3f7f9145d2 playback: Remove USE_PLAYBIN3 registration override
This was only introduced as a convenience for testing playbin3 instead of
playbin2.

Now that playbin3 is (explicitely) default in many cases, we should not do this
hack anymore

1baa36c14a volume: Expose the volume-full-range as another property
In https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5063
the range of volume value has changed which breaks backward compatibility
when  using a GstDirectControlBinding which is not acceptable. To avoid
breaking compatibility add the feature of allowing the full range  using
another property with the full range. When using that full range, the
value of the `volume` property might end up being out of its valid
range but we do not really have a good solution for that.

489f310881 urisourcebin: Handle legacy pad replacements from parsebin
When dealing with demuxers which aren't streams-aware, we need to handle the
old-school "stream replacement" dance from `parsebin` and hide that in such a
way that output pads are re-used (if compatible).

By analyzing the collection posted by parsebin, we can:
* Identify whether some output slots are no longer used (because the stream they
  currently handle is not present in the collection)
* Decide if some upcoming streams could re-use the existing slot

This supports both buffering and non-buffering modes.

Fixes #1651

5422c6c6d4 uridecodebin3: Atomically switch urisourcebin
When switching urisourcebin, ensure that we first unlink *all* pads from
decodebin3 before linking them again.

This is to ensure that decodebin3 completely knows that all previous pads are no
longer needed and can prepare itself to being re-used.

3ce62be851 subtitleoverlay: Also use "Decoder/Subtitle" elements
Elements that "decoded" subtitle formats to raw text were historically
classified as "Parser" and not "Decoder. This is being gradually fixed.

This commit ensures that both classification are allowed

c1d33126aa playbin3: Inform (uri)decodebin3 of the subtitle caps from playsink
Subtitles are better handled by overlayers/renderers within playsink. By
informing (uri)decodebin3 of the formats that can be handled we can avoid those
being "decoded" too early.

34a1245905 subparsers: Give proper category to subtitle "decoders"
Some subtitle "decoders" had a wrong category of "Parser", which `parsebin`
relies on to identify elements which do not *decode* streams but *parse* them.

This would cause such subtitle decoders to be plugged in within parsebin,
preventing the original stream to be properly used by (more efficient)
downstream decoders or subtitle renderers.

60d9cfc954 videorate: Correct segment-based calculations
It was adding and subtracting the segment base here and there, but it
was also doing so incorrectly, leading to various calculation errors.

Fixed a few bugs uncovered, related to getting a new segment:
* If we reset base_ts/next_ts/out_frame_count, also reset prevbuf
* Only do so if the new segment is different than the previous one

Also replaced a few occurrences of GST_BUFFER_TIMESTAMP with
GST_BUFFER_PTS for consistency.

Integrated the tests of
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2186
, now passing. The test_segment_update_same test had to be fixed,
because it was wrongly assuming that we would not fill the gap inside
the new-but-same segment.

e17c7a0b7f playbin3: Fix deadlock while selecting streams going to playing
In the following backtrace for the deadlock, we can see that:

- In T8 `uridecodebin3` is exposing a new pad, in `pad_added_cb`,
  `playbin3` is trying to get `GST_PLAY_BIN3_LOCK` in the callback. This
  threads holds its `SELECTION_LOCK` in F17 `reconfigure_output_stream`,
  which is looks right `decodebin3` is handling its selection state
  in that code path

- In T7 `playbin3` holds the `GST_PLAY_BIN3_LOCK` when calling
  `gst_element_post_message` in `gst_play_bin3_send_event` which is
  not necessary in that section of the code.

87bb3a8e2e subtitleoverlay: Handle video sink pad CAPS query earlier
The internal elements are only created when caps on both video and subtitle pads
are known.

Prior to that, a GST_QUERY_CAPS on a video sink pad would just return ANY
instead of giving a hint of what downstream can actually handle and
prefers. This could result in upstream elements (such as decoders) deciding on
chosing (in the best cases) a non-optimal caps or (in the worst case) caps that
couldn't be handled by the elements downstream of subtitleoverlay.

In order to fix that, we assume that all subtitle "elements" handle the subtitle
overlay composition feature/meta and handle `GST_QUERY_CAPS` ourselves if the
internal elements aren't present yet.

Fixes #3176

2d57bec920 decodebin3: Don't send sticky events to unlinked decoder
This causes a lot of nasty side effects (like decoders assuming they are
actually linked downstream).

The reason why this was done was to check whether a decoder could handle the
actual caps, but this is the wrong way to do it.

The proper way to query whether a decoder can handle certain caps is via
`GST_QUERY_ACCEPT_CAPS` which is already done just before.

94d74c8900 debug: add new element fakevideodec
The fake video decoder ignores input bitstream except
to enforce caps restrictions. It reads video width,
height and framerate from caps. Then it just pushes
video frames without doing any decoding.

The fake video decoder just draws a snake moving from
left to right in the middle of the frame. This is a
light weight drawing while it still provides an idea
about how smooth is the rendering.

The fake video decoder inherits from GstVideoDecoder.
It is useful to measure how smooth will be the whole
rendering pipeline if you had the most efficient video
decoder. Also useful to bisect issues for example when
suspecting issues in a specific video decoder.

Handles mpeg2, mpeg4, h263, h264, theora, vp8, wmv3, msmpeg,
flash-video, vp6, vp9, wmv1, wmv2, divx but more can be
added if needed.

For now it can only output RGBA, RGBx, BGRA, BGRx.

Its rank is 0 (none) but I added a property to change it so
that it can be selected by decodebin.

Back in the mists of time[1], we switched `giostream*` elements to not close the
stream on stop() so that applications that needed a handle to the stream after

Unfortunately, we also have cases[2] where waiting for the element to be
finalized is too late for the stream to be closed.

In order to not change the behaviour of the element, we add a property to allow
users to select the desired behaviour.

8b1500d7ff volume: support arbitrarily-large positive gains
The current limit is `x10`, which allows just `+20 dB` of gain.

While it may seem sufficient, this came up as a problem
in a real-world, non-specially-engineered situation,
in strawberry's EBU R 128 loudness normalization.
(https://github.com/strawberrymusicplayer/strawberry/pull/1216)

There is an audio track (that was not intentionally engineered that way),
that has integrated loudness of `-38 LUFS`,
and if we want to normalize it's loudness to e.g. `-16 LUFS`,
which is a very reasonable thing to do,
we need to apply gain of `+22 dB`,
which is larger than `+20 dB`, and we fail...

I think it should allow at least `+96 dB` of gain,
and therefore should be at `10^(96/20) ~= 63096`.

But, i don't see why we need to put any specific restriction
on that parameter in the first place, other than the fact
that the fixed-point multiplication scheme does not support volume
larger than 15x-ish.

So let's just implement a floating-point fall-back path
that does not involve fixed-point multiplication
and lift the restriction altogether?

4404e7203c decodebin3: Fix slot input linking when the associated stream has changed
Setting the input field on the empty slot prevents future linking of it and will
result in flow errors later on.

This was observed in WebKit's MediaStream source element, when it changes the
caps on one of its associated streams, from an encoded format to a raw video
format. The associated stream-id on the sticky stream-start event doesn´t
change, but the element creates a new GstStream with a different ID and sets it
on the stream-start event. Stream parsing is disabled in urisourcebin, so
decodebin3 handles the parsing. Without this patch we would end-up with unlinked
pads in decodebin3 after switching to the raw video format.

4dc503e1e4 decodebin3: Remove spurious input locking during parsebin reconfiguration
Commit 22917b140f added extra locks in
`reset_input_parsebin()` but all call sites of that function already take the
input lock.
