Video streaming based on V2X technology is possible, but not very feasible in the open field.
The V2X protocol is mainly designed for sharing the status of vehicles and emergency road events; basically, there should not be any station that bursts packets or occupies most of the bandwidth.
For the request of video streaming or high data rate transmission, Unex recommends combining the V2X technology with some other wire/wireless communication system (E.g. LTE-Uu) to meet the low latency requirement of V2V direct communication and high data rate requirement of video streaming.
