python如何结合ai生成带音频解说的流程图ppt演示视频？

步骤：

1. 提取PPT中的文本和图片2. 使用Google Text-to-Speech生成语音3. 为每页PPT创建视频片段4. 自动排版图片和文字5. 合成最终视频

参考代码：

from pptx import Presentation
from moviepy.editor import ImageClip, TextClip, CompositeVideoClip, concatenate_videoclips, AudioFileClip
from gtts import gTTS
import os
import tempfile
import shutil

class PPTVideoGenerator:
    def __init__(self, 
                 ppt_path: str,
                 output_path: str,
                 slide_duration: float = 5.0,
                 language: str = 'zh-cn',
                 size: tuple = (1920, 1080)):
        """

        Args:

            output_path: 输出视频路径
            slide_duration: 每页PPT的默认时长(秒)
            language: 文字转语音的语言
            size: 视频尺寸
        """
        self.ppt_path = ppt_path
        self.output_path = output_path
        self.slide_duration = slide_duration
        self.language = language
        self.size = size
        self.temp_dir = tempfile.mkdtemp()
        
    def extract_slide_content(self, slide):

        texts = []
        images = []

        for shape in slide.shapes:

                if shape.text.strip():
                    texts.append(shape.text.strip())

            if shape.shape_type == 13:  # MSO_SHAPE_TYPE.PICTURE
                image_path = os.path.join(self.temp_dir, f"image_{len(images)}.png")
                with open(image_path, 'wb') as f:
                    f.write(shape.image.blob)
                images.append(image_path)
                
        return texts, images
