568a62ae1e surfaceproxy: add helper to create a wrapped surface object.
Add new gst_vaapi_surface_proxy_new() helper to wrap a surface into
a proxy. The main use case for that is to convey additional information
at the proxy level that would not be suitable to the plain surface.

8f71f74c5d decoder: h264: add initial support for repeat-first-field (RFF) flag.
Use the SEI pic_timing() message to track and propagate down the repeat
first field (RFF) flag. This is only initial support as there is one
other condition that could induce the RFF flag, which is not handled
yet.

702de9ad2f decoder: propagate MVC metadata ("view-id", head of multiview set).
Add new GstVaapiSurfaceProxy flag FFB, which means "first frame in
bundle", and really expresses the first view component of a multi
view coded frame. e.g. in H.264 MVC, the surface proxy has flag FFB
set if VOIdx = 0.

Likewise, new API is exposed to retrieve the associated "view-id".

5e245ae2c2 surfaceproxy: add copy function.
Add gst_vaapi_surface_proxy_copy() function that creates a new surface
proxy with the same information from the parent proxy, except that the
user-defined destroy notify function is not copied over.

The underlying VA surface is pushed back to the video pool only when
the last reference to the parent surface proxy is released.

15519ebe3d legal: add per-file authorship information.
Credit original authors on a per-file basis as we cannot expect people
to know all country-specific rules, or bother browsing through the git
history.

e66e72e7e3 decoder: add support for video cropping.
Add gst_vaapi_picture_set_crop_rect() helper function to copy the video
cropping information from raw bitstreams to each picture being decoded.
Also add helper function to surface proxy to propagate that information
outside of libgstvaapi. e.g. plug-in elements or standalone applications.

c7dff071c7 surfaceproxy: add more attributes for raw decoding modes.
Add more attributes for raw decoding modes, i.e. directly through the
libgstvaapi helper library. In particular, add presentation timestamp,
duration and a couple of flags (interlaced, TFF, RFF, one-field).

0bd929dfa2 surfaceproxy: drop user-data support from GstVaapiSurfaceProxy.
Drop user-data support from GstVaapiSurfaceProxy. Rather make it explicit
to call some user-provided function when the surface proxy is released.

e65726de8d decoder: drop obsolete functions.
Drop the following functions that are now obsolete:
- gst_vaapi_context_get_surface()
- gst_vaapi_context_put_surface()
- gst_vaapi_context_find_surface_by_id()
- gst_vaapi_surface_proxy_new()
- gst_vaapi_surface_proxy_get_context()
- gst_vaapi_surface_proxy_set_context()
- gst_vaapi_surface_proxy_set_surface()

This is an API change.

e22a863084 decoder: simplify acquisition/release of spare surface.
Introduce gst_vaapi_surface_proxy_new_from_pool() to allocate a new surface
proxy from the context surface pool. This change also makes sure to retain
the parent surface pool in the proxy.

Besides, it was also totally useless to attach/detach parent context to
VA surface each time we acquire/release it. Since the whole context owns
all associated VA surfaces, we can mark this as such only once and for all.

51d028a628 surfaceproxy: drop accessors to obsolete attributes.
Make GstVaapiSurfaceProxy only a thin wrapper around a VA context and a
VA surface. i.e. drop any other attribute like timestamp, duration,
interlaced or top-field-first.

1130a46837 surfaceproxy: port to GstVaapiMiniObject.
GstVaapiSurfaceProxy does not use any particular functionality from
GObject. Actually, it only needs a basic object type with reference
counting.

This is an API and ABI change.

Declaring a function as const enables better optimization of calls

b98d334dce vaapipostproc: get "interlaced" attribute from surface proxy.
Add new "interlaced" attribute to GstVaapiSurfaceProxy. Use this in
vaapipostproc so that to handles cases where bitstream is interlaced
but almost only frame pictures are generated. In this case, we should
not be alternating between top/bottom fields.
