Metode masukan gambar:
Berikut adalah tiga cara untuk menyediakan gambar. Pilih salah satu.

1. URL publik: Ideal untuk gambar yang sudah dapat diakses publik.
2. File lokal: Cocok untuk pengembangan dan pengujian lokal.
3. Enkode Base64: Terbaik untuk gambar privat atau saat data harus ditransmisikan secara aman.
"""

# [Metode 1] Gunakan URL gambar yang dapat diakses publik
# Contoh: Gunakan URL gambar publik
img_url = "https://help-static-aliyun-doc.aliyuncs.com/file-manage-files/zh-CN/20250925/wpimhv/rap.png"

# [Metode 2] Gunakan file lokal (mendukung jalur absolut dan relatif)
# Format: file:// + jalur file
# Contoh (jalur absolut):
# img_url = "file://" + "/path/to/your/img.png"    # Linux/macOS
# img_url = "file://" + "C:/path/to/your/img.png"  # Windows
# Contoh (jalur relatif):
# img_url = "file://" + "./img.png"                # Relatif terhadap direktori skrip saat ini

# [Metode 3] Gunakan gambar terenkripsi Base64
# img_url = encode_file("./img.png")

# Atur URL audio
audio_url = "https://help-static-aliyun-doc.aliyuncs.com/file-manage-files/zh-CN/20250925/ozwpvi/rap.mp3"
