using ogg or mp3 with android?

1.What are the benefits if using oggvorbis over mp3 in android?

2.if we use ogg vorbis,is it possible to change its header开发者_运维知识库(xor or encryption) and make it unplayble?

The problem is more specific to encryption rather than using ogg or mp3, I had a similar issue where client wants that the downloaded images can only be viewed through his apps, what I applied is I cut the 32 bytes from the beginning of every file and write it database and when I want the resource to be used I pick that 32 bytes and the original file to make usable file at some hidden location.

I hope the point is clear and might help.
