c51922b06c h265parse: Differentiate PREFIX SEI from SUFFIX
There is some code to fixup broken stream that uses the SEI location,
this code is meant to locate SUFFIX SEI only. This should prevent
unwanted side effect if SUFFIX SEI is used.

e88d848070 h265parse: Don't wait for next NAL if input is aligned
Waiting for the next NAL increases the latency. If alignment=nal/au
has been negotiated, assumes the the buffer contains a complete
NAL and don't expect a second start-code. This way, nal -> nal,
au -> au and au -> nal no longer introduce latency.

As a side effect, the collect_pad() function was not able to poke at the
following NAL. This call is now moved before processing the NAL, so
it's looking at the current NAL before it's ingested into the parser
state in order to dermin if the end of an AU has been reached. The AUD
injection state as been adapted to support this.

This change will break pipelines if alignment=nal is used without respecting the
alignment. Effectively, the parser will no longer fix the broken aligment
which will result in parser error and the termination of the pipeline. Such
issue existed in tsdemux element and might exist in any forks of that code.

4a91a98ea1 mpegtsdemux: Don't pretend doing NAL alignment
Per specification in 2.14.2 "For PES packetization, no specific data
alignment constraints apply". So we should not advertise NAL
alignment.

This bug was introduced at the same moment the alignment field was introduced
10 years ago. The plan was that alignment=none (or no alignment field) was to
be used for mpegtsdemux, but no one noticed the error. The reason is that at
the same moment, everything dealing with H264 started defaulting to AU
alignment.

https://bugzilla.gnome.org/show_bug.cgi?id=606662#c22

This patch will have a side effect that a parser is now needed after the
tsdemux element. The following pipeline will not negotiate anymore as the
mpegtsmux element requires alignment={nal,au}.

  ... ! tsdemux ! mpegtsmux ! ...

As a side effect, anyone that forked from tsdemux should updated their code to
fix this bug.

rtmp2: Avoid a deadlock when getting stats
We need to do this without holding the lock as the `g_async_queue_pop`
waits on the loop thread to deliver the stats. The loop thread might
attempt to take the lock as well, leading to a deadlock.

Taking a reference to the connection should be enough to keep this
safe.

468408c6a6 mpegtspacketizer: be more tolerant when parsing the adaptation field
According to the specification, the adaptation field length must be 183 if
there is no payload data and < 183 if the packet contains an adaptation
field and payload data.

Unfortunately some payloaders always set the flag for payload data, even if
the adaptation field length is 183.

Don't return with an error in this case. Clear the payload data flag
instead and parse the adaptation field as usual. This avoids visual
artefacts for such streams.

are placed in bitstream. When sps/pps are signalled only via caps
by upstream, however, the updated codec_data is mandatory for decoder
and therefore we shouldn't ignore them.

2f946274d5 mpegtsparse: Set delta unit flag on non-random-access buffers
If they don't have the random access flag set, they cannot be decoded
independently.

34af8ed66a mpegtsparse: Packetize output on default srcpad
Align buffer boundaries with mpeg-ts packets, instead of keeping
whatever packetization we have from the source (network, file reading).

e44cbfb1da mpegtsparse: Factor common code into mpegts_packet_to_buffer
The same code was used twice for turning an MpegTSPacketizerPacket into
a GstBuffer.

287f9b18b0 mpegdemux: Update the last_ts correctly if we have no DTS
If we have no DTS but a PTS then this means both are the same, and we
should update the last_ts with the PTS. Only if both are unknown then we
don't know the current position and should not update it at all.

Previously we would always update the last_ts to GST_CLOCK_TIME_NONE if
the DTS is unknown, which caused the position to jump around and to
cause spurious gap events to be sent.

5f95a9ec61 mpegpsdemux: Send gap events for late streams whenever updating the SCR
Instead of doing it on each packet and doing it based on the distance to
the previous SCR instead of based on the DTS.

Previously we would send gap events for audio all the time if the SCR
distance was 400ms because the threshold for audio is 300ms and by only
ever updating the position when the SCR updates we would always be 100ms
above the threshold and send needless gap events.

This fixes audio glitches on various files caused by gap events.

e2bdc0c48d yadif: Re-renable MMX asm on x86_64 with meson
The meson build doesn't automatically set HAVE_CPU_* defines
like autotools did, so the yadif plugin was being built without
the MMX assembler support

f72aaed9c7 timecodestamper: Add property to set the extra latency to introduce for waiting for LTC timecodes
Default to 150ms instead of 8 frames, which seems to work in the
majority of cases.

bebf20c906 h264parse: do not push wrong PTS with some raw files
Some raw h264 encoded files trigger the assignment of wrong PTS to buffers
when some SEI data is provided. This change prevents it to happen.

Also ensure this behavior is being tested.

We might have some old timecodes that are in the future now and have to
drop those to make sure that our queue is correctly ordered and we don't
have multiple timecodes for the same running time.
