I did create AVOutputFormat* pOutputFormat = new AVOutputFormat; pOutputFormat->audio_codec = CODEC_ID_MP3; sprintf(pOutputFormat->filename, "c:/testSound100.mp3"); But when I use this pOutputFomat in av_set_parameters(pOutputFormat, NULL);; it gives exception. I guess something is not filled that av_set_parameters is trying to access.
