Arun Raghavan 6d248c70dd fmp4: Return a running time in get_next_time() 
We were currently returning a value based on the next chunk PTS, but the
expectation in GstAggregator is that we return a running time. This
resulted in spurious wakeups and warnings like:

Sebastian Dröge e52bb160c7 fmp4mux: Accept more data on already filled streams if the remaining streams need more data for finishing a GOP 
In other words, continue queueing buffers in sync from all streams until
all of them are ready for draining instead of stopping to queue buffers
on every stream that is already filled individually.

Sebastian Dröge da7743d2e7 fmp4mux: Handle GOPs ending after the desired fragment end correctly 
Either create further chunks if enough data is queued or simply start
the new fragment at a later time if the keyframe is later.

Sebastian Dröge a01437b675 fmp4mux: Add support for sub-fragments / chunking 
Allow outputting sub-fragments (chunks in CMAF terms) that are shorter
than the fragment duration and don't usually start on a keyframe. By
this the buffering requirements of the element is reduced to one chunk
duration, as is the latency.

This is used for formats like low-latency / LL-HLS and DASH.

Guillaume Desmottes b9e203d6c1 fmp4mux: add 'offset-to-zero' property 
Add it only to 'isofmp4mux', the onvif variant already does this and
CMAF and DASH are always single-stream so you rely on inter-container
synchronization via the running-time.

Sebastian Dröge fb745f077b fmp4mux: Skip gap buffers earlier to consider them for the sample durations and fragment start durations

Sebastian Dröge 93ba677b18 fmp4mux: Handle EOS correctly if it happens before a fragment start time was determined 
Whatever earliest time we have at that point is going to be the start
time.

Also handle the case correctly where all inputs are EOS before any
buffers were received at all.

Sebastian Dröge 6c15bba592 fmp4mux: Re-work buffer dequeueing and calculations of timestamps 
Especially simplify calculation of ONVIF UTC times. As a side-effect
this reduces the number of times the running times of a buffer are
calculated, and also causes streams to be interleaved correctly in ONVIF
mode if there is a non-constant UTC-to-running-time difference.

Sebastian Dröge 8e2a6500aa fmp4mux: Clip negative PTS to zero/last PTS instead of erroring out 
This can happen at the beginning of a stream if upstream is
rtpjitterbuffer and it has problems figuring out timestamps in the
beginning due to resetting / skew.
