This counter is incremented once for every segment, meaning it would
e.g. overflow after 24 days when using 1ms segments. Once that happens,
completely wrong positions are reported and invalid memory is handed out
for writing/reading the next segments.
As the affected variables are unfortunately part of the public API of
the struct, a second set of variables is added together with accessor
functions and both variables are kept in sync for backwards
compatibility.
All existing users of the two variables are moved to the new ones but
external code might still run into the overflow.
This also slightly breaks API as external code updating the variables
will have no effect anymore but the only known user of this is
pulsesink.

Making it possible to properly handle compositors that have those
properties as doubles and handle antialiasing.
Internally we were handling those values as doubles in framepositioner,
so expose new properties so user can set values as doubles also.
This changes the GESFramePositionMeta API but we are still on time for 1.24

This can be used to store informational messages, errors or
warnings which can later be shown to the user in gst-inspect-1.0,
which can be useful for plugins that expose elements dynamically
based on external libraries or hardware capabilities.
Status messages can then provide an indication as to why a
plugin doesn't have any elements listed, for example.
Plus unit test to make sure code paths are exercised a little.

- gst_analytics_cls_mtd_get_length() return a gsize, this type dicated index
type for gst_analytics_cls_mtd_get_quark() and
gst_analytics_cls_mtd_get_level().

- Support HTTP redirect codes (301,302,307,308) on response to GET.
"Location" field is extracted and used for following GET and POST.
- Notify caller a redirect took place using return value
- log source and destination url on redirect

Today when using the `splitmuxsrc` on a collection of files named as:
```
item0.mkv
item1.mkv
item2.mkv
[...]
item10.mkv
item11.mkv
[...]
```
You will get a continuous stream made in the order of:
```
item0.mkv -> item1.mkv -> item10.mkv -> item11.mkv -> [...]
```
You can fix this by having smarter names of the items:
```
item000.mkv
item001.mkv
item002.mkv
[...]
item010.mkv
item011.mkv
[...]
```
Will get you:
```
item000.mkv -> item001.mkv -> item003.mkv -> item004.mkv -> [...]
```
But, we could also "fix" the former case by using natural ordering when
comparing the files in gstsplitutils.c.

This allows user to be in control of when scaling happens in the pipeline.
It can be plugged as an effect and scaling will be forced to happen in
the effect instead of in the compositor.
Without this, it would not be possible for users to, for example,
crop a video source before scaling to the target source size.

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 we finish a frame, we pass a size which semantic can easily be confused.
Improve the documentation to clarify that the parameter size is the amount of
input data being consumed and, if set, the output_buffer size can differ.

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.

- GstAnalyticRelationMeta is a base class for analytics
meta. It's able to store analytics results (GstAnalyticRelatableMtd)
and describe the relation between each analysis results.
- GstAnalysisRelationMeta also contain an algorithm able to explore
analysis results relation using a bfs.
- Relation(edge) between analysis results (vertice) are stored in an adjacency-matrix
that allow to quickly identify if two analysis results are related and by
which relation they related. It also work for indirect relation
and can provide the path of analysis results by which two
analysis results are related.
- One allocation per buffer to store analysis results. Here we rely on
the application to guess how much space will be required to store all
analysis results. This is something that could be improved
significantly but it's a starting point.
- Define common analysis results, classification, object-detection,
tracking that are subclass of GstAnalyticRelatableMtd. The also
provide exemple of how to extend GstAnalyticRelatableMtd to have them
benefit for the mechanim to express relation with other analysis
results.

Instead of guessing the DRM format and modifier, pass a DRM video info to
gst_va_dmabuf_memories_setup().
Still, it checks for the DRM parameters in DRM info, if they are not available,
as in the case of V4L2 buffers, the part of the video info is used.
This is an API breakage, but since the plugin is still in stage, it's still
allowed.

Formatters might call "loaded" from the `gessrc` streaming thread
meaning that the `->formatters` field need to be protected.
Several other APIs are called from gesbasedemux, in some radom
thread, so we should ensure that this is all MT. safe, and the API
makes it simple.

Adds list of formats that should be used by element in needs to passthrough
video. It contains the full list of video format plus DMA_DRM format
and will be extended in the future as needed. This patches includes 3 new
symbols:
- GST_VIDEO_FORMATS_ANY_STR
- GST_VIDEO_FORMATS_ANY
- gst_video_formats_any()
The last one can be used by bindings or for code that prefers having
GstVideoFormat values instead of strings.

While the suspend modes NONE and PAUSED provided a low startup latency
for connecting clients they did not ensure that streams started on
fresh data.
With this property we can maintain the low startup latency of those
suspend modes while also ensuring that a stream starts on a key unit.
Furthermore, by modifying the value of a new property,
ensure-keyunit-on-start-timeout, it is possible to accept a keyunit of
a certain age but discard it if too much time has passed and instead
force a new keyunit.
