21378d83c2 rtpssrcdemux: Forward serialized events to all pads
While forwarding serialized event, we use gst_pad_forward() function.
In the forward callback (GstPadForwardFunction) we always return
TRUE. Returning true there will stop the dispatching procedure. As a
side effect, only one events is receiving the events. This breaks
when sending EOS from the applicaiton, it also breaks the latency
tracer.

753b7c17f3 matroskademux: Defer seeks received before GST_MATROSKA_READ_STATE_DATA
This patch enables matroskademux to receive seeks before it reaches
GST_MATROSKA_READ_STATE_DATA.

Closes https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/issues/514

This also enables receiving seeks in the element READY state.

When such a seek is received, it is stored to be later handled when
GST_MATROSKA_READ_STATE_DATA is reached.

8fc8b7ee33 rtpsession: Implement reset
Reset RTPSession when rtpsession changes state from PAUSED to READY.
Without this change, a stored last_rtptime in RTPSource could interfere
with RTP timestamp generation in RTCP Sender Report.

5fcb7f715a qtmux: round to nearest when computing mehd and tkhd duration
This fixes a bug where in some files mehd.fragment_duration is one unit
less than the actual duration of the fragmented movie, as explained below:

mehd.fragment_duration is computed by scaling the end timestamp of
the last frame of the movie in (in nanoseconds) by the movie timescale.

In some situations, the end timestamp is innacurate due to lossy conversion to
fixed point required by GstBuffer upstream.

Take for instance a movie with 3 frames at exactly 3 fps.

$ gst-launch-1.0 -v videotestsrc num-buffers=3 \
  ! video/x-raw, framerate="(fraction)3/1" \
  ! x264enc \
  ! fakesink silent=false

dts: 999:59:59.333333334,  pts: 1000:00:00.000000000, duration: 0:00:00.333333333
dts: 999:59:59.666666667,  pts: 1000:00:00.666666666, duration: 0:00:00.333333334
dts: 1000:00:00.000000000, pts: 1000:00:00.333333333, duration: 0:00:00.333333333

The end timestamp is calculated by qtmux in this way:

end timestamp = last frame DTS + last frame DUR - first frame DTS =
  = 1000:00:00.000000000 + 0:00:00.333333333 - 999:59:59.333333334 =
  = 0:00:00.999999999

qtmux needs to round this timestamp to the declared movie timescale, which can
ameliorate this distortion, but it's important that round-neareast is used;
otherwise it would backfire badly.

Take for example a movie with a timescale of 30 units/s.

0.999999999 s * 30 units/s = 29.999999970 units

A round-floor (as it was done before this patch) would set fragment_duration to
29 units, amplifying the original distorsion from 1 nanosecond up to 33
milliseconds less than the correct value. The greatest distortion would occur
in the case where timescale = framerate, where an entire frame duration would
be subtracted.

Also, rounding is added to tkhd duration computation too, which
potentially has the same problem.

05bd25ea35 qtdemux: Don't switch active streams and old streams ...
... before the old streams is not exposed yet for MSS stream.

In case of DASH, newly configured streams will be exposed
whenever demux got moov without delay.
Meanwhile, since there is no moov box in MSS stream,
the caps will act like moov. Then, there is delay for exposing new pads
until demux got the first moof.

So, following scenario is possible only for MSS but not for DASH,
STREAM-START -> CAPS -> (configure stream but NOT EXPOSED YET)
-> STREAM-START-> CAPS (configure stream again).

In above scenario, we can reuse old stream without any stream reconfigure.

af0e30d545 splitmuxsink: Do not hardcode frames_of_daily_jam
Apart from the obvious drawbacks of hardcoding, the drawback here was
that, if we subtracted 2 frames (instead of 2.6) from the target running
time, we'd request the next keyframe a bit too far into the future,
which would make our files split at the wrong position.

0432826950 matroska: Add the WebM encrypted content support in matroskademux
This commit:

1. Reads the WebM and Matroska ContentEncryption subelements.

2. Creates a GST_PROTECTION event for each ContentEncryption, which
   will be sent before pushing the first source buffer.
   The DRM system id field in this event is set to GST_PROTECTION_UNSPECIFIED_SYSTEM_ID,
   because it isn't specified neither by Matroska nor by the WebM spec.

3. Reads the protection information of encrypted Block/SimpleBlock and
   extracts the IV and the partitioning format (subsamples).

4. Creates the metadata protection for each encrypted Block/SimpleBlock,
   with those informations: KeyID (extracted from ContentEncryption element),
   IV and partitioning format.

5. Adds a new caps for WebM encrypted content named "application/x-webm-enc",
   with the following new fields:

   "encryption-algorithm": The encryption algorithm used.
                           values: "None", "DES", "3DES", "Twofish", "Blowfish", "AES".

   "encoding-scope": The field that describes which Elements have been modified.
                     Values: "frame", "codec-data", "next-content".

   "cipher-mode": The cipher mode used in the encryption.
                  Values: "None", "CTR".

7ceefec714 matroskademux: Emit no-more-pads after parsing Tracks
Currently matroskademux does not emit no-more-pads until the first
Cluster is parsed, even though the Tracks have already been parsed and
from that point on there can be no more tracks.

This is important in MSE because the browser needs to know when the MSE
initialization segment has been completely parsed so that it can expose
the tracks to the user. Some applications depend on this been done
before they feed frames to the demuxer.

As a consequence, historically WebKit has relied on hacks such as
listening to the `pad-added` event, which made impossible to support
multiple tracks in the same file. Let's fix that.
