This prevents adding duplicates over and over again to the resulting
caps if they already describe the new intersection result.
While this changes intersection from O(n*m) to O(n^2*m), it results in
smaller caps, which in the end will decrease further processing times.
For example in an audioconvert ! audioconvert ! audioconvert pipeline,
when forwarding the downstream caps preference in basetransform
(see e26da72de25a91c3eaad9f7c8b2f53ba888a0394) this results in
16 instead of 191 caps structures.

This reverts commit 9ef1346b1f.
Way to much for one commit and I'm not sure we want to get rid of the pad caps
just like that. It's nice to have the buffer and its type in onw nice bundle
without having to drag the complete context with it.
Remove pad_alloc and all references. This can now be done more efficiently and
more flexible with the ALLOCATION query and the bufferpool objects. There is no
reverse negotiation yet but that will be done with an event later.
Currently fails (in normal circumstances) because we create a
socket pair for each bin's bus and exhaust the number of available
file descriptors.

Adding a buffer to the end of a GstBufferList is supposed to be a fast
operation, but it was not since the iterator does not advance its
nextpointer when adding buffers and GList does not have a tail pointer.
Using a GQueue to store the buffers makes it easier to add buffers to
the end of the list and this operation will now be much more efficient.
Adding an entire GList of buffers using
gst_buffer_list_iterator_add_list() will however have to iterate over
the list being added to be able to update the tail pointer in the
GQueue.
Replace subbuffer and copy vmethods by a more generic transform function that
can then be parametrised by transform specific data. This should allow us to
implement make-writable and more future transform functions.
Our helloworld example thatw e reference from the manual has been a bit
complicated to serve a first contact with gstreamer. Since we have and
promote playbin2 as a playback api use it here.

Fixes#424143
Make separate api for getting and adding metadata. This allows us to pass extra
parameters to the init functions when creating metadata, which is needed for
specific API implementations.
Add beginnings of memory metadata.
Add first implementation of arbitrary buffer metadata. We use a simple linked
linked of slice allocated metadata chunks. Future implementations could use
something more performant.
Add get, remove, iterate methods to handle the metadata.
Passing e.g. location=foo would lead to warnings because g_filename_to_uri()
wants an absolute file path and returns NULL otherwise. Use brand-new
gst_filename_to_uri() instead, which will try harder to create a proper
URI for us.
Also add unit test.
Avoid doing unnecessary pad-allocs when on passthrough mode.
If multiple basetransform elements are on a pipeline, they
would do a pad-alloc for each received buffer, each element
would do this, so we would have lots of pad allocs on the
pipeline for a single buffer being pushed through it.
This patch attempts to reduce this amount by avoiding
doing pad-allocs if the element has already done it
after the last pushed buffer. So it will only be allowed
to do a new pad-alloc after it has pushed a buffer, so we get
1x1 pad-alloc and buffer ratio

Makes gst_bus_add_watch(), gst_bus_add_watch_full(), gst_bus_add_signal_watch(),
and gst_bus_add_signal_watch_full() convenience functions automatically pick up
any non-default main contexts set for the current thread via
g_main_thread_push_thread_default().
Remove code that isn't needed any longer, which sets the multiqueue
to PLAYING and back before unreffing, in order to avoid a deadlock
waiting for gstpad tasks that were never started. The problem seems
to have been fixed long ago.
The unit tests are riddled with g_assert() and friends, make sure we
don't disable assert and cast checks for the unit tests even if
this has been specified for the rest of the code base, e.g. via
--disable-glib-asserts.
Adds getcaps/setcaps to output-selector and adds a property
to select which type of negotiation should be done.
The available modes are:
* none: no negotiation (current behavior), getcaps return ANY and
setcaps aren't set on any of the peers
* all: use all pads (default), getcaps returns the intersection of
peer pads and setcaps is set on all peers
* active: getcaps and setcaps are proxied to the active pad

Make the _get_caps functions behave like the _get_caps_reffed variants and
remove the _reffed variants. This means that _get_caps doesn't return a writable
caps anymore and an explicit _make_writable() is needed before modifying the
caps.
Fix returning of timezones on systems with gdatetime
to use floats on the math expression to avoid
truncating the fractional part.
Also adds a test for covering this case.
Unify the different position reporting code paths to make it more
understandable.
Use start_time to get more accurate position reporting in paused.
Fix unit tests for more accurate reporting.

Only try to build (pseudo-)C++ unit test if a working C++ compiler has been
found, otherwise the build will fail. (We do this to make sure our headers
are 'C++ clean').
Add a function to retrieve a list of buffers containing the first N bytes from
the adapter. This can be done without a memcpy and should make it possible to
transfer the list to a GstBufferList later.
Added a new query type to retrieve informations about the areas of the
media currently buffered. See bug 623121.

Catch errors and warnings on the bus. This fixes hanging pipelines in the case
of bugs elsewhere. Also print state-change messages to give more detail on the progress.
When basetransform received an unsupported caps on pad_alloc
it just returned not-negotiated. This patch makes it query
the allowed caps between his sinkpad and upstream's srcpad
to find a caps to suggest.
This happens when dinamically switching pipeline elements
and upstream pad_allocs with the previous caps that was
being used.

This is a string describing a date and/or date/time in a simple subset of
the ISO-8601 format, namely either "YYYY-MM-DD" or "YYYY-MM-DDTHH:MMZ" (with
'T' the date/time separator and the 'Z' indicating UTC).
The main purpose of this field is to keep track of plugin and element versions
on an absolute timeline, so it's possible to determine which one is newer when
comparing two date time numbers. This will allow us to express 'replaces'-type
relationships betweeen plugins and element factories in future, even across
different modules and plugin merges or splits (source module version numbers
aren't particularly useful here, since they can only meaningfully be compared
within the same module). It also allows applications and libraries to reliably
check that a plugin is recent enough without making assumptions about modules
or module versions.
We use a string here to keep things simple and clear, esp. on the build system
side of things.

Add a new enable-last-buffer property. When false, it disables storing the last
received buffer in basesink::last-buffer. This can be useful in cases where
buffers need to be released asap.

Pipeline serialisation to and from XML is horribly broken for all
but the most simple use cases, and will likely never be fixed.
Make sure everyone playing around with these tools is aware of
this, to avoid frustration. See countless bug reports in bugzilla.
