soloud Support for mp4 /AAC codec

Would it be possible to add support for MP4 files encoded with the AAC codec?

I doubt it, but if a library for decoding them exists out there with liberal enough license, I'll consider it.

I am not sure, which features would be required for the decoding but here is a repo under the Apache 2 license for aac decoding and encoding in c++ https://github.com/mstorsjo/fdk-aac

Yeah, well, unfortunately the SoLoud project is under "extremely liberal licenses", and that doesn't count as one.

"Parts of the SoLoud package were not made by me, and those either have a similar license, or more permissive (such as Unlicense, CC0, WTFPL or Public Domain)."

So I guess it needs to be the ones listed above or MIT-0 or 0BSD for Public Domain right?

So I guess the following can't be used either https://android.googlesource.com/platform/external/aac/+/6792cf6361ff339e336287affb0bfe54bf6957a9/libAACdec/src/aacdecoder_lib.cpp https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/aac/aacdec.h (GNU Lesser General Public License)
