Very cool! I've recently open sourced a good portion of my game broadcasting SDK, which now has a few people using it for purely making camera apps to stream to RTMP services. Mine is not nearly as refined as this one, nor do I have any sort of CDN heh. Congrats guys, looks awesome.

Thanks man! I really appreciate it. All of our streams are HLS rather than RTMP, although we do have RTMP support working in the SDKs, we don't plan on making that a priority product focus right now - HLS and DASH are the future. Kickflip will likely officially support RTMP in the 1.1 versions of the SDKs. Thanks again for your support!

Hey https://github.com/jamesghurley/VideoCore https://github.com/jamesghurley/VideoCore looks great, wish I knew about it earlier.

  Thanks! It's a side-project but I try to fix any bugs as quickly as I can and I've got some new features planned/in development for the future.

Wow, if only I knew about VideoCore earlier! I used a modified version of Geraint Davies temp .mp4 file hack, but it looks like you developed a great alternative.

  I've never actually seen this code before. I find it interesting that he found that the frames were arriving 500ms after capture, but I've used a similar technique (to how I did it in VideoCore) for video conferencing that achieved much, much lower latency than that. I wonder if that's something that was true in 2010 but is no longer true. I also haven't really encountered much of an issue with frame reordering, but as it is I mostly don't care about that. I have noticed, however, that as of iOS 7.0.4 or so the encoder can output multiple slices per frame which it previously didn't do (or at least I never caught it doing it anyway)

    Yeah I made modifications to disable frame reordering and handle the extra SEI information properly, but I'll study your solution too because it seems really awesome. The lower the latency the better :)
