I record video streams from 3 cameras.
Stream 1:
{{{
Input #0, rtp, from 'rtp://225.1.1.1:1024':
Duration: N/A, start: 60424.501000, bitrate: N/A
Program 1
Stream #0:0: Video: h264 (High) ([27][0][0][0] / 0x001B),
yuv420p(progressiv
e), 1920x1080 [SAR 1:1 DAR 16:9], 50 fps, 50 tbr, 90k tbn, 100 tbc
Stream #0:1(eng): Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz,
mono,
fltp, 164 kb/s
}}}
Streams 2,3:
{{{
Input #0, rtsp, from 'rtsp://192.168.3.36:554/stream1':
Metadata:
title : Session streamed by "Pelco Streaming Server"
comment : stream1

fps,
25 tbr, 90k tbn, 50 tbc
}}}
I record each of them with segmentation every 1 minute using separated
ffmpeg instances like:
{{{
ffmpeg -i "rtsp://192.168.3.36:554/stream1" -vcodec copy -an -f segment
-strftime 1 -segment_time 60 "novus-%Y-%m-%d_%H-%M-%S.ts"
}}}
Every 13 hours 14 minutes (from beginning of recording) each ffmpeg stops
recording with messages like "Non-monotonous DTS in output stream 0:0":

The full debug log with this problem is here:
[https://drive.google.com/file/d/0B1LIS8G55R7-OGY4QkdkQ0J1cVE/view?usp=sharing]
I can't record video infinitely. Every 13 hours I have broken recording. I
tried to record with "-copytb 1" but it doesn't help.
Does anyone know how to solve it? I can provide you with another
information you need about this.
