Video Player Performance is poor on Hololens

Questions & Answers
1

I am trying to play a video on 3D plane. When tried to view the video on Hololens the video fame rate is inconsistent and the audio is not proper. Using Unity Version 5.6.2f1.

Repro steps:

  1. Add Video Player to a 3D plane.
  2. Attach VideoClip to the player.
  3. Build the project and run in Hololens.

Is there any solution or fix for this issue?

  • Code:

IEnumerator playVideo()
{
videoPlayer = gameObject.AddComponent();
audioSource = gameObject.AddComponent();

    videoPlayer.playOnAwake = false;
    audioSource.playOnAwake = false;
    audioSource.Pause();

    videoPlayer.clip = VideoClipToPlay;
    videoPlayer.source = VideoSource.VideoClip;

    videoPlayer.audioOutputMode = VideoAudioOutputMode.AudioSource;

    videoPlayer.EnableAudioTrack(0, true);
    videoPlayer.SetTargetAudioSource(0, audioSource);

    videoPlayer.Prepare();

    //Wait until video is prepared
    WaitForSeconds waitTime = new WaitForSeconds(1);
    while (!videoPlayer.isPrepared)
    {
        Debug.Log("Preparing Video");
        yield return waitTime;
        break;
    }

    Debug.Log("Done Preparing Video");
   
    image.texture = videoPlayer.texture;

    //Play Video
    videoPlayer.Play();

    //Play Sound
    audioSource.Play();

    Debug.Log("Playing Video");
    while (videoPlayer.isPlaying)
    {
        Debug.LogWarning("Video Time: " + Mathf.FloorToInt((float)videoPlayer.time));
        yield return null;
    }
    Debug.Log("Done Playing Video"); 
}

I’m using almost the same algorithm and I dont have problems with video. So only thing that comes to mind is that you didn’t set Quality settings to lowest for UWP. If that doesn’t work try overwritting Quality settings on Video asset to even lower quality. Or try to use different video to see if problem is in video format or size.
I hope this helps.
