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.

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."

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.

13328bc129 videomixer2: Fix race condition where a src setcaps is ignored
If both pads receive data at the same time, they will both get their
sink_setcaps called which will call the src_setcaps, but there is
a race condition where the second one might not be called.

f5e0321dfc videomixer: clear video frame more correctly
Make sure not to touch memory that doesn't belong to
our frame, we might be one part of a side-by-side 3D
frame, or in a picture-in-picture scenario.

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.

Add private replacements for deprecated functions such as

to avoid the deprecation warnings. We'll change these
over to the new API once we depend on glib >= 2.32.

69b5aedc58 videomixer2: Add transparent background option for alpha channel formats
This option allows the videomixer2 element to output a valid alpha
channel when the inputs contain a valid alpha channel. This allows
mixing to occur in multiple stages serially.

The following pipeline shows an example of such a pipeline:

gst-launch videotestsrc background-color=0x000000 pattern=ball ! video/x-raw-yuv,format=\(fourcc\)AYUV ! videomixer2 background=transparent name=mix1 ! videomixer2 name=mix2 ! ffmpegcolorspace ! autovideosink  videotestsrc ! video/x-raw-yuv,format=\(fourcc\)AYUV ! mix2.

The first videotestsrc in this pipeline creates a moving ball on a
transparent background. It is then passed to the first videomixer2.
Previously, this videomixer2 would have forced the alpha channel to
1.0 and given a background of checker, black, or white to the
stream. With this patch, however, you can now specify the background
as transparent, and the alpha channel of the input will be
preserved. This allows for further mixing downstream, as is shown in
the above pipeline where the a second videomixer2 is used to mix in a
background of an smpte videotestsrc. So the result is a ball hovering
over the smpte test source. This could, of course, have been
accomplished with a single mixer element, but staged mixing is useful
when it is not convenient to mix all video at once (e.g. a pipeline
where a foreground and background bin exist and are mixed at the final
output, but the foreground bin needs an internal mixer to create
transitions between clips).

Fixes bug #639994.
