Mediacache on Amazon S3

Dears,

we have a Wowza instance on AWS with mediacache add-on installed. I try to stream a mp4 file from S3 bucket but get the error

WARN server comment 2013-10-17 16:20:50 - - - - - 1951.662 - - - - - - - s3/s3-eu-west-1.amazonaws.com/wowzastreamingdemo/test.mp4 MediaReaderH264.open[1]: java.io.IOException: MediaCacheRandomAccessReader.open: Item not in cache: s3/s3-eu-west-1.amazonaws.com/wowzastreamingdemo/test.mp4

I have a bucket on s3 with this url: https://s3-eu-west-1.amazonaws.com/wowzastreamingdemo/test.mp4

and my MediaCache.xml file is this:

The url for playout is this

Server: rtmp://[wowza-address]/mediacache

Stream: mp4:s3/wowzastreamingdemo/test.mp4

Not sure why, but one quick and dirty way to get going for you will be to set /BasePath to “https://s3-eu-west-1.amazonaws.com/” and isAmazonS3 to “false”. Then I can stream your test.mp4.

But let me look further, I don’t think the AWS keys will work with isAmazonS3 set to “false”

I tried setting s3BucketNameInDomain to “false”, but that did not work, and there isn’t a bucket name in the domain.

This works:

I changed the MediaCacheSoure /Name to “http2” to avoid duplicate on your side.

I change /BasePath to “http://s3.amazonaws.com/

And /isAmazonS3 and /s3BucketNameInDomain to “true”

Note that the The Wowza EC2 pre-built AMIs come with MediaCache installed and a MediaCache application named “vods3”.

Richard

It’s working here. Did you restart Wowza? after making those changes? Did you use the MediaCache source I showed?

Richard

Using the Wowza example VideoOnDemand Flash RTMP player.

Server: rtmp://[wowza-address]:1935/mediacache

From what I can see in that screen shot you have left out “rtmp://”
