• Matomo maker InnoCraft named 2023 Hi-Tech Awards finalist

  20 avril 2023, par Erin — Press Releases

  WELLINGTON, N.Z., April 20, 2023 – InnoCraft, the makers of world-leading open-source web analytics platform Matomo, has been named an ASX Hi-Tech Emerging Company of the Year finalist in the 2023 Hi-Tech Awards. 



  Matomo founder Matthieu Aubry says, “At Matomo, we believe in empowering individuals and organizations to make informed decisions about their digital presence. By providing an open-source website analytics platform, we have created a more transparent and trustworthy digital ecosystem. We are proud to be recognised as a finalist for the Hi-Tech Awards, and we will continue to work towards a more open and ethical digital landscape, and grow the business in New Zealand and worldwide.”



  About Matomo

  Matomo, launched in 2007 as an open-source, privacy-friendly Google Analytics alternative, is trusted by over 1.5 million websites in 220 countries and has been translated in over 50 languages. Matomo tracks and analyses online visits and traffic to give users a deeper understanding of their website visitors to drive conversions and revenue ; while keeping businesses compliant with privacy laws worldwide, such as the EU’s General Data Protection Regulation (GDPR) and The California Consumer Privacy Act (CCPA).

  Aubry says Matomo is performing extremely well internationally as consumers and organizations look for privacy-focused analytics solutions, with several European countries already ruling the use of Google Analytics illegal due to data transfers to the US. In addition, Matomo’s user increase was recognized earlier this year with W3Tech’s award for the best web analytics software in its Web Technologies of the Year 2022 – with previous winners including Google Analytics and Facebook Pixel.



  A record number of companies entered the 2023 Hi-Tech Awards, with entries coming in from across the country and from all areas of the Hi-Tech sector. This depth is reflected in the line-up of finalists this year, according to David Downs, Chair of the Hi-Tech Trust, who says the standard of entries continue to grow every year.

”

  The hi-tech sector continues to flourish and it’s fantastic to see the success that so many of our companies enjoy on the international stage. This sector continues to prove its resilience and is at the forefront of our export economy in turbulent times,” says Downs.



  The Hi-Tech Awards Gala Dinner will take place on Friday, the 23rd of June, in Christchurch.

• Incomplete video when using ffmpeg to weave WAV and PNG

  18 avril 2023, par Howard Baek

  I am trying to "weave" PNG image files with a WAV file. Here is the ffmpeg command that I used :

  


  '/opt/homebrew/Cellar/ffmpeg/5.1.2_6/bin/ffmpeg' -y -f concat -safe 0 -i '/private/var/folders/bb/m2b0ry595ys7bfs1r397lnf40000gp/T/Rtmp8gnKo7/ari_input_NQIg95oycVnb.txt' -i '/private/var/folders/bb/m2b0ry595ys7bfs1r397lnf40000gp/T/Rtmp8gnKo7/ari_audio_ngNm5vr2vFta.wav' -c:v libx264 -c:a aac -ac 2    -shortest -fps_mode auto -pix_fmt yuv420p  -vf fps=5,\"scale=trunc(iw/2)*2:trunc(ih/2)*2\"   -strict experimental -max_muxing_queue_size 9999 -threads 2 '/var/folders/bb/m2b0ry595ys7bfs1r397lnf40000gp/T//Rtmp8gnKo7/file46521ffd4ef8.mp4'

  The output, a mp4 video file, isn't what I expected. I expected 6 PNG images embedded with my combined WAV file, but the video only shows 5 PNG images and a shortened WAV file.

  


  Here is the content of the txt file, ari_input_NQIg95oycVnb.txt :

  I wanted to attach my WAV file and PNG files to make this question more reproducible, but couldn't so I'll redirect you to my GitHub issue, which contains 6 separate WAV files and 6 PNG files.

  


• FFmpeg - Copy a (not A/V) data stream from input MP4 file [closed]

  31 mars 2023, par darkshine

  I've got an MP4 video file captured by DJI drone. The file contains the video stream (H.264) and also two data streams of unknown format. I would like to convert the video from h.264 to h.265 and also save both of the included data streams. Unfortunately, I cannot force FFmpeg to copy the data streams across from the input file into the output file.

  


  Here is the mp4 file :

  


  ffprobe DJI_0019.MP4

  I tried the command below :

  


  ffmpeg -i DJI_0019.MP4 -map 0 -c:v libx265 -crf 25 -c:d copy -copy_unknown DJI_0019.v2.MP4

  


  The command fails with the following error. The output file is empty.

  


  [mp4 @ 0x556d0180ced0] Could not find tag for codec none in stream #1, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
Error initializing output stream 0:0 --


  


  Note that for "-c:d" option I tried different suggested values, none of them succeeded :

  


  copy
none
bin
bin_data
data
null
file


  


  In the meantime an attempt to save the data streams to separate files succeeds for the both of them with the commands :

  


  ffmpeg -i DJI_0019.MP4 -map 0:d:0 -c copy -copy_unknown -f data DJI_0019.data0.bin

  


  ffmpeg -i DJI_0019.MP4 -map 0:d:1 -c copy -copy_unknown -f data DJI_0019.data1.bin

  


  Question :

  


  How to force FFmpeg to copy the data streams from input to output ?
