[FFmpeg-user] Stream relay fails after running some time

[Nick Bright]

I'm using ffmpeg to relay video streams to YouTube as an event. It's 
working, but after some time (between minutes to several hours) the 
streams will stop.

Any suggestions appreciated. Below is output and version information:

My ffmpeg command is:

ffmpeg -reorder_queue_size 120 -i $SOURCE -f lavfi -i anullsrc -c:v copy 
-c:a aac -f flv $YOUTUBE_URL/$KEY
