VideoPlayer

描述

将视频内容播放到目标上。

内容可以是导入的 VideoClip 资源或 URL，例如 file:// 或 http://。视频内容将投射到受支持的目标之一，例如摄像机背景或 RenderTexture。如果视频内容包含透明度，则此透明度将存在于目标中，允许视频目标后面的对象可见。当数据 VideoPlayer.source 设置为 URL 时，播放内容的音频和视频描述仅在 VideoPlayer 准备完成后初始化。您可以使用 VideoPlayer.isPrepared 测试这一点。

有关支持的视频文件格式的更多信息，请参阅 视频文件兼容性。

以下演示了 VideoPlayer 的一些功能

// Examples of VideoPlayer function

using UnityEngine;
using UnityEngine.Video;

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;
    }
}
