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.

5444ab44d2 jpeg: add support for multiscan images.
Add support for images with multiple scans per frame. The Huffman table
can be updated before SOS, and thus possibly requiring multiple uploads
of Huffman tables to the VA driver. So, the latter must be able to cope
with multiple VA buffers of type 'huffman-table' and with the correct
sequential order.

1fff3a44dd decoder: fix memory leak when processing interlaced pictures.
Fix memory leak when processing interlaced pictures and that occurs
because the first field, represented as a GstVideoCodecFrame, never
gets released. i.e. when the picture is completed, this is generally
the case when the second field is successfully decoded, we need to
propagate the GstVideoCodecFrame of the first field to the original
GstVideoDecoder so that it could reclaim memory.

Otherwise, we keep accumulating the first fields into GstVideoDecoder
private frames list until the end-of-stream is reached. The frames
are eventually released there, but too late, i.e. too much memory
may have been consumed.

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.

8c2d9bcd24 decoder: maintain decoded frames as GstVideoCodecFrame objects.
Maintain decoded surfaces as GstVideoCodecFrame objects instead of
GstVaapiSurfaceProxy objects. The latter will tend to be reduced to
the strict minimum: a context and a surface.

79b45a43d1 Do not forward declare enums.
Forward declaring enums is not allowed by the C standard and aborts
compilation if the header file is included in a C++ project.

dba174906a libs: declare _get_type() functions as const.
Declaring a function as const enables better optimization of calls
to the function.

75538bbc9b decoder: use POC to maintain the DPB.
Introduce a POC field in GstVaapiPicture so that to store simpler sequential
numbers. A signed 32-bit integer should be enough for 1 year of continuous
video streaming at 60 Hz.

Use this new POC value to maintain the DPB, instead of 64-bit timestamps.
This also aligns with H.264 that will be migrated to GstVaapiDpb infrastructure.

7a9410f826 mpeg2: add support for interlaced streams.
Pictures are submitted to the HW for rendering only when both fields
are decoded or current picture is a full frame.

b56ac16224 decoder: add first-field flag to picture.
Add first-field (FF) flag to GstVaapiPicture, thus not requiring is_first_field
member in each decoder. Rather, when a GstVaapiPicture is created, it is considered
as the first field. Any subsequent allocated field will become the second field.

195a61fa02 decoder: allow pictures to be cloned for field decoding.
Add gst_vaapi_picture_new_field() function that clones a picture, while
preserving the parent picture surface. i.e. the surface proxy reference
count is increased and other fields copied as is. Besides, the picture
is reset into a "non-output" mode.

c27385aa8d decoder: rework picture field flags.
Add top-field-first (TFF) and interlaced flags to GstVaapiPicture so they
could be propagated to the surface proxy when it is pushed for rendering.
Besides, top and bottom fields are now expressed with picture structure flags
from GstVaapiSurfaceRenderFlags.

a7ec623279 decoder: fix semantics of SKIPPED pictures.
If GstVaapiPicture has flag SKIPPED set, this means gst_vaapi_picture_output()
will not push the underlying surface for rendering. Besides, VC-1 skipped P-frame
has nothing to do with rendering. This only means that the currently decoded
picture is just a copy of its reference picture.

4a46b5d6c4 decoder: retain proxy surface until the GstVaapiPicture is destroyed.
Keep a valid reference to the proxy in GstVaapiPicture so that frames
marked as "used for reference" could be kept during the lifetime of the
picture. i.e. don't release them too soon as they could be re-used right
away.

e5d12e8853 decoder: rework the internal VA objects API.
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.
