How to Use the Add Subtitles API

To use the Add Subtitles API, you'll need to send a POST request to the /api/add_subtitles endpoint. This endpoint requires both a video URL and an ASS/SSA subtitle file URL to process the request effectively.

The API can handle requests synchronously or asynchronously, allowing you to choose the best method for your application's needs.

  • Endpoint: POST /api/add_subtitles
  • Parameters include video_url and subtitle_url.
  • Optionally, set async to true for background processing.
curl -X POST https://www.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": true}'

url = 'https://www.ffmpegapi.net/api/add_subtitles'
