First, my engilsh is poor, so you'll find it hard to read, sorry.....D:
In H264 video files, Advanced Audio Codec is generally used.
The audio stream coding by AAC with LC profile can keep a good quality in low bitrate.
So I think, we can use AAC instead of MP3/OGG for BGM, it can help to reduce the files size.
I'm sure it can help to reduce server load when a mess of download/upload operation.
OK, now return game play......lol
