  • Qualité du média après traitement

    21 juin 2013, par

    Le bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
    Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

  • When using ffmpeg.exe to create video from sequence of images the result is avi file that show green color why ?

    9 janvier 2014, par user3163653

    In Form1 im taking screenshots of my screen I checked they are ok i save them to the hard disk and see they are ok.

    private void timer1_Tick(object sender, EventArgs e)
           {

               using (bitmap = (Bitmap)ScreenCapture.CaptureScreen(true))
               {

               Image mScreenImage = new Bitmap(Screen.PrimaryScreen.Bounds.Width,
                                        Screen.PrimaryScreen.Bounds.Height);
               Graphics g = Graphics.FromImage(bitmap);
               g.CopyFromScreen(0, 0, 0, 0, new Size(bitmap.Width, bitmap.Height));
               g.Dispose();
                   bitmap.Save(@"D:\Testbmp\" + counter.ToString("D6") + ".jpg", ImageFormat.Jpeg);
                   counter++;
               ffmp.PushFrame((Bitmap)mScreenImage);

               }

           }

    Then in the new class ffmp im using pipe to get the screenshots and build the avi file in real time :

           {
               p.Close();
           }
       }
    }

    This is the arguments im using now :

    psi.Arguments = @"-f rawvideo -pix_fmt yuv420p -video_size 1920x1080 -i \\.\pipe\mytestpipe -map 0 -c:v mpeg4 -r " + BitmapRate + " " + outPath;

    Before that I tried to use libx264 instead the mpeg4 but it didn't create the avi file good.
    The problem is that the avi file on the hard disk when I play it show just green color.
    I can play any other avi files on my hard disk but when playing this avi file I see green.

    enter image description here

    And this is what I see when im playing the avi file :

    enter image description here

    I tried to use Gspot to find if I need any codec to install and this is what I see :

    enter image description here

    And I have ffdshow installed already so what should I do now ?

  • Top 5 Web Analytics Tools for Your Site

    11 août 2023, par Erin — Analytics Tips

    At the start of July 2023, Universal Analytics (UA) users had to say goodbye to their preferred web analytics tool as Google discontinued it. While some find Google Analytics 4 (GA4) can do what they need, many GA4 users are starting to realise GA4 doesn’t meet all the needs UA once fulfilled. Consequently, they are actively seeking another web analytics tool to complement GA4 and address those unmet requirements effectively.

    In this article, we’ll break down five of the top web analytics tools on the market. You’ll find details about their core capabilities, pricing structures and some noteworthy pros and cons to help you decide which tool is the right fit for you. We’ve also included some key features a good web analytics tool should have to give you a baseline for comparison.

    Whether you’re a marketing manager focused on ROI of campaigns, a web analyst focused on conversions or simply interested in learning more about web analytics, there’s something for you on this list.

    What is a web analytics tool ?

    Web analytics tools collect and analyse information about your website’s visitors, their behaviour and the technical performance of your site. A web analytics tool compiles, measures and analyses website data to give you the information you need to improve site performance, boost conversions and increase your ROI.

    What makes a web analytics tool good ?

    Before we get into tool specifics, let’s go over some of the core features you can expect from a web analytics tool.

    For a web analytics tool to be worth your time (and money), it needs to cover the basics. For example :

    • Visitor reports : The number of visitors, whether they were unique or repeat visitors, the source of traffic (where they found your website), device information (if they’re using a desktop or mobile device) and demographic information like geographic location
    • Behaviour reports : What your visitors did while on your site, conversion rates (e.g., if they signed up for or purchased something), the pages they entered and exited from, average session duration, total time spent on a page and bounce rates (if they left without interacting with anything)
    • Technical information : Page loading speed and event tracking — where users are clicking, what they’re downloading or sharing from your site, if they’re engaging with the media on it and how far down the page they’re scrolling
    • Marketing campaign information : Breakdowns of ad campaigns by provider, showing if ads resulted in traffic to your site and lead to an eventual sale or conversion
    • Search Engine Optimisation (SEO) information : Which keywords on which pages are driving traffic to your site, and what search engines are they coming from
    • Real-time data tracking : Visitor, behaviour and technical information available in real-time, or close to it — allowing you to address to issues as they occur
    • Data visualisation : Charts and graphs illustrating the above information in an easily-readable format — helping identify opportunities and providing valuable insights you can leverage to improve site performance, conversion rates and the amount of time visitors spend on a page
    • Custom reporting : Create custom reports detailing the desired metrics and time frame you’re interested in
    • Security : User access controls and management tools to limit who can see and interact with user data
    • Resources : Official user guides, technical documentation, troubleshooting materials, customer support and community forums
    Google Analytics 4 dashboard

    Pros and Cons of Google Analytics 4

    Despite many users’ dissatisfaction, GA4 isn’t going away anytime soon. It’s still a powerful tool with all the standard features you’d expect. It’s the most popular choice for web analytics for a few other reasons, too, including :

    • It’s free to use
    • It’s easy to set up
    • It has a convenient mobile app
    • It has a wealth of user documentation and technical resources online
    • Its machine-learning capabilities help predict user behaviour and offer insights on how to grow your site
    • It integrates easily with other Google tools, like Google Search Console, Google Ads and Google Cloud

    That said, it comes with some serious drawbacks. Many users accustomed to UA have reported being unhappy with the differences between it and GA4. Their reasons range from changes to the user interface and bounce rate calculations, as well as Google’s switch from pageview-focused metrics to event-based ones. 

    Let’s take a look at some of the other cons :

    Now that you know GA4’s strengths and weaknesses, it’s time to explore other tools that can help fill in GA4’s gaps.

    Top 5 web analytics tools (that aren’t Google)

    Below is a list of popular web analytics tools that, unless otherwise stated, have all the features a good tool should have.

    Adobe Analytics

    Screenshot of the landing page for Adobe's web analytics tool

    Adobe is a trusted name in software, with tools that have shaped the technological landscape for decades, like Photoshop and Illustrator. With web design and UX tools Dreamweaver and XD, it makes sense that they’d offer a web analytics platform as well.

    Screenshot of Mixpanel's product page

    Mixpanel’s features are heavily geared toward e-commerce companies. From the moment a visitor lands on your website to the moment they enter their payment details and complete a transaction, Mixpanel tracks these events.

    Similar to GA4, Mixpanel is an event-focused analytics platform. While you can still track pageviews with Mixpanel, its main focus is on the specific actions users take that lead them to purchases. Putting your attention on this information allows you to find out which events on your site are going through the sales funnel.

    HubSpot Marketing

    Screenshot of Hubspot Marketing's main page

    HubSpot is a customer relationship management (CRM) platform with marketing, sales, customer service, content management system (CMS) and operations tools. This greater ecosystem of HubSpot software allows you to practically run your entire business in one place.

    Even though HubSpot Marketing isn’t a dedicated web analytics tool, it provides comparable standard metrics as the other tools on this list, albeit without the more advanced analytical metrics they offer. If you’re already using HubSpot to host your website, it’s definitely worth consideration.

    • 24/7 customer support

    • Some users report customer support is unhelpful

    Mobile app : Yes

    Kissmetrics

    Screenshot of the landing page of web analytics tool Kissmetrics

    Kissmetrics is a web analytics tool that is marketed toward SaaS and ecommerce companies. They label themselves as “person-based” because they combine event-based tracking with detailed user profiles of the visitors to your site, which allows you to gain insights into customer behaviour. 

    With user profiles, you can drill down to see how many times someone has visited your site, if they’ve purchased from you and the steps they took before completing a sale. This allows you to cater more to these users and drive growth.
