* gst_ffmpegviddec_frame() is the only caller of gst_ffmpegviddec_video_frame()
and has the same signature. Just move the checks into a single function and
use that.
* Make it clear which frames are the input and output ones in
gst_ffmpegviddec_video_frame() to make issues like the one fixed in the previous
commit more obvious.

The FORCE_KEYFRAME frame which has GST_VIDEO_CODEC_FRAME_FLAG_FORCE_KEYFRAME
bit set should be the sync point. So we should let it be an IDR frame to begin
a new GOP, rather than just promote it to an I frame.

__STDC_NO_ATOMICS doesn't seem to exist. In fact the only compiler
I've found that sets any of those is msvc, but it sets
__STDC_NO_ATOMICS__, not __STDC_NO_ATOMICS.
__STDC_NO_ATOMICS__ is the one documented by C11 standard.

This fixes the code regarding dropping "ghost frames", that is to say input
frames which ended up not producing any decoded frame.
The iteration itself makes sense.. but it was stopping at the "input" frame and
not the decoded frame we just got back.
When dealing with I-frame codecs, ffmpeg will decode frames in separate frames,
so there is no guarantee that they are decoding in order.
Fixes playback issues with such codecs

Set the P and B frame qp to I frame value to avoid generating delta
QP between different frame types. For ICQ and QVBR modes, we can
only set the qpi value, so the qpp and qpb values should be set to
the same value as the qpi.

There's nothing requiring <= 64 channels except for getting the reorder
map and creating a channel mixing matrix, but those won't be possible to
call anyway as channel positions can only express up to 64 channels.

Certain V4L2 fourccs don't (yet) have DRM counter parts, in which case
we can't create DMA_DRM caps for them. This is usually the case for
specific tilings, which are represented as modifiers for DMA formats.
While using these tilings is generally preferable - because of e.g.
lower memory usage - it can result in additional conversion steps when
interacting with DMA based APIs such as GL, Vulkan or KMS. In such cases
using a DMA compatible format usually ends up being the better option.
Before the addition of DMA_DRM caps, this was what playbin3 ended up
requesting in various cases - e.g. prefering NV12 over NV12_4L4 - but
the addition of DMA_DRM caps seems to confuse the selection logic.
As a simple and quite robust solution, assume that peers supporting
DMA_DRM caps always prefer these and reorder the caps accordingly.
In the future we plan to have a translation layer for cases where
there is a matching fourcc+modifier pair for a V4L2 fourcc, ensuring
optimal results.

Doing it in gst_play_new() means that bindings that directly call
g_object_new() with the GType wouldn't end up initializing both.
This affects at least the Python and GJS bindings.
gst_init() is nonetheless only called from gst_play_new() once because
calling it from class_init would likely lead to problems as that's
called from somewhere in the middle of GObject.

Don't add an extra ref if non-floating as that ref will never be
unreffed.
gst_bin_add() is transfer floating (alias to transfer none).
Fixes a leak when a non-floating ref was provided as a return value in
the request-aux-sender signal.

Use of VK_PIPELINE_STAGE_2_ALL_COMMANDS_BIT instead of
specific VK_PIPELINE_STAGE_2_VIDEO_DECODE_BIT_KHR
Fix for VUID-vkCmdPipelineBarrier2-srcStageMask-03849
pDependencyInfo->pImageMemoryBarriers[0].srcStageMask
(VK_PIPELINE_STAGE_2_VIDEO_DECODE_BIT_KHR) is not compatible with
the queue family properties
(VK_QUEUE_GRAPHICS_BIT|VK_QUEUE_COMPUTE_BIT|VK_QUEUE_TRANSFER_BIT|
VK_QUEUE_SPARSE_BINDING_BIT|VK_QUEUE_PROTECTED_BIT) of this
command buffer. The Vulkan spec states: The srcStageMask member
of any element of the pMemoryBarriers, pBufferMemoryBarriers, or
pImageMemoryBarriers members of pDependencyInfo must only
include pipeline stages valid for the queue family that was
used to create the command pool that commandBuffer was allocated
from (
https://www.khronos.org/registry/vulkan/specs/1.3-extensions/
html/vkspec.html#VUID-vkCmdPipelineBarrier2-srcStageMask-03849)
The frame barrier should use a compatible srcStageMask for all
the queues.
Remove reset_pipeline_stage_mask as it is redundant

Add pitch tests with different forward and backward playback rates.
Those tests depend on the libSoundTouch version to validate the buffers
checksums. The actual version uses libSoundTouch 2.3.2, use the
`--force-fallback-for=soundtouch` meson option to build using the same
version.
