We have only one copy of gst_va_base_dec_parent_class inside the
vabasedec, so it can not handle the case when there are multi va
decoders inside one pipeline. The pipeline:
gst-launch-1.0 filesrc location=xxx.h264 ! h264parse \
! vah264dec ! msdkh265enc ! vah265dec ! fakesink
generates a assertion of
"invalid cast from 'GstVaH264Dec' to 'GstH265Decoder"
and gets a crash.
We should keep the parent_class for each decoder type.

Use the object lock for the following fields:
- `bytes`: Written by the `load-bytes` signal unless running; consumed
on start.
- `draw_background`: Read and written by the `draw-background`
property.
- `location`: Read and written by the `location` property and the URI
handler.

VADecPictureParameterBufferAV1.mode_control_fields.bits were filled
twice, overwriting to zeros the first assignation. This patch unifies
both assignations.
Also it makes explicit an enum casting between libva and gstreamer; it
removes the assignation to zero a deprecated parameter; and use an
appropriate assertion.

The previous test was preventing the pad to be in EOS
when the segment position was greater than segment stop.
It ended up consuming all the data before getting in EOS.
Regarding GST_SEEK_FLAG_SEGMENT it seems to be
correctly handled later in the method.

Do not carry over segmentation flags from previous frames. The spec
says in 7.2.10 that the feature data carry over from previous frames
if not updated, but the flags do not.
Consider what would happen if a flag B is to depend on a flag A, and
B carries over as set from another frame. Further consider that A is
now not set in this particular frame. This leads to the invalid state
in which flag B is set but flag A isn't.
This might cause the bitstream to be rejected by accelerators down
the line.
Fix it.

Before creating output duplication interface, call SetThreadDesktop()
with HDESK of the current input desktop in case a desktop switch has
occurred.
This allows d3d11desktopdupsrc to capture Windows User Account Control
(UAC) prompts, which appear on a separate secure desktop. Otherwise
IDXGIOutput1::DuplicateOutput() will return E_ACCESSDENIED and the
element won't produce any frames as long as the UAC screen is active.
Note that in order to access secure desktop the application still has to
run at LOCAL_SYSTEM privileges. For GStreamer applications running with
regular user privileges this change has no effect.

IDXGIOutputDuplication can become invalid for example when there's
desktop switch, resolution change or Windows User Account Control prompt
appears on screen.
When that happens, try to re-create the duplication interface for the
changed output. Note that in the case of UAC prompt this operation will
fail if the GStreamer process doesn't run at LOCAL_SYSTEM privileges. In
such situation the source element won't create any frames as long as the
output is occupied by UAC screen.
In order to enable UAC access to sufficiently privileged GStreamer
processes, call SetThreadDesktop() with the desktop handle that
currently receives user input before creating our output duplication.

The problem is for uploading YUV frames using derived images, is that
derived images imply tiling, so frames are wrongly uploaded.
Though derived for reading might work we cannot know the Intel graphics
generation to validate the caching. Overall, it's safer to disable derived
images for i965.

iHD driver sets a tiled DRM modifier if surface's usage hint is set to
VPP_WRITE. This result in a garbled rendering when using glimagesink.
This patch changes the usage hint to generic if the caps feature is
DMABuf. Either way only iHD driver, so far, uses the usage hint flag.

This MR provides a transform element that leverage ONNX runtime
to run AI inference on a broad range of neural network toolkits, running
on either CPU or GPU. ONNX supports 16 different providers at the
moment, so with ONNX we immediately get support for Nvidia, AMD, Xilinx
and many others.
For the first release, this plugin adds a gstonnxobjectdetector element to
detect objects in video frames. Meta data generated by the model is
attached to the video buffer as a custom GstObjectDetectorMeta meta.
