Sebastian Dröge e58dceec3a qtmux: Reserve 256 bytes for CDP packets in pre-fill mode

Vivia Nikolaidou f2c2560db2 deinterlace: Closed caption pass-through
Pass through closed caption data when deinterlacing. When two
deinterlaced frames are created for the same interlaced frame (e.g.
fields=all), the second of the two frames will have no closed caption
data.

Also fixed memory leaks related to timecode meta pass-through.

Jan Schmidt f067b50dd6 rtspsrc: Add a small configurable teardown delay
This causes rtspsrc to send a teardown and wait on
PAUSED->READY transition, with a configurable delay.
Otherwise, typically teardown never gets sent in
playbin / uridecodebin where the transition back to NULL
happens too quickly.

The timeout is set to 100ms default.

Jan Schmidt f672116c72 splitmux: Improve handling of repeated timestamps
When handling input with timestamps that repeat, sometimes
splitmuxsink would get confused and ignore a keyframe.

The logic in question is a holdover from before the cmd queue
moved the file cutting to the multiqueue output side and made
it deterministic, so it's no longer needed on the input
here.

Always wait with starting the RTCP thread until either a RTP or RTCP

RTCP thread is started when requesting an early RTCP packet.

We want to wait with starting the RTCP thread until it's needed in order
to not send RTCP packets for an inactive source.

Alicia Boya García 025a430d08 qtdemux: rework segment event pushing, again
This patch aims at fixing the recent regressions in the adaptive test
suite.

All segment pushing in push mode is now done with
gst_qtdemux_check_send_pending_segment(), which is idempotent and
handles both edit lists cases and cases where the upstream TIME segments
have to be sent directly.

Fragmented files that start with a non-zero tfdt are also taken into
account, but their handling has been vastly simplified: now they are
handled as implicit default seeks so there is no need to extend the
GstSegment formulas as was being done before.

qtdemux->segment.duration is no longer modified when
upstream_format_is_time, respecting in this way the durations provided
by dashdemux and fixing bugs in reverse playback tests where mangled
durations appeared in the emitted segments.

Alicia Boya García 2c394304b7 qtdemux: Don't send EOS during upstream reverse playback
Upstream driving elements such as dashdemux often do reverse playback by
feeding qtdemux with the fragments containing the requested playback
range in reverse order.

But the requested playback range stop may be somewhere in the
middle of a fragment. In that case, a naive pts >= segment.stop
condition may declare end of segment prematurely when demuxing this
first fragment.

This used not to happen because there were places in moov parsing where
segment.stop was overwritten to GST_CLOCK_TIME_NONE even if
upstream_format_is_time -- resulting in this case in a segment with rate
< 0 and stop == -1 and hence not triggering the EOS check, but that was
likely an accident.

This patch modifies the EOS check to take this case into account, not
sending EOS when upstream_format_is_time if rate < 0.

This fixes adaptive.dash.playback.seek_end_live.DASHIF_livestream_testpic_2s

Thiago Santos bfd0e0225e qtdemux: rework segment event pushing
Instead of always keeping a safe segment (start=0) event from the beginning,
delay the creation of this event to when we really know the timestamp of the
first sample. This is important to properly start fragmented streams that
we might join in the middle or to play isolated fragment files that might
have an advanced tfdt.

Alicia Boya García c2a0da8096 qtdemux: Allow edit lists on fragmented files on push mode
Fragmented files often use elst.duration=0 which before
ee78825eae was wrongly interpreted as
having no frames.

Since that issue has now been fixed, there is no reason to disable edit
lists in fragmented files. This commit enables them, therefore producing
correct stream time for files containing edit lists.

Alicia Boya García 5388d6e6a2 qtdemux: fix computation of first_duration for fragmented files in push mode
Since ca068865c3 the duration of the first
frame is not used for estimating the frame rate.

For this purpose, stream->first_duration was initialized with the
duration of the first frame. In fragmented files, this was previously
done by peeking the first moof, but that can only be done in pull mode.

Fortunately, we don't really need to do that, at least with the current
design: When we are estimating the frame rate we already have the
sample table, regardless of the scheduling mode and whether the file is
fragmented or not, so we can obtain first_duration there much more
reliably.

This fixes frame rate estimation for fragmented files in push mode.

Vivia Nikolaidou d11339d616 splitmuxsink: Added new async-finalize mode
This mode is useful for muxers that can take a long time to finalize a
file. Instead of blocking the whole upstream pipeline while the muxer is
doing its stuff, we can unlink it and spawn a new muxer+sink combination
to continue running normally.

This requires us to receive the muxer and sink (if needed) as factories,
optionally accompanied by their respective properties structures. Also
added the muxer-added and sink-added signals, in case custom code has to
be called for them.

Xabier Rodriguez Calvar ee4b45da24 qtdemux: add context for a preferred protection
qtdemux selected the first system corresponding to a working GStreamer
decryptor. With this change, before selecting that decryptor, qtdemux
will check if it has context (a preferred decryptor id) and if not, it
will request it.

The request includes track-id, available key system ids for the
available decryptors and even the events so that the init data is
accessible.

[eocanha@igalia.com: select the preferred protection system even if not available]

Test "4. ClearKeyVideo" in YouTube leanback EME conformance tests 2016 for
H.264[1] uses a media file[2] with cenc encryption which embeds 'pssh' boxes
with the init data for the Playready and Widevine encryption systems, but not
for the ClearKey encryption system (as defined by the EMEv0.1b spec[3] and with
the encryption system id defined in [4]).

Instead, the ClearKey encryption system is manually selected by the web page
code (even if not originally detected by qtdemux) and the proper decryption key
is dispatched to the decryptor, which can then decrypt the video successfully.

Enrique Ocaña González 844423ff99 qtdemux: also push buffers without encryption info instead of dropping them
Test "17. PlayReadyH264Video" in YouTube leanback EME conformance tests 2016
for H.264[1] uses a media file[2] with cenc encryption whose first two 'moof'
boxes have no encryption information (no 'saiz' and 'saio' boxes).

Those boxes are actually not encrypted and the current qtdemux implementation
was just dropping them, breaking the test use case.

This patch detects those kind of situations and just lets the unencrypted
buffers pass. Of course, this needs some collaboration by the decryptors,
which should also do the same and not to try to decrypt those clear buffers.
