  • 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 :

    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
