通过将 PowerPoint 演示文稿转换为视频，您可以获得
* **提升可访问性：** 所有设备（无论平台）默认都配备视频播放器，相较于演示文稿打开应用，用户更容易打开或播放视频。
* **更广的覆盖面：** 通过视频，你可以触及更大的受众，并向他们传递在演示中可能显得枯燥的信息。大多数调查和统计表明，人们观看和消费视频的比例高于其他内容形式，且普遍更偏好此类内容。

## **Aspose.Slides 中的 PowerPoint 转视频转换**
Aspose.Slides 支持将演示文稿转换为视频。
* 使用 **Aspose.Slides** 生成一组帧（来自演示文稿幻灯片），对应特定的 FPS（每秒帧数）
* 使用诸如 **ffmpeg**（[for java](https://github.com/bramp/ffmpeg-cli-wrapper)）的第三方工具，根据这些帧创建视频。
### **将 PowerPoint 转换为视频**
1. 将以下内容添加到您的 POM 文件中：
```xml
net.bramp.ffmpeg
ffmpeg
0.7.0
```
2. 从[此处](https://ffmpeg.org/download.html)下载 ffmpeg。
4. 运行 PowerPoint 转视频的 Java 代码。
以下 Java 代码展示了如何将包含图形和两个动画效果的演示文稿转换为视频：
```java
Presentation presentation = new Presentation();
try {
// 添加笑脸形状并进行动画处理
IAutoShape smile = presentation.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.SmileyFace, 110, 20, 500, 500);
ISequence mainSequence = presentation.getSlides().get_Item(0).getTimeline().getMainSequence();
IEffect effectIn = mainSequence.addEffect(smile, EffectType.Fly, EffectSubtype.TopLeft, EffectTriggerType.AfterPrevious);
IEffect effectOut = mainSequence.addEffect(smile, EffectType.Fly, EffectSubtype.BottomRight, EffectTriggerType.AfterPrevious);
effectIn.getTiming().setDuration(2f);
effectOut.setPresetClassType(EffectPresetClassType.Exit);
final int fps = 33;
ArrayList frames = new ArrayList();
PresentationAnimationsGenerator animationsGenerator = new PresentationAnimationsGenerator(presentation);
try
{
PresentationPlayer player = new PresentationPlayer(animationsGenerator, fps);
try {
player.setFrameTick((sender, arguments) ->
{
try {
String frame = String.format("frame_%04d.png", sender.getFrameIndex());
arguments.getFrame().save(frame, ImageFormat.Png);
frames.add(frame);
} catch (IOException e) {
throw new RuntimeException(e);
}
});
animationsGenerator.run(presentation.getSlides());
} finally {
if (player != null) player.dispose();
}
} finally {
if (animationsGenerator != null) animationsGenerator.dispose();
}
// 配置 ffmpeg 二进制文件夹。参见此页面: https://github.com/rosenbjerg/FFMpegCore#installation
FFmpeg ffmpeg = new FFmpeg("path/to/ffmpeg");
FFprobe ffprobe = new FFprobe("path/to/ffprobe");
FFmpegBuilder builder = new FFmpegBuilder()
.addExtraArgs("-start_number", "1")
.setInput("frame_%04d.png")
.addOutput("output.avi")
.setVideoFrameRate(FFmpeg.FPS_24)
.setFormat("avi")
.done();
FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);
executor.createJob(builder).run();
} catch (IOException e) {
e.printStackTrace();
}
```
## **视频效果**
您可以对幻灯片上的对象应用动画，并在幻灯片之间使用切换效果。
{{% alert color="primary" %}}
您可能想查看以下文章：[PowerPoint Animation](https://docs.aspose.com/slides/androidjava/powerpoint-animation/)，[Shape Animation](https://docs.aspose.com/slides/androidjava/shape-animation/)，以及[Shape Effect](https://docs.aspose.com/slides/androidjava/shape-effect/)。
{{% /alert %}}
动画和切换使幻灯片放映更具吸引力和趣味性——视频亦如此。让我们在前一个演示的代码中添加另一张幻灯片和切换效果：
```java
// 添加笑脸形状并进行动画处理
// ...
