In most DOS game build packages, there is MPlayer.exe file as a video player.
Perhaps they will be used to play lots of game movies while the game is running.
Could anyone know how they use it?

I am going to play a video while my DOS game is running, too.
First, I placed a execution file of Mplayer in the same folder, and created the start.bat file like this;

mplayer.exe gameintro.mp4
game.exe

Of course, this shows intro videos and then starts the game, but this looks untidy, stupid.
I want to play all movies by the game itself like other old DOS games.
Could anyone know how they implemented this?
Thanks very much for your reading.. 😀
