X-视频运动补偿 (XvMC) 是一个X.Org Server的扩展。XvMC API可以让视频程序转移部分解码工作到GPU。Particularly, features that have the tendency of heavily depending on the processor. Since XvMC acceleration takes the load off the CPU, thereby reducing processor requirements for video playback, it is an ideal solution for HDTV video playback scenarios.

注意: XvMC 如今已被 VA-API 和 VDPAU 淘汰。它们对新款的GPU有着更好的支持。
