I still need to try that option, I don't know if getting a va_list as a void* in a callback, and passing it back to a native function (like vasprintf, that uses va_copy...) will work on all platforms. This feels quite wrong to assume that va_list is just a pointer.

Moreover, we would need a libvlc_vasprintf exposed anyway, and from what I've read from Remi's comments, that's not really wanted either? I'd really prefer the "already formatted" way.
