What I want: To add watermarks to all video files that are uploaded to the S3 bucket (mov, mp4, etc.). Then overwrite the file with it's same name with the newly transcoded file that has the watermark on it.
So, I was able to manually do this by creating a pipeline and job with elastic transcoder, but this is manual. I want this done the moment a file is uploaded to the server, overwrite the file with the new file and boom.
One, this should be a feature already but not sure why it isnt.
And two, How can I have this automatically done? Any advise? I know its possible just not sure exactly where to start here
You need S3 bucket, a lambda along with your transcoder pipeline.
Elastic transcoder is backbone of your process.
To automate transcoding, create lambda function which gets triggered by an S3 event .
More detailed explanation is here .

I have a link in a request which is pointing to some pdf /image content type. My requirement is to upload the content in the link to the s3 server.
Do I have to download it and then uploading the file but I have to many call and limited file storage in the machine Or Is there any other way to achieve this.
You must upload the file to Amazon S3.
It is not possible to tell Amazon S3 to retrieve a file from a URL.
My requirement is to upload the content in the link to the s3 server.
we - you need some compute resource. S3 itself won't do that.
Do I have to download it and then uploading the file
Or Is there any other way to achieve this.
The compute resource (logic) doesn't need to reside on your computer. You may use some AWS Compute resource near the S3, such as Lambda, EC2, ECS, .. You may decide based on the predicted load or other requirements.
I am new to AWS. Most of example I have seen need an input file name from S3 bucket for media convert. I want to automate this process. What is the best way to do it. I want to achieve following.
API to upload a video(mp4) to a S3 bucket.
Trigger MediaConvert Job to process newly updated video and convert it to HLS.
I know how to create an API as well as MediaConvert job. What I need help with it is automating this workflow. How can I pass recently uploaded video to MediaConvert job dynamically?
I think this should actually cover what you're looking for, and is straight from the source:
https://aws.amazon.com/blogs/media/vod-automation-part-1-create-a-serverless-watchfolder-workflow-using-aws-elemental-mediaconvert/
Essentially, you'll be making use of AWS Lambda, a serverless code execution product. Lambda functions by allowing you to hook directly into "triggers" or events from within the AWS ecosystem (like uploading a file to S3).
The lambda can then execute code in a number of supported languages like Javascript or Python, which can be used to execute a MediaConvert job on the triggering object (the file uploaded to S3).
Some images which is already uploaded on AWS S3 bucket and of course there is a lot of image. I want to edit and replace those images and I want to do it on AWS server, Here I want to use aws lambda.
I already can do my job from my local pc. But it takes a very long time. So I want to do it on server.
Is it possible?
Unfortunately directly editing file in S3 is not supported Check out the thread. To overcome the situation, you need to download the file locally in server/local machine, then edit it and re-upload it again to s3 bucket. Also you can enable versions
For node js you can use Jimp
For java: ImageIO
For python: Pillow
or you can use any technology to edit it and later upload it using aws-sdk.
For lambda function you can use serverless framework - https://serverless.com/
I have made youtube videos long back. This is related to how get started with aws-lambda and serverless
https://www.youtube.com/watch?v=uXZCNnzSMkI
You can trigger a Lambda using the AWS SDK.
Write a Lambda to process a single image and deploy it.
Then locally use the AWS SDK to list the images in the bucket and invoke the Lambda (asynchronously) for each file using invoke. I would also save somewhere which files have been processed so you can continue if something fails.
Note that the default limit for Lambda is 1000 concurrent executions, so to avoid reaching the limit you can send messages to an SQS queue (which then triggers the Lambda) or just retry when invoke throws an error.
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
So I have an S3 bucket full of over 200GB of different videos. It would be very time consuming to manually set up jobs to transcode all of these.
How can I use either the web UI or aws cli to transcode all videos in this bucket at 1080p, replicating the same output path in a different bucket?
I also want any new videos added to the original bucket to be transcoded automatically immediately after upload.
I've seen some posts about Lambda functions, but I don't know anything about this.
A lambda function is just a temporary machine that runs some code.
The sample code in your link is what you are looking for as a solution. You can call your lambda function once for each item in the S3 bucket and kick off concurrent processing of the entire bucket.
