1080p video quality is not available

[gzalinski]

I found that in the parameters exist 1080p, but it is not returned.

Some videos on YouTube do not have 1080p streams, however, they might have 1080pna.

You can add a list of supported formats in order of priority like so:

new YouTubeToHtml5({
  formats: [ '1080pna', '1080p' ]
});

Please note that a new release has been published.

Hope this helps.
