It attempts to produce a (nearly) gapless live stream by synchronizing
its output to the running time and forwarding the next input buffer if
its start is (nearly) flush with the end of the last output buffer.
If the input buffer is missing or too far in the future, it duplicates
the last output buffer with adjusted timestamps. If it is operating on a
raw audio stream, it will fill duplicate buffers with silence.
If an input buffer arrives too late, it is thrown away. If the last
input buffer was accepted too long ago (according to `late-threshold`),
a late input buffer is accepted anyway, but immediately considered a
duplicate. Due to the silence-filling, this has no effect on audio, but
video gets a "slideshow" effect instead of freezing completely.
The "many-repeats" property will be notified when this element has
recently duplicated a lot of buffers or recovered from such a state.

Fixed following warning.
gst-plugins-rs| WARNING: You should add the boolean check kwarg to the run_command call.
gst-plugins-rs| It currently defaults to false,

raised the dependency via bumping the dav1d rust crate used, but didn't add
a requirement at meson level, thus with automatic or enabled option for dav1d
it would pass with an older failure, but then during compilation phase fail
with:

Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/issues/1410
Created a new plugin 'webrtchttp' to implement all the
WebRTC HTTP protocols under /net/webrtc-http directory.
WhipSink wraps around 'webrtcbin' with HTTP capabilites
to exchange SDP offer/answer so an ICE/DTLS session can
be established between the encoder/media producer (WHIP client)
and the broadcasting ingestion endpoint (Media Server).
Once the ICE/DTLS session is set up, the media will
flow unidirectionally from the WHIP client to the
broadcasting ingestion endpoint (Media Server).

Writing a proper "depfile" to follow depending files, based on depfiles
generated by rustc.
This is based on work done while working on gobject-examples-rs
This allows for faster rebuild avoiding to run the target when nothing
changed.
This approach is not ideal as we should find a way to actually know when
to rebuild based on information from cargo itself but there seem to be
no way to do it at this point.
This plugin takes I420/YUV and appends an alpha plane to give YUVA/A420
to round the corners analogous to the border-radius in CSS. Other video
formats like NV12 not supported yet. Support for other planar formats
will follow.
Not all ways of specifying border-radius as in CSS are implemented at
the moment. Currently, we only support specifying it in pixels and it
gets applied uniformly to all corners.
csound-sys can detect the system lib using either pkg-config or using
the CSOUND_LIB_DIR env variable.
The former case just work but the second is trickier as we need to
ensure that CSOUND_LIB_DIR is defined when building.
So we no longer try to detect the lib using find_library() if user
didn't define the env variable as the build will fail later.
Also explicitly pass the env variable to cargo so user can now call
'CSOUND_LIB_DIR=/usr/lib64 meson build && ninja -C build'
and have it work without repassing the env variable to ninja.
Using ubuntu 20.04, the build was failing with version
cargo 0.47 / rustc 1.47.
Following this discussion:
https://github.com/rust-lang/cargo/issues/9340
it appears that rustc 1.52 is the minimum version.
