The problem lies in the fact that multiqueue will now operate somewhat
similarly to the flow aggregation logic of demuxers and therefore
will stopp whenever all downstream pads return NOT_LINKED and/or
UNEXPECTED and there's no more buffers to push.
The latest commits should not affect any regular use-case, but the bug
report will be kept open so the previous behaviour can be re-established
if needed.
Fixes#609486
When we receive an UNEXPECTED flowreturn from downstream, we must not shutdown
the pushing thread because upstream will at some point push an EOS that we still
need to push further downstream.
To achieve this, convert the UNEXPECTED return value to OK. Add a fixme so that
we implement the right logic to propagate the flowreturn upstream at some point.
Also clean up the unit test a little.
Fixes#608136
GObject may crash if two threads do concurrent g_object_notify() on the same
object. This may happen if fakesink receives an out-of-band event such as
FLUSH_START while processing a buffer or serialised event in the streaming
thread. Since this may happen with the default settings during a common
operation like a seek, and there seems to be little chance of a timely fix
in GObject (see #166020), we should hack around this issue by protecting all
of fakesink's direct g_object_notify() calls with a lock.
Also add unit test for the above.
Fixes#554460.
Fix a regression introduced by fix for #567725 in commit
1c7ab4ed4f. We should only call the preroll
function once namely when we did not yet commit the state change.
Add a unit test to check that we call the preroll function when interrupting the
clock_wait (see #567725).
Add a unit test to check that we only call the preroll function once.
Original commit message from CVS:
* plugins/elements/gsttee.c: (gst_tee_handle_buffer):
Fix flow aggregation of tee. Error out immediately for all flow returns
except OK and NOT_LINKED, return NOT_LINKED if all pads are not linked
and return OK if at least one pad is linked.
Before we errored out on "fatal" flow returns (i.e. not for WRONG_STATE)
and otherwise returned the flow return of the last pad, which is wrong.
* tests/check/elements/tee.c: (_fake_chain), (_fake_chain_error),
(GST_START_TEST), (tee_suite):
Add unit tests for the flow aggregation.

Original commit message from CVS:
* plugins/elements/gstqueue.c: (gst_queue_leak_downstream):
Since we're not called only from the chain function any longer,
we can't assume that there's always data in the queue, so move
the is_full check to the beginning of the loop (otherwise we'd
hit the assert when changing the limit properties while the
queue is empty or not running yet).
Also, only set a discont if items were actually removed from
the queue.

Test case for the above.

Make the declaration in the header for
gst_check_element_push_buffer_list match the implementation.
Fix up spelling, grammar and wording of the documentation in a few
places, and add the Since keyword to new API functions.
Use g_list_delete_link instead of g_list_remove in
gst_check_drop_buffers, since it's immeasurably more efficient.

* libs/gst/check/gstcheck.c:
* libs/gst/check/gstcheck.h:
Properly declare 'buffers', 'check_cond', 'check_mutex' extern

interposing to marry them all, which doesn't work on Solaris.

Make it so that pads are considered linked until a buffer is pushed
and discovered otherwise. This avoids problems with decodebin2 hanging
after a seek in the filesrc ! decodebin2 name=d ! fakesink d. ! fakesink
case.
Make sure we lock the multiqueue when updating the max-size properties.
Fix a crash on Solaris in a debug statement in get_request_pad that
passes a NULL string to GST_DEBUG.
* tests/check/elements/multiqueue.c: (mq_dummypad_chain),

of sequence while multiqueue discovers that they are not-linked.

Take the multiqueue lock when updating the fill level so we don't get
confused.
After applying a buffer or event on the src pad segment, make sure to
call gst_data_queue_limits_changed() to get the data queue to unblock
and check the filled state again.
Rework the not-linked pad handling so the logic is that not-linked
pads can push as fast as they like, but only so they never get
ahead of any linked pads.
