对每个人而言，真正的职责只有一个：找到自我。然后在心中坚守其一生，全心全意，永不停息。所有其它的路都是不完整的，是人的逃避方式，是对大众理想的懦弱回归，是随波逐流，是对内心的恐惧 ——赫尔曼·黑塞《德米安》
Demo简单介绍
Wav2Lip-GAN
Wav2Lip-GAN 是一种基于生成对抗网络（GAN）的语音到唇形的转换模型。https://github.com/Rudrabha/Wav2Lip
基本原理是使用语音信号和人脸图像来训练一个生成器网络，该网络可以将输入的语音信号转换为对应的唇形。
该模型包括两个子网络：
- 一个是语音识别网络，用于将语音信号转换为文本；
- 另一个是唇形生成网络，用于将文本和人脸图像作为输入，生成对应的唇形。
两个网络通过GAN框架进行训练，以使生成的唇形尽可能地逼真。在测试阶段，给定一个语音信号和一个人脸图像，该模型可以生成一个与语音信号相对应的唇形序列，从而实现语音到唇形的转换。
GFPGAN
腾讯 GFPGAN 是一种基于生成对抗网络（GAN）的图像超分辨率模型。https://github.com/TencentARC/GFPGAN
基本原理是使用低分辨率的图像作为输入，通过生成器网络将其转换为高分辨率的图像。
该模型包括两个子网络：
- 一个是生成器网络，用于将低分辨率图像转换为高分辨率图像；
- 另一个是判别器网络，用于评估生成的图像是否逼真。
两个网络通过GAN框架进行训练，以使生成的图像尽可能地接近真实图像。在测试阶段，给定一个低分辨率的图像，该模型可以生成一个与之对应的高分辨率图像。腾讯GFPGAN采用了一些创新的技术，如渐进式训练、自适应实例归一化等，使得其在图像超分辨率任务中表现出色。

环境安装
wav2lip 环境
当前系统环境为 window11,Anaconda3 使用CPU 跑，虚拟环境创建
C:\Users\liruilong>conda create -n wav2lip python=3.8
C:\Users\liruilong>conda info --envs
# conda environments:
#
base * C:\ProgramData\Anaconda3
myenv C:\Users\liruilong\AppData\Local\conda\conda\envs\myenv
wav2lip C:\Users\liruilong\AppData\Local\conda\conda\envs\wav2lip
切换虚拟环境的时候，报错了
C:\Users\liruilong>conda activate wav2lip
.....
后来在Anaconda Prompt (Anaconda3) 可以正常执行
(base) C:\Users\山河已无恙\Documents\GitHub\Wav2Lip-GFPGAN>conda activate wav2lip
(wav2lip) C:\Users\山河已无恙\Documents\GitHub\Wav2Lip-GFPGAN>conda list

安装 requirements.txt 中的依赖库，直接安装报错了

运行完会在当前目录生成 result.mp4 文件
https://www.bilibili.com/video/BV1fX4y187jW/
然后用模型wav2lip_gan.pth 在试下
(wav2lip) C:\Users\山河已无恙\Documents\GitHub\Wav2Lip-GFPGAN>python .\Wav2Lip-master\inference.py --checkpoint_path .\inputs\wav2lip_gan.pth --face .\inputs\kim_7s_raw.mp4 --audio .\inputs\kim_audio.mp3 --outfile result.mp4

需要把上面生成的文件移到这个文件夹里面，然后执行下面的脚本
# day1.py
wav2lipFolderName = 'Wav2Lip-master'
gfpganFolderName = 'GFPGAN-master'
wav2lipPath = '.\\' + wav2lipFolderName
gfpganPath = '.\\' + gfpganFolderName
outputPath = ".\\results"
import cv2
from tqdm import tqdm
from os import path
import os
# 上一步生成的视频
inputVideoPath = outputPath+'\\result.mp4'
# 中间数据
unProcessedFramesFolderPath = outputPath+'\\frames'
if not os.path.exists(unProcessedFramesFolderPath):
os.makedirs(unProcessedFramesFolderPath)
vidcap = cv2.VideoCapture(inputVideoPath)
numberOfFrames = int(vidcap.get(cv2.CAP_PROP_FRAME_COUNT))
fps = vidcap.get(cv2.CAP_PROP_FPS)
print("FPS: ", fps, "Frames: ", numberOfFrames)
for frameNumber in tqdm(range(numberOfFrames)):
_,image = vidcap.read()
cv2.imwrite(path.join(unProcessedFramesFolderPath, str(frameNumber).zfill(4)+'.jpg'), image)
print("unProcessedFramesFolderPath:",unProcessedFramesFolderPath)
print("inputVideoPath:",inputVideoPath)
作用是将wav2lip处理的视频按帧数逐帧读取，将每一帧保存为 JPEG 格式的图片，并将这些图片保存到指定的文件夹 unProcessedFramesFolderPath 中
