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

  7 juin 2016, par ImagineDragon

  Basically I am running the following ffmpeg command to read an h264 rtsp stream using hls muxer, under Ubuntu 14.04 64bit with i7 CPU and 8GB memory :

  ffmpeg -v debug -i rtsp://172.16.11.247:554/live/ch00_0?token=hQttXvrjSPOcClQB -codec copy -flags -global_header -f hls -hls_time 5 -use_localtime 1 -hls_segment_filename '/home/eason/ffmpeg-test/%s.ts' '/home/eason/ffmpeg-test/live.m3u8'

  The 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

  I have a PHP file which executes a command :

  echo shell_exec ( 'ffmpeg -i "http://ip:8000/play/a02o" -b:v 1000k  -vb 1000k  -minrate 1000k -maxrate 1000k -aspect 16:9 -s 720x480 -vprofile main  -r 25 -threads 4  -bufsize 1500k -c:v libx264  -preset veryfast -g 60    -acodec libmp3lame -ar 44100 -ab 64k -strict experimental  -f flv "rtmp://127.0.0.1:708/live/test"  > /dev/null 2>/dev/null &  ' ) ;

  Everything is okay now, but when I restart nginx service, I’m forced to rerun the command again. Is there any way to start this command every time it is stopped ? Also, how can I know the status of the streaming, i.e., whether it is started or not ?
