Hi Usually ,to stream video data ,it is fragmented into chunks of 1400 bytes or so and packetized as Rtp payloads . So saying that fragmented packets becomes mandatory for video streaming is not true .There are many RFC that dictate how to do that .Like RFC3016 defines such things for MPEG-4 data .
