I'd like to overlay widget on camera captured image renderd by gstreamer.
I tried to set X_OVERLAY of mfw_v4lsink element to application widget by gst_x_overlay_set_render_rectangle.
Captured image overlayed on the widget for video display.
then, I add another widget which overlayed on the video display widget.
However, I could not operate the addtional widget.
This problem didn't occur in using ximagesink.
Does anyone know about this?
