[gst-devel] Querying GL context pixel format

[Andrey Nechypurenko]

Hi,

The glupload/Qt texture sharing example works now. 
Thanks to all of you answered to my questions.

I submit the Bug 600797 with attached sources. Now GL plugin 
developers can decide whether to include this example in 
gst-plugins-gl/tests/examples/qt ;-) .


Regards,
Andrey.

have you checked that the sdlshare or cluttershare examples are working on your win32 environment ?
(works on mine)
