AVICOMPRESSOPTIONS opts;
AVICOMPRESSOPTIONS FAR * aopts[1] = {&opts};
PAVISTREAM ps = NULL,

AVISaveOptions(NULL, 0, 1, &ps, (LPAVICOMPRESSOPTIONS FAR *) &aopts))

翻译后
var
ps:IAVISTREAM;
opts:TAVICOMPRESSOPTIONS;
aoptsAVICOMPRESSOPTIONS;
//指针型 ^TAVICOMPRESSOPTIONS;

begin

aopts:=@opts;
AVISaveOptions(null,0,1,ps,aopts);
老是报类型转换错误

请高手指教

aopts 是数组指针，所以应该是指针的指针。

何必搞那么多呢，你想搞视频方面的东西是不是，到http://www.delphi-jedi.org/Jedi:APILIBRARY
去下载vfw.pas就可以了
