src/Player.tsx:15

• The variable 'Player' shadows the component name, which can be confusing. Consider renaming it to 'ActivePlayer' to clarify its purpose.

const Player = props.activePlayer;

@luwes I think this missed adding a section to MIGRATING.md noting that "Single player imports" are no longer a feature of ReactPlayer

They were originally documented in MIGRATING.md in a commit 45635ef by @cookpete :

### Single player imports

As of `v2.2`, the 🔥 __location of single player imports has changed__. Single players are not available in `v2.0` and `v2.1`.

```jsx
// Before
import ReactPlayer from 'react-player/lib/players/YouTube'

// After
import ReactPlayer from 'react-player/youtube'
```

Could this be added to the v3 migration guide section?

Another undocumented thing that was a surprise was that many parts of the config prop are very different (see README.md changes):

For example, the file.forceHls config was removed - originally added in @cookpete's commit Add support for HLS and DASH streams (c28c7ff)

Would be good to have a note in the MIGRATING.md about this, and what to do if users are missing features.

How can I set forceHLS in version 3.3.2?

[karlhorky]

I don't know - maybe @luwes can chime in here.

But I guess the option maybe is not needed anymore? (not sure what that implies about the default behavior)
