Two elements in the luminance quantization table were wrong. So,
gst_jpeg_get_default_quantization_tables() now reconstructs tables
in zig-zag order from the standard ones (Tables K.1 and K.2).
... instead of having them pre-calculated. This saves around 1.5 KB
of data in the DSO but requires gst_jpeg_get_default_huffman_tables()
to do more work. Though, the client application may have to call that
function at most once, only.
This is not useful in practice but for raw performance evaluation when
the sink is invoked with display=drm sync=false. fakesink could also be
used though.
If vaapisink is in the GStreamer pipeline, then we shall allocate a
unique GstVaapiDisplay and propagate it upstream. i.e. subsequent
queries from vaapidecode shall get a valid answer from vaapisink.
Move display types from gstvaapipluginutil.* to gstvaapidisplay.* so that
we could simplify characterization of a GstVaapiDisplay. Also rename "auto"
type to "any", and add a "display-type" attribute.
This improves display name comparisons by always allocating a valid display
name. This also helps to disambiguate lookups by name in the global display
cache, should a new backend be implemented.
The vdeo buffer creation routines shall actually be internal to gstreamer-vaapi
plugin elements. So deprecate any explicit creation routines that are not the
new *_typed_new*() variants.
Introduce new typed constructors internal to gstreamer-vaapi plugin elements.
This avoids duplication of code, and makes it possible to further implement
generic video buffer creation routines that automatically map to base or GLX
variants.
If GLX window was created from a foreign Display, then that same Display shall
be used for subsequent glXMakeCurrent(). This means that gl_create_context()
will now use the same Display that the parent, if available.
This fixes cluttersink with the Intel GenX VA driver.
vaapisink is now built with support for multiple display types, whenever
they are enabled. The new "display" attribute is used to select a particular
renderer.
This flag is obsolete. It was meant to explicitly enable/disable VA/GLX API
support, or fallback to TFP+FBO if this API is not found. Now, we check for
the VA/GLX API by default if --enable-glx is set. If this API is not found,
we now default to use TFP+FBO.
Note: TFP+FBO, i.e. using vaPutSurface() is now also a deprecated usage and
will be removed in the future. If GLX rendering is requested, then the VA/GLX
API shall be used as it covers most usages. e.g. AMD driver can't render to
an X pixmap yet.
GStreamer -base plugins >= 0.10.31 are now required, so the checks for
new APIs like GstXOverlay::set_window_handle() and ::set_render_rectangle()
are no longer necessary.
