Setting the seek flags to GST_SEEK_FLAG_SNAP_* will change the seek
target time to a segment boundary.

Dashdemux has set the width and height information from MPD manifest.
Some embedded devices which are not insufficient H/W resources need more information such as framerate
to assign H/W resources. So I suggested that dashdemux also needs to set the framerate information from MDP manifest.

As HLS does not provide any way of knowing the server's clock, and we do
buffering of "live" streams, at some point we will fall behind the server in
many cases and would have to advance to a fragment that is not in the playlist
anymore.
Previously we would've just resynced to the next oldest fragment that is still
there, but this causes problems as from this point onwards we would always
fall off the playlist again all the time.
Instead we now resync and move to the 3rd newest fragment like we would do
when starting playback of a live stream.

If connection speed is set, playlist according
to connection speed is selected as current playlist.
Problem is that the current variant of main playlist still
points to previously set variant.
If previously set variant doesn't correspond to current
playlist, then it causes unnecessary change of playlist
to the same playlist after first fragment is downloaded,
because of not updated current variant.
To fix this, we need to make sure that current variant
of main playlist corresponds to the current playlist

Don't jump backward to 3 files from the end of the playlist
when switching variants - it just means we downloaded
fragments fast and caught up to the end of the playlist.
Disable that by treating a variant switch as a playlist
update, not a restart due to a seek or so.
If the stream is discont, we must provide a timestamp in any case. Elements
like tsdemux are not going to output anything if we give a NONE timestamp
after a discont.
Also marking a stream as discont if a playlist change was not successful would
lead to the above situation, but in that case we are not required at all to
mark the stream discont as we're still at the old playlist.
commit da5c41930c removed the two uses of the
new value of data:
channels = opus_packet_get_nb_channels (data);
bandwidth = opus_packet_get_bandwidth (data);
Since then, data isn't being used between incrementing it by packet_offset
and going out of scope. Removing this uneeded statement.
The scene graph can be initialized when the we receive window handle change
notification and so we will not receive a scenegraph initialization
notification. Initialize ourself in this case.

The result of the two expressions will be promoted to guint64 anyway,
perform all the arithmetic in 64 bits to avoid potential overflows.

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.

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.
