...ok, I've got this compiling on OSX now, and loading the plugin, but 
but it very quickly unloads because "no 24-bit support"...the relevent 
code here:


   if ((plugmain(FF_INITIALISE, NULL, 0)).ivalue == FF_FAIL){
     error("plugin %s: init failed", name);
     return NULL;
   }

//  plugmain(FF_DEINITIALISE,NULL,0);
   if ((plugmain(FF_GETPLUGINCAPS, (LPVOID)FF_CAP_32BITVIDEO, 0)).ivalue 
== FF_TRUE){
     if(can_rgba)*can_rgba=1;
   } else {
     if(can_rgba)*can_rgba=0;
     if ((plugmain(FF_GETPLUGINCAPS, (LPVOID)FF_CAP_24BITVIDEO, 
0)).ivalue != FF_TRUE){
       error("plugin %s: no %dbit support", name, 24);

       plugmain(FF_DEINITIALISE, NULL, 0);
       return NULL;
     }
   }

...is different than what I was using in a standalone OSX FF-host 
loader:

     if (pFreeFrameMain!=NULL) {

         pFreeFrameMain(FF_DEINITIALISE,NULL,0);

         if 
((DWORD)pFreeFrameMain(FF_GETPLUGINCAPS,(void*)2,0)==FF_TRUE) {
                 pVideoInfo->bitDepth=2;
         } else if 
((DWORD)pFreeFrameMain(FF_GETPLUGINCAPS,(void*)1,0)==FF_TRUE) {
                 pVideoInfo->bitDepth=1;
         } else if 
((DWORD)pFreeFrameMain(FF_GETPLUGINCAPS,(void*)0,0)==FF_TRUE) {
                 pVideoInfo->bitDepth=0;
         } else {
                 assert(FALSE);
                 pVideoInfo->bitDepth=2;
         }	

         pFreeFrameMain(FF_INITIALISE,pVideoInfo,0);
	
     }

...so, having not really peered into the logic too much, are you trying 
have it only load if it does RGBA?
