Fakesink and GstNavigation

[Nicolas-2]

Hello,

I created a "playbin2" and a "fakesink" (I render the video in an evas
image)
Now my problem is that "fakesink" has no "GstNavigation".
How can I do to implement the "GstNavigation" to "Fakesink" ?

Thank you in advance
Sincerely,
Nicolas.

That is the wrong approach. You rather want to implement a evasvideosink and
implement the navigation iface there.

Hello,

Thanks for your response.
Ok, I have the gstreamer plugin and i implemented the navigation interface.

My problem is I don't know what to put in the function:

static void evas_video_sink_navigation_send_event (GstNavigation *
navigation, GstStructure * structure)

What is require in this function ?

Thanks in advance,
Nicolas.

Here's one example:

http://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/sys/xvimage/xvimagesink.c#n2730

The xvimagesink implementation is about as complex as it gets, because
the xvimagesink supports scaling and offsetting of the video into the
output surface. The navigation_send_event implementation reverses those
operations, so it takes mouse clicks in the window coordinates, and
converts it back to a mouse click coordinate within the original video.
