• Compiled file for ffmpeg - iphone audio

  3 avril 2012, par Sreekumar Kalarikkal

  I would like to build an iPhone application which streams internet radio stations which includes .wma files also. So I found that in-order to play wma files, we need FFMPEG compiled files. I tried to build FFMPEG for iPhone, but having errors. I followed the guide here,

  I can able to build ffmpeg, but when I run the project using that library, I am getting the following error.

  So I think anybody of you may be successfully compiled and used this. If yes please give me some instructions to do this.

  Or if you can find the solution for the error. please let me know.
