plugins: add compat layer for GstVideoContext. Add thin compatibility layer for the deprecated GstVideoContext API. For GStreamer API >= 1.2, this involves the following two functions: - gst_vaapi_video_context_prepare(): queries if a context is already set in the pipeline ; - gst_vaapi_video_context_propagate(): propagates the newly-created context to the rest of the pipeline. https://bugzilla.gnome.org/show_bug.cgi?id=703235 Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>

videocontext: support "gst.vaapi.app.Display" context Through "gst.vaapi.app.Display" context, users can set their own VADisplay and native display of their backend. Attributes: - display : pointer of VADisplay - x11-display : pointer of X11 display (Display *), if they're using. This patch creates GstVaapidisplayX11 if information provided through "gst.vaapi.app.Display" https://bugzilla.gnome.org/show_bug.cgi?id=766704

vaapivideocontext: add gst_vaapi_video_context_set_display() This function set the display to an already created context. This function is going to be used later. Also, gst_vaapi_video_context_new_with_display() now uses this function. Signed-off-by: Víctor Manuel Jáquez Leal <victorx.jaquez@intel.com> https://bugzilla.gnome.org/show_bug.cgi?id=757598

plugins: check if display is set in sync Since the context messages are sync'ed, the display assignation happens in the same thread, hence we can know if the display was found or not as soon we call for it. In order to take advantage of it, gst_vaapi_video_context_prepare() receives, as a new parameter, the address of the plugin's display, and reports back if the display was found and set.

plugins: add gst_vaapi_plugin_base_find_gl_context() Using the GstContext mechanism, it is possible to find if the pipeline shares a GstGLContext, even if we are not to negotiating GLTextureUpload meta. This is interesting because we could negotiate system memory caps feature, but enable DMABuf if the GstGLContext is EGL with some extensions. https://bugzilla.gnome.org/show_bug.cgi?id=766206
