Camera streaming and requesting a snapshot at the same time not possible


I have a dafang camera.


  • platform: generic
    name: dafang_1
    stream_source: !secret dafang_1_stream_url
    still_image_url: !secret dafang_1_picture_url
    verify_ssl: false
    authentication: digest

When I open the stream on the UI and request a snapshot at the same time my system crashes and I need to power cycle it. No error is given because of the crash.

Is it simple not possible to do this two things at the same time or why does my system crash?
