Adobe Air , NativeProcess and ffmpeg
18 août 2013, par Tom LecozFirst of all, please excuse me if my english is not perfect, I hope you could understand me...
I discover yesterday this video tutorial about Air Native Process and FFMPEG, it shows how to create an Air app that can read every video format (avi, mkv, ...).
http://www.youtube.com/watch?v=6N7eN9wvAGQ
I tryed to reproduce it but obviously it didn't work...
Then I looked for an example of it, with working source code, on the internet. I found this
http://suzhiyam.wordpress.com/2011/05/05/as3ffmpeg-play-multi-video-formats-in-air/
The author said it's a document class for a Flash project, it just need a button component, a text area and a video Object.
I tryed it inside a Flash project, it didn't work...
So, I made some adjusment to run it outside Flash (I just replaced the DisplayObject on the stage by ActionScript code), just because it easier if you want to test it.When I say "it didn't work", I mean my video is not read at all. The nativeProcess is working, my executable is recognize but I always get some ProgressEvent.STANDARD_ERROR_DATA and then the process stop...
I'm working on Windows 7 64 bit.
I tryed with FFMPEG 32 & 64 bit and get the exact same (no) result.You can find my code here

Thanks by advance !
