FFmpeg library: Muxing audio from external file

I have successfully changed the muxing.c sample to use video frames that I generate on runtime.

I am trying now to replace the get_audio_frame function with a function that decodes an existing audio file, and writes its samples instead of the synthesized audio-samples in the example code.

I've tried using the "audio decoding" example to decode the audio file, but the not sure how / when to write the samples decoded.

I suggest to check the source of my Karaoke Lyrics Editor which is doing exactly what you need based on ffmpeg. See ffmpegvideoencoder.cpp, see createFile and encodeImage functions.
