• Introducing the Matomo Connector for Looker Studio (Formerly Google Data Studio)

  26 janvier 2024, par Erin — Community

  Explore Matomo data like never before with the official Matomo Connector for Looker Studio. Matomo users can now securely display accurate web analytics data in Looker Studio for free.

  Connect Matomo to Looker Studio (formerly known as Google Data Studio) in a few clicks and start building dashboards instantly. Get access to a range of data visualisation capabilities and chart types in Looker Studio’s easy-to-use interface. 

  Leave behind manual, error-prone spreadsheet entries and disparate data. With the Matomo Connector for Looker Studio, you get unified, automated reporting and interactive dashboards for faster insights and smoother collaboration.

  What sets the official Matomo Connector for Looker Studio apart ?

  Our open-source connector puts security first by providing a reliable connection without relying on third-party intermediaries. It’s free, with no hidden charges, and no limits on the number of users or Matomo instances. Connect as many instances as you need. 

  Plus, our Support team is here anytime you need help.

  

  Who is this connector made for ?

  The Matomo Connector for Looker Studio is a good fit for institutions and corporations using Looker Studio, NGOs handling multiple entities, marketing agencies with various clients, and small to medium-sized businesses with advanced data practices.

  When is this connector not the best fit ?

  If you prioritise privacy and compliance, this might not be the right fit. The Looker Studio app operates on Google servers, and while we don’t log or store any data, privacy considerations should be carefully evaluated. Transferring data, especially visitor data, to external platforms can have privacy implications.

  Getting started

  Check out our documentation for an easy setup.

  To help, we’ve also created a template report so you can visualise your Matomo data instantly.

  Here’s how to get started :

  1. Visit the demo template report in Looker Studio
  2. Click the more options button then Make a copy

  

  3. Click Create data source within the New Data Source dropdown.

  

  4. Connect your Matomo (Full Connection Guide)
  5. Select the API > Main Metrics report
  6. Click Connect and then Add to Report
  7. Click Copy Report to finalise

• Correct syntax for using ffmpeg CUDA to crop and scale videos [closed]

  9 septembre 2024, par Stuart

  My NVIDIA and FFMPEG configuration is as follows :

  I would like to be able to use CUDA to crop and scale videos but I cannot find the correct syntax.
My efforts usually work in terms of the scale but not the crop, here is an example of the type of problems I have been having :

  


  The source file in this example is a short mpeg2 video (960x540 with black bars top and bottom). The command is currently run from a bash script.

  


  ffmpeg -y -hwaccel cuda -hwaccel_output_format cuda -c:v mpeg2_cuvid -crop 960x408x0x66 -i $1 -vf scale_npp=1280x544 -c:a copy -c:v h264_nvenc -b:v 2M -preset slow $2


  


  This is throwing the following error :

  


  [mpeg2_cuvid @ 0x5e6d9deb56c0] cuvid decode callback error
[vist#0:0/mpeg2video @ 0x5e6d9de85b40] [dec:mpeg2_cuvid @ 0x5e6d9de7b7c0] Decoding error:        Generic error in an external library


  


  Have I a problem with my ffmpeg build, should the list of filters include something like crop_cuda or crop_npp or have I just got the wrong syntax to perform everything on the GPU (is it even possible).

  


• ffmpeg drawtext Arabic fonts doesn't render correctly [closed]

  11 février 2024, par Mahmoud Abdellatief

  what i'm trying to achieve :
loop an image into a video and overlay Arabic Text from the Qur'an on it including the text diacritical mark, using a custom font.

  


  example of the text to be rendered :

  


  بِسْمِ ٱللَّهِ ٱلرَّحْمَـٰنِ ٱلرَّحِيمِ


  


  the font used :
https://fonts.qurancomplex.gov.sa/wp02/wp-content/uploads/2024/01/UthmanicHafs_v22.zip

  


  font's unicode module :

  


  Unicode Module 
 
The Research and Development Unit in the Computer Department at King Fahd Glorious Qur’an Printing Complex relied on the unicode system unicode to create (Hafs) font in the Uthmanic Script, because this system is followed globally among computer and systems manufacturing companies in the world.

Unicode organization is a global code group that is used to define all codes and letters used in most of the world's languages and gathered in one code to facilitate the presentation and delivery on information despite of the language used. This global coding uses 1 to 4 bytes (byte = 8 bits) to encode letters, and so far only a third of the number available in Unicode organization to encode the letters of these languages.

Taking into account Hafs font with the Uthmanic Script, which was built entirely on the unicode system. We can explore the basic letters that were formed according to the following figure:

Whereas the font was developed starting from code (0600 ) to code (066FF ) Taking into account there are several encoded letters that haven't been used at all so it was replaces with the code []. The displayed copy above is the one that is been developed from the basic Arabic coding (0600-06FF) which was updated by Unicode organization in 2009.


  


  expected result :
exported video with correctly rendered text using the given font.

  


  actual result :
the text rendered contains only the diacritical marks ( which are the accents on top of the letters ) without the actual letters.


  


  what i tried :
this is my test command which exports just an image for faster results :

  


  Ffmpeg -loop 1  -i "image-2.jpg" -vf "drawtext=text='بِسْمِ ٱللَّهِ ٱلرَّحْمَـٰنِ ٱلرَّحِيمِ':fontsize=124:fontcolor=white:fontfile='UthmanicHafsV22.ttf':x=(w-text_w)/2:y=(h-text_h)/2" -frames:v 1  "output.png"


  


  

  • tried adding ft_load_flags , almost tried all of them

  


  • tried text_shaping=1 , with no success

  


  • tried textfile instead of text

  


  • tried changing the font, any font i try with it always have different problems, either some squares instead of the diacritical mark

  


  


  p.s im having same results on both latest ffmpeg compiled by myself on macos terminal with all required libraries enabled , and also on flutter ffmpeg kit full gpl
