Does intelcam.sys support Motion JPG format(ex:FCC_FORMAT_MJPG)?
I can't find enough information in document.
MJPG option is showed in Amcap but can not preview with MJPG format.
KS_DATARANGE_VIDEO structure below

Thanks for any help or hint.

Do you have an MJPG codec installed? There isn't one built-in.

Device can preview with MJPG when I use Video Class Driver.
I think MJPG codec is installed.

Forget say that, I can't adopt Video Class Driver for some reason.

Software MJPEG comes with XP.
