Add a test of the gst_mpd_client_get_maximum_segment_duration() function
to check that it first checks the MPD@maxSegmentDuration and then falls
back to checking all of the segment durations.

When the test involves doing a seek, only check for data size after
the seek. The final segment range after seek might be different/smaller
than the threshold for doing the seek and doing the check before
seeking would fail.
Following the Don't Repeat Yourself principle, define macros
for the structures that contain the request and response headers,
so that the name is not repeated in multiple places in multiple files.

Test content protection
Configure 3 content protection sources:
- a uuid scheme/value pair
- a non uuid scheme/value pair (dash recognises only uuid schemes)
- a complex uuid scheme, with trailing spaces and capital letters in scheme uri
Only the uuid scheme should be recognised. We expect to receive 2 content protection events

Test header download error.
Let the adaptive demux download a few bytes, then instruct the
GstTestHTTPSrc element to generate an error while the fragment header
is still being downloaded.
https://bugzilla.gnome.org/show_bug.cgi?id=762144
Moved testQuery after testFragmentDownloadError so that testDownloadError
and testFragmentDownloadError are grouped together.
The commit just moved the testQueryCheckDataReceived and
GST_START_TEST (testQuery) functions but git gets confused in matching the
lines and reports a lot of changes in the patch.
https://bugzilla.gnome.org/show_bug.cgi?id=762144
To allow the adaptivedemux live stream tests to run in non-realtime, use a
GstTestClock as the system clock. This allows the unit tests to complete
more quickly than if they had to complete in real time.
https://bugzilla.gnome.org/show_bug.cgi?id=762147
Deallocate GObject* with g_object_unref instead of gst_object_unref.
Even if it works now, it is confusing and in the future it might
not work if any GstObject specifics are added.
https://bugzilla.gnome.org/show_bug.cgi?id=762142
When the start_type is GST_SEEK_TYPE_NONE for a forward seek
(or stop_type for a reverse) is not set on a snap seeking operation,
the element should use the current position and then snap as requested.
Also fixes uninitialized variable complaint by clang about
'ts' variable.
All hlsdemux tests create a GstStructure called "state" that can be used
by test cases to store information during a test. The name of this
structure is arbitrary. When the code was written, the intention was
to use the name of the test, to aid debugging. However, during
development this was lost, so that the state GstStructure is always
given the name "setup_test_variables".
This commit changes this so that the name of the test is used.

The default one is 6 minutes, the test was using 5 minutes so just
resort to using the default.
For the non-valgrind test also use the default 20 secs instead of
reducing it to 6s. No real reason to set a custom value here.
When caps are already negotiated it should be possible to
select formats other than the one that was negotiated. If downstream
allows alpha video caps and it has already negotiated to a non-alpha
format, caps queries should still return the alpha caps as a possible
format as caps renegotiation can happen.
Includes tests (for compositor) to check that caps queries done after
a caps has been negotiated returns complete results

The function actually returns the segment availability start time (as defined by the standard).
That is at the end of the segment, but it is called availability start time.
Availability end time is something else (the time when the segment is no longer
available on the server). The function name was misleading.
https://bugzilla.gnome.org/show_bug.cgi?id=757655
The demux_sent_eos callback is unused in tests. It was also registered on
a wrong pad, so it actually triggered when demux received eos from a
fragment download.
https://bugzilla.gnome.org/show_bug.cgi?id=760328
Adds unit tests similar to the ones that we have for DASH and HLS.
Tests:
* manifest parsing finishes successfully
* some queries (duration, seekable, latency)
* seeking with various values and flags
Similar to HLS but DASH has the extra issue that it can have
multiple streams so snapping can be tricky as streams usually
won't be aligned.
For now, those tests handle the case of only having a single
stream.
https://bugzilla.gnome.org/show_bug.cgi?id=759158
Handling the ghostpad and its internal pad was causing more issues
than helping because of their coupled activation/deactivation
actions.
As we have to install custom chain,event and query functions it is
better to use a floating sink pad internally in the demuxer and just
use those pad functions to push through a standard pad in the demuxer
https://bugzilla.gnome.org/show_bug.cgi?id=757951
The URI attribute from the EXT-X-KEY tag and the URI attribute from the
EXT-X-I-FRAMES-ONLY tag are both quoted-string attibutes that have their
quotation marks removed during parsing. The CODECS attribute of the
EXT-X-STREAM-INF is also a quoted-string attribute, but this attribute
was not being un-quoted.
This commit changes the parser to always unquote all quoted-string
attributes and adjusts the unit tests to this new bevahiour for the
CODECS attribute.
An additional test is added to check that parsing of all of the fields
in the EXT-X-STREAM tag is correct, including those that contain comma
characters.

