I downloaded the latest version for CentOS 7 from the ffmpeg website after your first e-mail and my two previous posts were based on that. As for the download using an old version of youtube-dl that is in the past and not something I can do again since it was a live event. I was hoping that knowing the output from youtube-dl when recording would allow us to know which options to use to force ffmpeg to play it back - assuming it can be done, of course. Output from various other packages follow below.
