131679b9d0 mpegtsbase: Fix Program equality check
There was an issue with this equality check, which was to figure out what to do
with PCR pids (whether they were part of the streams present or not) and whether
we ignore PCR or not.

Turns out ... we already took care of that further up in the function.

The length check can be simplified by just checking whether the length of
the *original* PMT and the new PMT are identical. Since we don't store "magic"
PCR streams in those, we can just use them as-is.

6d228c420c tsdemux: Disable smart program update
The goal of this code was, for programs which were updates (i.e. adding/removing
streams but not completely changing) to allow dynamic addition/removal of
streams without completely removing everything.

But this wasn't 100% tested and there are a bunch of issues which make it fail
in plenty of ways.

For now disable that feature and force the legacy "add all pads again and then
remove old ones" behaviour to make it switch.

when when pad timestamps proceed past that point and mark
them as EOS. Otherwise, tsdemux continues streaming

f18186b5dc mpegts: Always clear packetizer on DISCONT push mode
If a discontinuity is detected in push mode, we need to clear the cached section
observations since they might have potentially changed.

This was only done properly when operating with TIME segments (dvb, udp,
adaptive demuxers, ...) but not with BYTE segments (such as with custom app/fd
sources).

We still don't want to flush out the PCR observations, since this might be
needed for seeking in push-based BYTE sources.

c81facec5f mpegts: Check continuity counter on section streams
This wasn't really done, and is needed in order to detect potential section
changes for sections that have got identical information (such as when switching
between streams that have the same PAT/PMT pid and subtable information).

Other checks exist in tsbase to detect if the "new" PAT/PMT really is an update or not.

a40842545f Revert "mpegtspacketizer: memcmp potentially seen_before data"
This reverts commit fcad4cc646.

This was wrong is so many ways.

* The memcmp was badly used (it should use == 0 to check the data is identical,
  and not != 0)
* There was no boundary checks on the present stream section_data when passing
  it to memcmp.
* The return value should have been TRUE (i.e. we have done all checks, none of
  them failed, therefore the section has been seen before)
* stream->section_data would *always* be NULL if the section had already been
  processed

8a2edc6581 tsdemux: Don't trigger a program change when falling back to ignore-pcr behaviour
Since commit a79a756b79 we could change to ignore-pcr automatically at 500ms
into a live stream when no PCR is seen by then. However the stream counting in
program change detection was wrongly considering ignore-pcr programs to have a
separate PCR PID, even though we are actually ignoring the PCR PID completely,
resulting in an erroneous program switch getting triggered from the different
stream count. This in turn would send an EOS and switch out the pads for what
actually is still the same program, while we intended to simply apply a
workaround for broken encoders.

10f72da504 mpegts: Handle "empty" PMT gracefully
Some streams have 2 PMT sections in a single TS packet. The first one is "valid"
but doesn't contain/define any streams. That causes an unrecoverable issue when
we try to activate the 2nd (valid) PMT.

Instead of doing that, pre-emptively refuse to process PMT without any streams
present within. We still do post that section on the bus to inform applications.

b99ecc78ca Replace gst-i18n-*.h with gi18n-lib.h
GLib guarantees libintl is always present, using proxy-libintl as
last resort. There is no need to mock gettex API any more.

This fix static build on Windows because G_INTL_STATIC_COMPILATION must
be defined before including libintl.h, and glib does it for us as part
as including glib.h.

d678d7136c tsdemux: Fix AC-4 detection
This regression was introduced by
https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/1102
and has been present since 1.18

* Stream Type 0x06 is defined in the base mpeg-ts specification as Private PES
Packets. Determining the content should be solely based on descriptors found
within the PMT.
* This was abused in that commit by defining a "bluray-only" stream type for AC4
: `ST_BD_AUDIO_AC4`
* This should be entirely handled in the regular private pes handling further
down in the code

273e2a1db6 mpegtsbase: Search SCTE-35 DRF_ID_CUEI in multiple registration descriptors
There are streams in the wild that have to add a SCTE-35 trigger in
another e.g. GA94 stream. Most encoders would replace the GA94
descriptor ID with the CUEI one temporarily, but there are some that
will add two registration ID descriptors, one with GA94 and one with
CUEI.

Failing to parse the CUEI registration ID in that case would return
FALSE in _stream_is_private_section , therefore setting it as known PES
and pushing packets downstream instead of calling handle_psi.

0ff569d408 tsdemux: Handle "negative" timestamps
This is only enabled in push time mode. Furthermore it's only enabled for now if
PCR is to be ignored.

The problem is dealing with streams where the initial PTS/DTS observation might
be greater than following ones (from other PID for example). Before this patch,
this would result in sending buffers without any timestamp which would cause a
wide variety of issues.

Instead, pad segment and buffer timestamps with an extra
value (packetizer->extra_shift, default to 2s), to ensure that we can get valid
timestamps on outgoing buffers (even if that means they are before the segment
start).
