I'm trying to write a script that plays(displays) avis, mpgs and jpgs. The jpegs display correctly but the motion files display a black screen. The script sample in the manual doesn't work if I copy and paste. Any help would be greatly appreciated.

media_play("movie.mpg",NULL,100);
media_play("movie.avi",NULL,100);

Yes, but when I go to run the routine, the window just goes blank. It does a successful compile but hangs on the code you suggested. Heres the code:
#include <litec.h>
#include <default.c>
#include <acknex.h>

function Main()
{
Sound_vol = 100;
media_play("CTST.mpg",NULL,100);
}

If I change the file to a jpeg, it runs fine. It just hangs on movie files.

Is there a difference if I'm running MS VISTA?
Do I need to #include another class?
Is the function Main() ok or should I try another call?


Any other suggestions would be greatly appeciated

When a still image works your code is ok. But for playing a movie on a PC, the CODEC for that movie format must be installed on the PC.

Windows comes with standard codecs so normally you should be able to play mpg, but maybe that mpg file has some special format that is not supported.

Good point,
If I play the mpg in Windows media player or other software, it does play normally. I tried other versions of the movie (avi, etc.) but to no avail. I'm wondering if lite-C is not accessing the CODEC library on my computer. I'm running VISTA and I know 3DGS has some issues running under VISTA. Also, the .c file is in the same folder as the mpgs. Does that make a difference? And finally, I'm running a trial version (A7)

Hmm, when it plays in Media player I normally would assume that it also plays in 3DGS because 3DGS uses the media player for the media_play function. I dont think Vista can be the reason, 3DGS has no issues with Vista. Can you try some other movies in other formats?

Yes, I tried avi(different codecs), wmv, different resolutions(320x200) and different video modes(5,6,7).
I thought I read on the installation instructions of A7 that vista users should keep the files out of \program files and instead put them under \user. Thats why I mentioned vista.
Any other ideas?

not sure if you have it working yet but here is what i think might fix it. are you getting any errors when you run it, because i see no need for "Sound_vol = 100". also not to make out that you are stupid but is the mpg in the same folder as the *.c file you are running. i found that it only runs from the same directory. also for somereason see if media_loop works, when trying to code a similar thing today i found that loop worked (i needed it to loop anyway).

I had the same problem. I found out, "Well this worked for me" that the media_play only played media of a certain resolution and also if you didn't lock the FPS to around 60 they where choppy.
