The result of the two expressions will be promoted to guint64 anyway,
perform all the arithmetic in 64 bits to avoid potential overflows.
CID 1338690, CID 1338691
sample_rate might be used uninitialized if !sink_caps is TRUE. Initialize
it to the default used in gst_codec_utils_opus_parse_caps () when there is
no rate defined in the caps.
CID 1338695
There is a possibility that the _get_caps impl will be called with the
feature in the filter caps which when interecting with the template,
will return EMPTY and therefore fail negotiation.

It's for the upstream element driving the pipeline to
handle seeks and send flush events or not, filters
should not interfere here, otherwise downstream pads
could be flushing before upstream pads are flushing,
which can result in GST_FLOW_ERROR being sent instead
of GST_FLOW_FLUSHING when trying to forward sticky
events at just the wrong moment.
No need to use G_GINT64_FORMAT for potentially negative values of
GstClockTimeDiff. Since 1.6 these can be handled with GST_STIME_FORMAT.
Plus it creates more readable values in the logs.

We always require the channel-mapping-field. If it's 0 we require nothing
else, otherwise we need channels, stream-count and coupled count to be
available.
oggdemux is outputting the meta now, and only outputs if it should really
apply to the current buffer. Previously we would skip N samples also if we
started the decoder in the middle of the stream.

It is doing the wrong thing because of the Opus pre-skip: while the timestamps
are shifted by the pre-skip, the granule positions are not shifted.
oggmux is doing the right thing here already.

The first frame has lookahead less samples, the last frame might have some
padding or we might have to encode another frame of silence to get all our
input into the encoded data.
This is because of a) the lookahead at the beginning of the encoding, which
shifts all data by that amount of samples and b) the padding needed to fill
the very last frame completely.
Ideally we would use LPC to calculate something better than silence for the
padding to make the encoding as smooth as possible.
With this we get exactly the same amount of samples again in an
opusenc ! opusdec pipeline.

Waylandsink needs exception code in gst_wayland_sink_set_window_handle().
After making sink->window, User can call
gst_wayland_sink_set_window_handle(). It is the user's fault, but
Waylandsink needs to handle the exception, if not then sink->window is
changed and rendering fails.

Waylandsink needs exception code in gst_wayland_sink_set_context(). After
calling gst_wayland_sink_set_context(), below code is set.
GST_ELEMENT_CLASS (parent_class)->set_context (element, context); but, If
user can call onemore. It is user's fault. but waylandsink need to
exception.

The stream->cur_seg_template is set to the lowest available segment
template (representation or adaptation or period, in this order).
Because the template elements are inherited, the lowest template will
have all the elements the parents had, so there is no need to check the
parent for an element that is not found in the child (eg initialisation
or index).

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.

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.

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.
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.

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.
