Automating Video Editing with FFMPEGAPI.net: Merge Images and Audio Seamlessly

Understanding the /api/merge_image_audio Endpoint

The /api/merge_image_audio endpoint allows developers to combine images and audio files into a single MP4 video. By utilizing this feature, you can display each image for the duration of its corresponding audio track. This is particularly useful for creating presentations, tutorials, or engaging content for social media.

With FFMPEGAPI.net, you don’t need to manage any FFmpeg infrastructure. Just focus on your application while we handle the heavy lifting behind the scenes.

Making Your First API Call

To start using the merging functionality, you'll need to send a POST request to the /api/merge_image_audio endpoint. The request can include arrays of image and audio URLs, allowing you to manage multiple pairs seamlessly.

Here's how to structure your JSON request for a multi-pair video:

{
  "image_urls": [
    "https://example.com/intro.jpg",
    "https://example.com/chapter-1.jpg"
  ],
  "audio_urls": [
    "https://example.com/intro.mp3",
    "https://example.com/chapter-1.mp3"
  ],
  "transition_effect": "fade",
  "transition_duration": 0.75,
  "dimensions": "1280x720",
  "zoom_effect": true,
  "async": false
}

Practical Example with Curl and Python

Using the curl command, you can easily test the API from your terminal. Here's how to send a request to merge images and audio:

In Python, you can also leverage the requests library to interact with the API. Below is a sample code snippet:

curl -X POST https://ffmpegapi.net/api/merge_image_audio \
  -H "Content-Type: application/json" \
  -d '{"image_urls": ["https://example.com/intro.jpg", "https://example.com/chapter-1.jpg"], "audio_urls": ["https://example.com/intro.mp3", "https://example.com/chapter-1.mp3"], "transition_effect": "fade", "transition_duration": 0.75, "dimensions": "1280x720", "zoom_effect": true, "async": false}'

import requests

url = 'https://ffmpegapi.net/api/merge_image_audio'
data = {
    "image_urls": ["https://example.com/intro.jpg", "https://example.com/chapter-1.jpg"],
    "audio_urls": ["https://example.com/intro.mp3", "https://example.com/chapter-1.mp3"],
    "transition_effect": "fade",
    "transition_duration": 0.75,
    "dimensions": "1280x720",
    "zoom_effect": true,
    "async": false
}

response = requests.post(url, json=data)
print(response.json())
