curl -X POST https://ffmpegapi.net/api/add_subtitles \
-H "Content-Type: application/json" \
-d '{"video_url":"https://example.com/video.mp4", "subtitle_url":"https://example.com/subtitles.ass", "async":false}'
import requests

url = 'https://ffmpegapi.net/api/add_subtitles'
data = {
    'video_url': 'https://example.com/video.mp4',
