011f9bd6cb surface: add support for dma_buf imports.
Add new gst_vaapi_surface_new_with_dma_buf_handle() helper function
to allow for creating VA surfaces from a foreign DRM PRIME fd. The
resulting VA surface owns the supplied buffer handle.

dd37fc4999 surface: add initial support for foreign buffer imports.
Add gst_vaapi_surface_new_from_buffer_proxy() helper function to
create a VA surface from an external buffer provided throug the
new GstVaapiBufferProxy object.

f3c58d4ef4 surface: add support for GEM buffer exports.
Add support for GEM buffer exports. This will only work with VA drivers
based off libdrm, e.g. the Intel HD Graphics VA driver. This is needed
to support interop with EGL and the "Desktop" GL specification. Indeed,
the EXT_image_dma_buf_import extension is not going to be supported in
Desktop GL, due to the lack of support for GL_TEXTURE_EXTERNAL_OES targets
there.

This is useful for implementing VA/EGL interop with legacy Mesa stacks,
in Desktop OpenGL context.

073d6d59e1 surface: add support for dma_buf exports.
Use the new VA buffer export APIs to allow for a VA surface to be
exposed as a plain PRIME fd. This is in view to simplifying interop
with EGL or OpenCL for instance.

250260cc36 Add abstraction for exported VA buffers.
The VA buffer export APIs work for a particular lifetime starting from
vaAcquireBufferHandle() and ending with vaReleaseBufferHandle(). As such,
it could be much more convenient to support implicit releases by simply
having a refcount reaching zero.

96ce1bc761 videopool: add optional flags for surface pool allocation.
Reword surface pool allocation helpers so that to allow for a simple
form, e.g. gst_vaapi_surface_pool_new(format, width, height); and a
somewhat more elaborated/flexible form with optional allocation flags
and precise GstVideoInfo specification.

This is an API/ABI change, and SONAME version needs to be bumped.

f5af9d150e window: add toplevel display indirection for visualid and colormap.

the best suitable window visual id and colormap. This is an indirection in

desired Visual, i.e. now use a visual id instead of a Visual object.

ff0a237458 window: add generic helper to create windows.
Add a new generic helper function gst_vaapi_window_new() to create
a window without having the caller to check for the display type
himself. i.e. internally, there is now a GstVaapiDisplayClass hook
to create windows, and the actual backend implementation fills it in.
Add new generic helper functions gst_vaapi_texture_new_wrapped()

This is a simplification in view to supporting EGL.

7d5d3e8640 display: refine the meaning of display type.
Make gst_vaapi_display_get_display_type() return the actual VA display
type. Conversely, add a gst_vaapi_display_get_class_type() function to
return the type of the GstVaapiDisplay instance. The former is used to
identify the display server onto which the application is running, and
the latter to identify the original object class.

93418ed5ee texture: add generic helper to create textures.
Add new generic helper functions gst_vaapi_texture_new_wrapped()
and gst_vaapi_texture_new() to create a texture without having

internally, there is now a GstVaapiDisplayClass hook to create
textures, and the actual backend implementation fills it in.

2101685b7d texture: move to core libgstvaapi base library.
GstVaapiTexture is a generic abstraction that could be moved to the
core libgstvaapi library. While doing this, no extra dependency needs
to be added. This means that a GstVaapitextureClass is now available
for any specific code that needs to be added, e.g. creation of the
underlying GL texture objects, or backend dependent ways to upload
a surface to the texture object.

Generic OpenGL data types (GLuint, GLenum) are also replaced with a
plain guint.

1799b362a3 texture: drop support for VA/GLX interfaces.
The VA/GLX interfaces are obsolete. They used to exist for XvBA, and
ease of use, but they had other caveats to deal with. It's now better
to move on to legacy mode, whereby VA/GLX interop is two be provided
through (i) X11 Pixmap, and (ii) other modern means of buffer sharing.

0a108653f2 texture: add support for cropping rectangle during transfer.
The gst_vaapi_texture_put_surface() function is missing a crop_rect
argument that would be used during transfer for cropping the source
surface to the desired dimensions.

Note: from a user point-of-view, he should create the GstVaapiTexture
object with the cropped size. That's the default behaviour in software
decoding pipelines that we need to cope with.

This is an API/ABI change, and SONAME version needs to be bumped.

Add new gst_vaapi_surface_new_full() helper function that allocates
VA surface from a GstVideoInfo template in argument. Additional flags
may include ways to
- allocate linear storage (GST_VAAPI_SURFACE_ALLOC_FLAG_LINEAR_STORAGE) ;
- allocate with fixed strides (GST_VAPI_SURFACE_ALLOC_FLAG_FIXED_STRIDES) ;
- allocate with fixed offsets (GST_VAAPI_SURFACE_ALLOC_FLAG_FIXED_OFFSETS).

Really report sample aspect ratio (SAR) as present, and make it match

really make sure VUI parameter aspect_ratio_info_present_flag is set
to TRUE and that the indication from aspect_ratio_idc is Extended_SAR.
