• 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
