We use Wowza as a method to send RTMP streams from Wirecast for live broadcasting. The person who originally set this up for us used Flash. We now have to convert the stream to use HTML5. And the person who set this up for us is no longer available. Is there anybody who can help with the conversion?
If you mean that you used Flash to capture a webcam and send that to a Wowza Server over RTMP, then the best replacement is probably WebRTC.
If you’re looking to hire someone to help/guide you with the transition, then you may post a message in the Find A Consultant forums: Hire a Consultant - Wowza Community
Here are a few useful links about WebRTC in Wowza
