// play_psfswpvr is a two threaded application.  
// the play_psfswpvr.c contains the main thread, which utilizes the hardware demux.
// play_vdemux.c contains a thread that utilize a software demux
// the hardware thread starts a playback from (for all demux tasks) first
// Upon swiching command, all hardware demux tasks' output shall be suspended 
// while the demux module is still alive.  The main thread is suspended.
// The software demux is created on main_vdemux thread. the output of the software
// demux is then connected to the video and audio decoders and start playback from
// software demux's source (assume only one for now).
