    And what about delay on Android?

    1. set url to VideoPlayer;
    2. Slow down your network connection;
    3. call VideoPlayer.Prepare() or ViedoPlayer.Play();
    4. Observe that whole game freezes until Video playback not started;

    It's still occurs!

    The problem is still prevailing guys. Please help with a solution.
    The videos seems to be working fine when played with a VideoClip hosted locally, but when a URL hosted on the cloud is played it takes forever the prepare and play.

    How is this considered acceptable to hitch the entire app every time a video needs to be prepared? Sheesh.

    I'm also getting this when trying to loop videos. I'm making an AR app that puts 1-2 second looping videos on AR targets, getting this 0.2 second delay is not helping my experience. I'm getting this on iOS but also visible on the unity editor.

    I get this delay on Android. The entire app hangs for 4 or 5 seconds. Since you can't run videoplayer.Prepare() in a background thread, I'm not sure how to work around this.

    Just an addition to my previous comment. I'm only getting significant delays on Android. On iOS the delays are much shorter and more manageable.
