• Where to place the fontfile for the FFmpeg drawtext-Filter ?

  18 juin 2018, par jpGerhard

  I’m using the precompiled FFmpeg-Android by Bravobit (via gradle : implementation 'nl.bravobit:android-ffmpeg:1.1.5' ; based on WritingMind’s) with the intention of drawing the current timestamp/location onto a .mp4 file. I am completely new to FFmpeg and have started with Android Studio a few months ago.

  Information :

  • IDE : Android Studio
  • OS : OSX 10.13.5

  My problem :

  I don’t know whether the fontfile needs to be in the Application path on my Phone, in the Android Studio directory or just on a location on my MacBook (so it gets compiled when running the application).

  Basic FFmpeg commands (-version, ...) are working, but I can’t seem to figure out where I have to place my fontfile.

  My current command is as follows :

  -i /path/to/video.mp4 -vf drawtext=fontfile=/users/shared/fonts/arial.ttf:text='Hello World' /path/to/output.mp4

  I’ve tried a lot of variations and always received to following errors :

  Fontconfig error : Cannot load default config file
  [Parsed_drawtext_0 @ 0xecbfd420] impossible to init fontconfig
  [AVFilterGraph @ 0xec9cc140] Error initializing filter ’drawtext’ with args ’fontfile=/users/shared/fonts/arial.ttf:text=Hello World’
  Error reinitializing filters !
  Failed to inject frame into filter network : Unknown error occurred
  Error while processing the decoded data for stream #0:0
  Conversion failed !

  Does anyone have a suggestion on how to get this to work ?

• Developers and vendors : Want a Matomo Hoodie ? Add a tag to the Matomo Open Source Tag Manager and this could be yours !

  7 juin 2018, par Matomo Core Team — Community, Development

  The Free Open Source Tag Manager is now available as a public beta on the Matomo Marketplace. Don’t know what a Tag Manager is ? Learn more here. In Short : It lets you easily manage all your third party JavaScript and HTML snippets (analytics, ads, social media, remarketing, affiliates, etc) through a single interface.

  Over the last few months we have worked on building the core for the Matomo Tag Manager which comes with a great set of features and a large set of pre-configured triggers and variables. However, we currently lack tags.

  This is where we need your help ! Together we can build a complete and industry leading open source tag manager.

  Tag examples include Google AdWords Conversion Tracking, Facebook Buttons, Facebook Pixels, Twitter Universal Website Tags, LinkedIn Insights.

  Are you a developer who is familiar with JavaScript and keen on adding a tag ? Or are you a vendor ? Don’t be shy, we appreciate any tags, even analytics related :) We have documented how to develop a new tag here, which is quite easy and straightforward. You may also need to understand a tiny bit of PHP but you’ll likely be fine even if you don’t (here is an example PHP file and the related JS file).

  As we want to ship the Matomo Tag Manager with as many tags as possible out of the box, we appreciate any new tag additions as a pull request on https://github.com/matomo-org/tag-manager.

  We will send out “Matomo Contributor” stickers that cannot be purchased anywhere for every contributor who contributes a tag within the next 3 months. As for the top 3 contributors… you’ll receive a Matomo hoodie ! Simply send us an email at hello@matomo.org after your tag has been merged. If needed, a draw will decide who gets the hoodies.

  FYI : The Matomo Tag Manager is already prepared to be handled in different contexts and we may possibly generate containers for Android and iOS. If you are keen on building the official Matomo SDKs for any of these mobile platforms, please get in touch.
