视频

这篇文章演示了如何使用 Aspose.Slides for Java 嵌入视频帧并设置播放选项。

添加视频帧

在幻灯片上插入一个空的视频帧。

static void addVideo() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        // 添加视频。
        IVideoFrame videoFrame = slide.getShapes().addVideoFrame(50, 50, 320, 240, "video.mp4");
    } finally {
        presentation.dispose();
    }
}

访问视频帧

检索添加到幻灯片的第一个视频帧。

static void accessVideo() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IVideoFrame videoFrame = slide.getShapes().addVideoFrame(50, 50, 320, 240, "video.mp4");

        // 访问幻灯片上的第一个视频帧。
        IVideoFrame firstVideo = null;
        for (IShape shape : slide.getShapes()) {
            if (shape instanceof IVideoFrame) {
                firstVideo = (IVideoFrame) shape;
                break;
            }
        }
    } finally {
        presentation.dispose();
    }
}

删除视频帧

从幻灯片中删除视频帧。

static void removeVideo() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IVideoFrame videoFrame = slide.getShapes().addVideoFrame(50, 50, 320, 240, "video.mp4");

        // 删除视频帧。
        slide.getShapes().remove(videoFrame);
    } finally {
        presentation.dispose();
    }
}

设置视频播放

配置视频，使其在显示幻灯片时自动播放。

static void setVideoPlayback() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IVideoFrame videoFrame = slide.getShapes().addVideoFrame(50, 50, 320, 240, "video.mp4");

        // 配置视频自动播放。
        videoFrame.setPlayMode(VideoPlayModePreset.Auto);
    } finally {
        presentation.dispose();
    }
}
