Try Live Demo

In this blog post, we’ll discover how to elevate your live streaming experience by uploading HLS files to S3 bucket in real-time using the Ant Media Server.

Ant Media Server supports uploading the HLS files to all the S3 compatible buckets like AWS S3, OVH object storage, Digital Ocean Spaces, Wasabi storage, and Google Cloud Storage, etc. In Earlier versions of Ant Media Server, the recorded HLS files were uploaded to the S3 buckets after the stream ended.

But starting from the Ant Media Server version 2.6.2, you can now seamlessly upload HLS files to the S3 buckets in real-time while your stream is live, hence delivering an instant and captivating experience to your viewers.


Before diving into the process of uploading HLS files to S3 buckets, it’s important to ensure you have the essentials in place. So before we begin, it is important to have your S3 bucket ready.

You can create your bucket on any S3-compatible cloud of your liking. If you’re not sure how to create an S3 bucket, please refer to our detailed document on how to create S3 buckets in different cloud platforms.

I’m going to use the AWS S3 bucket for this blog post. So now that the S3 bucket is ready and we have the required credentials, let’s go ahead and save the details.

Step 1: Saving the bucket credentials

The bucket details can be easily saved on the Ant Media Server dashboard by going to the Application > Settings > Enable S3 Recording under Stream Recording.

Step 3: Customizing the real-time HLS uploads

Now that we have learned to upload HLS files to the S3 bucket in real-time, let’s learn about the best practices and settings to make the most of this feature.

  • If you want to store all the .ts files for a streamId, it is important to set the below properties:
  • If using the same streamId and you need to prevent the HLS files from getting overwritten, you can enable the data and time for HLS files:

Using this property, when the same streamId is used, the existing HLS files will not be overwritten as they will have different timestamps.
