Hi All I am first time using ffmpeg library. I have one http site which have live music like FM. But the music file in .wma format and my media player just support .mp3 format. So I am not able to play .wma file. So i need to convert .wma format data to mp3 format, on the fly. Please suggest,How can I convert it ? and which API is useful for this process? or suggest any example... Thanks Mahendra
