• Calculate PSNR and MSE for individual frames using ffmpeg

  26 juin 2015, par Mayank Agarwal

  I have an avi file.i am converting avi file to .mp4 codec H.264 and ain second case to .mp4 file codec H.265.Now i want to calculate the PSNR/MSE/MSAD between the ref file(avi file) and the converted mp4 file using ffmpeg.Came across ffmpeg command line filters for PSNR and SSIM calculation but it gives the average PSNR value not the PSNR value frame by frame.Also i want to do it using code and not using command line.Read several examples in demuxing.c it is separating the whole file into frames in av_read_frame before calling decode
  but how can i convert pkt to frame and able to calculate PSNR or MSE values.

  Regards

• Enhanced Privacy Control : Matomo’s Guide for Consent Manager Platform Integrations

  13 février, par Alex Carmona — Development, Latest Releases

  In today’s digital landscape, protecting user privacy isn’t just about compliance—it’s about building trust and demonstrating respect for user choices. Even though you can use Matomo without requiring consent when properly configured in compliance with privacy regulations, we’re excited to introduce a new Consent Manager Platforms (CMP) category on our Integrations page to make it easier than ever to implement privacy-respecting analytics.

  What’s a consent manager platform ?

  A Consent Management Platform (CMP) is a tool that helps websites collect, manage, and store user consent for data tracking and cookies in compliance with privacy regulations like GDPR and CCPA. A CMP allows users to choose which types of data they want to share, ensuring transparency and respecting their privacy preferences. By integrating a CMP with Matomo, organisations can make sure that analytics tracking occurs only after obtaining explicit user consent.

  

  Remember, you can configure Matomo to remain fully GDPR compliant, without requiring user consent.

  Why consent management matters

  With privacy regulations reshaping data collection practices daily, organisations need to ensure that analytics data is gathered only after users have explicitly given their consent. Integrating Matomo with a Consent Management Platform helps you :

  • Strengthen regulatory compliance
  • Enhance user trust through transparency
  • Clearly document consent choices
  • Simplify privacy management

  By making consent management seamless, you can maintain compliance while delivering a privacy-first experience to your users.

  Introducing our CMP integration options

  We’ve carefully curated integrations with leading Consent Management Platforms that work seamlessly with Matomo Analytics and Matomo Tag Manager. Our supported platforms include :

• Automatically inject 360° 3D metadata into a video with a Bash script

  27 octobre 2019, par Eduardo Perez

  So, I have a Cygwin script I made which concats several videos into a single video with different variations, and I want to inject stereoscopic 3D metadata into the videos through the script so I don’t have to inject each video separately using Google’s injector tool. The videos are all 360° videos with top/bottom 3D and standard stereo audio rather than spacial audio, and in an MP4 container. Is there any way that I can either inject the needed 3D metadata using FFmpeg so I can upload it to YouTube as a 360VR video, or use the source code of Google’s injector tool or some other tool in order to inject the metadata the same way that Google’s injector tool would so it’s supported as a 360° 3D video by YouTube ?

  Also, will the injector tool automatically move the MOV atom to the beginning of the file (if the injector tool is used) or will I still need to use -movflags +faststart in FFmpeg ? The videos are kind of big and apparently using FFmpeg to concat several video files together and copy the stream codecs with -movflags +faststart and then injecting the metadata using Google’s Spherical Media tool is three times longer than just using FFmpeg in the same way but without -movflags +faststart, so if there was a fast way to do this I’d greatly appreciate it.
