I have 4 noname ip-cams and have troubles with capturing rtsp streams. Randomly output file not even created. I'm capturing stream via ffmpeg. Tried on Ubuntu Server 18.04 with snap ffmpeg and Debian 7 with ordinary ffmpeg. The same touble.

(/snap/bin/ffmpeg -y -use_wallclock_as_timestamps 1 -hide_banner -loglevel trace -i rtsp://192.168.0.16$1:554/11 -c:v copy -an -flags +global_header $VIDEO_FILE  2> $LOG_FOLDER/cam$1 ) &

Tried -loglevel debug but it show only successful RTSP connection and that's all. With -loglevel trace I have noticed difference between successful and failed process.

Looks like a sh*t.
Log files aren't full, but I think it's enough. That appears randomly with random cams.
How to fix it?

I've found solution myself. I've got that problem was with packet authenticity. I've tried to add forced tcp connection flag (-rtsp_transport tcp) and it works. No problem anymore.
