Research on the QoS Guarantee for H.264 Video Stream Transmission Based on RTP
Zhanjun Zhang · Journal of Academy of Armored Force Engineering · 2006
In this paper, the author proposes a layout about the transmission of H.264 Video Stream, based on RTP/RTCP and under the Linux environment. The Video Stream gathered by calling the API functions of V4L, is compressed by x264, packed with RTP/RTCP and transmitted. With the feedback of RR and the formula of Volume of Handling, the approximate bands are calculated. Taking the start_qp as the adjustment parameter of Video encoder, the adjustment parameter of Video encoder is controlled by the approximate bands to achieve the goal of controlling output code rate, and realizing the video transmission QoS guarantee.
