      There is 3 simple steps to so this:

      1. Implement ffmpeg
      2. produce mpeg
      3. profit

      If you need some help or deeper information, please be patient and give us a lot more information about your problem, or wait for a clairvoyant ....

        I have implemented the ffmpeg libraries in order to produce mpeg file and to stream live throws network but I'm not happy. I memory leaks, in some cases I ca'n produre ogg or other formats... I have much delay on live... Somebody knows that exists other libraries?

          You can try libVLC.

          Are the memory leaks from FFMPEG, or from your program? How did you check?

            Wow! I didn't knew that this library exists.

            It's a very good question! Using valgrind I haven't found memory leaks. The application is active 24h and creates a new mpg file every 2 minutes. In this contest I see that the required memory goes to increment.
            The problem is that I haven't find an official way to implement libav libraries. Now I have the doubt that my ffmpeg implementation is not correct or ffmpeg (libav) is not perfect.
