Yes, but "some assembly required" as the saying goes. AVMD only throws
events, so whatever solution you are using must be able to consume and
react to those events. The OP is using Lua which definitely allows you to
consume the events. There's even a really simple example on the wiki about
using the setInputCallback function to look for "events" and then do
something once the event comes in. It's a really sparse example but it
demonstrates how to catch an event. From there you'd need to put in your
commands. I'm assuming you'll need a break app or uuid_break API to stop
the current playback and then you'll need to queue up another playback.
It's also good to turn off avmd at this point as well. I'm just throwing
this out there off the top of my head, so I highly recommend some hands on
tinkering.

Please let us know what you end up doing. :)
