First off, does your test app work in Windows?

I downloaded your test app and used winetricks to install xvid.

I then ran WINEDEBUG=msvideo,driver wine codec.exe, and this is a partial log
of what I see:

trace:msvideo:ICOpen (VIDC,XVID,0x00000000)
trace:driver:OpenDriver (L"VIDC.XVID", L"drivers32", 0x0033fe08);
trace:driver:DRIVER_GetLibName registry: L"VIDC.XVID", L"drivers32", 0x33fbb6,
522
trace:driver:DRIVER_TryOpenDriver32 (L"xvidvfw.dll", 0033FE08);
(snip)
trace:driver:DRIVER_TryOpenDriver32 (L"xvidvfw.dll", 0033FE08);
trace:driver:DRIVER_SendMessage Before call32 proc=0x10006d20 drvrID=00000000
hDrv=0x1287d8 wMsg=0003 p1=00000000 p2=0033fe08
trace:driver:DRIVER_SendMessage After  call32 proc=0x10006d20 drvrID=00000000
hDrv=0x1287d8 wMsg=0003 p1=00000000 p2=0033fe08 => 00000000
trace:driver:DRIVER_AddToList DRV_OPEN failed on driver 0x1287d8

The After line (the next to the last line) indicates that the return value from
this DRIVER_SendMessage call is NULL, which winmm thinks is a failure:

233         lpNewDrv->d.d32.dwDriverID = DRIVER_SendMessage(lpNewDrv, DRV_OPEN,
lParam1, lParam2);
234 
235         if (lpNewDrv->d.d32.dwDriverID == 0)
236         {
237             TRACE("DRV_OPEN failed on driver %p\n", lpNewDrv);
238             return FALSE;
239         }

So either this is a xvid bug, or this initialization process in Wine is flawed.
