  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • ffmpeg converting JPG slideshow to H264

    22 décembre 2018, par phol

    I am trying to convert a set of jpg files to a slideshow with varying durations using ffconcat

    output.txt contents :

    ffconcat version 1.0
    file slide_0001.jpg
    duration 0.163
    file slide_0002.jpg
    duration 0.533
    file slide_0003.jpg
    duration 1.067
    file slide_0004.jpg
    duration 0.533
    file slide_0005.jpg
    etc.

    FFmpeg command :

    ffmpeg -i output.txt output.mkv

    I also tried :

    ffmpeg -i output.txt -c:v copy output.mkv

    However, when converting, the colours of the images become skewed.
    White becomes pink / purple and dark green becomes light green.
    The same happens when choosing different codecs and containers.
    Is there a way to solve this ?

    EDIT :
    I performed the same conversion again. I attached the log output as requested.
    However, in the meantime I have figured out that converting without ffconcat duration and then altering timecodes with mp4fpsmod is more efficient in terms of storage (3 vs 40 MB) and gives less issues in different players. The result is nonetheless the same : colours are still wrong, both on my workstation (Ubuntu 18.04) and laptop (macOS Mojave).

    I tried to alter things with pix_fmt and -vf format as can be seen in the second log output. This did not solve the problem.

    Background info :
    The input jpg files are from a lecture recording made with MediaSite, which has both a video stream for the room as well as this slideshow stream for the slides.

  • ffmpeg converting JPG slideshow to MKV

    17 décembre 2018, par phol

    I am trying to convert a set of jpg files to a slideshow with varying durations using ffconcat

    output.txt contents :

    ffconcat version 1.0
    file slide_0001.jpg
    duration 0.163
    file slide_0002.jpg
    duration 0.533
    file slide_0003.jpg
    duration 1.067
    file slide_0004.jpg
    duration 0.533
    file slide_0005.jpg
    etc.

    FFmpeg command :

    ffmpeg -i output.txt output.mkv

    I also tried :

    ffmpeg -i output.txt -c:v copy output.mkv

    However, when converting, the colours of the images become skewed.
    White becomes pink / purple and dark green becomes light green.
    The same happens when choosing different codecs and containers.
    Is there a way to solve this ?

    EDIT :
    I performed the same conversion again. I attached the log output as requested.
    However, in the meantime I have figured out that converting without ffconcat duration and then altering timecodes with mp4fpsmod is more efficient in terms of storage (3 vs 40 MB) and gives less issues in different players. The result is nonetheless the same : colours are still wrong, both on my workstation (Ubuntu 18.04) and laptop (macOS Mojave).

    I tried to alter things with pix_fmt and -vf format as can be seen in the second log output. This did not solve the problem.

    Background info :
    The input jpg files are from a lecture recording made with MediaSite, which has both a video stream for the room as well as this slideshow stream for the slides.

  • Why Matomo is a serious alternative to Google Analytics 360

    12 décembre 2018, par Jake Thornton — Marketing

    There’s no doubt about it, the free version of Google Analytics offers great value when it comes to making data-driven decisions for your business. But as your business starts to grow, so does the need for a more powerful web analytics tool.

    Why would I need to use a different web analytics tool ? It’s because Google Analytics (free version) is very limited when it comes to meeting the needs of a fast growing business whose website plays a pivotal role in converting its customers.

    This is where the Google Analytics 360 suite comes in, which is designed to meet the needs of businesses looking to get more accurate and insightful metrics.

    So what’s holding a growing business back from using Google Analytics 360 ?

    While GA360 sounds like a great option when upgrading your web analytics platform, we have found there are three core reasons holding businesses back from taking the leap :

    • Businesses can’t bear to swallow the US$150,000+ price tag (per year !) that comes with upgrading
    • Businesses can’t rely on GA360 to give them all the insights they need
    • Businesses want more control and ownership of their data

    Thankfully there are (only a few) alternatives and as the leading open-source alternative to Google Analytics, we hope to share insights on why Matomo Analytics can be the perfect solution for anyone at this crossroads in their web analytics journey.

    First, what does Google Analytics 360 offer that Google Analytics (free) doesn’t ?

    There’s no doubt about it, the GA360 suite is designed for larger sized businesses with demanding data limits, big budgets to use across the Google Marketing Platform (Google Adwords, DoubleClick etc.) and to get more advanced reporting visualisations and options.

    Data Sampling

    Data sampling is the elephant in the room when it comes to comparing GA360 with the freemium version. This is an entire article in its own right but at a basic level, Google Analytics samples your data (makes assumptions based on patterns) once the number of traffic visiting your website reaches a certain limit.

