This was chosen over relying solely on the caps as glupload needs to propose an
allocation and set the texture target based on the output caps. Setting the
caps in the config is currently pointless as they are overwritten in a lot of
element's decide_allocation functions.
This provides a mechanism for the buffer pool to be configured for a certain
texture target when none has been configured.
Solved with a simple shader templating mechanism and string replacements
of the necessary sampler types/texture accesses and texture coordinate
mangling for rectangular and external-oes textures.
Add the various tokens/strings for the differnet texture types (2D, rect, oes)
Changes the GLmemory api to include the GstGLTextureTarget in all relevant
functions.
Update the relevant caps/templates for 2D only textures.
Created a unit test for dashdemux. It relies on a fake SOUP HTTP src plugin
that will feed data to dashdemux. The test controls the data to be
generated and checks the correct data was received for each expected
stream.

If MPD@suggestedPresentationDelay is not present in the manifest,
dashdemux selects the fragment closest to the most recently generated
fragment. This causes a playback issue because this choice does not allow
the DASH client to build up any buffer of downloaded fragments without
pausing playback. This is because by definition new fragments appear on
the server in real-time (e.g. if segment duration is 4 seconds, a new
fragment will appear on the server every 4 seconds). If the starting
playback position was n*segmentDuration seconds behind "now", the DASH
client could download up to 'n' fragments faster than realtime before it
reached the point where it needed to wait for fragments to appear on the
server.
The MPD@suggestedPresentationDelay attribute allows a content publisher
to provide a suggested starting position that is behind the current
"live" position.
If the MPD@suggestedPresentationDelay attribute is not present, provide
a suitable default value as a property of the dashdemux element. To
allow the default presentation delay to be specified either using
fragments or seconds, the property is a string that contains a number
and a unit (e.g. "10 seconds", "4 fragments", "2500ms").
Corrected the parsing of a segment template string.
Added unit tests to test the segment template parsing.
All reported problems are now correctly handled.

The gst_adaptive_demux_stream_free function is trying to stop the stream's
download task. For this, it signals the task. But it fails to also set the
stream->download_finished = TRUE, so the task will go back to sleep and
only exit when the download is finished.

When building the media segment list using a SegmentList node, the
gst_mpd_client_setup_representation function will iterate through the
list of S nodes and will expect to find a matching SegmentUrl node. If
one does not exist, the code made an illegal memory access.

These are used to apply restrictions on what the MPD file may
use, so no profile means no restrictions.
Besides, nothing actually uses the profiles (yet) anyway.

Initialize to 0 these parse structures before filling them: GstH264SEIMessage,
GstH264NalUnit, GstH264PPS, GstH264SPS and GstH264SliceHdr.
When calling the functions which fill those structures, they may fail, leaving
unitialized those structures. This situation may lead to future problems, such
as a segmentation fault when freeing, for example.
This patch initializes to zero these structures, before filling them.

Otherwise those symbols can conflict with external libraries when
linking everything statically for mobile targets.
Use the gst_gm_ prefix, short for gst geometric math.

This wl_display proxy is temporary only until waylandsink goes NULL,
at which point the connection to the display is disposed. Unfortunately,
if this is advertised as a GstContext, playbin will cache it and re-feed
it to the sink when it goes PLAYING again, but the wl_display pointer
will at that point be invalid and cause a crash.
Another solution to the problem would be to also cache the GstWlDisplay
object inside the GstContext, which would automatically ref-count
the display connection, but I see no reason in doing that at the moment,
as there are no known users of this GstContext outside waylandsink.
It's probably better to avoid chasing hidden refcounts.

the USING_GLES2 includes all GLES3 contexts as well which does support
drawing to multiple buffers. Instead make or decision solely based on
whether glDrawBuffers is available or not.
If a (master) playlist contains a variant list entry without a
URI then during parsing of the next variant list entry we are
a) leaking the entry we're currently parsing (new_list), and
b) free'ing the pointer to the previous list entry (list) without
updating the pointer.
Hence when then adding the URI for the latest parsed entry, incorrect
information is stored, as the information is used from 'list' which
is not valid memory anymore, also leading to crashes.
Fix this by correctly storing the new variant list entry pointer
as needed.

Nicer to read, two lines of code less, and also the callback
function should've been a GCompareFunc that returns a gint
and not a boolean (it did work correctly, was just confusing).
