[FFmpeg-user] ffmpeg stuck at "No default whitelist set"

[Felix Östh]

I'm using C# to initiate ffmpeg. I've a onvif bridge server for a CCTV VMS and I'm building a application to enable the user to livestream any CCTV camera to YouTube.

The rtsp stream to the camera looks like this:

rtsp://onvif:bridge@localhost:554/live/xxxxx-xxxguidtocameraxxx-xxxxx

I'm new to ffmpeg and I'm using this arg:

-f lavfi -i anullsrc -rtsp_transport udp -i {camerastreamurl} -tune zerolatency -vcodec libx264 -pix_fmt + -c:v copy -c:a aac -strict experimental -f flv rtmp://x.rtmp.youtube.com/live2/{streamkey} -loglevel debug

It seems like ffmpeg isn't finding the camera stream, only the fake audio one. It just freezes.

This is the result of the debug log:

I've no idea how to proceed or troubleshoot the input stream. Help?
