For standard non-360 YouTube movies, you should use a WebView layer rather than YouTube360
The YouTube 360 layer applies a number of custom Layer properties to automate the playback of a 360 YouTube movie
Settings
URL
The URL of the YouTube video.
Resolution
The width and height of the web page which renders the YouTube player. The Default setting is 7680x4320 which works for most YouTube 360 videos.
You may need to adjust this setting if you see ‘letterboxing’ during playback.
Auto Play
When enabled, the YouTube video will start playing as soon as the layer is loaded.
Auto Loop
When enabled, the YouTube video player will be set to loop
