A while ago looked at the official reference software JM of the source code, here to summarize its structure. JM codec the speed is very slow relative to the ffmpeg, but its code is written clearly and understandable, more suitable for academic research. JM contains video decoder ldecod and video encoder lencod. This document records the structure of the video

The scanned control is a view, and the user simply needs to stick it in their own controller. Other UI users can add them at their own controller. The code is as follows- (void) viewdidload {[Super viewdidload]; //Scan active area (i.e. transparent area within the box)CGRect Interestrect = CGRectMake ( -, (Self.view.frame.size.height-(Self.view.frame.size.width- +))/2.0f, Self.view.frame.size.width- +, Self.view.frame.size.width- +); //Scan Controls_s

Recently doing a scan code login function, for this I also searched the internet about the implementation of the scan login. When this function was completed, I decided to organize the whole realization, so that I can see it later and also facilitate other programs with similar requirements.To implement a scan login we need to address two issues:1. How do I resolve a privilege security issue without entering a username and password? In other words, ho
