Official YouTube Blog: Updates to YouTube Live streaming
Live chat plays a key role in creating connections between creators and their community. Today we are starting to roll out chat replay to YouTube, so you can follow the conversation even after a live stream is over. Live chat replays will show up alongside the video, exactly as it appeared live.
We launched automatic captions back in 2009, and since then, we’ve auto-captioned a staggering 1 billion videos. We’re now bringing English automatic captions to live streams.
Creators can now add a location tag to their mobile live streams and video uploads and share all their favorite hot spots with viewers. You can explore other videos with the same location tag by simply clicking on it. You can also use the location filter on the search results page to find other videos from a specific spot.
