Yes I did see that scenario previously when the stream stopped.
It seems to running good for now.
However, I came across another issue that is different than the issue I had originally. In this case the stream just would not start at all and the browser reports Streaming Failed (transcoder exited). This channel plays very old movies (and cartoons) and has an odd format. Yet I can play the stream with the NPVR executable on the server PC from the TV guide. But it fails with the web interface. Here is the log.
Ok, the stream just now stopped an I got the error message in the web browser (Chrome). While the web page with the error message was displayed the temp folder continued to fill up with chunks of video and the log file continued to grow. Task mgr showed ffmpeg.exe runnung and using about 75% CPU usage.
