Implement HTTP Live Streaming (HLS)

The demo below encodes a video into three high-quality versions, before pushing them into the /video/adaptive Robot, which cuts them into several segments and generates playlist files containing all the segments.

The /video/adaptive Robot also generates an HLS master playlist file - a playlist of playlists, so to speak. Lastly, all the files are stored in your Amazon S3 bucket. The trick here is that all files are already stored in the proper location to make the playlist work. This is done using the special "${file.meta.relative_path}" variable.

Our /video/adaptive Robot also supports MPEG-Dash. For more information about that, please check its documentation.

/upload/handle Robot

This bot receives uploads that your users throw at you from browser or apps, or that you throw at us programatically

2. Transcode videos to HLS (270p) (H.264)

We offer a variety of video encoding features like optimizing for different devices, merging, injecting ads, changing audio tracks, or adding company logos. Learn more ›

/video/adaptive Robot

This bot encodes videos into HTTP Live Streaming (HLS) and MPEG-Dash supported formats and generates the necessary manifest and playlist files

6. Export files to Amazon S3

We export to the storage platform of your choice. Learn more ›

:original

s3.amazonaws.com/demos.transloadit.com/hlsdemo/360s10f.mp4

adaptive

Once files are exported, we ping you back with the Assembly status JSON.

"exported": {
  "robot": "/s3/store",
  "use": [
    "adaptive",
    ":original"
  ],
  "path": "hlsdemo/${file.meta.relative_path}/${file.name}",
  "credentials": "demo_s3_credentials"
}

/s3/store Robot

This bot exports encoding results to Amazon S3

Since this is a store robot, be sure to use Template Credentials so that any sensitive data is encrypted and stored in our database, making sure that they’re never exposed to any end-user.

Try it yourself

This live demo is powered by Uppy, our open source file uploader that you can also use without Transloadit, and tus, our open protocol for resumable file uploads that is making uploading more reliable across the world.

So many ways to integrate

Transloadit is a service for companies with developers. As a developer, there are many ways you can put us to good use.

Bulk imports

Add one of our import Robots to acquire and transcode massive media libraries.
Handling uploads

We are the experts at reliably handling uploads. We wrote the protocol for it.
Front-end integration

We integrate with web browsers via our next-gen file uploader Uppy and SDKs for Android and iOS.
Back-end integration

Send us batch jobs in any server language using one of our SDKs or directly interfacing with our REST API.
Pingbacks

Configure a notify_url to let your server receive transcoding results JSON in the transloadit POST field.

We are a Swiss Army knife for your files

Implement HTTP Live Streaming (HLS)

1. Handle uploads

2. Transcode videos to HLS (270p) (H.264)

3. Transcode videos to HLS (360p) (H.264)

4. Transcode videos to HLS (540p) (H.264)

5. Convert videos to HLS

6. Export files to Amazon S3
