ae729440b1 videomixer: use GST_STIME_ARGS for GstClockTimeDiff
No need to manually handle negative values of diff, GST_STIME_ARGS does
exactly this.

c1a96113db videomixer: Revert the last commit and handle resolutions differences properly
This is about converting the format, not about converting any widths and
heights. Subclasses are expected to handler different resolutions themselves,
like the videomixers already do properly.

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.

4243714301 videomixer: add mix->segment.start to output_end_time
When the segment start is not 0, this created a situation where
the output_end_time is inferior to output_start_time, and the duration
of the next buffer ended up underflowing.
