Implement the sink event handling like the src event handler. Make the default
implementation parse and forward the event. This makes it possible to actually
return an error value from the event handler.
Remove the requirement to have to return a ref to the input buffer when in
passthrough mode. This saves a few ref/unref cycles and fixes another 0.11
FIXME.
Remove the caps and size from the prepare_output_buffer function. with
bufferpools and capsnego done differently, we don't need this in most cases and
if we do, we can simply use the transform_size function and get the caps from
the srcpad.
Improve GstSegment, rename some fields. The idea is to have the GstSegment
structure represent the timing structure of the buffers as they are generated by
the source or demuxer element.
gst_segment_set_seek() -> gst_segment_do_seek()
Rename the NEWSEGMENT event to SEGMENT.
Make parsing of the SEGMENT event into a GstSegment structure.
Pass a GstSegment structure when making a new SEGMENT event. This allows us to
pass the timing info directly to the next element. No accumulation is needed in
the receiving element, all the info is inside the element.
Remove gst_segment_set_newsegment(): This function as used to accumulate
segments received from upstream, which is now not needed anymore because the
segment event contains the complete timing information.
Make sure property names passed to g_object_notify() are in the canonical form
(ie. "last-message" not "last_message"), so that g_param_spec_pool_lookup()
doesn't have to do strdup/canonicalize/free for every single notify call.
This only applies when building against older GLib versions (< 2.26).
Use more efficient g_object_notify_by_pspec() if we're compiling against
GLib >= 2.26, and also remove work-around for g_object_notify() thread-
safety issues with older GLib versions if it's not needed any more.
There's not much point in using GST_DEBUG_FUNCPTR with GObject
virtual functions such as get_property, set_propery, finalize and
dispose, since they'll never be used by anyone anyway. Saves a
few bytes and possibly a tenth of a polar bear.
Out-of-band events might lead to us calling g_object_notify() from a
non-streaming thread, which can cause crashes if g_object_notify() is
being called from the streaming thread at the same time. See #554460.
Original commit message from CVS:
* plugins/elements/gstidentity.c:
Doc typo. Use return value of parent_class->event.
* plugins/elements/gsttypefindelement.c:
Chain up at the end for consistency.
Original commit message from CVS:
* plugins/elements/gstidentity.c: (gst_identity_event),
(gst_identity_start):
Fix imperfect timestamp/offset checks when we get another NEWSEGMENT
event after processing some data. Fixes bug #526042.

Patch by: Mark Nauwelaerts <manauw at skynet be>
* plugins/elements/gstidentity.c: (gst_identity_class_init),
(gst_identity_init), (gst_identity_prepare_output_buffer):
Identity is not always a passthrough element, it can modify the buffer
timestamps when it has a datarate and operates in single-segment mode.
We therefore make it an in_place filter with a custom buffer prepare
function that conditionally makes the input buffer metadata writable
when needed. Fixes#523985.
Original commit message from CVS:
* plugins/elements/gstidentity.c (gst_identity_check_imperfect_offset):
So we should use correct constants for checking for None offset.

Rename non-perfect to imperfect for Mike and for the sanctity of
the language.
Also make sure bus message gets emitted for data-incontiguities.

Drop-probability is broken, mention this in the code with a
FIXME and also in the property description.
Make silent also be silent about the drop messages.
