Hi,
thanks for the reply but your answer didn't help. first of all, i need to
register a codec and open it automatically, but decode_audio.c did not show the
right way.
second, I copied a third party demo, it works well but still have some warning
for the OLD API and decode_audio.c did not use the latest API to demostrate
what ffmpeg suggest to do. I need a perfect demo, anybody could help?
Best regards,
pp

Hi,
that's the demo I tried
with warning 'avcodec_decode_audio4' is
deprecated.
and that demo could not work with : Codec not found.

Usually, if you get "codec not found" it means your ffmpeg
compilation was lacking a certain codec. The audio example uses mpeg2
audio, so you need to have ffmpeg compiled with mpeg2.
You can check the codecs you have by doing:
$ ffmpeg -codecs
For it to work, you should have a line like:
DEA.L. mp2 MP2 (MPEG audio layer 2) (decoders: mp2
mp2float ) (encoders: mp2 mp2fixed )_______________________________________________
