ce1d4d9f21 videomixer: Use the best width/height/etc if downstream can handle that 
Before it was always using whatever downstream preferred, while
the code and documentation claimed something different.

deeef84d2c videomixer: fix double unlock in segment seek segment code path 
We only want to unlock if we push an event downstream and
jump to done_unlock label afterwards. We would also unlock
in case of a segment seek and then unlock again later, and
nothing good can come of that.

(This code looks a bit dodgy anyway though, shouldn't it
also bail out with FLOW_EOS here in case of a segment seek
scenario, just without the event?)

373eceef7c videomixer2: store video info with buffers to keep it in sync 
Instead the queued buffer might have an old caps while the pad
is already storing the information for a new caps. Mixing those
while handling buffers will often lead to issues

83f8ee1d41 videomixer2: Merge tag events to send them in collected. 
Otherwise there were race conditions where we would send tags
on a flushing srcpad.

We have a test for that in GES, but this should be tested
systematically with harness in the future as I believe it
is useful for exactly that kind of cases.

e47ffb203b videomixer: Do not send flush_stop ourself after a flush_start

6c349d6ec3 videomixer: Send EOS if buf_end >= segment.stop 
That means the whole segment is already played, and we are sure we
are EOS at that point.

Also handle segment seeks, and do not send EOS in that case.

d67a671bfb videomixer: use gst_util_uint64_scale*_round. 
There could be a case where:
      1) you do a new set_caps after buffers have been processed.
      2) ts_offset gets set to a different value, eg 0.033333333
      3) your pads get EOS, but the check dor that doesn't work
         because you use ts_offset + a truncated value < segment.stop
      4) so in the next collected, you end up comparing for example:
      0.9999999999 > 1., which is false and means you don't send EOS.

Also adds scale_round in two other places where it potentially could
have caused problems.

3d0988f46f videomixer: Fix handling of buffers without a duration 
We'll have to pop buffer from collectpads and store it
internally only to get the timestamp of the next buffer.
If we continue to keep it in collectpads, no new buffer
to calculate the end time will ever arrive.

When the segment start is not 0, this created a situation where

of the next buffer ended up underflowing.

718f9004d0 videomixer: Do not send flush_stop when receiving a seek 
There is no reason to send a flush-stop when receiving a seek event.
In the case of a flushing seek, we could eventually want to, but in
the code path were we check if the seek is "flushing", we have the
following comment that makes sense:

"we can't send FLUSH_STOP here since upstream could start pushing data
after we unlock mix->collect.
We set flush_stop_pending to TRUE instead and send FLUSH_STOP after
forwarding the seek upstream or from gst_videomixer_collected,
whichever happens first."

Actually this is not how it is supposed to work. videomixer
creates a [0,-1] segment and then puts frames of the different
streams there based on their running times in their own segments.
