plugins: add new base object, store display in there. Introduce a new GstVaapiPluginBase object that will contain all common data structures and perform all common tasks. First step is to have a single place to hold VA displays. While we are at it, also make sure to store and subsequently release the appropriate debug category for the subclasses.

plugins: rework set_context() vmethod definition In bug 757598 was added the set_context() vmethod chain up in GstVaapiPluginBase. But it is buggy, since the parent_class address is assigned to the last element which called gst_vaapi_plugin_base_class_init(). No error has shown up since none of the element's base classes redefined set_context() vmethod from GstElement, so always the correct function was called. Still this code is wrong and this patch make it right. Since set_context() is the same code, a macro is used to implement that code in all the gst-vaapi elements. https://bugzilla.gnome.org/show_bug.cgi?id=765368

plugins: base: manage pad-specific data in a single struct Define a struct (GstVaapiPadPrivate) to encapsulate the pad-specific data (i.e. buffer pool, allocator, info, caps, etc.). Add an interface to retrieve the data struct for a given pad. Finally, update the base plugin to use the data struct throughout the implementation. This will enable us to easily extend the base plugin in the future to allow for N-to-1 pad subclasses (e.g. overlay/ composite).

plugins: rework set_context() vmethod definition In bug 757598 was added the set_context() vmethod chain up in GstVaapiPluginBase. But it is buggy, since the parent_class address is assigned to the last element which called gst_vaapi_plugin_base_class_init(). No error has shown up since none of the element's base classes redefined set_context() vmethod from GstElement, so always the correct function was called. Still this code is wrong and this patch make it right. Since set_context() is the same code, a macro is used to implement that code in all the gst-vaapi elements. https://bugzilla.gnome.org/show_bug.cgi?id=765368

If this GstGLContext not found either then, only the VAAPI decoders and the VAAPI post-processor, will try to instantiate a new GstGLContext. If a valid GstGLContext is received, then a new GstVaapiDisplay will be instantiated with the platform, API and windowing specified by the instantiated GstGLContext.

GstCaps *
plugins: Add more check for allowed raw caps. The gst_vaapi_plugin_base_get_allowed_raw_caps is used for both sink pad and src pad, which cause some bugs. For sink pad, we need to verify vaPutImage() while for the src pad we need to verify vaGetImage(). For vaapidecoderXXX kind of plugins, the case is more complex. We need to verify whether the decoded result(in some surface, NV12 format most of the time) can be vaGetImage to some raw image format. Add more check to fix all these problems. https://gitlab.freedesktop.org/gstreamer/gstreamer-vaapi/issues/123 Signed-off-by: He Junyan <junyan.he@hotmail.com>
