qtmux: use trun with multiple entries in more cases

The only case where we definitely need to write a new trun is when the
data_offset value does not match the end of the list of entries.
Needing multiple trun atoms is required when interleaving multiple
streams together.

All other cases can be covered by adding more entries to the existing
trun atom.

libs: context: use queried value for attrib

Attribute's value should use returned value from get_attribute for
VAConfigAttribRTFormat, since VAProfileHEVCMain10, in AMD Mesa Gallium,
can process either VA_RT_FORMAT_420 and VA_RT_FORMAT_420_10, which isn't
considered in gstreamer-vaapi design, where encoder's src pads will
expose only 4:2:0 color formats but no 4:2:0 10bit. So, this is a workaround
for this issue while new vah265enc is released.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2784>

playbin3: Move gapless to uridecodebin3

This was the intention from the start, just took me a few years *cough* to
actually implement it properly.

Gapless is handled by re-using as much as possible the same decoders and sinks
if present, and only pre-rolling switching at the sources level (with buffering
if/when needed).

In order to enable "gapless" playback, the "next" uri should be set at any time
between the moment the `about-to-finish` signal is emitted and the moment the
current play item is done. Previously this could only be done with the signal
emission.

This new implementation also allows "Instantaneous URI switching". This allows a
much faster way of switching playback entries while re-using as many elements as
possible. To enable this set `instant-uri` property to TRUE, the default being
FALSE.

multiqueue: Handle gapless input

When dealing with gapless input (i.e. streams with changing group-id in
GST_EVENT_STREAM_START), we need to take into account the elapsed
running-time (if applicable) in order to properly calculate levels and output
time. Without doing this all incoming data from future groups would be
considered as being "late" and would be consumed immediately.

This does **NOT** modify the actual segment and buffer times, and is only used
internally.

decodebin3: Allow re-using inputs

DecodebinInput (and their backing parsebin or identity) are no longer released
when the corresponding sinkpad is unlinked, but when it's released.

The parsebin element will be resetted:
* If incoming caps are incompatible (was the case before)
* Or when unlinking and it was previously pull-based

This opens the way to use decodebin3 with changing inputs (i.e. gapless)

uridecodebin3: use urisourcebin parse-streams property

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2784>

urisourcebin: Improve buffering handling

Introduce the option to have the streams be parsed with `parsebin` for
compatible sources (i.e. which are eligible for buffering in the same way as
before this commit).

By parsing the inputs directly, this allows more accurate buffering control:
* Instead of relying on potential bitrate information coming from somewhere
* and *without* being linked downstream

If `parse-streams` is activated and the stream is eligible for buffering, then a
`multiqueue` will be used on the output of `parsebin` in order to handle the
buffering.

parsebin: avoid bogus processing

If a parsebin pad is already exposed, don't try to rename it or cause extra
processing which isn't needed

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2784>

decodebin3: Avoid parsebin usage if not needed

If the incoming streams are already parsed, there is no need to add yet-another
parsebin to process it *IF* that stream is compatible with a decoder or the
decodebin3 output caps.

This only applies if all the following conditions are met:
* The incoming stream can *NOT* do pull-based scheduling
* The incoming stream provides a `GstStream` and `GstStreamCollection`
* The caps are compatible with either the decodebin3 output caps or a decoder
  input

If all those conditions are met, a identity element is used instead of a
parsebin element and the same code paths are taken.

* Remove never used `pending_stream` field from DecodebinInputStream
* When unblocking a given DecodebinInput (i.e. wrapping a parsebin), also make
  sure that other parsebins from the same GstStreamCollection are unblocked

* ChildSrcPadInfo is created for each source element source pad
* ChildSrcPadInfo contains the chain of optional elements specific to that
  pad (ex: typefind)
* A ChildSrcPadInfo links to one or more OutputSlot, which contain what is
  specific to the output (i.e. optional buffering and ghostpad)
* No longer use GObject {set|get}_data() functions to store those structures and
  instead make them explicit
* Pass those structures around explicitely in each function/callback

urisourcebin: Remove pending pad handling

This was needed to support the legacy handling of changing streams (add new
pads, send EOS and remove old pads).

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2784>

urisourcebin: Only expose pads once activation has completed

The following problem could happen:
* Thread 1 : urisourcebin gets activated from READY->PAUSED
* Thread 2 : some element causes a pad to be added to urisourcebin , which gets
linked downstream, which decides to activate upstream to pull-based.
  * That requires "activating" the pads from PUSH to NONE, and then from NONE to PULL
* Thread 1 : the base class state change handlers checks if all pads are
activated

The issue is that since going form PUSH to PULL requires going through NONE,
there is a window during which:
* Thread 1 : The pad was set to NONE (before being set to PULL)
* Thread 2 : The base class activates that pad (to PUSH)
* Thread 1 : The attempt to "activate" to PULL fails (silently or not)

This is very racy, so in order to avoid that, we make sure that we only add pads
once the transition from READY->PAUSED in the parent classes is done.

urisourcebin: Only allow streams-aware adaptive demuxer

This reverts commit fcad4cc646a23e4e621ec5e8485958ab78d98090.

