Add the minimum-update-interval property to the clock, with a default
of 50ms and don't send polling requests faster than that. That helps to
ensure we spread the initial observations out a little - startup takes
a little longer, but tracking is more stable.
Move the discont skew limiting code inside an if statement, so that
it's only done when the linear regression succeeds and the clock
parameters might actually change.
Add domain checks for the input values, and a variable precision
calculation that loops if necessary to ensure we never overflow
accumulators and then silently produce garbage results.
Make the (non-public) linear regression function available for
unit testing by putting it in a separate source file the test
can include. Add a unit test that the new regression function
produces sensible results for several inputs taken from real-world
captures.
Allow setting a GstBus on the network clock client
via a new 'bus' object property. If a bus is set, the
clock will output an element message containing statistics
about new clock observations and the clock correlation.
When the local clock is synchronised with the remote, limit the
maximum jump in the clock at any point to be one average RTT to
the server. Also, publish in the bus message whether we are
synched with the remote or not.
gst_clock_add_observation_unapplied() adds a new master/slave clock
observation and runs the regression without activating the new
calibration results.
gst_clock_adjust_with_calibration() uses directly passed calibration
parameters, instead of using the clock's current calibration,
allowing for calculations using pending or old calibration params
Otherwise the struct is going to be copied, which is not very efficient. And
also has the nice side effect that modifications of the struct might be
done in a copy, and we later use the original struct without the changes.
Caused LATENCY queries to always return the initialization values in one of my
tests, instead of the actual values reported by child elements.
... and only unblock when either a) the pad becomes active and the event
should be forwarded or b) the active pad went EOS itself.
Otherwise it can happen that we switch from a longer track that is not EOS yet
to a shorter track that already is EOS, but the shorter track won't have any
possibility to send its EOS event downstream anymore.

Both for the peer filter caps and the converted caps based on the peer caps.
If the peer filter caps are EMPTY, the peer caps query will also return
EMPTY. There's no ned to both downstream/upstream with this query.
API: GST_LEVEL_MAX
By compiling gstreamer (or plugins) with GST_LEVEL_MAX defined, only
the debugging statements at or below that level will be compiled in.
This allows compiling in some debugging (like errors and warnings) which
helps in debugging, but without the full cpu/memory overhead of all debugging
enabled.
Previously GStreamer got access to the libcheck interface by including
libs/gst/check/check.h which in turn included internal-check.h in the
same directory. internal-check.h was generated by copying
libs/gst/check/libcheck/check.h which in turn was generated from
check.h.in in the same directory. In this case generating
libs/gst/check/libcheck/check.h is unnecessary, in addition this file
was accidentally distributed in generated project tarballs.
Now libs/gst/check/internal-check.h is generated directly from
libs/gst/check/libcheck/check.h.in by configure. This means that the
libcheck source must include internal-check.h instead of the previously
generated libs/gst/check/libcheck/check.h. However the unnecessary
intermediate step is now skipped.

Pools are allowed to change the size in order to adapt padding. So
don't check the size. Normally pool will change the size without
failing set_config(), but it they endup changing the size before
the validate method may fail on a false positive.

Add a function to check if the preset iface implementation is editable and
document this from the implementers perspective.
