The Media Transport Library(Kahawai) is a solution based on DPDK prepared for transmitting and receiving high quality video with low latency. It include a compliant implementation to the SMPTE ST 2110 Professional Media Over Managed IP Networks suite of standards.

• ST2110-10, ST2110-20, ST2110-21, ST2110-30, ST2110-40, ST2110-22, ST2022-7
• 1080p, 720p, 4k, 8k and other
• FPS: 120, 119.88, 100, 60, 59.94, 50, 30, 29.97, 25, 24, 23.98
• All the video format listed in ST2110-20, include YUV 4:2:2 10bit and others.
• CSC support status: status

Media transport library takes advantage DPDK features to implement a highly efficient, real-time & low-latency media transport stack, software based media transport makes it feasible for edge and cloud deployment based on COTS hardware.
Kahawai introduce a tasklet async based scheduler to fully utilize CPU resources, easy integration with different packet processing unit and accelerators.
The packet pacing module support different ways(algorithm) to acheive narrow pacing, RL(rate limit) is partially hardware offload while TSC is fully software based.
Kahawai also develope SIMD CSC(color space format covert), DMA, plugin interface to build a fulll video production ecosystem.

Please refer to build guide for how to build DPDK, the library and the sample application.
For Windows, please refer to Win build guide for how to build.

Please refer to run guide for how to setup and run the demo pipeline application.
For Windows, please refer to Win run guide for how to setup and run the demo.
For VF and VM support under Linux, please refer to vf guide for how to setup VF based on SRIOV, vm guide for how to setup VM based on VF passthrough.

For how to develop application quickly based on Kahawai library, pls refer to sample code.
