Reserving a signal for libvlc is troublesome. But in any case, the timer
handler needs to be able to use at least mutexes, and those are not safe
from without signal handlers. Namely the signal handler can be called from
a thread that is locking the same mutex, and caboom.

I think the sanest option is to emulate it using pthread_create() and
nanosleep(). That should be fairly straightforward.
