Is there any service on AWS that can help me convert mp4 files to mp3?

I'm new to Amazon web services and I'm wondering if the platform offers any solution to convert media files to different formats ( mp4 to mp3) or do I have to use a lambda function with a third party library to achieve this. Thank you !

You can get up and running quickly with Elastic Transcoder. You will need to:

• create two s3 buckets, your 'inbox' and 'outbox'
• add a transcoder pipeline specifying which bucket is your in/out buckets, and you what file types you want to transcode from and two.
• you can set up a trigger so that every time something hits the in bucket, the process runs, or you can place something in the in bucket and use the sdk or cli to trigger a job.

Two things to note:

• When you fire a job, you have to pass in the name of the file that will be created. If the file already exists in the out bucket, an error will be thrown.
• As with all of aws' complete services, you get a little free up front, then it gets expensive. Once you get the hang of it, you can save some money rolling your own in lambda like this
