963dda3482 tsdemux: Make latency configurable
Allows for "low latency" mpeg-ts mode which is not standard, but somewhat common.
For this to work the sender has to put timestamps at a higher frequency than the spec requires.

doesn't have any structure associated.

eaf918df03 tsdemux: Limit the maximum PES payload size
PES packets with size 0 are unbounded, and
could therefore overflow the 32-bit size
accumulator.

Add a 32MB limit, which is larger than
any PES packet should ever get. If one does,
then output a 32MB chunk and continue.

062ca5e55b h264parse: don't critical on VUI parameters > 2^31
A guint32 greater than 2^31 would be interpreted as negative by
gst_util_uint64_scale_int() and critical. Use the 64-bit integer version
of the function instead.

a427b36f79 tsdemux: do not error if buffer size is invalid due to DISCONT
Don't signal a pipeline error when processing incomplete
j2pk PES packets that are too small. That can happen normally
during a DISCONT and shouldn't shut down the whole pipeline

bc4c221be3 tsdemux: always take the seek segment stop into account

b4a298c80e tsdemux: Use gst_segment_do_seek()
Remove some custom and incomplete seek calculation
logic in favour of gst_segment_do_seek(), and
short-circuit any actual seeking or recalculation
if the position didn't change and just send an updated
segment directly.

This removes the custom seeking logic in favour of
using standard core seek handling.

aea20f207d rtponviftimestamp: add opt-out "drop-out-of-segment" property
The default behaviour of rtponviftimestamp is to drop buffers
outside the segment. This creates obvious problems for reverse
playback.

The ONVIF specification unfortunately doesn't describe how to handle
that specific use case, but we can expose a property to let the
user disable the dropping behaviour, and forward these buffers with
a G_MAXUINT64 ONVIF timestamp.

Also modify rtponvifparse to handle such timestamps appropriately.

5002efbf8d timecodestamper: Require a non-0/1 framerate on the pad templates
We reject caps with other framerates as it's impossible to generate
timecodes unless we actually know a constant framerate. Reflect this
also in the pad template caps.

aafda1c76f timecodestamper: Validate LTC timestamps before trying to use them
There's no point in working with invalid LTC timestamps as all future
calculations will be wrong based on this, and invalid LTC timestamps can
sometimes be read via the audio input.

96004cd751 siren: fix a global buffer overflow spotted by asan
This patch just enforces boudaries for the access to the
standard_deviation array (64 floats). Such case can be
seen with a corrupted stream, where there's no hope to
obtain a valid decoded frame anyway.

f65c8fff50 rtponviftimestamp: fix setting of the discontinuity flag
The D bit is meant to be set whenever there is a discontinuity
in transmission, and directly maps to the DISCONT flag.

The E bit is not meant to be set on every buffer preceding a
discontinuity, but only on the last buffer of a contiguous section
of recording. This has to be signaled through the unfortunately-named
"discont" field of the custom NtpOffset event.

678064d603 timecodestamper: Rewrite element API and code flow
We now have a single property to select the timecode source that should
be applied, and for each timecode source the timecode is updated at
every frame. Then based on a set mode, the timecode is added to the
frame if none exists already or all existing timecodes are removed and
the timecode is added.

In addition the real-time clock is considered a proper timecode source
now instead of only allowing to initialize once in the beginning with
it, and also instead of just taking the current time we now take the
current time at the clock time of the video frame.
