Bug ID: 762986
Summary: videoscale: Add option for navigation events to scale
and respect internal region without borders
Classification: Platform
Product: GStreamer
Version: unspecified
OS: All
Status: NEW
Severity: enhancement
Priority: Normal
Component: gst-plugins-base
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: patcherwork at gmail.com
QA Contact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
The current version of videoscale scales navigation events based on the input
to output ratio. If the output includes borders, the scaling includes the
border area, which causes navigation events to be misaligned compared to the
position of the mouse. This can be illustrated with the following example:
gst-launch-1.0 videotestsrc ! navigationtest !
video/x-raw,width=1024,height=512 ! videoscale ! videoconvert ! ximagesink
If the output window is resized to include borders, moving the mouse over the
output
This patch provides a fix for this behavior, scaling the navigation events
based on only the internal region and not the borders. All events that are
within the borders are discarded.
