Merging Videos: API Endpoint Details

To merge videos, you will interact with the following endpoint:

The endpoint path is /api/merge_videos and it utilizes the POST method. You'll need to send a JSON payload containing the required video URLs and any optional parameters you wish to customize.

  • Endpoint: /api/merge_videos
  • Method: POST
  • Content Type: application/json
import requests

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

        'https://example.com/main.mp4'
    ],
    'dimensions': '1920x1080'
}

headers = {'Authorization': 'Bearer YOUR_API_KEY', 'Content-Type': 'application/json'}

response = requests.post(url, json=payload, headers=headers)
print(response.json())