Using the new GstAdaptiveDemux test framework, add tests that
exercise hlsdemux. The following tests are added:
simpleTest
A simple playlist that contains some media URLs
testMediaPlaylist
A master playlist with a variant playlist that contains media URLs
testMediaPlaylistNotFound
A master playlist that points to a missing variant playlist
testFragmentNotFound
A master playlist with a variant playlist that contains media URLs
There is a missing media file referenced from the variant playlist.
testFragmentDownloadError
A master playlist with a variant playlist that contains media URLs
During the download of one media file, the test simulates the network
connection being dropped.
testSeek
A simple test of trying to perform a seek on an HLS stream.
To allow code from dash_demux.c to be used by other elements
that are based upon GstAdaptiveDemux, the code has been
refactored into four new files:
adaptive_demux_engine.[ch]
adaptive_demux_common.[ch]
The code in adaptive_demux_engine.c provides a generic
test engine for elements based upon GstAdaptiveDemux.
The code in adaptive_demux_common.c provides a set
of utility functions that are common between the tests
for hlsdemux and dashdemux.
As part of the refactoring, variables in structures were
renamed from using camelCase to underscore_case to match other
GStreamer source code.
The fake_http_src was renamed test_http_src and changed to use
callbacks to provide input data and error conditions. Rather than
using an array of input data that tries to encode all the
possible use cases for the GstTestHTTPSrc element, use a struct of
callbacks.
Users of this element are obliged to implement at least the src_start
callback, which provides a way to link from a URI to the settings
for that URI.
gst_mpdparser_parse_utctiming_node does not validate the parsed values completely. The following scenarios are incorrectly accepted:
- elements with no schemeIdUri property should be rejected
- elements with unrecognized UTCTiming scheme should be rejected
- elements with empty values should be rejected
The last one triggers a division by 0 in gst_dash_demux_poll_clock_drift:
clock_drift->selected_url = clock_drift->selected_url % g_strv_length (urls);
because it urls is a valid pointer to an empty array.

The videoframe-audiolevel element acts like a synchronized audio/video "level"
element. For each video frame, it posts a level-style message containing the
RMS value of the corresponding audio frames. This element needs both video and
audio to pass through it. Furthermore, it needs a queue after its video
source.
https://bugzilla.gnome.org/show_bug.cgi?id=748259
This no longer does anything, and it was marked as CONSTRUCT_ONLY
which means someone would really have to go out of their way to
be able to set this, which would only be done in very custom
scenarios, if ever, and those will likely target a specific
version of GStreamer then, so probably not much point keeping
it deprecated for a while before removing it.
The Onvif Streaming Specification specifies that the NTP timestamps
in the Onvif extension header indicaes the absolute UTC time associated
with the access unit. But by using running time we can not achieve that,
since a frame's running time depends on the played interval, whether a
non-flushing is done, etc. Instead we have to use the stream time.
https://bugzilla.gnome.org/show_bug.cgi?id=757688
It is now possible to update the currently used ntp-offset with a
custom serialized downstream event. The element will read the ntp-offset
property when doing the state transition from READY to PAUSED and
use that offset until it receives a "GstNtpOffset" event, which also
has a "ntp-offset" attribute in that it's structure. In case the
property is not set and no event has been received, the element will
guess the npt-offset with help of the clock. If no clock can be
retrieved, the element will error out and stop the data flow.
The same event is also used for updating the D/E-bits in the RTP
extension header. The discont flag in a buffer can be set whenver a
live/network source looses a frame, but that is not the type of
discontinuity that the onvif extension header should reflect. The
header is mainly used for playback of a track concept, in which
gaps can be present, and it's those kind of gaps that should be
highlighted with the D- and E-bits.
https://bugzilla.gnome.org/show_bug.cgi?id=757688
If a buffer or a buffer list is cached, no events serialized with the
data stream should get through. The cached buffers and events should
be purged when we stop flushing.
https://bugzilla.gnome.org/show_bug.cgi?id=757688
Split the unit tests for rtponviftimestamp and rtponvifparse
elements in separate files.
Setup and cleanup the element and pads in fixures. Make the tests work
with CK_FORK=no as well, by cleaning up the 'buffers' list when needed.
Make unit tests work when run in valgrind by unreffing all buffers,
and by not allocating any payload in RTP buffers. Since we're not
doing anything with the payload part, but we're memcmp-aring the
complete buffer memory, valgrind complained about non-initialized
memory being used.
https://bugzilla.gnome.org/show_bug.cgi?id=757688
The standard does not seem to make any particular explicit not
implicit reference to the signedness of durations, and the code
does not rely on such, nor on the negativity of the -1 value
that's used as a placeholder when a duration property is not
present in the XML.
https://bugzilla.gnome.org/show_bug.cgi?id=750847
According to the standard:
"SegmentBase, SegmentTemplate and SegmentList shall inherit
attributes and elements from the same element on a higher level.
If the same attribute or element is present on both levels,
the one on the lower level shall take precedence over the one
on the higher level."
gst_mpdparser_parse_segment_list_node will now discard any inherited
segment URLs if the parsed element defines some too.
