7c495b711e opusparse: initialize sample rate to a default
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.

eb4e2de4e8 gtk: add the overlaycomposition feature to the template caps
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.

63853b7b0d assrender: don't send flush events on seeks
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.

5a4c09f791 resindvd: use GST_STIME_FORMAT for GstClockTimeDiff
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.

483cb05af1 opusenc: Disable granule position calculations by the base class
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.

f66afc47ac opusenc: Encode exactly the amount of samples we got as input and put correct timestamps on it
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().

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

19d604e92f dashdemux: remove unreachable code
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).

e48e68416c mpdparser: make durations unsigned where appropriate
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.

013655d886 dashdemux: inherited segment URLs are ignored if they are defined again in a lower SegmentList
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.

c8ef39cac7 dashdemux: provide a default suggestedPresentationDelay
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").
