If you click the link in the errors it tells you what they mean.
- "Text content does not match server-rendered HTML."
- "Hydration failed because the initial UI does not match what was rendered on the server."
- "There was an error while hydrating. Because the error happened outside of a Suspense boundary, the entire root will switch to client rendering."
None of these should impact the videos, though, because the fallback (client-side rendering) should work too. So if that's causing the issue, it's because there's a larger problem enabling it.
