capture video ok in VLC media player but failed in ActiveX

[my_1998]

Hi,

By vlc media play, I add parameters to video size by 640x480

It did capture a video with 640 x 480

but when I use ActiveX control, it come out to 320x240, the following is my paramter

dshow:// :dshow-vdev="" :dshow-adev="" :dshow-size="320x240"

Any thing wrong with it?

Thanks
