The default scan order of scaling lists are up-right-diagonal
as per hevc specification. Use the newly implemented
uprightdiagonal_to_raster conversion codecparser APIs to
get the the scaling_list values in raster order, which is
what the VA intel driver requires.
Setting the sink to flushing causes gst_vaapi_window_wayland_sync() to
return FALSE which makes gst_vaapi_window_wayland_render() return
FALSE which ends up posting an ERROR message in
gst_vaapisink_show_frame_unlocked(). Solution is to just return TRUE
in the EBUSY case.

First added the function gst_vaapi_video_format_get_best_native(), which
returns the best native format that matches a particular chroma type:
YUV 4:2:0 -> NV12, YUV 4:2:2 -> YUY2, YUV 4:0:0 -> Y800
RGB32 chroma and encoded format map to NV12 too.
That format is used to configure, initially, the surface's pool for the

Improve closure of gaps in frame_num by strictly following and trying
to fill them with previous reference frames. So, they are now tracked
thus avoiding insertion of dummy ("greenish") frames.
If the new picture to be added to the DPB is not a first field, then
it shall be the second field of the previous picture that was added
before.
This removes the need for dpb_find_picture() now that we track the
immediately preceding decoded picture, in decode order.
When a dummy "other-field" is inserted, it is assumed to inherit the
reference flags from the first field, and the sliding window decoded
reference picture marking process is also executed so that corrupted
frames are moved out as early as possible.
While doing so, we also try to output frames that now contain a single
valid field picture, prior to inserting any other picture into the DPB.
Note: this may be superfluous currently based on the fact that dpb_add()
combines the two most recent pairable fields, but this process would be
further simplified later on.
Mark the picture as "corrupted" if it is reconstructed from corrupted
references or if those references are fake, e.g. resulting from lost
frames.
This is useful for notifying the upper layer, or downstream elements,
that the decoded frame may contain artefacts.

This patch fix the auto-plugging problem in gstreamer 1.2 and gstreamer 1.4
Right now there is not a primary ranked parser for vc1 and the demuxers
delivers caps without specifying the profile. This situation is not an issue
for avdec_vc1 but for vaapidecode it is, which refuses to negotiate without a
explicit profile defined in the negotiated caps.
Nonetheless, in gstreamer 1.5 it seems not to be a problem since the
negotiation admits caps subsets try outs.
This patch solves the issue ignoring the profile negotiation in the caps. For
gstreamer < 1.5 the profile string is not handled, so the auto-plugging get
done without the vc1 parser, such as happens in gstreamer 1.5.

Try to identify missing first fields too, thus disregarding any
intermediate gaps in frames. We also assume that we keep the same
field sequence, i.e. if previous frames were in top-field-first
(TFF) order, then so are subsequent frames.
Note that insertion of dummy first fields need to operate in two
steps: (i) create the original first field that the current field
will inherit from, and (ii) submit that field into the DPB prior
to initializing the current (other) field POC values but after any
reference flag was set. i.e. copy reference flags from the child
(other field) to the parent (first field).
https://bugzilla.gnome.org/show_bug.cgi?id=745048
Interlaced H.264 video frames always have two fields to decode and
display. However, in some cases, e.g. packet loss, one of the field
can be missing. This perturbs the reference picture marking process,
whereby the number of references available in DPB no longer matches
the expected value.
This patch adds initial support for missing field within a decoded
frame. The current strategy taken is to find out the nearest field,
by POC value, and with the same parity.
https://bugzilla.gnome.org/show_bug.cgi?id=745048
Try to maintain a "top-field-first" (TFF) flag, even if the H.264 standard
does not mandate it. This will be useful for tracking missing fields, and
also for more correct _split_fields() implementation for frames in the DPB.
Don't try to decode pictures until the first I-frame is received within
the currently active sequence. There is no point is decoding and then
displaying frames with artifacts.
Fix decoding of end_of_seq() NAL unit so that to not submit the current
picture for decoding again. This is pretty vintage code that dates back
before the existing of the whole decoder units machinery.
One issue that could be arising if that code was kept is that we could
have submitted a picture, and subsequently a GstVideoCodec frame, twice.
Once without the decode_only flag set, and once with that flag set. The
end result is that the GstVideoDecoder would release the codec frame
twice, thus releasing stale data.
In short, the piece of code that is removed by this patch is for once
completely obsolete for a while, and secondly error-prone in corner
cases.
If the GOP temporal sequence number (TSN) is interpolated from a valid
PTS, then we need to compensate that PTS corresponding to the start of
GOP with the next picture to be decoded, which shall be an I-frame,
based on its sequence number.

Before pushing a the new frame, the render() method calls sync() to flush the

There is a race condition where g_drm_device_type can be left set to
DRM_DEVICE_RENDERNODES when it shouldn't.
If thread 1 comes in and falls into the last else statement setting up both
RENDERNODES and LEGACY types. And begins to process the first type (RENDERNODES),
it sets g_drm_device_type = RENDERNODES.
Now when thread 2 comes in and sees g_drm_device_type is RENDERNODES, it queues
up that type to be tried but then encounters the lock and has to wait until the
first thread finishes. Once the lock is acquired it will then proceed to ONLY try
RENDERNODES and fail it. But it doesn't try LEGACY. And from then on, all future
attempts will only try RENDERNODES.
