You can see in the same topic that the reconnecting functionality failed for 6 public RTSP streams (each of 15 framerate) and also for 2 local RTSP streams (of 20 and 25 framerate). I have shared the logs.
Have you tried testing with more than 2 RTSP streams? And with streams having different framerate? And also left the streams processing in the pipeline for at least 24 hours?
