This introduce a library which contains a set of base classes which
handles the parsing and the state tracking for the purpose of decoding
different CODECs. Currently H264, H265 and VP9 are supported. These
bases classes are used to decode with low level decoding API like DXVA,
NVDEC, VDPAU, VAAPI and V4L2 State Less decoders. The new library is
named gstreamer-codecs-1.0 / libgstcodecs.
- Display caps of the pad we actually tried to link.
- Use the template caps as the filter is likely to not have any caps set
yet.
- Log pad name as well.
The approach is quite simple and doesn't take all use cases into account,
it only implements support when we are using the internal timecode we
create ourself.
Also the way we compute the sought frame count is naive, but it works
for simple cases.
As per discussion in the bug, remove the drop state from transportreceivebin.
Dropping data is necessary, but for bundled config, needs to happen
further downstream after mixed flows have been separated.
Also support switching back to BLOCK from PASS state.

Add a missing dependency to wl_client_dep for the wayland build. Some distros
have the wayland-client headers not installed in /usr/include (which is perfectly
valid, the pkg-config .pc file gives the right feedback).
This commit moves parsing code for superframe and frame header into
handle_frame() method, and removes parse() implementation from vp9decoder
baseclass.
The combination of
- multiple frames are packed in a given input buffer (i.e., superframe)
- reverse playback
seems to be complicated and also it doesn't work as intended in some case
The most common audio sample rate in AV streams is 48kHz, and the most
common device output sample rate is 48kHz. This allows handing of 48kHz
input streams without resampling.
Remove comments about avoiding the use of 48kHz.
This change is needed to support 2K DCI video modes.
Version 10.8 of the Decklink SDK supported DCI video modes for output
only. This updated version drops that restriction.
The current latest version of the Decklink SDK is 11.5, however
the gstreamer decklink plugin is not compatible with API changes
introduced in version 11 of the SDK. Therefore I have opted to upgrade
to the latest 10.x version instead.

* Remove redundant variables for width/height and par from GstD3D11Window.
GstVideoInfo holds all the values.
* Don't need to pass par to gst_d3d11_window_prepare().
It will be parsed from caps again
* Remove duplicated math
Fixing regression of the commit 9dada90108
Filter operates on raw data so don't allow decodebin to produce
encoded data if one is defined.
My use case here is keeping the video stream untouched but apply a filter
on the audio one, while keeping the same audio format.
gst_d3d11_result() will print warning message when HRESULT != S_OK.
However, since the retry is trivial stuff, check hr == E_PENDING first
and do not warn it.
Instead of synchronising at the ICE transport, do clock sync for the
RTP stream at the DTLS transport via the dtlssrtpenc rtp-sync
property. This avoids delaying RTCP while waiting until it is time
to output an RTP packet when rtcp-mux is enabled.

We do not have a way to know the format modifiers to use with string
functions provided by the system. `G_GUINT64_FORMAT` and other string
modifiers only work for glib string formatting functions. We cannot
use them for string functions provided by the stdlib. See:
https://developer.gnome.org/glib/stable/glib-Basic-Types.html#glib-Basic-Types.description
F.ex.

In the process, we're also following the DASH MPD spec more closely
now, which specifies that ranges must follow RFC 2616 section 14.35.1:

The DXGI_PRESENT_ALLOW_TEARING flag might cause unexpected tearing
side effect. Setting it in fullscreen mode only seems to be
the correct usage as in the Microsoft's direct3d examples.
In case the application has to deal with fussy servers. User agent
sniffing is so last decade.
Adds a property to set the Flash version on both the sink and the src.
The default stays the same (IIRC, Flash plugin for Linux from 2009).
DXVA spec is saying that the size of bitstream buffer provided by hardware decoder
should be 128 bytes aligned. And also the host software decoder should
align the size of written buffer to 128 bytes. That means if the slice
(or frame in case of VP9) size is not aligned with 128 bytes,
the rest of non 128 bytes aligned memory should be zero-padded.
In addition to aligning implementation, some variables are renamed
to be more intuitive by this commit.
The former uses a thread-safe way of getting statistics from the
connection without having to protect the fields with a lock.
The latter produces a zeroed statistics structure for use when no
connection exists.
