0934af6cce videoaggregator: Don't wait if input buffer is after output
If the input buffer is after the end of the output buffer, then waiting
for more data won't help. We will never get an input buffer for this point.

This fixes compositing of streams from rtspsrc.

cf6a36721b videoaggregator: properly handle interlace-mode restrictions
videoaggregator can't handle interlace-mode changes so it must
always restrict itself to the first interlacing mode it receives.

We weren't using the result of find_best_format at all.

Also, move the find_best_format usage to the default update_caps() to make

86d21e9455 videoaggregator: fix caps queries to allow proper renegotiation
When caps are already negotiated it should be possible to
select formats other than the one that was negotiated. If downstream
allows alpha video caps and it has already negotiated to a non-alpha
format, caps queries should still return the alpha caps as a possible
format as caps renegotiation can happen.

Includes tests (for compositor) to check that caps queries done after
a caps has been negotiated returns complete results

f1323fb6df videoaggregator: don't do caps processing that is not overridable
Allows the subclass to completely override the chosen src caps.

This is needed as videoaggregator generally has no idea exactly
what operation is being performed.

- Adds a fixate_caps vfunc for fixation
- Merges gst_video_aggregator_update_converters() into
  gst_videoaggregator_update_src_caps() as we need some of its info
  for proper caps handling.
- Pass the downstream caps to the update_caps vfunc

895e71e810 videoaggregator: Fix mixup of running times and segment positions
We have to queue buffers based on their running time, not based on
the segment position.

Also return running time from GstAggregator::get_next_time() instead of
a segment position, as required by the API.

Also only update the segment position after we pushed a buffer, otherwise
we're going to push down a segment event with the next position already.

ac503aee7d videoaggregator: fix caps query to properly handle alpha formats
Only accept alpha if downstream has alpha as well. It could
theoretically accept alpha unconditionally if blending is
properly implemented for handle it but at the moment this
is a missing feature.

Improves the caps query by also comparing with the template
caps to filter by what the subclass supports.

fc49a1b508 videoaggregator: simplifies and improves sink_get_caps.
The problem here was that after removing the formats and
all the things we could convert, we then intersected these
caps with the template caps.

Hence if a subclass offered permissive sink templates
(eg all the possible formats videoconvert handles), but only
one output format, then at negotiation time getcaps returned
caps with the format restricted to that format, even though
we do handle conversion.

86705fbbca videoaggregator: add "ignore-eos" property for input pads
When set, it causes videoaggregator to repeatedly aggregate the last buffer on
an EOS pad instead of skipping it and outputting silence. This is useful, for
instance, while playing back files seamless one after the other, to avoid
videoaggregator ever outputting silence (the checkerboard pattern).

It is to be noted that if all the pads on videoaggregator have this property set
on them, the mixer will never forward EOS downstream for obvious reasons. Hence,
at least one pad with 'ignore-eos' set to FALSE must send EOS to the mixer
before it will be forwarded downstream.

we think that 0 upstream latency is possible.

4b1bf9b52a videoaggregator: push the caps event as soon as we receive it

::negotiated_caps().  Without the caps event being sent prior,
downstream elements will be unable to answer and will return
an error.

unref when we are done in all cases.
