According to recommendation from MS, IDXGIOutputDuplication::ReleaseFrame()
needs to be called just before IDXGIOutputDuplication::AcquireNextFrame()
for performance reasons, so that driver can accumulate dirty rects
and update texture at once. But it seems to cause choppy output.
Do release acquired frame immediately once processing done,
like d3d11 implementation does.

Fence data could hold GstD3D12Device directly or indirectly.
Then if it's holding last refcount, the device object will
be released from the device object's internal thread,
and will try join self thread.
Delegates it to other global background thread to avoid
self thread joining.

The output of VP9 and AV1 encoder is a little different from the H264
and H265 encoder, it may contain repeat frames and so the output frame
number may be more than the input. We need to call finish_subframe()
when some frame will be repeated later. So we need to extend the
current prepare_output() virtual function.

Explicitly calls gst_vtenc_pause_output_loop when going PAUSED->READY to make sure GST_PAD_STREAM_LOCK is not taken.
Before this change, a deadlock would occur if pipeline got stopped right after one output buffer was generated by vtenc.

Modify the fix_output_format in vpp to directly generate caps with
negotiated src caps, and we have the correct dma caps negotiation in
fix_output_format function. And thus, we can remove the redundant
negotiation of using function pad_accept_memory in vpp.

The pool currently defaults to performing a layout transition to
VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL, with some special exceptions for
video usages. This may not be a legal transition depending on the usage.
Provide an API to explicitly control the initial image layout.

When implementing NDK media support, it would be useful to also have JNI
implementation in the same binary as NDK media compatibility is lower.
As such, implement a rudimentary vtable system for gstamc-codec and
gstamc-format, and allow choosing the implementation at static_init()
time.
Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/4115>
This allows the implementations to do custom logic behind the hood. For
example, when NDK implementation is added, the entrypoint can chooses to
statically initialize the NDK implementations or the JNI one.

With this patch, the caps is registered in the order of memory features
as: VAMemory, DMABuf then raw caps in linux path, and D3D11Memory then
raw caps in windows path. It helps to prioritize the video memory for all
msdk elements when doing negotiation.

Since DXGI desktop duplication API does not work with Direct3D12 device,

In case of tier 1 decoder, always use reference-only picture to avoid
fixed-size pool limitation and output decoded picture without
copy even for negative rate. Also do not use copy queue for GPU to GPU
copy. Copy queue is specialized for upload/download and may occupy
PCIE bandwidth. Use direct queue as recommended by vendors.

Shader visible descriptors occupy GPU resource and there are hardware
limits. Thus, in order to minimize the amount of shader visible heaps,
only non shader visible descriptor heap (staging) will be held by d3d12memory.
Then converter will copy the staging descriptor to shader visible
descriptor heap per draw.

Zero initialization would have overhead and it's not required
most cases except for textures. Use CREATE_NOT_ZEROED flag

prior read operation.

Conversion will happen when constructed command list is executed,
not by converter element. Thus this object should not map output buffer
with write flag which will result in error if multiple threads
are building commands for the same output target frame.

Add macro which converts picture frame number to suitable timestamp in
nanoseconds for use in V4L2 VB2 buffer lookup. Since multiple codecs do
the same operation and almost all got it wrong, do it in one place so it
can be fixed in one place again, if needed.

The GstMpeg2Picture system_frame_number is guint32, constant 1000 is guint32,
GstV4l2CodecMpeg2Dec *_ref_ts multiplication result is u64 .
```
u64 result = (u32)((u32)system_frame_number * (u32)1000);
```
behaves the same as
```
u64 result = (u32)(((u32)system_frame_number * (u32)1000) & 0xffffffff);
```
so in case `system_frame_number > 4294967295 / 1000`, the `result` will
wrap around. Since the `result` is really used as a cookie used to look
up V4L2 buffers related to the currently decoded frame, this wraparound
leads to visible corruption during MPEG2 decoding. At 30 FPS this occurs
after cca. 40 hours of playback .
Fix this by changing the 1000 from u32 to u64, i.e.:
```
u64 result = (u64)((u32)system_frame_number * (u64)1000ULL);
```
this way, the wraparound is prevented and the correct cookie is used.

The input of the vacompositor may be DMA buffers. And in this case, the input
caps has the format=DMA_DRM, which can not be recognized by base video
aggregator class' find_best_format() function. So we need to override the
update_caps() virtual function.
Also we consider the DMA kind caps in negotiated_src_caps() for output.

VA drivers allocate surfaces given their properties, so there's no need to
provide a buffer size to the VA pool.
Though, the buffer size is provided by the driver, or the canonical size
is used for single planed surfaces.
This patch removes the need to provide a size for the function
gst_va_pool_new_with_config() and adds a helper method to retrieve the surface
size, gst_va_pool_get_buffer_size(). Also change the callers accordingly.
Changes for custom VA pool creation will be addressed in the following commits.

We were previously always querying index 0, and while the number of planes per
buffer will never change, it seems more proper to query the right buffer rather
than always the first one.
This was found while reading strace logs, and wondering why the
V4L2_BUF_FLAG_MAPPED flag was present on all ¬0 indices even though that
happened before VIDIOC_EXPBUF.
