f4ad5f0cdf aggregator: don't use iterator when setting flush pending on pads 2017-12-02 15:10:26 +00:00

0db6fc999b aggregator: check if pads are ready more efficiently
No need to use an iterator for this which creates a temporary
structure every time and also involves taking and releasing the
object lock many times in the course of iterating. Not to mention
all that GList handling in gst_aggregator_iterate_sinkpads().

c5e3fe807a aggregator: move property member into private structure
Our locking (or lack thereof) while accessing this also

601554df70 aggregator: bring start/stop vfunc semantics in line with other baseclasses
Sub-class should not have to chain up to GstAggregator's start/stop
vfuncs, same as in GstBaseSrc, GstBaseSink, GstBaseTransform etc.

4846f06b41 aggregator: Wait for the minimum latency, not the maximum
The minimum latency is the latency we have to wait at least
to guarantee that all upstreams have produced data. The maximum
latency has no meaning like that and shouldn't be used for waiting.

bbde713640 aggregator: Take the stream lock when iterating sink pads
When iterating sink pads to collect some data, we should take the stream lock so
we don't get stale data and possibly deadlock because of that. This fixes
a definitive deadlock in _wait_and_check() that manifests with high max
latencies in a live pipeline, and fixes other possible race conditions.

7240852e55 aggregator: Wake up the src thread after handling a latency query
Due to changed latencies or changed live-ness we might have to
adjust if we wait on a deadline at all and how long.

a20863a7ec aggregator: Don't count the number of times we need to wake up but instead check all conditions for waiting again
This simplifies the code and also makes sure that we don't forget to check all
conditions for waiting.

Also fix a potential deadlock caused by not checking if we're actually still
running before starting to wait.

b1dcc7efb0 aggregator: Add function to allow subclasses to set their own latency

be the duration of one output frame.

435a477f63 aggregator: Add a timeout parameter to ::aggregate()
When this is TRUE, we really have to produce output. This happens
in live mixing mode when we have to output something for the current
time, no matter if we have enough input or not.

f4b86a6d8c aggregator: make the src pad task drive the pipeline for live pipelines
This removes the uses of GAsyncQueue and replaces it with explicit
GMutex, GCond and wakeup count which is used for the non-live case.

For live pipelines, the aggregator waits on the clock until either
data arrives on all sink pads or the expected output buffer time
arrives plus the timeout/latency at which time, the subclass
produces a buffer.

0ad159dfb4 aggregator: Block serialized events/queries until the pad has consumed all buffers
Otherwise the caps of the pad might change while the subclass still works with
a buffer of the old caps, assuming the the current pad caps apply to that
buffer. Which then leads to crashes and other nice effects.

376de6cef3 audiomixer: critical error for blocksize, timeout min/max values
Audiomixer blocksize, cant be 0, hence adjusting the minimum value to 1
timeout value of aggregator is defined with MAX of MAXINT64,
but it cannot cross G_MAXLONG * GST_SECOND - 1
Hence changed the max value of the same

efdcc6c8eb aggregator: add a timeout property determining buffer wait time
Determines the amount of time that a pad will wait for a buffer before
being marked unresponsive.

Network sources may fail to produce buffers for an extended period of time,
currently causing the pipeline to stall possibly indefinitely, waiting for
these buffers to appear.

Subclasses should render unresponsive pads with either silence (audio), the
last (video) frame or what makes the most sense in the given context.

e8c34afd5f aggregator: Replace GMainContext with GAsyncQueue (v2)
The previous implementation kept accumulating GSources,
slowing down the iteration and leaking memory.

Instead of trying to fix the main context flushing, replace
it with a GAsyncQueue which is simple to flush and has
less overhead.

1efd6b2edd aggregator: Add a streaming lock so to secure flush start action
Without a lock that is taken in FLUSH_START we had a rare race where we
end up aggregating a buffer that was before the whole FLUSH_START/STOP
dance. That could lead to very wrong behaviour in subclasses.
