There are streams out there that consistently contain garbage between
every frame so we never ever find a second consecutive syncword.

See https://bugzilla.gnome.org/show_bug.cgi?id=738237

Fixes multipass encoding when re-using the same element/pipeline
for subsequent encoding runs.

Some files may provide different caps insight of one stream. Since
vp9enc support caps reinit, we should support cache reinit too.
If more then file cache file will be created, the naming will be:
cache cache.1 cache.2 ...

The accept-caps query just does a shallow check at the current
element while at this test we want it to also look at downstream.
So use caps query there.

https://bugzilla.gnome.org/show_bug.cgi?id=753623

Do a quick check with the pad template caps as it is enough. Users
should have figured the appropriate full caps on a previous caps query

Sometimes it is useful to know this information on the
server side. Other popular implementations (vlc, ffmpeg, ...)
also send this header on every message.

This includes a new "user-agent" property that the user
can set to use a custom User-Agent string. The default
is "GStreamer/<version>"

https://bugzilla.gnome.org/show_bug.cgi?id=750101

This will allow adding common request initialization, like the
user agent string, in just one place.

Use constantDuration to calculate the timestamp of non-first AU in the
RTP packet.

If constantDuration is not present in the MIME parameters, its value
must be calculated based on the timing information from two consecutive
RTP packets with AU-Index equal to 0.

To allow souphttpsrc to be use HTTP methods other than GET
(e.g. HEAD), add a "method" property that is a string. If this
property is not set, GET is used.

Makes it easier to differentiate from other modules states unit test

This is a problem when statically linking.

Otherwise we will just output buffers without timestamps after a reset if no
timestamps are provided by upstream, e.g. when using RTSP over TCP.

The payloader didn't copy anything so far, the depayloader copied every
possible meta. Let's make it consistent and just copy all metas without
tags or with only the video tag.

The doc generator isn't happy when we have class name clash. Simply
use it's own namespace.

unused local variable 'delay' is removed.

This commit adds support for ISOBMFF Common Encryption (cenc), as
defined in ISO/IEC 23001-7. It uses a GstProtection event to
pass the contents of PSSH boxes to downstream decryptor elements
and attached GstProtectionMeta to each sample.

The default behaviour was changed in the 0.10 -> 1.x
transition, but the comment was not updated.

rtptheorapay: Extract pixel format from the ident header to put it into the sampling field of the caps

We always put 4:2:0 into the caps before, which obviously is wrong for 4:2:2
and 4:4:4 formats.

GstRTSPMedia uses this classification to detect the real payloader
inside a dynpay bin and asserts if it doesn't find it, therefore
it is required

https://bugzilla.gnome.org/show_bug.cgi?id=753325

1) Tests that using dynamic PT instead of the default ones work
2) If we ever decide to change the codec here we don't need to
   worry about change the PT for the default one of the new codec
   in the test

https://bugzilla.gnome.org/show_bug.cgi?id=746445

https://bugzilla.gnome.org/show_bug.cgi?id=746445

Initialize the PT to the default value of the codec and check if
it is still the default before declaring the pt to be dynamic or
not when setting the caps.

Also use the PT constants from the rtp lib when possible

https://bugzilla.gnome.org/show_bug.cgi?id=747965

It will be used in some cases for getting the correct offsets
from trun atoms.

Handle the flag from the tfhd that signals the base offset to
start from the moof atom

The RTP PT for alaw is 8.
Less than 50 packets are received in the length of this test so it
would never drop a buffer or would drop only the last buffer and
it would fail sometimes when the received wouldn't receive the
retransmission packet in time.

https://bugzilla.gnome.org/show_bug.cgi?id=746445

We need a proper caps event from upstream with the full RTP caps as we can't
create caps ourselves from thin air. Fixes usage of rtpstreamdepay after e.g.
a filesrc or any other element that supports pull mode.
