8d1122013b audiodecoder: add _finish_subframe() method
This allows us to output audio samples without discarding
any input frames, which is useful for some formats/codecs
(e.g. the MonkeysAudio decoder implementation in ffmpeg
which will might return e.g. 16 output buffers for an
input buffer for certain files).

In the past decoder implementations just concatenated
the returned audio buffers until a full frame had been
decoded, but that's no longer possible to do efficiently
when the decoder returns audio samples in non-interleaved
layout.

Allowing subframes to be output before the entire input
frame is decoded can also be useful to decrease startup
latency/delay.

675415bf2e gl: try to use highp precision where supported
The use of mediump as a specifier in GLSL shaders will have limited
resolution and when used as texture coordinates may become inaccurate
over texture sizes of 1024.

f90dac8d48 rtsp-connection: Make use of new GstRTSPMessage API for directly storing a body buffer and add API for writing multiple messages
By doing so we can send a whole GstBufferList and each memory in the
contained buffers without copying into a single memory area and with a
single writev() call. This improves performance considerably for
high-packet-rate streams.

This depends on https://gitlab.gnome.org/GNOME/glib/merge_requests/333
to be efficient, otherwise each chunk of memory is a separate write()
call.

b3c0d8b89b rtsp-message: Add support for storing GstBuffers directly as body payload of messages
This makes it unnecessary for callers to first merge together all
memories, and it allows API like GstRTSPConnection to write them out
without first copying all memories together or using writev()-style API
to write multiple memories out in one go.

c02d3b03c2 videotimecode: Add API for initializing from a GDateTime with validation
The old API would only assert or return an invalid timecode, the new API
returns a boolean or NULL. We can't change the existing API
unfortunately but can at least deprecate it.

1edb2c4242 audio-converter: add API to determine passthrough mode
audioconvert's passthrough status can no longer be determined
strictly from input / output caps equality, as a mix-matrix can
now be specified.

We now call gst_base_transform_set_passthrough dynamically, based
on the return from the new gst_audio_converter_is_passthrough()
API, which takes the mix matrix into account.

5303e2c32b rtcpbuffer: add support XR packet parsing
According to RFC3611, the extended report blocks in XR packet can
have variable length. To visit each block, the iterator should look
into block header. Once XR type is extracted, users can parse the
detailed information by given functions.

Loss/Duplicate RLE
The Loss RLE and the Duplicate RLE have same format so
they can share parsers. For unit test, randomly generated
pseudo packet is used.

Packet Receipt Times
The packet receipt times report block has a list of receipt
times which are in [begin_seq, end_seq).

Receiver Reference Time paser for XR packet
The receiver reference time has ntptime which is 64 bit type.

DLRR
The DLRR report block consists of sub-blocks which has ssrc, last RR,
and delay since last RR. The number of sub-blocks should be calculated
from block length.

Statistics Summary
The Statistics Summary report block provides fixed length
information.

VoIP Metrics
VoIP Metrics consists of several metrics even though they are in
a report block. Data retrieving functions are added per metrics.

e0268c02ab audiodecoder: add API for setting caps on the source pad
This patch adds API in the audio decoder base class for setting the arbitrary
caps on the source pad.  Previously only caps converted from audio info were
possible.  This is particularly useful when subclass wants to set caps features
for audio decoder producing metadata.

f766b85b96 rtpbasepayload: rtpbasedepayload: Add source-info property
Add a source-info property that will read/write meta to the buffers
about RTP source information. The GstRTPSourceMeta can be used to
transport information about the origin of a buffer, e.g. the sources
that is included in a mixed audio buffer.

A new function gst_rtp_base_payload_allocate_output_buffer() is added
for payloaders to use to allocate the output RTP buffer with the correct
number of CSRCs according to the meta and fill it.

RTPSourceMeta does not make sense on RTP buffers since the information
is in the RTP header. So the payloader will strip the meta from the
output buffer.

GstSdp.sdp_message_parse_buffer(bytes(text.encode()), msg)

56ab7e0e1d dmabufallocator: adds gst_dmabuf_allocator_alloc_with_flags
If we can guarantee the lifetime of the fd is longer than
the memory, we can use DONT_CLOSE flag not to close when release.
But it's not provided in gstdmabuf yet while gstfdmemory does.

For example, in case of using VA-API or MSDK, we would need this api.
Otherwise we should call dup to duplicate the fd.

9dceb6ca52 video: Add support for VANC and Closed Caption
This commits add common elements for Ancillary Data and Closed
Caption support in GStreamer:

* A VBI (Video Blanking Interval) parser that supports detection
  and extraction of Ancillary data according to the SMPTE S291M
  specification. Currently supports the v210 and UYVY video
  formats.

* A new GstMeta for Closed Caption : GstVideoCaptionMeta. This
  supports the two types of CC : CEA-608 and CEA-708, along with
  the 4 different ways they can be transported (other systems
  are super-set of those).

10c161c7a7 docs/libs: The big spring cleanup
* Explicitely specify which headers aren't to be included in gtkdoc-scan
  This is essentially all the headers that are not installed and only
  for internal/local usage. This also includes the orc-generated headers.
* Remove all symbols/sections that are no longer present (due to accurately
  scanning only the headers we need).
* Add or expose sections which weren't previously exposed
* Make sure the "unified" library headers (ex: gst/video/video.h) are used
  everywhere applicable. Only use the specific headers where applicable
  (such as the GL-implementation-specific objects)
* Add all documentation which was not previously exposed in the right sections
* Update 'types' file to get as many runtime information as possible

This brings down the number of unused symbols to 15 (from over 300).
