LibreElec + VDR : How to edit the records ?

Hello,

I want to know how to edit/cut the records done with the backend VDR under Kodi, even I use LibbreElec on  a RaspberryPi 3.

With VDR, when you are watching a video, you could edit it with the followings keys :

• 0 (zero) to set a mark
  
• 4, 6 to move backward and forward the mark
  
• 7, 9 to move at the previous and next mark
  
• 2 to launch the edit/cutting operation
  

My configuration :

• LibreElec with a RaspberryPi 3 : https://libreelec.tv/downloads_new/raspberry-pi-3-3/, version 9.2.1
  
• DVB Tuner : Sundtek MediaPro III (the remote command is not working correctly), used in DVB-T mode
  
• VDR Backend
  
• VDR VNSI client
  
• country : France
  
• classic USB Azery keyboard to control Kodi (for the moment)
  

I've tried the 'live' plugin for VDR but I can't see the image of my TV channel. It's only possible if I use VLC.

What's the solution to edit/cut the records done by VDR under Kodi ?

Thank for your replies and help.

Best regards.
