Hi,
I want to upload a video file to my S3 input bucket –as soon as a Wowza file write is complete- so the Amazon Elastic Transcoder can transcode the file.
**Is there a way to tell Wowza to execute a program after a file write is complete?**
I found the [IMediaWriterActionNotify](https://www.wowza.com/docs/how-to-use-imediawriteractionnotify-to-programmatically-move-and-rename-recordings-of-live-streams) and I did the following:
1. Installed Wowza IDE
2. Followed the Project and Module Class Creation (from [here](https://www.wowza.com/uploads/developers/WowzaIDE_UsersGuide.pdf)) to create a Wowza Media Server Project
3. At this point, if I run/debug the sample code, onAppStart, onAppStop, etc. are not being called.
4. Then I edited the MyFirstModule class and pasted the example code from [IMediaWriterActionNotify](https://www.wowza.com/docs/how-to-use-imediawriteractionnotify-to-programmatically-move-and-rename-recordings-of-live-streams)
But for some reason, the onFLVAddMetadata and onWriteComplete are not being called. Does anybody know what I am missing here?
Thanks!!

Hello there and welcome to the Wowza support forum.
Did you add your module to the application?
[Configure modules](https://www.wowza.com/docs/how-to-get-started-as-a-wowza-streaming-engine-manager-administrator#configModules)
If so, do you see any indication of the problem in the logs?
Kind regards,
Salvadore

Hi I recommend if need upload from Wowza to S3 use Java SDK with MultipartUpload, try to don’t use s3fs, the performance is terrible! I start one project using s3fs and we has many issuel uploading, after move to AWS Java SDK upload, the performance is impressive 20mb in 1 sec.
On the other hand can use the New AWS Lamda service to run events after a new s3 object be created in you bucket, and send them to ElasticTranscode.
hope this help!

Sorry, I forgot to mention the built-in file mover module that you might be interested in trying as well:
