## Batch-Verarbeitung

```python
import os
import subprocess

def batch_wav2lip(faces_dir, audio_path, output_dir):
    os.makedirs(output_dir, exist_ok=True)

    for filename in os.listdir(faces_dir):
        if filename.endswith(('.mp4', '.jpg', '.png')):
            face_path = os.path.join(faces_dir, filename)
            output_path = os.path.join(output_dir, f"synced_{filename}")

            if filename.endswith(('.jpg', '.png')):
                output_path = output_path.rsplit('.', 1)[0] + '.mp4'

            cmd = [
                "python", "inference.py",
                "--checkpoint_path", "checkpoints/wav2lip_gan.pth",
                "--face", face_path,
                "--audio", audio_path,
                "--outfile", output_path
            ]

            try:
                subprocess.run(cmd, check=True)
                print(f"Processed: {filename}")
            except subprocess.CalledProcessError as e:
                print(f"Error processing {filename}: {e}")

# Verwendung
batch_wav2lip("./faces", "speech.wav", "./outputs")
```

## Gradio-Oberfläche

```python
import gradio as gr
import subprocess
import tempfile
import os

def lip_sync(face_video, audio, quality):
    checkpoint = "checkpoints/wav2lip_gan.pth" if quality == "High (GAN)" else "checkpoints/wav2lip.pth"

    with tempfile.NamedTemporaryFile(suffix=".mp4", delete=False) as out_file:
        output_path = out_file.name

    cmd = [
        "python", "inference.py",
        "--checkpoint_path", checkpoint,
        "--face", face_video,
        "--audio", audio,
        "--outfile", output_path
    ]

    subprocess.run(cmd, check=True)
    return output_path

demo = gr.Interface(
    fn=lip_sync,
    inputs=[
        gr.Video(label="Face Video/Image"),
        gr.Audio(type="filepath", label="Audio"),
        gr.Radio(["Standard", "High (GAN)"], value="High (GAN)", label="Quality")
    ],
    outputs=gr.Video(label="Lip-Synced Video"),
    title="Wav2Lip - Lip Sync"
)

demo.launch(server_name="0.0.0.0", server_port=7860)
```

## API-Server

```python
from fastapi import FastAPI, UploadFile, File
from fastapi.responses import FileResponse
import tempfile
import subprocess
import os

app = FastAPI()

@app.post("/sync")
async def sync_lips(
    face: UploadFile = File(...),
    audio: UploadFile = File(...),
    quality: str = "gan"
):
    with tempfile.TemporaryDirectory() as tmpdir:
        # Uploads speichern
        face_ext = os.path.splitext(face.filename)[1]
        face_path = os.path.join(tmpdir, f"face{face_ext}")
        audio_path = os.path.join(tmpdir, "audio.wav")
        output_path = os.path.join(tmpdir, "output.mp4")

        with open(face_path, "wb") as f:
            f.write(await face.read())
        with open(audio_path, "wb") as f:
            f.write(await audio.read())

        # Run Wav2Lip
        checkpoint = "checkpoints/wav2lip_gan.pth" if quality == "gan" else "checkpoints/wav2lip.pth"

        cmd = [
            "python", "inference.py",
            "--checkpoint_path", checkpoint,
            "--face", face_path,
            "--audio", audio_path,
            "--outfile", output_path
        ]

        subprocess.run(cmd, check=True)

        return FileResponse(output_path, media_type="video/mp4")

# Ausführen: uvicorn server:app --host 0.0.0.0 --port 8000
```

## TTS + Wav2Lip-Pipeline

Komplett von Text zu Video:

```python
from TTS.api import TTS
import subprocess

def text_to_lipsync(text, face_path, output_path, language="en"):
    # Sprache generieren
    tts = TTS("tts_models/multilingual/multi-dataset/xtts_v2")
    audio_path = "temp_speech.wav"
    tts.tts_to_file(text=text, file_path=audio_path, language=language)

    # Lippen-Synchronisation
    cmd = [
        "python", "inference.py",
        "--checkpoint_path", "checkpoints/wav2lip_gan.pth",
        "--face", face_path,
        "--audio", audio_path,
        "--outfile", output_path
    ]
    subprocess.run(cmd, check=True)

    return output_path

# Verwendung
text_to_lipsync(
    "Hello, welcome to our presentation.",
    "presenter.jpg",
    "talking_presenter.mp4"
)
```

## Nachbearbeitung

### Ergebnis hochskalieren

```python
import subprocess

def upscale_video(input_path, output_path):
    cmd = [
        "python", "-m", "realesrgan",
        "--input", input_path,
        "--output", output_path,
        "--scale", "2"
    ]
    subprocess.run(cmd, check=True)
```

### Audio wieder hinzufügen

```bash

# Falls Audio verloren ging, wieder hinzufügen
ffmpeg -i synced_video.mp4 -i original_audio.wav \
    -c:v copy -c:a aac \
    -map 0:v:0 -map 1:a:0 \
    final_output.mp4
```

## Fehlerbehebung

### Gesicht nicht erkannt

* Stelle sicher, dass das Gesicht deutlich sichtbar ist
* Gute Beleuchtung
* Frontal bevorzugt
* Höhere Auflösung der Eingabe

### Schlechte Synchronisationsqualität

* Verwende wav2lip\_gan.pth
* Passe Padding an
* Überprüfe die Audioabtastrate (16 kHz empfohlen)

### Ruckelige Ausgabe

* Erhöhe resize\_factor
* Deaktiviere nosmooth
* Verwende hochwertigeres Eingabevideo
