• CVAT error during installation of development version

  28 novembre 2022, par Raman

  I'm trying to install development version of CVAT according to official instruction but struggling at the step of requirements.txt applying :

  


  pip install -r cvat/requirements/development.txt


  


  ... with following error :

  I have already tried suggested fixes, but no luck :
https://github.com/openvinotoolkit/cvat/issues/4406

  


  Environment :

  


  

  • MacBook Pro (Intel x64)

  


  • macOS Monterey (Version 12.4)

  


  • (pyenv) Python 3.9.10

  


  


  What other options could be applied to fix it ?

  


• Embed custom meta-data (bounding boxes) into HLS video stream

  8 mai 2024, par Alexender Iotko

  I'd like to embed bounding boxes, labels, etc. into live video stream to optionally draw them thereafter on the client-side in web-browser and looking for a way how to do.

  


  Could you please give me a hint how to insert the meta-data "on fly" and which player might be used for it ?
