• Flutter FFMPEG : Error setting profile baseline

  9 avril 2021, par Raj Dhakad

  Flutter-ffmpeg unable to set profile parameter. (I need to use profile so the rendered video can be played on WhatsApp).

  


  I am converting.bmp images into a mp4 video. Other I have tested other praramets and the work great it's only -profile:v which seems to have some problem.

  


  Everything works fine unless I use -profile:v baseline.

  


  void _runFFmpeg() async {
    var dir = await getApplicationDocumentsDirectory();
    var output = await getExternalStorageDirectory();
    String videoSize = '${ImageWidth}x$ImageSize';
    print("${ImageWidth}x$ImageSize");
    var arguments = [
      "-y", // replace output file if it already exists
      "-framerate", "30", // framrate
      "-video_size", videoSize,
      "-pixel_format", "yuv420p",
      "-i", "${output.path}/frame_%d.bmp",  
      "-profile:v", "baseline",
      "-level", "3.0",
      "${output.path}/test.mp4"
    ];
    
    _flutterFFmpeg
        .executeWithArguments(arguments)
        .then((rc) => print("FFmpeg process exited with rc $rc"));
 

    print("Done Rendering");
  }

• Introducing Matomo SEO Web Vitals

  13 septembre 2021, par Ben Erskine — About, Analytics Tips, Plugins

  SEO Web Vitals track your critical website performance metrics and are a core element of SEO best practice. 

  Start using Matomo SEO Web Vitals to monitor your website performance, optimise your visitor experience, improve your search result rankings, and see how your site compares to your competitors.

  

  What are SEO Web Vitals ?

  Web Vitals are made up of a number of important metrics, such as your website’s page speed and loading performance, these metrics all play an important role in search engine optimisation. 

  The more technical terms for these metrics are Page Speed Score, First Contentful Paint (FCP), Final Input Delay (FID), Last Contentful Paint (LCP) and Cumulative Layout Shift (CLS).

  Why should you use SEO Web Vitals ?

  SEO Web Vitals are being used more and more by search engines such as Google to rank websites so they help ensure a great page experience for users who arrive via links from their search results. 

  By monitoring your SEO Web Vitals you can see how good or bad a single page performs and then prioritise the optimisation of strategically important pages to help improve the ranking position within search engine results.

  For ease of use you can receive regular reports in your email inbox and you can configure custom alerts to automatically notify you when a page score changes significantly. This saves time by not having to check page performance scores manually while ensuring you will be notified should there be any important change that needs to be actioned.

  You should use SEO Web Vitals to understand how your site performance is impacting your overall visitor experience.

  Four key benefits of using SEO Web Vitals :

  Improve your search result rankings

  • SEO Web Vitals are a core element of SEO best practice and directly impact your search rankings.
  • Pages that load quickly and are more stable deliver a better user experience, so they’re ranked higher by search engines.

  Optimise your website visitor experience

  • Know how quickly pages on your website load to ensure you deliver an optimal visitor experience.
  • Identify page stability issues and implement the changes needed to enhance your visitor experience.

  Automate your website performance monitoring

  • Have peace of mind knowing if your metrics decrease, you can find and fix the root cause quickly.
  • Configure performance alerts and get automated reports sent to you.

  Incorporate website performance into your competitor analysis

  • These performance metrics are essentially open for anyone to inspect, so you can measure and benchmark your site against competitors. 

  How can I improve my SEO Web Vitals ?

  There are so many ways to improve these performance metrics, here are five of the common contributing factors.

  1. Your page speed score is a weighted average of your other performance metrics, so focus on improving the underlying metrics that contribute to this score.
  2. Ensure you use a high quality web host with an appropriate plan for your level of traffic to help improve your FCP time.
  3. Try removing large elements that aren’t required on your page to improve your LCP time.
  4. Optimise against Total Blocking Time to Improve your FID score.
  5. Consider using a Layout Shift Debugger to improve Your CLS Score

• How to force different version for arch package dependency

  27 mars 2022, par Gigas002

  I'm building the vangers's game engine as package for AUR. Readme's recommended platform for building is ubuntu, which repos has ffmpeg version 4.4. Arch's ffmpeg is 5.0, with ffmpeg4.4 as a separate package. The problem is, that the game seems to be unbuildable with 5.0 version. How can I force the package to be built with exactly ffmpeg4.4's libraries, but not 5.0 in PKGBUILD file ?
