Thibault Saunier 9f4a8ccdf4 videomixer: Do not check if caps are empty when they are NULL
In the case the caps are actually NULL, we should just concider it the
same way as empty caps in that case.

Mathieu Duponchelle 707e39fe7a videomixer: Don't send reconfigure event when formats or PAR are different

Mathieu Duponchelle 5d21f8f2e3 videomixer: don't send flush_stop twice.
If we get flush start and a seek we need to only send flush_stop once.

Thibault Saunier e47ffb203b videomixer: Do not send flush_stop ourself after a flush_start
When we receive a flush_start, we should wait for the next flush_stop
and foward it, not create a flush_stop ourself.

Thibault Saunier 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.

Thibault Saunier c5fa4666b7 videomixer: Make sure to send EOS if the buffer end time equals the segment end time
Otherwize EOS never gets sent in that particular case.

Mathieu Duponchelle 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.

Sebastian Dröge 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.

This reverts commit 2d3910fc79.

Mathieu Duponchelle 6e23f1fec4 videomixer: check last end_time after conversion to running segment
The last end_time was saved after conversion, so the comparison
had to be made after conversion for it to make sense.

Mathieu Duponchelle 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.

Thibault Saunier 608bd3e2db videomixer: Do not take COLLECT_PADS_STREAM_LOCK when unnecessary

Thibault Saunier 86b106091c videomixer: Send caps event from the streaming thread
This way we avoid races in caps negotiation and we make sure
that the caps are sent after stream-start.

Thibault Saunier 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."

Sebastian Dröge 3110b7cc31 Revert "videomixer2: Take into account new segments"
This reverts commit 84ae670ab4.

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.

Douglas Bagnall 0b898ab911 videoconvert: Compare y offset with height, not width, when testing for overlap
This could have prevented images showing that should have when the
source height is greater than its width.

When width exceeds height, as is common, it probably only caused a
miniscule amount of unnecessary work.  I haven't tested.

Tim-Philipp Müller 626e0258e3 videomixer: fix warnings when using transparent background
gst_video_frame_map() increases the refcount, which makes
the buffer not writable any more technically, so calling
gst_buffer_memset() on it will cause nasty warnings.

Unit test disabled because it very rarely (for me)
fails, possibly negotiation-related.
