I have a wowza server on amazon, but i’m not sure what to fill in. I have an S3 storage with videofiles on it. the path to the files is s3bucketname/VIDEOLIBRARY/Mp4 the /usr/local/WowzaMediaServer/conf/application.xml I’m not sure about the storagedir. In normal installations, for me it is : ```auto J:/Matches/VideoLibrary/mp4 ``` but what do I need to put the to point it to the S3 storage? is this correct ? ```auto s3bucketname/VIDEOLIBRARY/Mp4 ``` ---

You need to use MediaCache to stream from S3. If you are using a pre-built Wowza EC2 AMI MediaCache is already installed and configured for use with an application named “vods3”. Otherwise you can install it yourself [https://www.wowza.com/docs/how-to-scale-video-on-demand-streaming-with-media-cache](https://www.wowza.com/docs/how-to-scale-video-on-demand-streaming-with-media-cache) For details on using MediaCache and the vods3 application, review the Wowza EC2 Guides, the 2nd group on this page: [https://www.wowza.com/docs/user-guides](https://www.wowza.com/docs/user-guides) Richard ---

You would use URL in the smooth player: ```auto http:// ***-** -20-162-208.compute-1.amazonaws.com:1935/vods3/_definst_/mp4:amazons3/videolibraryus/VIDEOLIBRARY/Mp4/9bad8e11-2da7-44ad-9e77-567320f6453c_a.mp4/Manifest ``` Richard ---

It is located at /home/wowza/conf/MediaCache.xml Enter the AWS keys near the bottom. Restarting Wowza is necessary. Richard ---

I already looked at that part. We use a silverlight client on our website sto stream the video, I have this working on a 2008 server with wowza also on a 2008 server. when I use the simplevideostreaming and put : server : rtmp://\ ***-** -20-162-208.compute-1.amazonaws.com:1935/vods3 and stream : mp4:amazons3/videolibraryus/VIDEOLIBRARY/Mp4/9bad8e11-2da7-44ad-9e77-567320f6453c\_a.mp4 it works, but now i have to get it working in my silverlight client. ---

This works good, thanks a lot ! the “public” files work, now i just have to turn authorization on. Where is the “tuning/MediaCache.xml” located?
