Recently, many users frequently asked questions about YUV-to-RGB conversion. Here I will give a unified answer and sample code for your reference (using yv12-to-rgb24 as an example ). Yv12 bytes are arranged as follows: Yyyy... Yyyy ^Y |.. Height... |Yyyy... Yyyy vVV... VV ^... |VV... VV heightUU... UU |... |UU... UU v The format of rgb24 bytes is as follows:Bgrbgr... Bgrbgr ^... |.. Height... |Bgrbgr... Bgrbgr v For details about pixel layout and wor

Recently, a pcrf system was developed, and the GX interface was used between pcef and pcrf Based on the Diameter protocol. Some problems occurred during the debugging process, I wanted to convert the message into XML format, but it was too troublesome. So I thought of Wireshark and checked whether it could support the Diameter protocol. First, use tcpdump to capture packets on the server: SudoTcpdump-S 0-vvv-I lo TCP and host 127.0.0.1 and/(Port 686

Anyone familiar with XPath knows that using the translate function in XSL can replace a string by character. For example: Translate ("bar", "ABC", "ABC") will get the bar Translate ("-- AAA --", "ABC-", "ABC") will get AAA. However, if you want to replace a substring with another substring, you cannot use translate for xpath1.0. Generally, there are two methods to replace strings in XSL: (1) Use MS: script to embed the XSL implementation, but the XML Parser must be MS. (2) Use a pure XSL templat
