fbd4cf9810 aggregator: don't use iterator when setting flush pending on pads 2015-01-04 17:25:45 +00:00

4da01dadcc 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().

6e30a98fd5 aggregator: move property member into private structure 
Our locking (or lack thereof) while accessing this also
looks generally quite dodgy.

b4d2deb6d6 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.

6449e3d897 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.

f3efb9e7d6 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.

c65aeedb6f adaptivedemux: check if element exists before setting it to null 
Under certain error conditions it might happen that the element
has been freed already and trying to set it to NULL causes an
assertion

3dfab51b92 adaptivedemux: make sure task has stopped before freeing it 
Otherwise the thread will be running and its memory will get freed.

0bef1974e2 adaptivedemux: fix segment start when exposing new streams 
Segment start needs only to be updated when starting the streams
or after a seek, doing it during bitrate changes will cause the
running time to go discontinuous (jump back to a previous ts)
and QOS will drop buffers

a27ff89d42 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.

341e5291c3 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.

207308446b glbufferpool: Always recalculate buffer size 
Actually we should always recalculate buffer size since our buffer size
even when not-padded is smaller for many sub-sampled formats. This is
because we don't add padding between the planes.

da3ae06cd1 glmemory: Handle upload/download flags from map 
Problem was that if buffer was mapped READWRITE (state of buffers from
libav right now), mapping it READ/GL will not upload. This is because the
flag is only set when the buffer is unmapped. We can fix this by setting
the flags in map. This result in already mapped buffer that get mapped
to be read in GL will be uploaded. The problem is that if the write
mapper makes modification afterward, the modification will never get
uploaded.

06a4e80be9 aggregator: Add function to allow subclasses to set their own latency

be the duration of one output frame.

d4c4af699e 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.

8bf53a1226 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.

the newest buffer is always used for rendering
