818f64a641 splitmuxsrc: Calculate the end offset of a fragment once known 
If a new fragment is added with a valid duration but no offset then the start
offset is set later based on the end offset of the previous fragment. At that
point the end offset of this fragment can also be calculated and not doing so
would give the next fragment the same start offset.

f9845d0266 flacparse: Improve header validity checks 
Allow sample rate, number of channels and bps to change and in that case update
the caps accordingly.

Also move (non-fatal) validity checks and storing of the header values outside
the actual parsing once we actually know that a valid frame is available.

And also don't warn on the last frame with fixed block size blocking strategy
that the block size has changed: the last frame is allowed to be smaller.

19359e2b25 qtdemux: Make sure there are enough offsets to read when parsing samples 
While this specific case is also caught when initializing co_chunk, the error
is ignored in various places and calling into the function would lead to out of
bounds reads if the error message doesn't cause the pipeline to be shut down
fast enough.

To avoid this, no matter what, make sure enough offsets are available when
parsing them. While this is potentially slower, the same is already done in the
non-chunks_are_samples case.

85969fdaa7 level: Fix integer overflow when filling LevelMeta 
The level in GstAudioLevelMeta is represented as a signed 8bit value from 0 to
127 (with 127 meaning silence). When converting from double, make sure to clip
the value, this also prevent integer overflow in the conversion. This fixes an
issue where a lower then -127db is reported and random level with near silent
streams (due to integer overflow).

835e232e8c rtspsrc: Use a flow combiner at the source pads instead of custom logic 
Most importantly, this ensures that UDP streams still continue to run even if
they are not linked for a while. With decodebin3 the pads will all be unlinked
unless selected, and selecting a stream at a later time would otherwise switch
to a stream with a stopped udpsrc.

Apart from that this also ensures that actual errors from handling RTP packets
between udpsrc and the source pads are not silently ignored but considered
errors like they would be for TCP/interleaved.
