Dear all,
Could you point us to an example or GST documentation on
how to build a simple plugin element
that has 2 input pads configured in push mode
(1st pad receives video frame and 2nd receives rectangle position to draw over a video frame).
Output should be configured in push mode.
Resulting output is linked to autovideosink and should display the original frame with a rectangle drawn over it.
N.B. We currently use Cairo library to implement drawing.
N.B. We currently achieve similar result with 2/2 I/O plugin element that has one of output pads linked with fakesink. Nevertheless, we observe strange behavior with such setup where frame is corrupt.
Many thanks.
Best regards,
Bogdan
