VideoCaptureElement can not select the best video capture parameters

[LazyCuteLion]

VideoCaptureElement set :
DesiredPixelWidth="1920"
DesiredPixelHeight="1080"
FPS="30"
UseYuv="False"
Actual,play on 5fps,my camera have： [YUY2,1920x1080,5FPS]、[MJPG,1920x1080,30FPS]……
I debug "VideoCapturePlayer" and find it the "subType" is "MediaSubType.YUY2" although set UseYuv=Flase.
It should be matched "MediaSubType.MJPG".
