[MPlayer-users] Playback of mp4 files on Windows and the -dr -vo gl:glfinish parameters

[Barb Sterling]

Hello,

I have written an mp4 file viewer using mplayer slave mode that runs on Windows Vista and XP platforms.  It's working great.  The only known issue I have is with parameterizing the call to mplayer correctly at run time.  On some systems, I must specify -dr -vo gl:glfinsh in order for the video output to display.  On other systems providing these parameters causes display problems (which mplayer warns me about).  Initially I thought these additional parameters were required only on Vista systems.  This has proven to not be the case.  I have run into XP systems where I need to supply these parameters and Vista systems that don't work when I supply them.  I even tried basing my runtime decision on whether or not the opengl32.dll was installed or not.  That didn't work reliably either.  

Any ideas/suggestions are appreciated.
