Roku does support music only AAC, just not via Shoutcast. For progressive download and (theoretically, haven't tested this yet) HLS audio only, AAC is supported.
Could AAC work for local media streaming channels like Roksbox?
I tried just naming the song "NAME.aac" but that did not work.
Roksbox just skipped over that song and went to the next one.
(Yes, my song seemed to be a properly made AAC.)
The USB media list does include AAC. I would like to see if AAC
can be supported by local streaming methods.
And if not, could this be added to the wish list for the next release?
Note for people that don't know, AAC seems to be twice as good as
MP3 at compression. Thus, a 128Kbps AAC stream is equivelent in
quality to a 256Kbps MP3 stream.