// 添加新幻灯片并设置动画切换
ISlide newSlide = presentation.getSlides().addEmptySlide(presentation.getSlides().get_Item(0).getLayoutSlide());
newSlide.getBackground().setType(BackgroundType.OwnBackground);
newSlide.getBackground().getFillFormat().setFillType(FillType.Solid);
newSlide.getBackground().getFillFormat().getSolidFillColor().setColor(Color.MAGENTA);
newSlide.getSlideShowTransition().setType(TransitionType.Push);
```
Aspose.Slides 还支持文本动画。因此我们对对象上的段落进行动画，使其依次出现（延迟设为一秒）：
```java
Presentation presentation = new Presentation();
try {
// 添加文本和动画
IAutoShape autoShape = presentation.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 210, 120, 300, 300);
Paragraph para1 = new Paragraph();
para1.getPortions().add(new Portion("Aspose Slides for Java"));
Paragraph para2 = new Paragraph();
para2.getPortions().add(new Portion("convert PowerPoint Presentation with text to video"));
Paragraph para3 = new Paragraph();
para3.getPortions().add(new Portion("paragraph by paragraph"));
IParagraphCollection paragraphCollection = autoShape.getTextFrame().getParagraphs();
paragraphCollection.add(para1);
paragraphCollection.add(para2);
paragraphCollection.add(para3);
paragraphCollection.add(new Paragraph());
ISequence mainSequence = presentation.getSlides().get_Item(0).getTimeline().getMainSequence();
IEffect effect1 = mainSequence.addEffect(para1, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
IEffect effect2 = mainSequence.addEffect(para2, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
IEffect effect3 = mainSequence.addEffect(para3, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
IEffect effect4 = mainSequence.addEffect(para3, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
effect1.getTiming().setTriggerDelayTime(1f);
effect2.getTiming().setTriggerDelayTime(1f);
effect3.getTiming().setTriggerDelayTime(1f);
effect4.getTiming().setTriggerDelayTime(1f);
final int fps = 33;
ArrayList frames = new ArrayList();
PresentationAnimationsGenerator animationsGenerator = new PresentationAnimationsGenerator(presentation);
try
{
PresentationPlayer player = new PresentationPlayer(animationsGenerator, fps);
try {
player.setFrameTick((sender, arguments) ->
{
try {
String frame = String.format("frame_%04d.png", sender.getFrameIndex());
arguments.getFrame().save(frame, ImageFormat.Png);
frames.add(frame);
} catch (IOException e) {
throw new RuntimeException(e);
}
});
animationsGenerator.run(presentation.getSlides());
} finally {
if (player != null) player.dispose();
}
} finally {
if (animationsGenerator != null) animationsGenerator.dispose();
}
// 配置 ffmpeg 二进制文件夹。参见此页面: https://github.com/rosenbjerg/FFMpegCore#installation
FFmpeg ffmpeg = new FFmpeg("path/to/ffmpeg");
FFprobe ffprobe = new FFprobe("path/to/ffprobe");
FFmpegBuilder builder = new FFmpegBuilder()
.addExtraArgs("-start_number", "1")
.setInput("frame_%04d.png")
.addOutput("output.avi")
.setVideoFrameRate(FFmpeg.FPS_24)
.setFormat("avi")
.done();
FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);
executor.createJob(builder).run();
} catch (IOException e) {
e.printStackTrace();
}
```
## **视频转换类**
为了让您执行 PowerPoint 转视频的任务，Aspose.Slides 提供了 [PresentationAnimationsGenerator](https://reference.aspose.com/slides/androidjava/com.aspose.slides/presentationanimationsgenerator/) 和 [PresentationPlayer](https://reference.aspose.com/slides/androidjava/com.aspose.slides/presentationplayer/) 类。
