Amazon Cloudfront – Video Streaming (rtmp) Issue?

Are you using Amazon Cloudfront for public/private video streaming over rtmp? Having trouble to figure out why some of your videos fail to stream (over rtmp) and throw ‘Stream not found’  flash/actionscript client side errors?

I have figured out:

  • Videos with invalid chapter markers would not stream over rtmp (Adobe Flash Media Server) or via Cloudfront.
  • Adobe’s FLVCheck utility suggests our videos have invalid chapter markers. I am not sure, if chapter markers in our videos are invalid or Adobe Media Server expect those to be in different format.
  • Same set of videos play fine with Quicktime/VLC player, Adobe Flash Player (over http progressive download) and html5 player (chrome or others which support H.264 videos)

I am disappointed with the fact – Adobe Media Server ceases to play (core feature) a video because of (optional feature?) chapter marker(s) which can be ignored if it is corrupt or invalid.

Thanks to AWS engineers who confirmed the case, and provided more details.

Update: Thanks to Justin Riley for sharing a solution (in comments below). He suggested to use ‘-map_chapters -1′ to get rid of this issue. It works for me.

Adobe AIR and Flash Player Incubator program

The Adobe Flash Platform runtimes team has launched Adobe AIR and Flash Player Incubator program, which would showcase bleeding-edge, under-development or under-consideration features of Adobe AIR and Flash Player builds.

Unlike Adobe pre-release program(s), Incubator program is open to everyone, and encourages companies and developers to look at under development features, and also give feedback to shape the future of these runtimes.

This launch is another major milestone, after Adobe Labs and Open Source initiatives by Adobe. We are heading in right direction.

“Molehill” 3D APIs and Cubic Bezier Curves are the first two features available in incubator build. I am sure, there would be more features available in coming months.

BTW! These early features might not make to final release of runtimes, as it’s always case with
