Move GstVaapiVideoMeta from core libgstvaapi decoding library to the
actual plugin elements. That's only useful there. Also inline reference
counting code from GstVaapiMiniObject.
Make sure libgstvaapi core decoding library doesn't include un-needed
dependencies. So, move out GstVaapiVideoConverterGLX to plugins instead.
Besides, even if the vaapisink element is not used, we are bound to have
a correctly populated GstSurfaceBuffer from vaapidecode.
Also clean-up the file along the way.
Make GstVaapiVideoBuffer a simple wrapper for video meta. This buffer is
no longer necessary but for compatibility with GStreamer 0.10 APIs or users
expecting a GstSurfaceBuffer like Clutter.
Introduce a new GstVaapiDecoderFrame that is just a list of decoder units
(GstVaapiDecoderUnit objects) that constitute a frame. This object is just
an extension to GstVideoCodecFrame for VA decoder purposes. It is available
as the user-data member element.
This is a libgstvaapi internal object.
Introduce GstVaapiDecoderUnit which represents a fragment of the source
stream to be decoded. For instance, a decode-unit will be a NAL unit for
H.264 streams, an EBDU for VC-1 streams, and a video packet for MPEG-2
streams.
This is a libgstvaapi internal object.
Introduce a new reference counted object that is very lightweight and
also provides flags and user-data functionalities. Initialization and
finalization times are reduced by up to a factor 5x vs GstMiniObject
from GStreamer 0.10 stack.
This is a libgstvaapi internal object.
This fixes symbol clashes between the gst-vaapi built-in codecparsers/
library and the system-provided one, mainly used by videoparses/. Now,
only symbols with the gst_vaapi_* prefix will be exported, if they are
not marked as "hidden" to libgstvaapi.
GStreamer codecparsers-based decoders are the only supported decoders now.
Though, FFmpeg decoders are still available in gstreamer-vaapi 0.3.x series.
The new API simplifies a lot reference counting and makes it more
flexible for future additions/changes. The GstVaapiCodecInfo is
also gone. Rather, new helper macros are provided to allocate
picture, slice and quantization matrix parameter buffers.
This new interface allows for upstream and downstream display sharing
that works in both static and dynamic pipelines.