    Google Analytics provides the following information :

    Ad-hoc queries of your data are subject to the following general thresholds for sampling :

    Analytics Standard : 500k sessions at the property level for the date range you are using

    Analytics 360 : 100M sessions at the view level for the date range you are using

    In short, sampled data means inaccurate data. This is why as businesses grow, GA360 becomes a more attractive prospect because there’s no point making data-driven business decisions based on inaccurate data. This is a key weapon Google uses when selling to large businesses, however, this may not seem as concerning if you’re a small business within the sampled data range. For small businesses though, make sure you know the full extent of how this can affect your metrics, for example, your ecommerce data could be sampled, hence your GA reporting not matching your CRM/Ecommerce store data.

    Benefit of using Matomo : There is no data sampling anywhere in Matomo Analytics, that’s why we say 100% Accurate Data reporting across all plans.

    All Matomo data is 100% accurate

    Integration with the Google Marketing Platform

    Yes ok, we’ll admit it, GA does a great job at integrating seamlessly with its own products like Google Ads, Google Optimize etc. with a touch of Salesforce integration ; while GA360 takes this to another level compared to it’s freemium version (integration with Google Search 360, Google Display & Video 360 etc.)

    But… what about non-Google advertising platforms ? Well with Google being a dominant leader as a search engine, web browser, email provider, social media channel ; sometimes Google needs to keep its best interests at heart.

    Google is an online advertising giant and a bonus of Google Search 360 is that you can integrate your Bing Ads, Baidu and Yahoo Japan Search campaigns but that’s about it when it comes to integrations from its direct competitors. 

    Benefit of using Matomo : No biased treatment. You can integrate your Google, Yahoo and Bing search consoles for accurate search engine reporting, and in early 2019, Matomo will be releasing a Google Ads, Bing Ads and Facebook Ads Manager integration feature.

    Roll-Up Reporting
    Roll-Up Reporting for Matomo Nalytics

    Roll-up reporting lets you combine multiple accounts and properties into one view. This is a great benefit when upgrading from GA freemium to GA360. For example, if you’re a digital agency with multiple clients or you manage multiple websites under the one account, the roll-up reporting feature is wonderful when you need to combine data and reporting, instantly.

    Benefit of using Matomo : Matomo’s got this covered ! Roll-up reporting is available in the Matomo Business package (starting at $29 per month) for cloud hosting or you can purchase as a Premium Feature for On-Premise starting at $99 per year.

    Staying in full control of your data

    Who would have thought that one of biggest reasons people choose Matomo isn’t because of anything that leads to a higher ROI, but for the fact that users want more control of their data.
    100% Data Ownership with Matomo

    Matomo’s philosophy around data ownership is simple, you own your data, no one else. If you choose to host Matomo Analytics On-Premise then you are in complete control because your data is stored on your own servers where no one can gain access to it in whichever country you choose.

    So what about when you cloud host Matomo ? For users who don’t have the technical knowledge to host Matomo On-Premise, you can still have 100% data ownership and fully respect your user’s privacy when choosing to host Matomo Analytics through our cloud service.

    The difference between cloud hosting Matomo Analytics vs Google Analytics is that when you choose Matomo, we acknowledge you own the data and we have no right to access it. This means we can’t on-sell it to third-parties, we can’t claim ownership of it, you can export your data at anytime (how awesome is that !) and you can migrate between cloud hosting and hosting on-premise for ultimate flexibility whenever you want.

    Matomo also prides itself in allowing its users to be GDPR compliant with ease with a powerful GDPR Manager.

    Businesses can’t rely on Google Analytics 360 to give them all the insights they need

    Unlike Google Analytics 360, Matomo blends its Premium Web Analytics platform with Conversion Optimization features to allow its users to fully evaluate the user-experience on your website.

    Matomo is designed to be a complete analytics platform, meaning you have everything you need all in the one place which gives you greater insights and better business outcomes.

    By having one tool for all your features you can integrate metrics, have one single view for all your data and it’s easy to use.

    Enhanced SEO – Get more insights into the performance of your search campaigns with unbiased search engine reporting, keyword ranking positions, integration with multiple search consoles and crawling stats.

    Tag Manager – A powerful open-source Tag Manager tool to embed your third-party marketing tags. By being open-source and with our commitment to giving you 100% data ownership, you can always ensure you are in full control.

    Just putting it out there ...

    Google leads the market with its freemium tool which offers great insights for businesses (fyi – Matomo has a forever free analytics tool too !), but when it comes to upgrading to get accurate reporting (kind of a big deal), owning your own data (a huge deal !) and having a complete range of features to excel ROI for your business, Matomo Analytics is often a preferred option to the Google Analytics 360 suite.

    Matomo is designed to be easy to use, is fully flexible and gives users full peace of mind by respecting user privacy. Want to learn more about the benefits of Matomo ?
