Hello

I want to render a mp4 file, but unfortunately the rendering aborts with the following message

Rendern von /home/damian/kdenlive/Unbenannt.mp4 abgestürzt
Using network protocols without global network initialization. Please use avformat_network_init(), this will become mandatory later.

Failed to load "/tmp/kde-xxxx/kdenliveT12839.mlt"

Does anybody have any idea.

Thank you very much for your help.
