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?

Hello,
Yes, I am directly appending data to a file.Now, I am looking into
output_example.c.
There is again a problem.
AVFormatContext* fmt = guess_format(NULL, "c:/testFile.mp3", NULL)
gives NULL.
Any idea why?
I tried number of options AVFormatContext* fmt = guess_format("mp3",
"c:/testFile.mp3", "audio/mp3");
AVFormatContext* fmt = guess_format("mp3", "c:/testFile.mp3", NULL);
AVFormatContext* fmt = guess_format("mp3", NULL, NULL);
Everytime it gives fmt is NULL.
I need to assign this AVFormatContext.oformat variable to proceed
ahead with output_example.c
Instead of using guess_format(); I used guess_stream_format without
sucess.
Thanks,-Amol.

you simply put encoded frames to file or you are using avformat?
look at libavformat/output-example.c

Hello,
I get raw sudio stream from Mic using Microsofts DirectSound
APIs. To compress it (MP3) , I used avcodec_encode_audio() function
from libavcodec.dll. The function successed and gave be some bytes
which I appended to a file. But when I play this file, it plays
FASTER.
Any thoughts what I should do to play this file at slower rate?
Thanks,