This was wrong is so many ways.

* The memcmp was badly used (it should use == 0 to check the data is identical,
  and not != 0)
* There was no boundary checks on the present stream section_data when passing
  it to memcmp.
* The return value should have been TRUE (i.e. we have done all checks, none of
  them failed, therefore the section has been seen before)
* stream->section_data would *always* be NULL if the section had already been

wavparse: Do not run all typefinders for all output

In order to figure out if the "raw" audio contained within the wav
container is actually DTS, wavparse calls the typefinder helper
except that means it runs all typefinders.

Since it only cares about checking for DTS, we should only run the
audio/x-dts typefinder (if present). Commit 858e516 did not really
fix things.

Use the new type helper with the caps to fix this.

rtspsrc: Consistently set seqnums on events

Set udpsrc seqnums on all events sent to the udpsrc's, and before
forwarding events out of rtspsrc set the latest seek seqnum on them if
any.

Also produce a consistent seqnum in rtspsrc from the very beginning.

rtspsrc: Make segment event writable before overriding the seqnum and use the proper API to do so

rtspsrc: Intercept and handle events when using no manager too

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3409>

rtspsrc: Don't blindly copy over sticky events from manager pad to external source pad

This would get around the code that modifies some events when they go
through the ghost pad's proxypad. Instead go via the event function.

rtspsrc: Don't make udpsrc segment events writable just to retrieve their seqnum

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3409>

rtspsrc: Reset EOS flag also on FLUSH_STOP and not only on ssrc-active

Also don't bother not sending EOS if EOS was sent already:
gst_pad_push_event() takes care of that for us already.

pbutils: Fix vp9 mime mapping when caps when no chroma-site.

It's possible to have 4:2:0 chroma format without chroma-site in caps, but it
isn't validated by the current code. This patch fixes it.

videodecoder: Consider having output data when the subclass drops a frame

The subclass might drop a frame for QoS reasons (e.g. vpxdec) and if all
frames are dropped because of that it wouldn't make sense to post an
error message on EOS.

h264/5timestamper: provide a workaround for h264/5parse producing pts=NONE buffers

A workaround for

cudaconvertscale, cudascale: Add "add-borders" property and support 8bits RGB planar formats

Adding "add-borders" property which is identical to that of
videoscale and this will be enabled by default.
And adding RGBP/BGRP/GBR/GBRA format support.

cuda: Rewrite colorspace/rescale object

Rewriting GstCudaConverter object, since the old implementation was not
well organized and it's hard to add new features.
Moreover, the conversion operations were not very optimized.

Major change of this implementation:
* Remove redundant intermediate conversion operations such as
  any RGB -> ARGB(64) conversion or any YUV -> Y444 (or 16bits Y444).
  That's not required most of cases. The only required case is
  converting 24bits (such as RGB/BGR) packed format to 32bits format
  because CUDA texture object does not support sampling 24bits format
* Use normalized sample fetching (i.e., [0, 1] range float value)
  and also normalized coordinates system for CUDA texture.
  It's consistent with the other graphics APIs such as Direct3D
  and OpenGL, that makes sampling operations much easier.
* Support a kind of viewport and adopt math for colorspace conversion
  from GstD3D11 implementation

cudaupload,cudadownload: Add support for planar 8bits RGB formats

Defines RGBP, BGRP, and GBR formats, which have the same memory
layout as already supported Y444. And defines GBRA format as well
which needs just one additional alpha plane

cuda: Add convertscale element

GstCudaConverter object can do colorspace conversion and scale at once.
Adding new element "cudaconvertscale" to do that, this can
save unnecessary GPU operation if colorspace conversion and
rescale is required for given input stream format.

Most of codes are taken from d3d11convert element

typefindhelper: Use the new GstTypeFind * API

typefindhelper: Introduce a new API for working with a GstTypeFind *

Introduce a new API that can return a GstTypeFind * with helper functions
and data set around buffer data.

While at it, drop factory field from GstTypeFindBufHelper. While it was
useful for logging, it was not passed through function arguments and keeping
it for logging would require an additional API increasing the API surface
and making it harder to use.

mpdparser: Fix missing baseURL query

When no initializationURL or mediaURL, return baseURL that also
contains original URI query if available. This fixes a problem
where URI query was being omitted in the HTTP requests.

mpdparser: Be consistent about returning duplicated URL

Instead of returning a "const gchar" or a "gchar" that should not be freed, always
return a duplicated string as those functions were used together with g_strdup anyway.

This is needed to prepare support for returning modified strings in next commit.
