Higher value might be too big (in particular with many VPNs `webrtcsink`
won't work with the default 1400 MTU).
1200 is the default value in libwebrtc and it is references in several
places there.
It is now guaranteed that each fragment is at most fragment-duration
long unless the one and only GOP of the fragment is longer than that.
The first (non-EOS) stream determines the duration of each fragment and
all other streams are drained to at most the fragment end timestamp
determined this way.
In addition the next fragment's target time is now at the end of the
previous fragment plus fragment-duration instead of using
first-fragment + N*fragment-duration
regardless of where fragments were split before.
That is, fmp4mux now uses the same strategy as used by splitmuxsink and
as is required e.g. by HLS with regards to the target duration.
This avoids full traversals of the sessions HashMap.
Also fixes accidental session teardown when a producer is stopped while
also in a session as a consumer.
Always first try draining queued data in the loop and only start waiting
if there's nothing to drain right now. Otherwise data might have to be
drained right now but we still wait and nothing is ever waking up the
source pad task again.
Also make sure to not wait multiple times on the same gst::ClockId but
instead unset it after waiting on it and no new one was scheduled in the
meantime. Future waits on the same ClockId will immediately return and
instead we should wait on the condvar if no new ClockId is available.

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

hlssink can be built by default because it has no dependencies.
tutorial and rsfile should not be built by default because they are
not very useful, and flavors should not be built by default because
it's very incomplete.
