play a video file (.avi) from a command prompt.

[delmer_1]

hey guys, i need to find a program that will allow me to play a .avi file from a command prompt. i found one that will allow you to play sound files(.wav and .mp3) from the command prompt, but i can't seem to locate one that will do video. I really need to find this today if at all possible. I will continue to look, but i was hoping someone here by some strange chance know of a program that will do this.

Help me, please.

Never mind, i found the command line switches to do it with windows media player:

here are teh switches:

/play - plays the desired file
/close - closes media player after playing file

so here is how to do it:

mplay32 /play /close filename

start run c:\windows\cdplayer.exe -play works to play a cd... so try c:\windows\cdplayer.exe - eject ....

I can't check this at the moment, just an idea.

nope that doesn't work, but thanks for the shot...still open to ideas though. gunna try technet next

16 bit assembly program

hey guys: we got it working with windows MEdia player, but not working well. It plays teh video, but then hangs there for a little while before closing. we have tried encoding it different ways, but it still doesnt work. any other suggestions?

[Ruslan]

But why it is needed?
there are few DOS-based multi-media viewers/players, for example,here:
http://www.mpegone.de/
or here:
http://www.multimediaware.com/qv/

About eject - you can find a lot of utils doing that - just type in search "eject.exe" or "eject.zip"...

Hey neat there Cheezemonkey.

Wonder what would happen if I tried that in my HP 8085 Microlab????

i guess i never really did explain why i want this. My boss is writing a program on the AS400 that is used to display real time productivity rates. He also has some video files he wants to play between teh screens that display the data. (Company logo...bright colors (company color is Bright Green) to attract peoples attention so they look at it. it will be displayed on a 42" plasma screen hanging in the cafeteria) being that this is done on the AS400, he has to use command lines, because he can't really write a program that will point and click. he wants it to go from a IBM client access screen (5250 emulation) to pop up this avi file, fullscreen, and then close it and go back to the client access screen until it is time to play the avi file again. the problem is that sometimes it pops up, plays teh movie, fullscreen, and then after it plays, instead of closing, it switches back into a window for a while before it closes. It works with some of teh movies, but not others. they are all encoded with teh same software, the same way. Right now, they are mpeg4. one of them works, one doesn't. I tried installing mediaplayer 9, but it still doesn't work. i will try some of these other dos programs.
