<DIV>To Zhang Xiang:</DIV>
<DIV> 我想testprog里的程序已经很清楚了,你问的其实是一个C++的问题.</DIV>
<DIV> 程序的运行流程我也没有弄太清楚,但是我可以讲讲我个人的理解.</DIV>
<DIV> 程序里应该说有两个线程,doeventloop()和play().doeventloop其实就是调用了singlestep()来while()了一个死循环,它始终保证一个schedule一直在执行,这个应该说是程序的主循环.你说的dogetnextframe()等程序其实是一个间接的重入,</DIV>
<DIV> play()-->afterplaying()-->play()</DIV>
<DIV>然后反复的循环,这中间就调用了getnextframe()等很多你看得晕乎乎的程序.</DIV>
<DIV> 其实你根本不用管这些程序的中间的执行过程是怎样的,你只要能理解你需要的testprog的大概流程,然后做你需要的修改.最重要的一点,就是你应该知道你的stream是如何write_data()到程序中,而在客户端又是怎么被read_data()的.</DIV>

<DIV>Hello!</DIV>
<DIV>I am Zhang Xiang, graduate student from Zhe Jiang University,China. I’m confused about how the function SingleStep() works. Specifically speaking, when there is a video connection request from remote PC, how does SingleStep() handle this request and call other functions such as DeliverFrame(), doGetNextframe(), to deliver video stream which is encoded in H.264 form?</DIV>
<DIV> Thanks!!</DIV>
<DIV>Best wishes!</DIV>
<DIV> yours Xiang </DIV></FONT></SPAN>
