Although the actual bandwidth may be lower than the theoretical value, it is still very prone to bottlenecks, especially on the lower-end video card. Although the computing power of the video card is growing rapidly every year, the increase in bandwidth is relatively slow: geforce 6800 ultra 35.3 g/s, 7950gt 44.8 g/s, 8800gtx 86.4 g

format yuy2, the missing u and v sampling needs to be interpolated during rendering. Yuy2 only lacks u and v sampling on an odd number of pixels. In this way, the parity pixels need to be differentiated. For an even number of pixels, U and V interpolation is not required to directly convert the color space. For odd pixels, adjacent u and v samples must be used for interpolation. Catmull-Rom interpolation or linear interpolation can be used. After interpolation, you can convert the color space.

IPv6, connect it to the IPv6 address of the server. The sample code is as follows: TcpClient client = new TcpClient(AddressFamily.InterNetworkV6); client.Connect("fe80::14d8:a209:89e6:c162%14", 9900);Iii. UDP For UDP, the server and client can adopt the same model. It is a little complicated to make UDP-based applications compatible with IPv6. (1) create two UdpClient instances, one for IPv4 and the other for IPv6. The sample code is as follows: int port =
