hi, and thank you for the great job!
about the fallback, now i think that we can only fallback from one codec
to the same codec. (mp3 to mp3...aac to aac)
it will be great if we will can to fall back from aac to mp3...
consider that :-)
We’re implementing fallback on HTML5 version now.
On this version, we’ll support fallback from different codecs :)
AS You could make it to selection the kind of stream automatically
