Why don't you just check the addresses of the data planes and know it? It's 2 minutes to check a few times. > > 2.

The specific code to deal with each codec type will be radically different - undefined, remember. This isn't a alignment question as in 'off by one sample', it's an alignment issue as in vector operations won't work right.
