You can either open a file known to be encoded with XviD with GSpot, which will tell you if there's a decoder installed, or open the file with a media player such as Windows Media Player and see if it plays with video. Or just install the latest XviD codec.

start->system config -> software...

should be one of the last entries because of the 'X' :D

I want know this with a program and in other's, so I think these ideas of you can't do that.:confused:

if it's installed, it's installed... point!!

if you can't use it - that's another question ;)

try virtual dub...

open up the compression config and have a look at all listed codecs - do see xvid listed as a vfw codec?? but why shouldn't xvid be there, presumed you have correctly installed xvid... you see.

If you need to know whether xvid is installed correctly, you only need to check %SystemDirectory% for xvid.ax, and if you want to get technical, check that the registry is pointing to xvid (HKCR\CLSID\{64697678-0000-0010-8000-00AA00389B71}\ InprocServer32\@ = something with xvid.ax, technically xvid.ax can be anywhere but it's almost always in the system32 folder), and that HKCR\CLSID\{083863F1-70DE-11d0-BD40-00A0C911CE86}\ InprocServer32\{64697678-0000-0010-8000-00AA00389B71} exists, and its CLSID value points back to itself.

If all you want to do is to find out if a video is decodable, which you really should do because xvid's not the only decoder out there, you have to render a graph and check whether it worked or not.

in other words... just follow CWR03's first suggestion and don't bother with things you are not so familiar with :)
