    a question about 3gp

    hi all:
    i download a video file from the internet. when i playing it using KMPlayer, i can get the media information about it: the audio codec name is "AAC". after putting it on the server, i download the data of the file with live555, then i find that, the audio codec name is "MP4A".
    how does it happen? and what the relationship of the two codec? are they the same?
    thank you!

    Re: a question about 3gp

    Hi,

    I believe they are the same thing with different names, just like the two URLs link to the same wiki page.

    http://en.wikipedia.org/wiki/Mp4a
