VideoPlayer

描述

将视频内容播放到目标上。

Content can be either a VideoClip imported asset or a URL such as file:// or http://. Video content will be projected onto one of the supported targets, such as camera background or RenderTexture. If the video content includes transparency, this transparency will be present in the target, allowing objects behind the video target to be visible. When the data VideoPlayer.source is set to URL, the audio and video description of what is being played will only be initialized once the VideoPlayer preparation is completed. You can test this with VideoPlayer.isPrepared.

**以下部分演示了 VideoPlayer 的一些功能：**

// Examples of VideoPlayer function

using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Will attach a VideoPlayer to the main camera.
        GameObject camera = GameObject.Find("Main Camera");

        // VideoPlayer automatically targets the camera backplane when it is added
        // to a camera object, no need to change videoPlayer.targetCamera.
        var videoPlayer = camera.AddComponent<UnityEngine.Video.VideoPlayer>();

        // Play on awake defaults to true. Set it to false to avoid the url set
        // below to auto-start playback since we're in Start().
        videoPlayer.playOnAwake = false;

        // By default, VideoPlayers added to a camera will use the far plane.
        // Let's target the near plane instead.
        videoPlayer.renderMode = UnityEngine.Video.VideoRenderMode.CameraNearPlane;

        // This will cause our Scene to be visible through the video being played.
        videoPlayer.targetCameraAlpha = 0.5F;

        // Set the video to play. URL supports local absolute or relative paths.
        // Here, using absolute.
        videoPlayer.url = "/Users/graham/movie.mov";

        // Skip the first 100 frames.
        videoPlayer.frame = 100;

        // Restart from beginning when done.
        videoPlayer.isLooping = true;

        // Each time we reach the end, we slow down the playback by a factor of 10.
        videoPlayer.loopPointReached += EndReached;

        // Start playback. This means the VideoPlayer may have to prepare (reserve
        // resources, pre-load a few frames, etc.). To better control the delays
        // associated with this preparation one can use videoPlayer.Prepare() along with
        // its prepareCompleted event.
        videoPlayer.Play();
    }

    void EndReached(UnityEngine.Video.VideoPlayer vp)
    {
        vp.playbackSpeed = vp.playbackSpeed / 10.0F;
    }
}