[PresentationAnimationsGenerator](https://reference.aspose.com/slides/androidjava/com.aspose.slides/presentationanimationsgenerator/) 允许您通过构造函数设置视频（稍后将创建）的帧大小。如果传入演示文稿实例，则会使用 `Presentation.SlideSize`，并生成供 [PresentationPlayer](https://reference.aspose.com/slides/androidjava/com.aspose.slides/presentationplayer/) 使用的动画。
生成动画时，会为每个后续动画触发 `NewAnimation` 事件，该事件携带 [IPresentationAnimationPlayer](https://reference.aspose.com/slides/androidjava/com.aspose.slides/ipresentationanimationplayer/) 参数。后者是表示单独动画播放器的类。
要使用 [IPresentationAnimationPlayer](https://reference.aspose.com/slides/androidjava/com.aspose.slides/ipresentationanimationplayer/)，会使用 [Duration](https://reference.aspose.com/slides/androidjava/com.aspose.slides/ipresentationanimationplayer/#getDuration--)（动画的完整时长）属性和 [SetTimePosition](https://reference.aspose.com/slides/androidjava/com.aspose.slides/ipresentationanimationplayer/#setTimePosition-double-) 方法。每个动画位置在 *0 到 duration* 范围内设定，然后 `GetFrame` 方法将返回对应该时刻动画状态的 BufferedImage：
```java
Presentation presentation = new Presentation();
try {
// 添加笑脸形状并进行动画处理
IAutoShape smile = presentation.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.SmileyFace, 110, 20, 500, 500);
ISequence mainSequence = presentation.getSlides().get_Item(0).getTimeline().getMainSequence();
IEffect effectIn = mainSequence.addEffect(smile, EffectType.Fly, EffectSubtype.TopLeft, EffectTriggerType.AfterPrevious);
IEffect effectOut = mainSequence.addEffect(smile, EffectType.Fly, EffectSubtype.BottomRight, EffectTriggerType.AfterPrevious);
effectIn.getTiming().setDuration(2f);
effectOut.setPresetClassType(EffectPresetClassType.Exit);
PresentationAnimationsGenerator animationsGenerator = new PresentationAnimationsGenerator(presentation);
try {
animationsGenerator.setNewAnimation(animationPlayer ->
{
System.out.println(String.format("Animation total duration: %f", animationPlayer.getDuration()));
animationPlayer.setTimePosition(0); // 初始动画状态
try {
// 初始动画状态位图
animationPlayer.getFrame().save("firstFrame.png", ImageFormat.Png);
} catch (IOException e) {
throw new RuntimeException(e);
}
animationPlayer.setTimePosition(animationPlayer.getDuration()); // 动画的最终状态
try {
// 动画的最后一帧
animationPlayer.getFrame().save("lastFrame.png", ImageFormat.Png);
} catch (IOException e) {
throw new RuntimeException(e);
}
});
} finally {
if (animationsGenerator != null) animationsGenerator.dispose();
}
} finally {
if (presentation != null) presentation.dispose();
}
```
要让演示文稿中的所有动画一次性播放，使用 [PresentationPlayer](https://reference.aspose.com/slides/androidjava/com.aspose.slides/presentationplayer/) 类。该类在构造函数中接收一个 [PresentationAnimationsGenerator](https://reference.aspose.com/slides/androidjava/com.aspose.slides/presentationanimationsgenerator/) 实例和效果的 FPS，然后调用 `FrameTick` 事件以播放所有动画：
```java
Presentation presentation = new Presentation("animated.pptx");
try {
PresentationAnimationsGenerator animationsGenerator = new PresentationAnimationsGenerator(presentation);
try {
PresentationPlayer player = new PresentationPlayer(animationsGenerator, 33);
try {
player.setFrameTick((sender, arguments) ->
{
try {
arguments.getFrame().save("frame_" + sender.getFrameIndex() + ".png", ImageFormat.Png);
} catch (IOException e) {
throw new RuntimeException(e);
}
});
animationsGenerator.run(presentation.getSlides());
} finally {
if (player != null) player.dispose();
}
} finally {
if (animationsGenerator != null) animationsGenerator.dispose();
}
} finally {
if (presentation != null) presentation.dispose();
}
```
随后可以将生成的帧编译为视频。请参阅 [Convert PowerPoint to Video](https://docs.aspose.com/slides/androidjava/convert-powerpoint-to-video/#convert-powerpoint-to-video) 部分。
