• Is it still possible to compile modern x264 with the nal long start code used prior to release r1510 ?

  25 avril 2024, par Bryan Knowles

  I'm currently nerding out on old technology with HD-DVDs. The only freely available muxer is hddvdmux, I'm using MultiAVCHD for this.
Beginning with r1510, x264 switched to short start packets for NAL HRD (from what I understand). This makes the stream incompatible with hddvdmux.
deank on doom9 patched hddvdmux to accept short start codes, but in doing so, the video file plays too quickly and the audio goes out of sync.
The results I'm getting from the 2009 release of x264 leave much to be desired in comparison to modern releases, and I'd like to get those benefits while still maintaining compatibility with the original hddvdmux.
Is it possible ? If so... Any chance someone could compile a Windows binary for me with that change ? (I think it needs to be 32 bit, but not sure)

  


  I've tried multiple options with MultiAVCHD 4.1, fell back to 4.0 but am seeing weird rainbowing effects in the color from the extremely old version if x264. I admit I haven't dived in to programming, but seemed like a single change might be a reasonable request from someone already knowledgeable.

  


• Leading Google Analytics alternative, Matomo, parodies Christopher Nolan blockbuster ahead of the UA sunset

  4 juillet 2023, par Erin — Press Releases

  Wellington, New Zealand, 4 July 2023 : In the world of online data, Google Analytics has long reigned supreme. Its dominance has been unquestioned, leaving website owners with little choice but to rely on the tech giant for their data insights. However, a new dawn in web analytics is upon us, and Matomo, the leading alternative to Google Analytics, is seizing a unique opportunity to position itself as the go-to provider. In a bold move, Matomo has launched a parody trailer, “Googleheimer,” humorously taking a satirical swipe at Google in the style of the upcoming Oppenheimer biopic by Christopher Nolan.

  Capitalising on a time-bound decision

  With an important decision looming for marketers and web specialists who need to switch analytics providers by July 1st, Matomo has found the perfect window to capture their attention.

  The urgency of the situation, combined with the high intent to switch providers, sets the stage for Matomo to establish itself as the leading alternative analytics platform of choice.

  Matomo’s parody trailer addresses the frustrations of GA4 head-on by highlighting the issues and the uncertainties caused by the sunset of Universal Analytics in humorous satire with lines such as :

  “But we’re keeping everyone’s data, right ? Right ?? …RIGHT ?!”

  Riding on the coat tails of this summer’s anticipated blockbuster from Christopher Nolan, Matomo openly points at the downsides of GA4, and reflects many frustrated marketers pain points in an entertaining way. Beneath the comedic and satirical tone lies the message that users have choices, and no longer need to surrender to the behemoth incumbent.

  Matomo was founded to challenge the status quo and provide a solution for those who believe in privacy and in ethical analytics, and who prefer that their customer data not be concentrated in the hands of just a few corporations.

  Watch the full trailer here.

  A new dawn in web analytics is upon us, and Matomo – the leading alternative to Google Analytics – is here for it. After 20 years, Google is blowing up Universal Analytics (or GA3) – and taking your data with it. Inspired by Christopher Nolan’s upcoming biopic about physicist J. Robert Oppenheimer and the making of his atomic bomb (also known as “The Manhattan Project”), this parody trailer openly points to Google and draws the comparison in humorous satire. GA4 comes with a new set of metrics, setups and reports that change how you analyse your data.

• 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
