mobile phone and tablet. Many elements have been improved : the menus, the segment editor and dashboard selector, the widgets, the settings pages and most other pages so you can fully experience and enjoy Piwik on any device !

    Improved usability

    We have updated the menu structure, the dashboard selector as well as the footer in reports to make your life easier when using Piwik. We love to keep these complicated things simple. There are also many other tiny improvements that you will appreciate.

    The Zen Mode lets you view in full screen your analytics reports and dashboards. Users love this feature and it can now be accessed by pressing “z” key.

    Faster

    To make the Piwik interface faster, we have refactored most of our CSS, HTML and JavaScript and moved more and more of our code into the client. As a result, Piwik now needs to reload the page much less often ! For example when you change the date or change the segment, Piwik will now load the reports instantly. To improve performance even further, Piwik will now load multiple reports on a single page in parallel.

    Native fonts

    Over the last months more and more web services have started using system fonts, and so will Piwik 3. System fonts look better, improve language support and give you a more native, familiar feeling.

    For more details and screenshots have a look at the pull request for the Piwik 3 UI update.

    New widgets

    With the “Latest Piwik Plugin Updates” widget you won’t miss any newly added or updated plugin anymore. This will help you learn about and discover the useful plugins and themes available on the Marketplace.

    Super users can now see at a glance the current state of the Piwik system, thanks to the new “System Check” and “System Summary” widgets.

    API Changes

    Piwik is the leading open analytics platform, highly customisable and extensible thanks to a flexible plugins architecture and a design based on APIs. In this new major Piwik 3 release, we significantly improve the foundation of our open platform and several of its core APIs.

    The new Widgets and Reporting API makes it possible to add reports and widgets to any existing reporting page. In the past, reporting pages had to be created manually which was time consuming and it was hard to maintain a consistent look across different reporting pages. Now reporting pages are generated automatically by the Piwik platform.

    The Plugin Settings API was changed to improve performance and to let plugin developers customize the Websites Manager. This is one step towards our goal to let users not only manage websites but also mobile apps, cars, coffee machines or any other thing.

    To see a full list of changes in the Piwik 3 analytics platform, have a look at the developer changelog.

    Developer docs

    The Piwik Developer Zone is full of guides and API references to help developers understand, integrate and extend Piwik. As some APIs have changed in the Piwik 3 release it is now possible to select the Piwik version in the top right corner of the developer zone.

    We are updating guides for Piwik 3 and added a Piwik 2 -> Piwik 3 Migration Guide for plugin developers. Many other guides were updated such as Menus, Custom Report and Widgets.

    Release date

    The first Piwik 3 beta release will be available in the next four weeks. Beta testers automatically receive the update if they are subscribed to the “Latest Beta” release channel. The final Piwik 3 release will be ready before the end of the year. If you want to give it a try, you can either use Piwik from Git and check out the “3.x-dev” branch, or download Piwik 3 from GitHub.

    Closing thoughts

    With faster & more beautiful reports, better APIs and more stability, Piwik 3 is a big step forward for all Piwik users. As our mission is to create, as a community, the leading international open source web analytics platform that gives every user full control of their data, we are very excited to introduce you to this upcoming release.

    We now offer Custom Development services if you like to sponsor a new feature or bug fix, or if you have any custom requirements. And if you use Piwik Analytics to grow your business and need quality help, contact the Piwik analytics experts to get started.

    Until our next Piwik 3 dev update, Happy analysis !

  • Adding Gapless Playback information to AAC

    13 juillet 2018, par StaticBR

    im currently trying to develop an Video / Audio encoding pipline.
    My goal is it to encode mp4 files containing an h264 video track and an AAC audio Track. These files should be played one after another without any gaps in between.

    Currently im converting the videos with ffmpeg.
    Unfortunately my input files are missing the gapless playback metadata, which will be needed for gapless playback of the AAC track.

    Infact im looking for a way to add the iTunSMPB udta comment, as it is needed by the Exoplayer. (See Parser for Details : GaplessInfoHolder.java )

    I could not find a way to add this via ffmpeg ( ffmpeg AAC encoder doc), did i maybe missed something ?

    Even Wikipedia only lists two converters that should be able to do that : Nero Digital and Itunes. But this infomation could be outdated.

    Do anyone of you know a java library or (linux) command that can add this metadata to an mp4 file ?

    I hope some of you might be able to help me.
    Thank you.

  • How to change mp4 aspect ratio to 16:9 using ffmpeg ?

    20 février 2023, par user1788736

    I got an mp4 video that I copy 4 minute of it using ffmpeg. After uploading to YouTube I noticed the uploaded video has black bars on both side of video(right and left side) !After searching for a way to remove those black bars I found that I need to use yt:stretch=16:9 !However,using yt:stretch=16.9 tag will not remove the black bars on iPhone and Samsung smart tv YouTube app !

    



    could an expert help me change the aspect ratio of original mp4 video to 16:9 using ffmpeg (without losing video quality) for re uploading to YouTube ? Thanks in advance ?

    



    I got two types of source with following information :

    



    1)Resolution:720x576 ,Frame rate:25 . Codec:H264 - MPEG-4 AVC(part 10)(avc1),
2)Resolution:848x480 , Frame rate:24.804393,Codec:H264 - MPEG-4 AVC(part 10)(avc1)


    



    ffmpeg code used to trim the original video :

    



       ffmpeg -i orginalVideo.mp4 -ss 00:25:55 -t 00:04:02 -acodec copy -vcodec copy videoForYoutube.mp4
