Hi, I've just finished a similar project that connects to GoPro HERO 3+ and 4 cherokee wifi server and shows to the client part of a movie.
I could remake this app for you if you want and just push what I get from GoPro to your Wowza.
We used FFMpegiOS in that project. It is ffmpeg itself compiled for ios and osx platforms, and libavcodec native C/C++ code - so all tricks are possible.
I'm a software engineer with over 10 years of experince in business and recently. Last year I was working with Wowza and iOS apps which are clients of tv and radio streams. I also have knowledge about Red5 and about transcoding and broadcasting in general. I very often look in freelancer for interesting challanges and this looks like one, so...
If you are interested in my offer, please let me know. Especialy let me know if you have some crazy deadlines for the task, because this is a bit advanced programming and have to have some reasonable time margin for suprising challanges.
I recommend my services.
Sincerely,
mk
