The issue is that we rely on `decodebin::autoplug-select` to `SKIP`
unwanted pads, that signal was first provided to select factories during
autoplugin, not totally thought to avoid exposing pads. For streams
muxed directly in raw, decodebin has nothing to plug after the demuxer
and the pad is exposed right away, meaning that we do not have any
chance to avoid that pad to be exposed. This patch takes that limitation
into account and checks the stream ID of the pads exposed by decodebin
before exposing them itself, so we end up using the right pad even if
more are uselessly exposed by decodebin.

When tunneling RTP over RTSP the stream transports are stored in a hash
table in the GstRTSPClientPrivate struct. They are used for, among other
things, mapping channel id to stream transports when receiving data from
the client. The stream tranports are created and added to the hash table
in handle_setup_request(), but unfortuately they are not removed in
handle_teardown_request(). This means that if the client sends data on
the RTSP connection after it has sent the TEARDOWN, which is often the
case when audio backchannel is enabled, handle_data() will still be able
to map the channel to a session transport and pass the data along to it.
Which eventually leads to a failing assert in gst_rtsp_stream_recv_rtp()
because the stream is no longer joined to a bin.
We avoid this by removing the stream transports from the hash table when
we handle the TEARDOWN request.

Texture upload mechanism used by gstreamer-vaapi relies on 8 bpc.
In latest mesa versions the first fbconfig might not be 8 bit, so iterate
over it to find the correct config with supported values.
This also adds 8 bit alpha size to the framebuffer configuration which is
required to get it working properly.

Preserve the previous behaviour where:
name, val="5";
passed to gst_structure_from_string would have resulted in an int value,
rather than a string, despite the quote marks.
This will be changed to being interpreted as a string in the future, but
for the time being we will issue a warning about this to give users time
to fix their code to no longer rely on this bug.

This AV1 parse implements the conversion between alignment of obu,
tu and frame, and the conversion between stream-format of obu-stream
and annexb.
TODO:
1. May need a property of operating_point to filter the OBUs
2. May add a property to disable deep parse.

Allow a string in gst_string_unwrap to include unescaped characters that
are not in GST_STRING_IS_ASCII. This extra leniency allows
gst_structure_from_string to, e.g., receive
name, val=(string)"string with space";
Note that many gst tests, and potentially users, exploited this behaviour
by giving
name, val="string with space";
i.e. without the (string) type specifier. This was allowed before
because, without a type specifier, the string was passed to
_priv_gst_value_parse_string with unescape set to TRUE, *rather* than
being sent to gst_string_unwrap. This caused a difference in behaviour
between strings that are or are not preceded by (string). E.g.
name, val=(string)"string with space";
would fail, whilst
name, val="string with space";
would not. And
name, val=(string)"\316\261";
would produce a val="α", whereas
name, val=(string)"\316\261";
would produce a val="316261" (a bug).
The current behaviour is to treat both of these cases the same, which is
desirable. But in order to not break potentially common usage of this
discrepancy (it was in our own tests), the best option is to make string
parsing less strict in general.
New behaviour would be for
name, val=(string)"string with space";
to pass and give val="string with space", and
name, val="\316\261";
would produce a val="α".
Also changed deserializing string test to expect successes where
previously a failure was expected.
In a similar way, this also effected the deserializing of GstStructure,
GstCaps, GstTagList and GstCapsFeatures. So, now
name, val=(structure)"sub-name, sub-val=(string)\"a: \\316\\261\";";
will also pass and give sub-val="a: α". Note that the quote marks
and backslash still need to be escaped for the sub-structure, but other
characters need not be.

No longer call _priv_gst_value_parse_string with unescape set to TRUE
before passing a value to gst_value_deserialize in
_priv_gst_value_parse_value. This latter function is called by
gst_structure_from_string and gst_caps_from_string.
When gst_structure_to_string and gst_caps_to_string are called, no
escaping is performed after calling gst_value_serialize. Therefore, by
unescaping the value string, we were introducing an additional operation
that was not performed by the original *_to_string functions. In
particular, this has meant that the derialization functions for many
non-basic types are incomplete reverses of the corresponding
serialization function (i.e., if you pipe the output of the
serialization function into the deserialization function it could fail)
because they have to compensate for this additional escaping operation,
when really this should be the domain of the deserialization functions
instead.
Correspondingly changed a few deserialization functions.

Some GPUs (especially NVIDIA) are complaining that GPU is still busy
even we did 50 times of retry with 1ms sleep per failure.
Because DXVA/D3D11 doesn't provide API for "GPU-IS-READY-TO-DECODE"
like signal, there seems to be still no better solution other than sleep.

The vabasedec's display and decoder are created/destroyed between
the gst_va_base_dec_open/close pair. All the data and event handling
functions are between this pair and so the accessing to these pointers
are safe. But the query function can be called anytime. So we need to:
1. Make these pointers operation in open/close and query atomic.
2. Hold an extra ref during query function to avoid it destroyed.

Due to the may_cancel flag in GstRTSPConnection, receiving might not get
cancelled when supposed to. In this case, gst_rtsp_src_receive_response
will have to wait until timeout instead but if busy receiving RTP
data, this timeout will never occur.
With this patch, gst_rtsp_src_receive_response returns GST_RTSP_EINTR
if flushing is set to TRUE instead of continuing to receive.

This reduces the chance of the main thread getting starved while trying
to shut down the test, potentially causing a timeout.
Even on an idle 96-processor system this reduces the duration of the
systemclock tests from ~8s to ~3s.

These parameters are incorrectly regarded as mutable in G-IR making them
"incompatible" with languages that are explicit about mutability like
Rust. In order to clean up the code and expected API there, update the
signatures here, right at the source (instead of overriding them in
Gir.toml and hoping for the best).

This will only make use of the framerate if the subclass is chaining up
BaseSink::set_caps(). Otherwise it will have the same behaviour as the
basesink default.
Doing so is useful if video buffers don't contain a duration to
calculate a default duration, and various video sinks already implement
a custom version of this.
