 Summary of the bug:resource leaks,handle leaks
 How to reproduce:
         1 OS is Window 7(64BIT)

         3 Test in the through the [Windows Task Manager] to find Handle
 each data play an increasing number 2 (resource leaks,handle leaks)
         4 100% reproduction
         5 Using the FFMPEG version is ffmpeg-20131102-git-
 1fb3b49-Win32-dev and ffmpeg-20131102-git-1fb3b49-Win32-shared
         6 If this modify the code, the problem can solved, but you cannot
 use a multithreaded decoding
                 // disable the thread
                 pCodecCtxVideo->thread_count = 1;
                 // Open codec
                 if(avcodec_open(pCodecCtxVideo, pCodecVideo, NULL)<0) {
