title: Is there any way to get the live chat replay log/history for YouTube streaming video?
body: <p>I’ve been doing research on online chat message patterns recently. I’ve chosen YouTube and Twitch.tv for the chat message sources.</p>
  <p>I’ve found chat loggers for real-time livestreams, but I also need acquire the chat log/history for already broadcasted livestreams which allow live chat replay (for example, <a href="https://www.youtube.com/watch?v=1JfohG5a8y8" rel="noreferrer">https://www.youtube.com/watch?v=1JfohG5a8y8</a>).</p>
  <p>There is a tool for Twitch.tv (<a href="https://github.com/jdpurcell/RechatTool" rel="noreferrer">RechatTool from jdpurcell</a>), but I couldn’t find any similar tool for YouTube.</p>
  <p>I’ve checked <a href="https://developers.google.com/youtube/v3/live/docs/liveChatMessages/list" rel="noreferrer">YouTube API for livestream messages</a>, but I couldn’t find any instructions or tips on how to access live chat replays. Is there any possible solutions for this?</p>
