bfd8d294b4 [122/906] better implementation of gst_gl_display_set_window_id for win32. (change the window of the current wglcontext instead of reinit everything, and so avoid some problems about opengl objects that could be init in the previous wglcontext and so no usable in the newer wglcontext, it what the case for the first texture) This newer implementation has not been made yet on linux

f1744c26ec [061/906] First SVN commit. This commit is a hack to make git-rebase work 2014-03-15 18:36:18 +01:00
Tim-Philipp Müller
1d59ab7b37 [060/906] * gst-libs/gst/gl/gstglbuffer.c: (gst_gl_buffer_format_from_video_format): Fix compiler warning if there are video format enums gstglbuffer doesn't know about yet. * gst-libs/gst/gl/gstgldisplay.c: (gst_gl_display_upload_texture_rectangle), (gst_gl_display_draw_texture): Fix printf format for 64-bit integers. 2014-03-15 18:36:18 +01:00

7fbd185eb5 [058/906] * gst-libs/gst/gl/Makefile.am: The library needs to link against libgstvideo-0.10. * gst/gl/Makefile.am: The plugin does not (I think) need to link against GL or libgstvideo, since our new gstreamer GL library already does that, but it does need to link against our brand-new libgstgl-0.10. 2014-03-15 18:36:18 +01:00
David Schleef
0a3e152339 [056/906] * configure.ac: Readd pre-pkgconfig OpenGL detection, since pkgconfig requires Mesa from git master. * gst/gl/glimagesink.c: * gst/gl/gstopengl.c: Move debug category initialization to element. * gst-libs/gst/gl/Makefile.am: * gst-libs/gst/gl/gstglfilter.c: * gst-libs/gst/gl/gstglfilter.h: * gst/gl/gstglfilter.c: * gst/gl/gstglfilter.h: Move glfilter to library. * pkgconfig/gstreamer-plugins-gl.pc.in: Add gstreamer-base-0.10 as a requirement. * po/en.po: Update. 2014-03-15 18:36:18 +01:00

Make glfilterexample visually interesting. Add support for various formats to downloading. Fix a few places where we leak GL state to other elements (bad, but hard to prevent). 2014-03-15 18:36:18 +01:00
