hlsdemux2: Fix crash on live playlist with single entry

If there is a single entry, we would end up computing a minimum distance of 0,
and would therefore read entries from after the segment array

nvdec: Fix for HEVC decoding when coded resolution is larger than display resolution

As documented in the SDK header, we should set coded width/height

instead of display resolution

gstinfo: remove the vasprintf fallback

We are always building our printf implementation, even when
GST_DEBUG is disabled, since we are exposing api (gst_print*)
that's dependant on our printf behavior.

We don't need to keep __gst_info_fallback_vasprintf around anymore.

additional device compatibility check so that only NVIDIA GPU
associated d3d11 device can be configured in the element.

cuda: Remove GST_CUDA_HAS_D3D define from header

... and fix d3d11 specific enum type name

GST_CUDA_HAS_D3D is a build time define which indicates whether
GstD3D11 library is available or not, but DirectX SDK headers
must be available on the build system already.

Expose Direct3D related symbols if the build target is Windows

meson: Build with -Wl,-z,nodelete to prevent unloading of dynamic libraries and plugins

GLib made the unfortunate decision to prevent libgobject from ever being
unloaded, which means that now any library which registers a static type
can't ever be unloaded either (and any library that depends on those,
ad nauseam).

va: Remove from plugin cache.

GstVA is not currently build by CI, because libva version is lower
than expected. So, the gstva library is not build, thus some symbols
aren't documented, breaking the documentation CI.

To move things forward, let's just remove temporarly the va plugins
from cache. While we decide on how to update the libva package in
the CI.

docs: Generate libgstva GI and pkg-config.

Currently libgstva is only exposed internally to gst-plugins-bad. No

neither gobject-introspection files.

adaptivedemux2: Always check bitrate in live

When advancing fragment in live, it's normal to return
GST_FLOW_EOS when playing at the live edge of the available
fragments. In that case, we still want to adjust bitrate
dynamically.

Fixes issue with dashdemux2 where the current bitrate of
each adaptation set is changed to the lowest one when
updating the mpd for a live stream.

meson: use python.get_install_dir() to find the pygobject overrides dir

Instead of trying to hardcode site-packages paths for different platforms
just use python.get_install_dir() from meson and let it deal with the rest.
Also no longer try to import pygobject, which would otherwise not be
required at build time.

python.get_install_dir() was at the beginning broken on Windows, but
that was fixed in 0.60 via https://github.com/mesonbuild/meson/pull/9156
and since ges now requires >0.60 this can be ignored.

This change was motivated by the install path being wrong under MSYS2, where
the unix install layout is used and the detection code not taking that into
account.

This MR is a continuation of https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/230

webrtcbin: fix picking available payload types

When picking an available payload type, we need to pick one that is
available across all media.

The previous code, when multiple media were present, looked at the first one,
noticed it had pt 96 as the media pt, then simply looked at the next media,
noticed it didn't, and decided 96 was available.

Instead, check if the pt is used by any of the media, if it is, decide
it is not available and go to the next pt. I'm fairly sure that was the
original intent.

dashdemux2: Preserve current representation on live manifest updates

When updating a manifest during live playback, preserve the current

because it couldn't be matched, trigger a caps change and new

rtpjitterbuffer: Change RTX timer availability checks to assertions

It's impossible to end up in the corresponding code without a timer for

rtpjitterbuffer: Only unschedule timers for late packets if they're not RTX packets and only once

Timers for RTX packets are dealt with later in update_rtx_timers(), and
timers for non-RTX packets would potentially also be unscheduled a
second time from there so avoid that.

Also don't shadow the timer variable from the outer scope but instead
make use of it directly.

rtsp-server: stream: Don't loop forever if binding to the multicast address fails

The address/port is pre-defined by the caller of the function, so
retrying is only going to loop forever.

Ideally the multicast address should be checked after allocating but
this doesn't happen currently, so it's better to error out cleanly then
to loop forever trying the same address.

gst_init: Initialize static plugins just before dynamic plugins

All plugins needs to be initialized after `gst_initialized = TRUE;`
otherwise they could complain that gst_init() has not been called.

This can happen if the data inside the packets is incomplete without the
seqnums being discontinuous because of ULPFEC being used.

d3d11memory: Fix GstAllocator::mem_copy() implementation

We were checking possible bind flags for the DXGI format
of the source texture but that's never applied to
the destination texture desc.

Just use the already configured bind (and misc) flags of source texture
for the destination texture allocation without additional check.

bin: Don't propagate state change errors of elements in locked state

Theoretically having elements in locked state should not have any effect
at all when the surrounding bin is doing state changes. However
previously a state change error of a locked element would cause the
bin's state change to also fail, which is clearly not intended.

State change failures of locked elements are to be handled by whoever
set the element to locked state. By always returning them here it is
impossible for the owner of the element to handle state change failures
gracefully without potentially affecting the whole pipeline's state
changes.

Non-failure returns are still returned as-is as the distinction between
ASYNC/NO_PREROLL/SUCCESS has big consequences on the state changes of
the bin and overall pipeline. Theoretically SUCCESS should also be
returned in all cases but I can't estimate the effects this would have
on the overall pipeline.

avfvideosrc: Fix wrong default framerate value

Current default G_MAXINT is not a correct value under any circumstances.
This creates an issue with screen capture, during which we currently do
not get any framerate info causing G_MAXINT to show up, where elements
downstream can possibly misbehave - for example, `vtenc` causes
a kernel panic.
Replace with 30/1 to avoid such scenarios.

jpegdecoder: return the real error of decode_scan and decode_frame.

The current handle_frame() does not return the real error that happens
in decode_scan and decode_frame, which makes the pipeline continue with
the error and may trigger asserting later.

We also return the error when decode_quant_table or decode_huffman_table
fails.

d3d11videosink: Add display-format property

For instance, BGRA format should be used for Direct2D interop.
