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 ensure that pads have caps when they are exposed, do
the exposing when all pending streams have prerolled an
output buffer, and only then EOS and remove any old pads.
Improves the switching sequence by making caps available
as soon as a pad appears.

Unless the video format has an alpha component (ARGB, ...), set the
video_surface opaque.
In the usual case where the black area_surface has the same size as the
video_surface (eg: run gst-play-1.0 video.mp4), this makes the black
surface totally occluded which makes weston compositor's life easier
since it can ignore that surface.
Also unconditionally set the black area_surface opaque.

and error out here already otherwise. We currently don't support
reconfiguration here and it can't happen really either unless the auto
mode is selected.
Otherwise the destructor will never be called, and we would have to call
the constructors manually at some point... which we never did, so
calling release() on it before it got otherwise initialized caused a
crash. For example when running gst-inspect-1.0.
Vulkan handles are either pointers (64-bit) or 64-bit integer
handles (32-bit). Cast the type in failure cases.

send_event() of parent class (i.e., GstBinClass) iterates srcpads
to send SEEK event. And performing it per srcpad is inefficient.
So, let's drop duplicated SEEK event by checking seqnum

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."
https://bugzilla.gnome.org/show_bug.cgi?id=777682
hls live starts playback from the allowed latest fragment,
but its "sequence position" is set to zero, and so stream
time is also set to zero.
This does not make sense, because hls live allows seeking to past position,
and it's negative stream time from downstream element's point of view.
Note that, allowed seekable range (and seeking query) is
from the first fragment of playlist to the allowed latest fragment.

HLS spec 6.3.3 is saying that
"the client SHOULD NOT choose a segment which starts less than
three target durations from the end of the Playlist file."
To ensure above statement, the third fragment from the end of playlist
should be excluded from seekable range and also from available starting fragment.
(i.e., the fourth fragment from end of playlist is the starting fragment).
https://bugzilla.gnome.org/show_bug.cgi?id=777682
During live playback, the first fragment in a updated
playlist can be advanced from that of startup playlist.
Meanwhile, since hlsdemux finds target seek position
by just accumulating fragment's duration, the base should
be adjusted to the updated first fragment's timestamp.

In some places a GST_FLOW_FLUSHING result was return as a FALSE
gboolean and then returned from a parent function as
GST_FLOW_ERROR. This prevented seeking from working.

Without failing, we would play back random parts of the stream which is
arguably a worse user experience, and failing is also recommended by the
spec here.
And also handle live streams without any media sequence numbers at all
properly, that is, make sure the sequence numbers are increasing instead
of starting again at 0 every time.
