Hi Miquel,<br><br>Take a look at gst-plugins-gl/tests/examples/sdl/sdlshare.c example.<br><br>(note that I have currently only tested it on win32, but I did the stuffs for GLX, so it should work on linux too)<br><br>I think your use case is a little bit more complex because you was talking about threads,<br> maybe because of sdl main loop and glib main loop.<br>So if you succeed then I would like to put your example in gst gl git.<br><br>Regards<br>Julien<br><br><div class="gmail_quote">2009/8/26 Julien Isorce <span dir="ltr"><<a href="mailto:julien.isorce@gmail.com">julien.isorce@gmail.com</a>></span><br> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hello Miquel,<br><br>First, the fact to be able to use the texture from gstgl and use them into your own opengl scene (through your favorite GL framework: clutter, SDL, Qt etc..) is possible (see cluttershare example), interesting and a need for a lot of people.<br><br>Actually, I was waitting for someone that uses SDL.
