[XviD-users] wmplayer and xvid: not working after install

[Daniel Donnelly]

Hi,

For some reason xvid.org forums are not accepting joiners, so maybe xvid-users 
know my symptoms....

I've recently built and installed the xvid codec on WinXP and Window Media 
Player 10 is not using the codec (usual "can't find right codec" error dialog) 
to play an xvid video.  Previously I had a divx codec installed and WMP did 
use that to play video I encoded with REVEL, which uses xvid.  What needs to 
be done, or what other info do you need?

Also, I plan to insert these videos into a PPT presentation and I've had some 
problems with random codecs not being supported through PowerPoint.  How can 
this be if PPT uses the same list of codecs everything else does.  Of course, 
WMP isn't recognizing some codecs either.  I could be imagining that, but some 
videos that would play under WMP would crash PPT - I though PPT uses a WMP 
plugin (?)  There's not a lot of information on how PPT works at that level 
that I can find.  This is a whole other problem though from the first, but 
just in case anyone would recognize it.

On xvid installation: everything went as it should AFAICT.  xvidcore.dll and 
xvidvfw.dll are in system32, instructions that were packaged with the source 
code were followed.  I've also checked that the problem still occurs with the 
dll's in the video file's directory.

I did have a binary distribution of xvid installed that also did not work with 
WMP, in the same manner.  Before attempting to install xvid and test, I 
removed all other related codecs (all divx, that xvid, etc.) with the windows 
device manager in addition to their uninstall utilities if they came with one.

More Details:
The video file is an AVI made by REVEL by examples/reveltest.cpp.  Here is the 
interesting part: I have videos made by someone else that windows say are 
encoded with xvid (properties), and that also say they're xvid.  WMP plays one 
this file perfectly.  To ensure it was *the* xvid codec that I installed I 
tried removing xvid through the device manager (and that didn't quite work 
either...), so instead I just deleted xvidcore/xvidvfw.dll from the system32 
folder and made sure they're not reappearing.  The xvid video still plays!  
That convinces me that it's not a problem with REVEL or the avi it outputs.  
What's up with that?  I haven't yet tried removing MS MPEG-4 codec (maybe 
there's a conflict?), so I'll try that next.

Thanks!
