Hi guys! As far as I know, AVI, MPG, WMV are supported, right? What else are supported by 3DGS itself? Are there some ways to make 3DGS support more video types?

you can use third party plugins to support that kind of thing.

Actual matter is not the file extension, it's the video container. Anything that is supported by DirectShow(i.e. anything you can play in mediaplayer) is therotically supported by the engine. You need the required codecs though.

Thanks! Do you mean that if the user doesn't have any encoder player, I even can not play AVI in 3DGS? So if I know the user has a real player, 3DGS even can play a rm video? And I want to make sure that 3DGS can play avi, wmv and mpg just using Lite-C. Are all of others need plug-in?

No, not plugins, direct show compatible encoders. They should be preinstalled at least for wmv and avi on every windows installation. I am not absolutely shure about mpg, but I guess this should be preinstalled with windows too.

Mpg should also be fine if you have windows xp, vista, or windows 7.
