[FFmpeg-user] Any way to get ffmpeg to show the encoding delay from input -> output

I'm trying to figure out how to solve an issue I have. I bring in live multicast streams into ffmpeg then hardware transcodes to 1-N output multicast streams. Normally the lag from input->output is a few seconds. Sometimes though, I've seen streams that are like 10-30 minutes behind the input stream (I'm not sure what causes this either, but I have a capture of a stream that gets off quickly). I would like to know if there is a way to get ffmpeg to show me the delay from an input stream to an output stream. If I can get that I can detect its way off and restart ffmpeg. Thanks
