In the world of content creation and multimedia applications, merging images and audio into engaging videos is a common requirement. With FFMPEGAPI.net, developers can leverage a powerful hosted REST API to achieve this functionality without worrying about server setup or FFmpeg infrastructure management. In this article, we will explore the 'Image and Audio Merge' feature of FFMPEGAPI.net and demonstrate how it can simplify your workflow.

What is the Image and Audio Merge Endpoint?

The '/api/merge_image_audio' endpoint allows you to create MP4 videos by combining one or more pairs of images and audio files. This functionality is essential for developers looking to automate video creation, enhance content delivery, or build interactive applications.

Using this API, each image can be displayed for the duration of its corresponding audio file, creating a seamless viewing experience.

  • Supports both single and multiple image/audio pairs
  • Offers optional image transitions and slow zoom effects
  • Requires simple JSON requests for complex video creation

How to Use the Merge Image and Audio Endpoint

To utilize the merge functionality, you need to send a POST request to the '/api/merge_image_audio' endpoint. The request can be made in JSON format or as multipart form data.

You can send an array of image URLs paired with corresponding audio URLs, ensuring both arrays have the same item count.

  • Optional parameters include transition effects, dimensions, and zoom effects.
  • Asynchronous processing is available for larger tasks.
import requests

url = 'https://www.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
}

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