• ffmpeg drawtext support for Tibetan fonts

  19 juin 2020, par A-Circle Zhang

  I'm trying to use ffmpeg drawtext filter to render Tibetan text to videos. But some characters aren't rendered correctly.

  



  for example :

  



  


  སྤྱི་སྟེགས

  


  



  Expected render output

  



  some characters which is.. vertically too long, are not rendered correctly :

  



  Actual render output

  



  and this is my command line for generating the output :

  



  ffmpeg -i input.mp4 -filter_complex "drawtext=fontsize=80:fontcolor=black:fontfile=himalaya.ttf:shadowx=1:shadowy=1:text='སྤྱི་སྟེགས':x=0:y=0" -c:v libx264 -b:v 400k -c:a copy output.mp4


  



  The font himalaya.ttf (Microsoft Himalaya) is the default built-in font for Tibetan on Windows 10. (See https://docs.microsoft.com/en-us/typography/font-list/microsoft-himalaya )

  



  I tried text_shaping=1 and text_shaping=0, neither one is working.

  



  I've also tried other Tibetan fonts, problem is the same.

  



  But all of those fonts are rendered correctly in other places such as web browser.

  


• Anomalie #3152 (Nouveau) : Écriture raccourcie des propriétés typos avec font

  20 janvier 2014, par b b

  Sur un site je déclare les règles css suivantes sur un élément :

  font-size : 2.62em ; font-family : dosis, sans-serif ;
  

  Si j’active le compresseur, elles sont condensée dans une déclaration font comme ceci :

  font : 2.62em dosis, sans-serif ;
  

  Cette écriture ne donne pas le même rendu car j’ai une règle plus haut dans la feuille de style qui colle l’élément en question en bold. L’utilisation de la déclaration font annule la règle en question car :

  Les propriétés pour lesquelles aucune valeur n’est spécifiée sont définies à leur valeur initiale, qui est normal pour toutes les propriétés pouvant être omises : (font-style, font-variant, font-weight et line-height).

  https://developer.mozilla.org/fr/docs/CSS/font

  Je précise que la css en question contient au moins un @media et un @font-face car Cedric me signale ceci :

  Si ta css est simple, c’est une compression simple qui est a l’oeuvre sans regroupement des regles en une seule. Mais si ta css contient des @media ou @fontface alors la compression passe par CSSTidy.

• Piwik 2.10.0 – Release Candidate

  22 décembre 2014, par Piwik Core Team — Community

  Please create a bug report in our issue tracker.

  What’s new in Piwik 2.10.0 ?

  Since our last release Piwik 2.9.1 one month ago, over 100 issues have been closed. We’ve focused on fixing bugs, improving performance, and we created a new plugin that will let you better scale Piwik to very high traffic websites using Redis.

  Much improved Log Analytics

  Log Analytics is the powerful little-known feature of Piwik that lets you import dozens of different server logs into Piwik. In Piwik 2.10.0 you can now import Netscaler logs, IIS Advanced Logging Module logs, W3C extended logs and AWS CloudFront logs. Piwik will also automatically track the username as the User ID and/or the Page Generation Time when it is found in the server logs.

  Better scalability using Redis (advanced users)

  At Piwik PRO we are working on making Piwik scale when tracking millions of requests per month. In this release we have revamped the Tracking API. By using the new QueuedTracking plugin you can now queue tracking requests in a Redis database, which lets you scale the Piwik tracking service. The plugin is included as Free/libre software in the core Piwik platform. More information in the QueuedTracking user guide.

  Better performance

  A few performance challenges have been fixed in this release.

  The Visitor Log and the Live API will render much faster on very high traffic websites. Any custom date ranges that you have selected as default in your User Settings (eg. ‘Last 7 days’ or ‘Previous 30 days’) will now be pre-processed so that your analytics dashboard will always load quickly.

  For users on shared hosting, the real time widgets could be use a lot of server resource as they are refreshed every ten seconds. We’ve improved this by only requesting data when the Browser Tab containing the Real time widgets is active.

  Other changes

  We packed in many other changes in this release such as compatibility with Mysql 5.6 and Geo location support for IPv6 addresses. A community member made Piwik compatible with Internet Explorer 9 when running in compatibility mode (which is still used in several companies).

  The Tracker algorithm has been updated : when an existing visit uses a new Campaign then it will force creating a new visit (same behavior as Google Analytics).

  If you need professional support or guidance, get in touch with Piwik PRO.

  Changelog for Piwik 2.10.0 – we plan to release Piwik 2.10.0 around 2015 Jan 5th.

  Happy Analytics, and we wish you a nice holiday season !
