• Is there any open source solution to display a remote stream inside a Hololens2 UWP Vuforia application ?

  19 avril 2023, par T777

  What do we need ?

  


  We are trying to develop an application for quality management in which we show an hologram on a metal part as an assitance marking. (using Hololen2 + Vuforia + ModleTargets) The employee uses an sensor to follow this assitance marking and the data will be analyzed live by a test device. The results are outputed on a screen / are visible at an closed source application of the manufacturer of the test device.

  


  Capturing of the video output :
The current plan is to capture the video stream of the test device via capture card. Add a via mrtk2 videopanel inside the vuforia app and stream the captured video to the Hololens2 using obs or an OpenCV python script for screen recording.

  


  What we have tried so far

  


  1) Sending Raw udp stream
via RMTP and decoding + converting with gstreamer server and writing an own library in Unity for Receiving
Result : Temporary stopped, because receiving the udp streams needs connection/ session management (signalling) frame syncing and agreement on video size, color format, frame rate etc.. and we have no solution.
An own implementation of any of this would have high complexity is consuming a lot of time.

  


  2) Using available protocols that i can find on the web
Actually there are some protocols already developed for session creation and streaming :

  


  

  • HTTP streaming (HLS) (Transport + Session)

  


  • RTMP (Transport + Session),

  


  • RTP (Transport) + RTPS (Session),

  


  • WebRTC : Is possible with different protocol stacks
RTMP/TCP/UDP (Transport) + SDP (standardized format for video paramaters) + ICE (p2p)/ WHIP (http, client-server) / Websocket(client-server) (signaling protocols) that can be used and some good open source streaming servers (gstreamer, mediamtx and srs)

  


  


  When using these the video will be encoded typcially with xh264 and need to be decoded on the HoloLens 2. There are APIs to C/C++ native (hardware) decoding libraries like unity-vlc and ffmpeg.NET that needing media library ffmpeg. I could figure out (not tested) that there is an hardware h264 decoder on the HoloLens2 but I have no clue how to access it. Since there I couldnt disvocer any information about HoloLens2 media libraries.

  


  3) Using Unity packages

  


  


  • Unit package WebRTC (https://docs.unity3d.com/Packages/com.unity.webrtc@2.4/manual/index.html) supports multiple transport protocols seem to have no signaling mechanism and

    


  


  • Unity package Render streaming (https://docs.unity3d.com/Packages/com.unity.renderstreaming@3.1/manual/index.html) is a fully integrated unity to unity and unit to browser streaming package with integrated stream Server with web GUI. It offers various streaming protocols (TCP, UDP,rmtp) and signaling mechanism over websocket, http (seems custom and not whip) or Furiouus.
BUT it doesnt support UWP as noted into the documentation. Implementing an example application we could demonstrate an working example with Vuforia, but it fails on build with target UWP on missing libraries.

  Will be testing other compile options tomorrow..

  


  

  • Mixed Reality WebRTC (https://github.com/microsoft/MixedReality-WebRTC) :
Various protocol support, Microsoft brought Webrtc specifically to HoloLens.
Deprecated, as fas as I can see just support for Hololens1 and ARM32. So i can not evaluate if trying it with this is worth it.

  


  


  What are the next options ?

  


  

  • Developing a raw udp streaming library with untiy directly.

  


  • Rebuilding the application with visionlib (ARM32) compatible and MixedRealityWebRTC (ARM32)

  


  • Porting ffmpeg + API to UWP ?

  


  • Also there seem some affords to make WebRTC in general available to UWP platforms : https://github.com/microsoft/winrtc

  


  


  The questions

  


  

  • Does Vuforia support ARM32 ?

  


  • How to access hardware decoder of Hololens2 via Unity Code ?

  


  


• Unwrapping Matomo 5.2.0 – Bringing you enhanced security and performance

  25 décembre 2024, par Daniel Crough — Latest Releases

   As we tie a bow on 2024, we’re delighted to share our final gift of the year. Matomo 5.2.0 comes wrapped with new security features, privacy controls, and performance improvements to enhance your analytics experience.

   Enhanced security and privacy controls

  

  We’ve strengthened Matomo’s security framework with several key updates :

  • A new installer timestamp mechanism for on-premise installations creates a secure 72-hour installation window, preventing unauthorised access during setup
  • Enhanced account security features including a “This Wasn’t Me” link in password reset emails and location-based login alerts
  • The new Global List of Query URL parameters feature lets you refine tracking by excluding sensitive or unnecessary parameters from collection

  Tag manager improvements for better efficiency

  

  The Matomo Tag Manager now includes several features to streamline your workflow :

  • New Consent Management Platform (CMP) tags for CookieYes, OneTrust, and Axeptio, simplifying consent tracking implementatio.
  • A new copy feature for containers, tags, and triggers that reduces setup time and ensures consistency across multiple properties
  • Improved management tools for maintaining standardised tracking across websites

  Performance and reliability updates

  We’ve made technical improvements to enhance Matomo’s performance :

  • Full PHP 8.4 compatibility for improved performance and reliability
  • Optimised archiving processes including smarter handling of recent data
  • New recovery options for interrupted archiving processes
  • Specific improvements for TiDB compatibility, enhancing database performance for users of this engine

  Important to note : This release does not require any major database upgrade, making it easier to implement these improvements.

  Looking forward to 2025

  As we prepare to enter a new year, these updates reflect our ongoing commitment to providing privacy-focused analytics. We’re grateful to all our community contributors who have helped make this release possible. Special thanks to the Matomo community for their contributions to this release.

  Ready to explore these new features ? Update to Matomo 5.2.0 today and start the new year with enhanced security, efficiency, and control over your analytics data.

  From all of us at Matomo, thank you for being part of our journey. Here’s to another year of protecting privacy and empowering insights together !
