Validate that fps numerator is non-zero so it can be used to calculate
the duration of the B frame.
Also it gst_util_uint64_scale() is used instead of normal arithmetic in
order to aviod overflows, underflows and loss of precision.

Encoders claim to support a whole bunch of input formats but then
just error out if the format is not actually supported, even if
there's a converter in front. This means they're not fit for
autoplugging in encodebin or camerabin yet and therefore should
not have a rank. People can still use them in custom pipelines.

Check earlier if upstream video source has activated the dmabuf-import
io-mode (hack to disappear soon), thus we can avoid the re-assignation of a
new allocator.
Add the method gst_allocator_get_vaapi_image_size() for the
GstVaapiVideoAllocator, which gets the size of the allocated images with the
current video info.
This method replaces the direct call to the allocator's image info when the
pool is configured.
Depends on media, video size is sometimes updated with new allocator.
It leads to dismatch between bufferpool's set size and real allocated buffer size.
In this case, it causes every buffer is freed during release in bufferpool,
which should be reused. This affects performance.

Some invocations of PKG_CHECK_MODULES were intended to be non-fatal if
the package is missing, but action-if-not-found was given as an empty
string which still causes the default action to run, which halts
execution.

Since the upstream of gstreamer-vaapi, the library is not a public shared
object anymore. But the EGL support depended on this dynamic library, so the
EGL support was broken.
This patch removes the dynamic library loading code and instantiates the
EGL display using either X11 or Wayland if available.

In order to register only the available decoders, this patch queries the
created test VA display, which uses the currently used back-end (X11, Wayland,
DRM, …) on the used display device.

Split the vaapidecode to all the supported codecs with the format
vaapi{codec}dec.
vaapidecode is stil registered as a GObject type, but not as a
GStreamer feature, so it can be used internally by vaapidecodebin without
changing its code too much.

Since the elements dependant of the VA video processor are now only registered
if it is available, vaapidecodebin code can be simplified a lot, removing all
the code required to check if the VA video processor was available.

Delay the GstVaapiDisplay instantiating until when changing the state from
READY to PAUSE. In this way the element has more chances to find an already
created GstVaapiDisplay, or a GL context, in the pipeline.
https://bugzilla.gnome.org/show_bug.cgi?id=766206
The function gst_vaapi_create_display_from_gl_context() cretes a
GstVaapiDisplay given a GstGLContext. But it didn't created a GLX VA display
when the GL platform was GLX, but a plain X11 VA display.
This patch fixes that, by querying the GL platform earlier.
https://bugzilla.gnome.org/show_bug.cgi?id=766206
Using the GstContext mechanism, it is possible to find if the pipeline
shares a GstGLContext, even if we are not to negotiating GLTextureUpload
meta. This is interesting because we could negotiate system memory caps
feature, but enable DMABuf if the GstGLContext is EGL with some extensions.

Since the driver checkup is done at registering, there is no need to do it
when changing the element state from NULL to READY. This patch remove this
vmethod from vaapidecode.
Query the GstVaapiDisplay to know if the driver supports video
postprocessing. If does, then register vaapipostproc and vaapidecodebin
elements.
This patch will simplify the design of vaapidecodebin.

Move some of the logic in gst_vaapi_plugin_base_driver_is_whitelisted() to a
new function gst_vaapi_driver_is_whitelisted(), in this way, it can be used
when registering the plugin's feature set with the test VA display.
https://bugzilla.gnome.org/show_bug.cgi?id=724352
This patch tries to instantiate a GstVaapiDisplay when registering the plugin
features, if it fails, no gstreamer-vaapi element is registering.
The purpose of this patch is to avoid a situation where the user has
gstreamer-vaapi installed but their VA-API setup is not functional, which may
lead to unexpected behavior.

There are two main external dependencies that define the feature set of this
plugin: a) the kernel and b) the VA driver
This patch tracks both dependencies, if any of them change, GStreamer will
re-inspect the plugin.
The kernel is tracked through the device files /dev/dri/card*
The VA driver is tracked through the files VA_DRIVERS_PATH/*_drv_video.so,
where VA_DRIVERS_PATH is the one defined in libva package configuration. Also,
the environment variables LIBVA_DRIVERS_PATH and LIBVA_DRIVER_NAME are tracked
since they modify the driver lookup.
Additionally, the environment variable GST_VAAPI_ALL_DRIVERS is tracked too.

This reverts commit 1dbcc8a0e1 and commit
372a03a9e3.
While the dmabuf handle is exported, the derive image must exist, otherwise
the image's VA buffer is invalid, thus the dmabuf handle is never released,
leading into a file descriptors leak.
This is a fix for a regression of previous commit, which updates the filters
only when the property is set, because it is also required to update the
filter when the color balance interface change its values.
In case that sink caps and src caps are same, and no filtering parameter set,
pass-through mode is enabled.
If new filtering parameter is set during playback, it makes it reconfiguring,
so that pass-through mode is changed
In addition, updating filter is performed during reconfiguration, if needed.

A planar(or some other) buffer allocation may fail on the driver, then
the wayland connection becomes invalid, not able to send request or
receive any event. So we need to set up a new wayland connection if
there's an error detected on the cached wl_display.

In order to handle correctly seek and other operations, vaapiencode should
flush all the remaining data from the encoder without pushing it downstream.

To avoid surface-exhausted situation during reverse playback,
drop frames except for key frame.
Also, to avoid the corruption of the parser state, flush() vmethod
doesn't destroy the VA decoder when playing in reverse.

The queue in GstVaapiDecode adds an extra reference to the frames. This patch
unref that extra reference earlier making the code simpler to follow.
https://bugzilla.gnome.org/show_bug.cgi?id=768652
Calling drain() vmethod means "decode any data it can at this point, but that
more data may arrive after". Hence, vaapidecode should check if there is data
in the output adapter and process them, without destroying the decoded picture
buffer (dpb).
Since this operation is done by gst_vaapidecode_internal_flush(), the operation
was refactored into a new function gst_vaapidecode_flush_output_adapter().
https://bugzilla.gnome.org/show_bug.cgi?id=768652
Calling flush() vmethod means "to flush all remaining data from the decoder
without pushing it downstream".
Nonetheless flush() is calling gst_vaapidecode_internal_flush(), which calls
gst_video_decoder_have_frame() if there is still something in the input
adapter, which may push buffers to downstream by calling handle_frame().
This patch changes this behavior by calling gst_vaapidecode_purge() rather
than gst_vaapidecode_internal_flush(), which does what we want: flushes the VA
decoder and releases all the rest of decoded frames.
