SDP's are generated and consumed according to the W3C PeerConnection API
available from https://www.w3.org/TR/webrtc/
The SDP is either created initially from the connected
sink pads/attached transceivers as in the case of generating an offer or
intersected with the connected sink pads/attached transceivers as in
the case for creating an answer. In both cases, the rtp payloaded streams
sent by the peer are exposed as separate src pads.
The implementation supports trickle ICE, RTCP muxing, reduced size RTCP.

Try prioritizing downstream's caps over upstream's if possible so the
parser can configured in "passthrough" if possible and save it from
doing useless conversions.

Unfortunately we need to use an extra set of parenthesis for each data level.
For details see:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53119
Affected versions are e.g.
gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4
which is the default on ubuntu-trusty. I looks like the fix was never
backported.
Remove gst_init() from a few tests. Use _OBJECT variants in logging. Remove
arbitrary extra blank lines. Make push_event() more like push_buffer() - set
the event to NULL and add cleanup to _chain_data_clear().
Using two (or more) probes on the same pad where one of the probe
returns HANDLED or DROP is tricky since the other probes might
not be called.
Instead use regular probes and a proper pad (the sinkpad already existed,
it only required to be activated and have a dummy chain function for
the events/buffers to be received/handled properly)
In most cases we want to stop the pipeline just once, but we have
to do this from code that runs in the streaming threads and in case
we have multiple streams, we need to make sure that we do this only
once. The previous checks were broken, this should fix it.

Except for gst/gl/gstglfuncs.h
It is up to the client app to include these headers.
It is coherent with the fact that gstreamer-gl.pc does not
require any egl.pc/gles.pc. I.e. it is the responsability
of the app to search these headers within its build setup.
For example gstreamer-vaapi includes explicitly EGL/egl.h
and search for it in its configure.ac.
For example with this patch, if an app includes the headers
gst/gl/egl/gstglcontext_egl.h
gst/gl/egl/gstgldisplay_egl.h
gst/gl/egl/gstglmemoryegl.h
it will *no longer* automatically include EGL/egl.h and GLES2/gl2.h.
Which is good because the app might want to use the gstgl api only
without the need to bother about gl headers.
Also added a test: cd tests/check && make libs/gstglheaders.check
https://bugzilla.gnome.org/show_bug.cgi?id=784779
Sending an event can accepted event if the caps were rejected
because the event could be queued and processed later.
Also send a drain query in the caps test to make sure that the
event has been processed.

Since insertion of aud landed, we need to change some testcases
accroding to the change.
Note that counting frames are changed in parser.c,
due to generated frames, AUD.

For duration queries on live streams, adaptivedemux ignores the query.
The problem then is that the query is answered by the downstream
qtdemux element, with the duration of the currently passing fragment.
This commit changes the behaviour of adaptivedemux to answer the duration
queries for live streams, returning GST_CLOCK_TIME_NONE.

This would ideally be solved in baseparse but that requires further
thought at this point, and in the meantime it would be good to have
rawbaseparse not assert on this but handle it gracefully instead.
Make the unit tests handle the fact that pads don't appear
immediately. Before, the test assumed pads are exposed before the
internal source element is created, which is no longer true.
To satisfy follwing restriction of HLS spec 6.3.3,
select startup fragment sequence to 4th from end of playlist.
Also, seek range should exclude last three fragment in playlist.
"the client SHOULD NOT choose a segment which starts less than
three target durations from the end of the Playlist file."

If they were not ported after 4+ years it seems unlikely that anybody is
ever going to need them again. They're still in the GIT history if
needed.

This was used by MSN messenger in prehistoric times, it's safe
to say no one needs or wants this any more these days. For
decoding old recordings there's still a decoder in ffmpeg.

Section 5.3.3 in ISO/IEC 23009-1:2014 defines that invalid references
(e.g., invalide URI or cannot be resolved) specified by "@xlink:href" attribute
shall be removed. That means, we should play it without error,
and just ignore the corresponding element.
It's similar to "urn:mpeg:dash:resolve-to-zero:2013".

pnm: add misssing continuation slash at end of line
vp8parser: no need to link codecparsers twice
dash_demux, mssdemux, hlsdemux: fix lib/flags ordering - local
libs and flags must come first, then base before core before rest
Create our own instead as the default framebuffer may require special
fiddling (like having a visible window) to correctly display/be renderable.
Fixes the remaining GL library tests on OS X
External xml could have empty, one or multiple top-level "Period" elements.
Because xml parser cannot parse the multiple top-level elements
(i.e., no root element), we need to wrap a xml in order to make root element.

PlayReady being the one of the few DRM formats encoding its data with
base64 it was not consistent to have a special case for this. So the
base64 decoding operation now needs to be done by the protection event
consumer, if needed.
https://bugzilla.gnome.org/show_bug.cgi?id=774112
The spec allows the core/compatibility profiles to be used
with #version 150.
Also tighten up the tests to check for default profiles being chosen
correctly.
The linker flags for several plugins (dashdemux, mssdemux, hlsdemux) are missing
$(GST_PLUGINS_BASE_LIBS), so add them so they can find -lgsttag and -lgstapp.

The tests were broken since 91fea30, which changed glupload to return
GST_GL_UPLOAD_RECONFIGURE if the texture target in the input buffers doesn't
match the texture-target configured in the output caps.
This commit fixes that and adds more checks for the new behaviour.
It uses random data streams but dashdemux nowadays actually looks into the
streams and doesn't like randomness very much. The tests should probably just
become validate tests on real streams.
https://bugzilla.gnome.org/show_bug.cgi?id=769553
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.
https://bugzilla.gnome.org/show_bug.cgi?id=753751
Facilities are given to create fbo's and attach GL memory (renderbuffers
or textures). It also keeps track of the renderable size for use with
effective use with glViewport().
Rather than assuming something. e.g. zerocopy on iOS with GLES3 requires
the use of Luminance/Luminance Alpha formats and does not work with
Red/RG textures.
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.

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
As is done everywhere else.
From what I can gather from make -C tests/check V=1 $(GST_PLUGINS_BAD_CFLAGS) is
required in order to find in-tree headers as well as srcdir != builddir
configurations.
With e38af23044 returning the correct contexts,
gst_gl_display_add_context() was susceptible to causing infinte loops when
adding the same GstGLContext more than once. Fix and add a test for
gst_gl_display_add_context().
Fixes glvideomixer gst-validate tests.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=762684
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
Some operations are unnecessary when running with only a single GL
context.
e.g. glFlush when setting a fence object as the flush happens on wait.
API: gst_gl_context_is_shared
In very few cases the simple version was actually needed and having the
parameters hidden by a _full() version caused application that actually needed
it to not use it.
