Abstract: A pipeline video system is capable of transmitting rate adapted video. The pipeline video system receives a first video stream in real time from a camera at a first frame rate; receiving data link layer transmission statistics of a wireless interface. The system also generates a second video stream with a second frame rate from the first video stream by dropping one or more video frames of the first video stream based on the data link layer transmission statistics. Based on encoding parameters determined based on the data link layer transmission statistics, the system encodes the second video stream. The encoded second video stream is transmitted to the wireless interface for transmission.
