[GEM-dev] just an other videoV4L bugfix

[Georg Holzmann]

Hallo again!

in constructor of videoV4l.cpp, m_continue_thread is not initialized, 
and because the first device is started automatically, it will be 
stopped (pthread_join) and it crashes if you use Gem together with PDP 
... (doesn't crash if you only use GEM ...)

anyway, this fixes the problem:
(videoV4L.cpp, line 53)

--------8<------------8<-------------

videoV4L :: videoV4L(int format) : video(format){
#ifdef HAVE_VIDEO4LINUX
   if (!m_width)m_width=64;
   if (!m_height)m_height=64;
   m_capturing=false;
   m_channel=COMPOSITEIN;
   m_norm=VIDEO_MODE_AUTO;
   m_devicenum=DEVICENO;
   m_continue_thread = false;
   post("video4linux");
#endif /* HAVE_VIDEO4LINUX */
}
