• How to burn in subtitles onto a webm video with ffmpeg ?

  7 mai 2014, par IcanFLY

  I am trying to set up a livestream with ffserver and ffmpeg. The problem is I am using webm, and I need to burn in subtitles, which are located in a mkv. I am not quite sure how to do this, but here is my ffmpeg config (ffstream.sh) that I am using :

  #Livestream script for FFMpeg/FFServer
  
  FPS=24                                          # Stream FPS.
  
  GOP=48                                          # GOP Should be double of FPS.
  
  THREADS=4                                       # How many threads.
  
  DEADLINE=realtime                               # Speed preset, realtime is fastest.
  
  FRAMELAG=16                                     # How many frames to seek ahead (max 25)
  
  QMAX=52                                         # More = less quality.
  
  QMIN=10                                         # Less = more quality.
  
  VBITRATE=1M                                     # Target Bitrate.
  
  BITRATE=3000k                                   # Bitrate.
  
  AUDIBR=48k                                      # Audio Bitrate.
  
  SERVER=<myserver>:8090/feed.ffm                 # Server stream endpoint.
  
  LOGLEVEL=verbose                                # Logging verbosity level.
  
  
  
  for f in $@; do ffmpeg -re -i $f\
  
          -vf subtitles=$f\
  
          -g $GOP -loglevel $LOGLEVEL\
  
          -c:v:0 libvpx  -threads $THREADS -b:v $BITRATE -vb $VBITRATE -bufsize $BITRATE\
  
          -qmax $QMAX -qmin $QMIN -deadline $DEADLINE -lag-in-frames $FRAMELAG\
  
          -c:a libvorbis -b:a $AUDIBR\
  
          "http://$SERVER"
  
  done
  
  </myserver>

  Everything connects fine and I can get audio and video to play, however I cannot seem to get the subtitles to show up. Here is my output (I quit out of it) :

  Stream mapping:
  
    Stream #0:1 -> #0:0 (flac -> libvorbis)

  Also here is my ffserver config, not sure if there is something in here stopping the subtitles from showing up :

  # Redirect index.html to the appropriate site

  Any help on how to do this, would be grateful.

• Why do you need analytics for your WordPress ?

  7 avril 2020, par Joselyn Khor — Analytics Tips, Plugins
  Not many people know this, but having a WordPress analytics tool gives you a competitive advantage. It’s also essential to the growth of your website. For many businesses, websites are the main driver of revenue and sales. In the case of blogs, it’s your first chance to make a lasting impression.

  Now, maybe you’ve heard of Google Analytics or even the privacy-friendly alternative, Matomo Analytics, but have never tried them ? These are analytics platforms that help you understand your website traffic and visitors. (You can find these platforms as plugins in the WordPress directory !)

  They’re important because the insights you get help you determine what changes to make to improve your website. Without them you could face a tougher time figuring out what’s working, what the issues are (and solving them before they get out of hand), and making sure you’re taking your website in the right direction. 

  WordPress analytics gives you an understanding of what’s actually going on.

  How does a WordPress analytics plugin benefit your website ?

  What this means for you is getting a toolkit to learn how to get more sales or followers and subscribers (aka conversions in analytics terms). 

  By getting insights into user behaviour, content performance, and how you can optimise your website, you can reach more of your goals, like increasing sales or growing your audience.

  A WordPress analytics tool helps you get more traffic to your site

  You get a range of features which tell you which acquisition channels are working for you like – social media, search engines, and other websites mentioning you. This helps you make an informed decision on where to focus energies (or spend) to get more of the ideal people coming through to your website. 

  

  Example : Looking through your acquisition channels and seeing that Reddit drives a lot of traffic through to your website. Since this channel seems to be working for you, you could then spend more time on Reddit posts to increase traffic.

  But getting more traffic isn’t all there is to it. Once they land on your site, you want them to stay for a little longer so they are intrigued by what you’re offering. Be it a product, or awesome content.

  Which leads us to …

  Increasing engagement by learning about visitor behaviour

  When you get a solid number of visitors on your website, it’s good to then learn about how they behave on your site. A WordPress analytics tool helps with engagement since you’re seeing what’s appealing to them, and what isn’t.

   Increasing engagement is good for a few reasons. 

  • You end up speaking the language of your readers. 
  • You can make a difference with the information you’re putting out. 
  • You get loyal customers and believers in your organisation. 

  With more engaged visitors, you can build trust with them and eventually be able to convince them that your product, service, or blog is needed in their lives.

  

  Example : Looking through entry and exit pages to see what first impression is making them stay, and what impression is making them leave. This helps you redirect efforts to give your website a better chance of getting visitors to stay longer.

