glImagesink changing windows?
Locked
 
|
I have an application that needs to change the window that the video is being displayed on using the glimagesink.
The way I acomplish this with all of the other video sinks is I send a null to the xoverlay interface and then send
the new window pointer once I create the new window. This works fine on xvimagesink, directdrawimagesink, and most others.
But with the glimage sink the video never transfers to the new window.
I have looked through the gl code but I am new to opengl and could easily be missing something.
Can anyone give me sugestions on how to fix this?
Or am I doing this the wrong way?
Thanks
Levi

IIRC glimagesink reparents its window into the xoverlay one. If you send a null window it's likely that when you set a new window it tries to reparent it to null. I'm not sure if this reparenting thing is right, other sinks create a new context with the new window. Anyway, if what I'm guessing is right, glimagesink should at least check for the xid to be non null.

Apparently it does that check. ------------------------------------------------------------------------------ Register Now for Creativity and Technology (CaT), June 3rd, NYC.

Hi,
2009/5/29 Levi Pope <[hidden email]>
Could you write a mininal test to reproduce the problem ? You want to call gst_x_overlay_set_xwindow_id several times right ? The first call is working ? I am sure you have read this page, but in case not: http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstxoverlay.html#gst-x-overlay-prepare-xwindow-id Anyway if it works with other video sinks then this is certainly a bug. You can file a bug here: http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer Julien

Thanks for looking into that for me.
Another thing I was looking at is the navigation interface. I think xv is the only other sink that implements it. I modified glimagesink to do it for my testing I was wondering if that was going To be added any time soon?
Again thanks for the help.
