i use this code for show youtube player in my website,
<iframe width="1920" height="1080" src="https://www.youtube.com/embed/ID?vq=hd1080&modestbranding=0&autoplay=1&cc_load_policy=1&fs=1&rel=0&showinfo=0&controls=2&autohide=0" frameborder="0" allowfullscreen></iframe>
I use "vq=hd1080" for play video with full-hd quality. But the quality of video when start is 720p. How can change the default quality(1080p) when video start?
Try using player.setPlaybackQuality(suggestedQuality:String):Void. This function sets the suggested video quality for the current video.
However, please note that if you set a suggestedQuality level that is not available for the video, then the quality will be set to the next lowest level that is available. For example, if you request a quality level of hd1080, and that is unavailable, then the playback quality will be set to hd720. With this, you may want to first retrieve the actual video quality of the current video using player.getPlaybackQuality():String.
And, based from this thread, you can only set the quality after the video has started playing.
