ffmpeg stops randomly with "No more output streams to write to, finishing" when reading rtsp stream [on hold]

0 frames successfully decoded, 0 decoding errorsThe problem is that ffmpeg exits randomly after 5 to 20 minutes. The RTSP is a live stream so stopping every 5 minute is really not acceptable. In the ffmpeg log I can’t see any noticeable error except "No more output streams to write to, finishing." near the end. Can someone shed some light upon this ? How can I make ffmpeg run without stopping ? Thanks

Frame loss while FFmpeg video splitting
27 mai 2016, par Gurinderbeer SinghI am using ffmpeg to split the video file into multiple parts by following command. But there is frame loss.
ffmpeg -i input.mp4 -ss 00:00:00 -t 00:10:00 -c copy output.mp4For example there are total 17983 frames in complete video file. But total number of frames combined in all the splitted parts is 17970. So there are 13 frames less.
Can anyone please tell, if there is any method by which we can split the video without any frame loss. Even by using some other tool than ffmpeg.
Thanks....
