I have a EC2 AMI image that I've tweaked and customized for my needs. I need to use the Transcoder AddOn to be able to generate a few more streams for iOS from my main input streams. I've set up the transcoder configuration, but I don't see in the logs that my streams are being transcoded at all. I went here (http://www.wowza.com/ec2-streaming.html) and read that no addons are supplied for EC2 AMI images. Is this really the case? Can I not use AddOns with EC2?
