02d88fc3f3 pad: check template caps for proxy pads in accept-caps
Validate that the proxy pad indeed accepts the caps by also
comparing with the pad template caps, otherwise when the pad
had no internally linked pads it would always return true.

ca22e60b91 pad: Mark sticky events as sent on not-linked
Instead of re-sending sticky events over and over to a not-linked
pad, mark them as sent the first time. If the not-linked came from
downstream, it already received the events. If the pad is actually
not-linked, the sticky events will be rescheduled when the
pad is linked anyway.

41e1bea7ef buffer: Add a GST_BUFFER_DTS_OR_PTS macro

45f0f354ac segment: Correct stream_time calc for negative applied rate
Updated gst_segment_position_from_stream_time and gst_segment_to_stream_time to reflect correct calculations for the case when the applied rate is negative.

Pasting from design docs:

===============================
Stream time is calculated using the buffer times and the preceding SEGMENT
event as follows:

    stream_time = (B.timestamp - S.start) * ABS (S.applied_rate) + S.time

For negative rates, B.timestamp will go backwards from S.stop to S.start,
making the stream time go backwards.
===============================

Therefore, the calculation for applied_rate < 0 should be:

    stream_time = (S.stop - B.timestamp) * ABS (S.applied_rate) + S.time

and the reverse:

    B.timestamp = S.stop - (stream_time - S.time) / ABS (S.applied_rate)

d5ded15889 bin: implement context propagation when adding elements
When adding an element to a bin we need to propagate the GstContext's
to/from the element.

This moves the GstContext list from GstBin to GstElement and adds
convenience functions to get the currently set list of GstContext's.

This does not deal with the collection of GstContext's propagated
using GST_CONTEXT_QUERY.  Element subclasses are advised to call
gst_element_set_context if they need to propagate GstContext's
received from the context query.

When a running-time-offset is stored in the event, it could become smaller

7f0e0ff3ca gstpad: Add a new GST_PROBE_HANDLED return value for probes
In some cases, probes might want to handle the buffer/event/query
themselves and stop the data from travelling further downstream.

While this was somewhat possible with buffer/events and using
GST_PROBE_DROP, it was not applicable to queries, and would result
in the query failing.

With this new GST_PROBE_HANDLED value, the buffer/event/query will
be considered as successfully handled, will not be pushed further
and the appropriate return value (TRUE or GST_FLOW_OK) will be returned

This also allows probes to return a non-default GstFlowReturn when dealing
with buffer push. This can be done by setting the
GST_PAD_PROBE_INFO_FLOW_RETURN() field accordingly

794a08d7e9 pad: fix invalid unref after IDLE probe on non-OK flow return
In case there is an IDLE probe fired from gst_pad_push_data and it
doesn't return GST_FLOW_OK, the code jumps to the probe_stopped
label which tries to unref the data object. However, at this point
the data object belongs downstream and must not be touched.
By setting data = NULL, the code skips this unref.

A core meta which helps implement the old concept
of sub-buffering in some situations, by making it
possible for a buffer to keep a ref on a different
parent buffer. The parent buffer is unreffed when
the Meta is freed.

This meta is used to ensure that a buffer whose
memory is being shared to a child buffer isn't freed
and returned to a buffer pool until the memory
is.

7130230ddb memory: provide a mem_unmap function that takes the flags to unmap
There are gstmemory's available that operate in two memory domains
and need to ensure consistent access between these domains.

Imagine a scenario where e.g. the GLMemory is mapped twice in both
the GPU and the CPU domain.  On unmap or a subsequent map, it would
like to ensure that the most recent data is available in the memory
domain requested.  Either by flushing the writes and/or initiating a
DMA transfer.  Without knowing which domain is being unmapped, the
memory does not know where the most recent data is to transfer to
the other memory domain.

Note: this still does not allow downgrading a memory map.

f9e5178dd1 gstvalue: Add GstFlagSet type
GstFlagSet is a new type designed for negotiating sets
of boolean capabilities flags, consisting of a 32-bit
flags bitfield and 32-bit mask field. The mask field
indicates which of the flags bits an element needs to have
as specific values, and which it doesn't care about.

This allows efficient negotiation of arrays of boolean
capabilities.

The standard serialisation format is FLAGS:MASK, with
flags and mask fields expressed in hexadecimal, however
GstFlagSet has a gst_register_flagset() function, which
associates a new GstFlagSet derived type with an existing
GFlags gtype. When serializing a GstFlagSet with an
associated set of GFlags, it also serializes a human-readable
form of the flags for easier debugging.

