Adding nvautogpu{h264,h265}enc class which will accept upstream logical
GPU device object (GstCudaContext or GstD3D11Device) instead of
using pre-assigned GPU instance.

glupload: Fix caps query with no filter

If no filter caps are provided with a caps query, always
generate a full set of all caps from all upload methods,
not just the configured one. This is needed to handle
renegotiation when dealing with raw sysmem caps - as the upload
method might accept raw sysmem caps, but only the raw data
uploader adds those to the caps query.

This reverts commit f3292dc1561a8d62812c3f1a2bb3de5c5bb6a807.

Only the raw data uploader should add sysmem caps to the
actual caps query, because we want them to be at the
lowest priority. If upstream does select to send raw
caps, then the correct upload method will still
be chosen because the accept_caps implementation

hlsdemux2: Improve media playlist updates

  initial fragment search and avoids issues when streams at activated at a much
  later time.

hlsdemux2: No longer re-add segments from before the playlist

When updating playlists, there is a possibility that the playlists don't
perfectly align, but the last entry of the previous playlist is *just* before
the first entry of the new playlist.

In those cases, we still can transfer the timing information from one playlist
to another, but we do not want to return that segment as being the matching one.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2679>

hlsdemux2: Use variant stream as support for synchronizing playlists

When matching playlists, there is a possibility that rendition streams will not
have been updated in time (for example because that stream started later, or
playback was paused). This would cause several playback failures and seeking
failures.

In order to still fall back on our feet, attempt to synchronize that rendition
playlist against the current variant playlist. This will attempt to match the
stream time using SN/DNS/PDT/...

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2679>

adaptivedemux2: Fix SNAP seek handling

* Since only flushing seeks are allowed, the "current" position is always the
  global output position (and not "some" stream current position).

* In terms of figuring out to which stream to "snap" to, we can send it to any
  selected stream. Removes the requirement of this function to a specific output
  pad.

hlsdemux2: Fix position tracking

Remove the "pending advance" hack and instead rely on the base stream current
position to track our position (instead of a potentially NULL "current
segment").

Also ensure the media playlists are always refreshed with valid stream time,
even if there is no current segment.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2679>

hlsdemux2: Add a new method to synchronize two media playlist

This allows transfering the stream time of the playlist to an updated

adaptivedemux2: Initialize and use stream start/current position

The stream start and current position would be properly set when seeking or
activating a stream after playback started. But it would never be properly
initialized.

Set it to NONE initially to indicate to subclasses that no position has been
tracked yet. This will allow them to detect initial stream usage.

Futhermore, once the initial streams setup is done, make sure that it is set to
a valid initial value:
* The minimum stream time in live
* Or else the period start

with fourcc specified.

From jpeg decoder to the allocator, which creates the surfaces,

It follows the same logic as the others video decoders in the library but.
as JPEG are independet images, there's no need to handle a DBP so no need

Gallium drivers historically have reported strange dmabuf sizes, from always
zero to the whole frame (multiple fds). The simplest solution is to use lseek
SEEK_END to get the prime descriptor size.

Also the allocator raises a warning if both values differ in order to report
it to driver.

va: allocator: Fix translation of VADRMPRIMESurfaceDescriptor

VADRMPRIMESurfaceDescriptor structure describes the offsets from the
point of view of the specific handle (DMABuf). While GstVideoInfo
(and the meta) describes offsets from the point of the view of the
GstBuffer, an aggregate of all the GstMemory (1 per handle).

This changes combined with [Mesa Fix](https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/16813)
fixes decoding failure with AMD driver.

d3d11: Revert staging buffer pool implementation

The staging buffer pool implementation was added to improve
throughput performance since we can avoid per-frame
CPU copy operation via staging texture but it turned out that
we can not make it thread safe. See
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1182

bin: Fix race conditions in tests

The latency messages are non-deterministic and can arrive before/after
async-done or during state-changes as they are posted by e.g. sinks from
their streaming thread but bins are finishing asynchronous state changes
from a secondary helper thread.

To solve this, expect latency messages at any time and assert that we
receive one at some point during the test.

h265parse: Fix uninitialized width and height when update src caps.

The commit b90d0274 introduces uninitialized width and height when we
consider to change the "pixel-aspect-ratio" for some interlaced stream.
We need to check the resolution in the src caps, and if no resolution
info found, there is no need to consider the aspect ratio.

d3d11compositor: Performance optimization

Removing glvideomixer-like nuance (it was initially referenced)
and rewriting element since it's not an optimal design at all
from performance point of view.

* Remove wrapper bin (and internal conversion/upload/download elements)
  which will waste CPU/GPU resources. Conversion/blending can be done by the
  d3d11compositor element at once.
* Add support YUV blending without RGB conversion.
  The RGB <-> YUV conversion is completely unnecessary since YUV textures
  support blending as well.
* Remove complicated blending operation properties since it's hard
  to use from application point of view. Instead, adding "operator" property
  like what compositor element does.

gstwaylandsink: Add rotate-method property

Similar to and inspired by glimagesink and gtkglsink.

Using the Wayland buffer transform API allows to offload
rotate operations to the Wayland compositor. This can have
several advantages:
 - The Wayland compositor may be able to use hardware plane
   capabilities to do the rotation.
 - In case of pre-rotated content on rotated outputs the
   rotations may equal out, potentially allowing the
   compositor to use hardware planes even if they don't
   support rotate operations.

avviddec, video.c, h265parse: Workaround for broken field-based interlaced encoders

Some encoders (e.g. Makito) have H265 field-based interlacing, but then
also specify an 1:2 pixel aspect ratio. That makes it kind-of work with
decoders that don't properly support field-based decoding, but makes us
end up with the wrong aspect ratio if we implement everything properly.
As a workaround, detect 1:2 pixel aspect ratio for field-based
interlacing, and check if making that 1:1 would make the new display
aspect ratio common. In that case, we override it with 1:1.
