    I have some problem with VideoPlayer. In editor everything looks good, but when I run application on Android device, before play video a black screen appears for a very short time

    If you are using a RenderTexture, check that the RenderTexture is clear before showing it. Otherwise, can you check if the first frame of your clip is black? If you click on your video and play the preview, you shouldn't see any black frames.

    Hi, same issue here.

    My videos don't have any black frame.
    Tried to clear the RenderTexture before Play():
    Code (CSharp):
    1. public void PlayVideo()
    2. {
    3.     ClearRenderTexture();
    4.     videoPlayer.Play();
    5. }
    6.  
    7. private void ClearRenderTexture()
    8. {
    9.     RenderTexture rt = RenderTexture.active;
    10.     RenderTexture.active = videoPlayer.targetTexture;
    11.     GL.Clear(true, true, Color.clear);
    12.     RenderTexture.active = rt;
    13. }
    Also tried clearing on Start().

    I'm thinking about doing some trick with, so maybe somehow I can load the first frame preemptively...
    Code (CSharp):
    1. videoPlayer.Play();
    2. videoPlayer.Stop();

    Don't do Play() Stop(). If you want, you can Play() Pause() instead. Maybe try another colour like red to see if it shows like expected. If you don't see any difference, perhaps there is an issue elsewhere.

    Code (CSharp):
    1. private void ClearRenderTexture()
    2. {
    3.     RenderTexture rt = RenderTexture.active;
    4.     RenderTexture.active = videoPlayer.targetTexture;
    5.     GL.Clear(true, true, Color.clear);
    6.     RenderTexture.active = rt;
    7. }
    This code should work. I would check if the targetTexture is not null and what you expect. Maybe you are not clearing the RenderTexture you are showing, but another one.
