• Adobe Air , NativeProcess and ffmpeg

  18 août 2013, par Tom Lecoz

  First 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

  Can someone help me ?

  Please ! :)

  Thanks by advance !

• Cannot use FFmpeg in Xcode iOS Project (file .h not found)

  19 mars 2016, par BlackBox

  I followed almost step by step this guide.

  Almost because I downloaded, as a user suggested, ffmpeg ios library already built from here

  I followed from "Linking static libraries in Xcode" but I cannot import anyway the header files of ffmpeg. (So I got the .a files)

  For example

  #include "avformat.h"
  
  // or
  
  #import "libavformat/avformat.h"
  
  // or
  
  #import <libavformat></libavformat>avformat.h>

  Everything that I use does not work.

  I specify that those .a files are currently in my project directory, indeed, if I import the .a file, it doesn’t complain that it isn’t found, but when compiling, it complains about UTF-8 stuff because .a files are object libraries and cannot be imported that way.

  I put also the Header Search Paths for the project as it was suggested and the config.log file but nothing.

  Also I see libraries are missing from every project example of FFmpeg I was able to find on GitHub.

  Any ideas ?

• Need help transcoding Red5 RTMP stream to MPEG2-TS

  5 février 2014, par reyniraron

  Me and my friend are going to make live shows and for that purpose I have set up a Red5 server on my old 2006 Intel Core Duo Mac mini running Mac OS X Snow Leopard Server 10.6.8.

  I use Flash Media Live Encoder to broadcast to Red5's oflaDemo application and the stream works great, except for the fact that I want the stream to work with iOS.
  I am developing an app for it, but I still need to convert my stream to Apple's HTTP Live Streaming protocol for it to work.
  Can anybody help me convert the RTMP stream to MPEG2-TS, because that's the format that mediastreamsegmenter supports ? I already have Apple's HTTP Live Streaming Tools installed on the server, so the segmenter's not a problem.

  FFmpeg doesn't work, at least not with the code I found here. With it a always get an "Operation not permitted" error. Xuggler doesn't work, not even with a Linux box.
  Can anybody please help me ? I'd really, really appreciate it.
