Is there any way I can get AVOutputFormat*???guess_format("mp3", NULL, NULL) is
not working.
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.
Thanks in advance...

You can do something like that:
aOutputFmt = guess_format("mp3", NULL, NULL);
in case if format not found you should get error message, shouldn`t you?
