Fix VideoPlayer

[theapache64]

Changes

This PR fixes two issues with the VideoPlayer sample.

🐛 No Video

Problem:

• Previously, we were using vlcj's EmbeddedMediaPlayerComponent to play the video. This component doesn't work on macOS due to insufficient support from the AWT side. [1][2]. This caused the player not to play the video on macOS.

Solution:

• Check the OS type and provide EmbeddedMediaPlayerComponent or CallbackMediaPlayerComponent(for macOS) accordingly. (here's the commit 1e396c7)

🐛 Local file path Issue

Problem:
Previously, the URL was a local file path that wouldn't exist in every system.

Solution:
Update it to a public URL. Here's the commit (4366a6e)

Output

player.mp4

[igordmn]

Found issues:

1. Fullscreen is too slow on macOs on my machine (MacBook Pro 2019 16" i9), but not slow on the theapache64 machine.
2. I noticed a frame tearing (as happened when vsync is disabled)
3. Encountered:

 java.io.IOException: Native library (darwin/libvlc.dylib) not found in resource path

until I installed VLC:

brew install vlc

I think we need to bundle VLC as a part of VideoPlayer.

@igordmn I am using the same MBP, but with a dual monitor setup. I was running the demo on the external monitor. Moving the output window to MBC's display also causing the same issue.