It is possible to parse a GFlags style serialisation of a
flagset, without the hex portion on the front. ie,
+flag1/flag2/flag3+flag4, to indicate that
flag1 & flag4 must be set, and flag2/flag3 must be unset,
and any other flags are don't-care.

abdafb0d64 protection: add GstProtectionMeta to support protected content
In order to support some types of protected streams (such as those
protected using DASH Common Encryption) some per-buffer information
needs to be passed between elements.

This commit adds a GstMeta type called GstProtectionMeta that allows
protection specific information to be added to a GstBuffer. An example
of its usage is qtdemux providing information to each output sample
that enables a downstream element to decrypt it.

This commit adds a utility function to select a supported protection
system from the installed Decryption elements found in the registry.
The gst_protection_select_system function that takes an array of
identifiers and searches the registry for a element of klass Decryptor that
supports one or more of the supplied identifiers. If multiple elements
are found, the one with the highest rank is selected.

This commit adds a unit test for the gst_protection_select_system
function that adds a fake Decryptor element to the registry and then

0f36b16a29 event: add new GST_EVENT_PROTECTION
In order for a decrypter element to decrypt media protected using a
specific protection system, it first needs all the protection system
specific  information necessary (E.g. information on how to acquire
the decryption keys) for that stream.

The GST_EVENT_PROTECTION defined in this commit enables this information
to be passed from elements that extract it (e.g. qtdemux, dashdemux) to
elements that use it (E.g. a decrypter element).

3d8de8a4f9 pad: block data flow when idle probe is running
When idle probe runs directly from the gst_pad_add_probe() function
we need to make sure that no data flow happens as idle probe
is a blocking probe. The idle probe will prevent that any
buffer, bufferlist or serialized events and queries are not
flowing while it is running.

a3b42ec42a bin: undo upward state changes on children when a child fails
When a bin changes states upwards, and a child fails to change,
any child that was already switched will not be reset to its
original state, leaving its state inconsistent with the bin,
which does not change state due to the failure.

If the state change was from NULL to READY, it means that deleting
this bin will cause those children to be deleted while not in
NULL state, which is a Bad Thing. For other upward changes, it
is less of a problem, as a subsequent switch back to NULL will
cause an actual downwards change on those inconsistent elements,
albeit from the "wrong" state.

We now reset state to the original one when a child fails.

Includes unit test.

b8f5a7ba45 elementfactory: add DECRYPTOR class defines
An element that performs decryption does not naturally fit within any
of the existing element factory class types. It is useful to be able
to easily get a list of all elements that support decryption so that
a union can be computed between the protection systems that have a
supported decryptor and the allowed protection systems for a particular
stream.

This commit adds a new GST_ELEMENT_FACTORY_TYPE_DECRYPTOR and its
associated string identifier "Decryptor". It also adds
GST_ELEMENT_FACTORY_TYPE_DECRYPTOR to GST_ELEMENT_FACTORY_TYPE_DECODABLE
so that uridecodebin can auto-plug a decryption element.

5deb4f658e pad: allow probes to remove the data item whilst returning PROBE_OK
Use case: we want to block the source pad of a leaky queue and
drop the buffer that causes the block. If we return PROBE_DROP
then the buffer gets dropped, but we get called again. If we
return PROBE_OK we can't easily drop the buffer. If we just
replace the item into the GstPadProbeInfo structure with NULL,
GStreamer will push a NULL buffer to the next element when we
unblock the pad probe. This patch ensures it doesn't do that.

f9baff11c8 Revert "element: set pads need-parent flag to false when removing"
This reverts commit 1911554cff.

This breaks the functionality of GST_PAD_FLAG_NEED_PARENT, the reason for this
flag is that if a pad is removed from a running element, you don't want
functions (such as chain or event) to be called on the pad without a parent set.
This can happen if you remove a request or sometimes pad from a running element.

I don't see the code that caused this in tsdemux, but if it needs to unset
the flag on remove, it should do it itself and then make sure that the parent
exists in any pad function.

da7847d1ad message, bus: fix async message delivery
Async message delivery (where the posting thread gets blocked
until the message has been processed and/or freed) was pretty
much completely broken.

For one, don't use GMutex implementation details to check
whether a mutex has been initialized or not, esp. not
implementation details that don't hold true any more with
newer GLib versions where atomic ops and futexes are used
(spotted by Josep Torras). This led to async message
delivery no longer blocking with newer GLib versions on
Linux.

Secondly, after async delivery don't free mutex/GCond
embedded inside the just-freed message structure.

Use a new (private) mini object flag to signal GstMessage
that the message being freed is part of an async delivery
on the bus so that the dispose handler can keep the message
alive and the bus can free it once it's done cleaning up
stuff.

Add GST_SEEK_FLAG_TRICKMODE_KEY_UNITS and

Do the same for the corresponding SEGMENT flags.
