mp4v2 extracting and decoding data from .M4A file

I have extracted the audio data from .m4a file using mp4v2 library (sample-by-sample). Does this library have function that decodes the data? Anybody with experience with this library and can provide some help?

The documentation says:

MP4ReadSample function reads the specified sample from the specified track. Typically this sample is then decoded in a codec dependent fashion and rendered in an appropriate fashion.

I am interesed in decoding the output.

Thanks in advance.

Solution

  • I have researched everything and the answer is NO. There is no decoder in mp4/mp4v2 libraries. One has to use some other library to do that.
