Hi,
I'm writing an app that implement some digit ptz function. I'm using the
videocrop element for doing that, but i have some issue with that. If I get a
live view from v4l2src in 25 fps, and applying the a top/right/bottom/left
property in sequence sometimes the picture goes to "jumping". I guess the
problem is the fps rate, the videocrop element crops the top and right side of
the picture, but the next frame is arrived and the bottom and left side will be
cropped from that, and the previous frame will show up incorrectly (in my
view).
I tried padblock berfore the videocrop, applying the properties, then unblock,
but it will be unusable at low framerate.
Is there any way to set the 4 property in one?
Regards,
Tibor
