Hi, I have a problem with GStreamer application written in C++.
I developed the app which runs custom analytic plugins on multiple RTSP streams.
The application is building the pipeline using
nvvideoconvert as a group of plugins before passing the data to
nvstreammux - next, there are a few analytic plugins and output.
The configuration works fine if the app is outputting video on the screen - only for debugging purposes.
I need to run it on a server without a display. So, I ran into problems - I cut off the part of the pipeline responsible for outputting video and replaced it with a
fakesink element. Then a strange thing happened:
None of the RTSP sources was able to connect. The same sources work fine when displaying on screen.
And there are the GStremer logs about the error:

I was able to run the pipeline by changing the rtsp reading part (
rtspsrc -> decodebin to
uridecodebin), but it has a huge drawback for me - after changing the stream reading is not smooth anymore.
Could you help me, how could I run the app without display and keeping the pipeline with
