b6168c7255 fmp4mux: Fix draining in chunk mode if keyframes are too late 
We would create another chunk that ends after the fragment end, and
would from then on consider the stream always filled for the chunk
because it starts after the current fragment end (i.e. nothing would go
into this fragment).

This is obviously wrong because the actual fragment end moved further
ahead because of the additional chunk.

460d6e1a74 mp4, fmp4: fix byte order for opus extension 
The "Encapsulation of Opus in ISO Base Media File Format" [1] specifications,
§ 4.3.2 Opus Specific Box, indicates that data must be stored as big-endian.

In `write_dops`, `to_le_bytes` variants were used.

d2947ed1f3 Revert "fmp4: Return a running time in get_next_time()" 
This reverts commit 04bb7b4db0.

As Sebastian points out, the chunk PTS is already in running time, so
this was wrong from the start.

5bbbd7bd23 fmp4: Use updated start_pts when checking stream filled 
After calculating the earliest pts, the fragment_start_pts and
chunk_start_pts in State are updated. However, when checking if the
stream is filled, the previous start_pts (set to None) is used instead.
This means that chunk_filled and fragment_filled will be false the first
time aggregate() is called, assuming timeout is false, all_eos is false,
and the sinkpad is not EOS. This requires aggregate() having to be
called a second time before the first fragment is sent.

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:

58a6dbacca fmp4mux: Pass one more buffer in test_buffer_multi_stream_short_gops test 
This works around non-determinism in aggregator where depending on
timing it can happen that it consumes all buffers from both pads or
waits for another buffer on one pad while the other one already has one.

The effect in this test was that it sometimes timed out. By providing
one more buffer it is guaranteed now that at this point the muxer is
beyond the end of the first fragment.

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.

1eea2219c6 mp4mux: Adjust durations and possibly stream start time on encountering a gap buffer 
If there was a previous sample in this stream then its duration needs to
be extended by the gap position, and if there was none then the start
time of the whole stream has to be shifted by the duration.

Not doing so causes timestamps to be offset wrongly by the duration of
the gap.

a7c75f8066 fmp4mux: Crank clock for the first fragment in more tests 
Due to how aggregator works, it depends on how buffers are pulled
whether aggregate() is called again or it is waiting for a timeout or EOS:

works:
  - pad 1: 4 buffers, pad 2: 4 buffers
  - aggregate ready: take all 4/4 buffers
  - pad 1: 1 buffers, pad 2: 1 buffer
  - aggregate ready: take all 1/1 buffers

waits:
  - pad 1: 5 buffers, pad 2: 4 buffers
  - aggregate ready: take all 5/4 buffers
  - pad 1: 0 buffers, pad 2: 1 buffer
  - aggregate not ready: waiting for timeout or EOS

Also don't manually set the clock time as that's unnecessary.
