[ndnSIM] ndnsim and video trace files

Let me ask this in a different way. Is it possible with ndnsim to accept
data packets without interest packets? That is, what would be a reasonable
way to implement a UDP equivalent with a single initial interest request
and the acceptance of subsequent stream of data packets?