  Improving your content and engagement can lead to more conversions

  After you get visitors engaged, it’s time to convert. 

  Whether you have an ecommerce site or freelance blog, you’ll need to know how to boost conversions. This simply means getting people to achieve more of the actions you’re wanting them to take on your site. Like subscribing to your newsletter or adding items to a cart.

  With conversion optimization features, you’re finding out how well your website is designed to get buyers through a journey to conversion. 

  

  Example : Say you’ve created a newsletter sign up page, but you’re not getting as many sign ups as you’d like. With a web analytics tool, you can look into it further. A funnels feature could tell you how they’re getting to that page. If people can’t find your page, that could be reason for low conversion rates. Or, maybe you are getting people landing on this page, but you can’t tell why they’re not signing up. Try setting up a heatmap to see how far they’re scrolling down your page to the sign up section. Through these conversion optimization features, you can make tweaks that significantly improve conversions.

  So, how does the Matomo Analytics for WordPress plugin help with all of this ?

  

  Matomo Analytics for WordPress is a free web analytics plugin that gives you access to all the features mentioned above, right in your own WordPress dashboard. It’s completely free to use and is handy for users of all skill levels. From beginners right through to advanced analysts. 

  You get to move through all the stages to increase traffic, increase engagement, and convert. By using Matomo for WordPress, you put yourself in a better position to track all the needed data from your WordPress website. 

  You have this toolkit to improve your website for free, with a few clicks ! 

  By getting useful insights like visitors, acquisitions, bounce rates etc. you gain a new perspective on how to improve your website so it’s better at doing what you created it to do. Getting these insights also means giving yourself the confidence to do what’s best for your website in a data-driven way. 

  With all this knowledge, you can be competitive, or grow enough that you’re leaving your competitors in the dust. 

• Switch to Matomo for WordPress from Google Analytics

  10 mars 2020, par Joselyn Khor — Plugins, Privacy
  While Google Analytics may seem like a great plugin option on the WordPress directory, we’d like to present a new ethical alternative called Matomo for WordPress, which gives you 100% data ownership and privacy protection.

  Firstly what does Google Analytics offer in WordPress ?

  When you think of getting insights about visitors on your WordPress (WP) sites, the first thing that comes to mind might be Google Analytics. Why not right ? Especially when there are good free Google Analytics plugins, like Monster Insights and Site Kit. 

  These give you access to a great analytics platform, but the downside with Google Analytics is the lack of transparency around privacy and data ownership.

  

  Matomo Analytics for WordPress is an ethical alternative to Google Analytics for WordPress

  If you’re more interested in a privacy-respecting, GDPR compliant alternative, there’s now a new option on the WP plugins directory : Matomo Analytics – Ethical Stats. Powerful Insights. 

  It’s free and can be considered the #1 ethical alternative to Google Analytics in terms of features and capabilities. Why is it important to choose a web analytics platform that respects privacy ?

  

  Risk facing fines for non-GDPR compliance and privacy/data breaches

  In Europe there’s an overarching privacy law called GDPR which provides better privacy protection for EU citizens on the web. 

  Websites need to be GDPR compliant and follow rules governing how personal data is used or risk facing fines up to 4% of their yearly revenue for data/privacy breaches or non-compliance. Even if your website is based outside of Europe. If you have visitors from Europe, you can still be liable.

  

  In the US, there isn’t one main privacy law, there hundreds on both the federal and state levels to protect the personal data (or personally identifiable information) of US residents – like the California Consumer Privacy Act (CCPA). There are also industry-specific statutes related to data privacy like HIPAA.

  To protect your website from coming under fire for privacy breaches, best practise is to find platforms that are privacy and GDPR compliant by design. 

  When you own your own data – as with the case of Matomo – you have control over where data is stored, what you’re doing with it, and can better protect the privacy of your visitors.

  At this point you may be asking, “what’s the point of an analytics platform if you have to follow all these rules ?”

  The importance of analytics for your WordPress site

  • Figuring out how your audience behaves to increase conversions
  • Setting, tracking and measuring conversion goals
  • Being able to find insights to improve and optimize your site 
  • Making smarter, data-driven decisions so your company can thrive, rather than risk being left behind

  Analytics is used to answer questions like :

  • Where are your website visitors coming from (location) ?
  • How many people visit your website ?
  • Which are the most popular pages on your site ?
  • What sources of traffic are coming to your site (social, marketing campaigns, search) ?
  • Is your marketing campaign performing better this month compared to last ?

  Matomo can answer all of the above questions. BONUS : On top of that, with Matomo you get the peace of mind knowing you’re the only one who has access to those answers.
