plugins: Add a vaapidecodebin element
Add a "vaapidecodebin" element to vaapi plugins. Child Elements: "vaapidecode ! queue ! vaapipostproc" The Reasons for implementing a new bin element: -- Help to Autoplug Hardware Accelerated Video Postprocessing element in playbin with out any dependency to upstream gstreamer. This is to overcome the *unacceptable* delay in upstream gstreamer to get new features in. Eg: https://bugzilla.gnome.org/show_bug.cgi?id=687182. Also customers using older gstreamer versions (1.2 and 1.4) will get the benefit of autoplugging, hardware accelerated deinterlacing support etc. -- Help to maintain a single thread implementation in vaapidecode. This will result a dead-lock free vaapidecode in most of the cases. More details here: https://bugzilla.gnome.org/show_bug.cgi?id=742605 https://bugzilla.gnome.org/show_bug.cgi?id=745216
