how to play an encrypted file in Android.

Question

I need to be able to play an encrypted file in Android.

The file is AAC.

The only way I can see to do this is either:

1. decrypt the file to internal private storage and point the player at that file to play, or
2. decrypt & decode the file to pcm and feed it to an AudioTrack.

1 isn't great because it takes a long time to do that.
2 isn't great either because I don't know how I can take advantage of the HW decoder to do this.

Any ideas?

Answer 1

Well I think Android does not support .AAC format.

 3GPP (.3gp) and MPEG-4 (.mp4, .m4a). No support for raw AAC (.aac)

but you could change the file playerdriver.cpp inside the Android OpenCORE the following line::

mDataSource->SetDataSourceFormatType(PVMF_FORMAT_UNKNOWN); 

to

mDataSource->SetDataSourceFormatType(PVMF_AACFF); 

then you could play your AAC file =)
