I have the following 1.0 pipeline on a windows box,

gst-launch-1.0 -v videomixer name=mix ! videoconvert ! autovideosink \
videotestsrc pattern=0 ! video/x-raw, framerate=1/1, width=350, height=250 !
\ 
videoconvert !  videobox border-alpha=0 top=-200 left=-50 ! mix. \
multifilesrc location="X:\\test.png" caps="image/png,framerate=1/1" ! pngdec
! videoconvert ! mix.

border-alpha=0 does not seem to do what it is suppose to? can any one tell
if there is an issue with the border-alpha setting for video box.

No matter what i set the property to, (1/0) it always shows a solid
background, i expect to see the background video coming through the border

Thanks
