1f3ef7aa01 basetransform: Do not check if NULL is an emtpy caps
gst_base_transform_transform_caps can return NULL in various conditions
thus we should not treat its result as valid caps.

In all other places NULL is properly handled.

a7f9c80220 basesink: Add processing deadline
The processing deadline is the acceptable amount of time to process the media
in a live pipeline before it reaches the sink. This is on top of the algorithmic
latency that is normally reported by the latency query. This should make
pipelines such as "v4lsrc ! xvimagesink" not claim that all frames are late
in the QoS events. Ideally, this should replace max_lateness for most applications.

d34f046029 baseparse: Ensure seqnum consistency
We need all relevant events of a segment to have consistent seqnum:
* GST_EVENT_SEGMENT
* GST_EVENT_EOS

If we are push-based and create a new segment, use the same seqnum
as the upstream event.

If we are pull-based, use the seqnum of that newly created segment
event everywhere

80dfb7bb3f gst: Use memcpy() instead of strncpy() where appropriate
strncpy() is assumed to be for strings so the compiler assumes that
it will need an extra byte for the string-terminaning NULL.

For cases where we know it's actually "binary" data, just copy it
with memcpy.

12c5d903c9 basesrc: No need to stop flushing in start_complete
The flushing state is handled a bit differently, there is no need
to stop flushing in start_complete. This would other result in
unlock_stop being called without unlock_start.

Unlike what the old comment says, there is no need to take the live
lock here, we are still single threaded at this point (app thread
or the state change thread). Also, we will wait for playing state
in create/getrange, no need to do that twice.

65dcb2adbf gstbasesink: Include segment.offset in the computation of position
Position queries with GST_FORMAT_TIME are supposed to return stream
time.

gst_base_sink_get_position() estimates the current stream time on its
own instead of using gst_segment_to_stream_time(), but the algorithm
used was not taking segment.offset into account, resulting in invalid
values when this field was set to a non-zero value.

443221c661 basetransform: Allow going passthrough inside decide_allocation
Sub-class may want to decide to go passthrough/in-place by inspecting
the support meta APIs. This patch duplicates the check for this mode,
so we still don't do uneeded allocation query while we allow sub-classes
to switch the behaviour during it's own decide_allocation call.

Notice that such sub-class need to reset the class to non-passthrough in
set_caps() in order for decide_allocation to be called again. This is
needed otherwise we'd be doing an allocation query in element in which
it make no sense (notably capsfilter).

Tim-Philipp Müller
18fe36a286 basesrc: add buffer list support
Add a gst_base_src_submit_buffer_list() function that allows subclasses
to produce a bufferlist containing multiple buffers in the ::create()
function. The buffers in the buffer list will then also be pushed out
in one go as a GstBufferList. This can reduce push overhead
significantly for sources with packetised inputs (such as udpsrc)
in high-throughput scenarios.

The _submit_buffer_list() approach was chosen because it is fairly
straight-forward, backwards-compatible, bindings-friendly (as opposed
to e.g. making the create function return a mini object instead),
and it allows the subclass maximum control: the subclass can decide
dynamically at runtime whether to return a list or a single buffer
(which would be messier if we added a create_list virtual method).

Validated with the tests and gst-launch-1.0 pipelines.

45cef5726f aggregator: rename a local variable
The variable tracks wheter the queue is not empty, but num_buffers==0. That
means we have events or queries to process. Rename accordingly.

4808f4836c aggregator: cleanup event forwarding
Don't copy the whole event struct. Set the input params when we call the
forwarding helper. Initialize the internal fields and return values in the
helper.

a82e6bc650 aggregator: simplify src_event
Avoid extra ref/unref, we have a ref and do_seek unrefs. Just return the result
as we have. This lets us remove the local var plus the label.
