12d2d01663 pad: Check sinkpad for flushing
Check the sinkpad for the flushing state before calling the chainfunction on the
pad. We do this by checking the cache (which is also cleared on the srcpad when
the sink is set to flushing).

Fixes #641928

59bc71c47a pad: don't cache the peer chainfunc
There is no need to cache the peer chainfunction as we can just as efficiently
get to it from the peer object. Also not caching the chain function works better
because then we automatically get the new chainfunctions when they change.

b83e66be46 pad: improve pad push caching
Build the cache while we push data. When we don't have a cache, we run the
slowpath and collect cacheable properties. When all conditions are met, keep the
cached data around so that we can more efficiently push data around.

f2f7842f6b pad: Set the event source object if none is set yet in gst_pad_push_event()
Otherwise the source will stay at NULL, the event is passed to the
peerpad via gst_pad_send_event() and then the peerpad is set as
source of the event instead of the originating pad.

fd6334cb7c pads: use new g_object_notify_by_pspec() for caps notifies if available
If we're building against GLib >= 2.26.0, we can use the more efficient
g_object_notify_by_caps(), which avoids the param spec lookup.

60fba4df8b gstpad: Fix flush-stop event handling
A flush-stop event would make a pad unflushing, causing it
to start acting as an activated pad. This, for example,
could lead to the chain function being called when stuff
isn't initialized.

This could happend when setting qtdemux to NULL while a seek
was being handled in the upstream filesrc (in push mode).

This patch makes it check if it is activated before setting
it to unflushing.

21c8edca2a gstpad: Assume pads are compatible if we don't have templates
This is the same behaviour as if we had a pad template caps of
GST_CAPS_ANY on any of the pads (i.e. the actual check will be done
during caps negotiation).

7fa58dbebd GstPad: Do not call gst_pad_accept_caps() when caps change
Instead just check that the caps intersect with the pad template.
The elements should properly accept/refuse the caps in setcaps().

Shaves off calling the default implementation of acceptcaps which does
an expensive gst_pad_get_caps() (so if you have 50 of those elements in
a row, you'd be doing factorial(50) gst_pad_get_caps...).

Does not break any module unit test and most apps work fine.

defined.

this, to avoid frustration. See countless bug reports in bugzilla.

We need to check the pad caps on the srcpad as well as on the sinkpad. Revert
this commit as it removes the check on the srcpad and can leave the srcpad
unnegotiated (or negotiated with wrong caps)
