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.
This leads to memory corruption

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.

d4c4af699e aggregator: Add a timeout parameter to ::aggregate()

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.

75b0bac7f8 adaptivedemux: fix seek event handling
Properly do seeking and avoid only seeking when the segment was updated.
It would cause seeks after the stream was EOS to fail, for example.

a7712c2983 adaptivedemux: use gst_task_stop instead of gst_task_pause
To avoid race conditions with gst_task_stop(); gst_task_join() with
another thread doing gst_task_pause(), the joining thread would be
waiting for the task to stop but it would never happen. So just
use gst_task_stop() everywhere to prevent more mutexes

023b284c2d adaptivedemux: also clear flushing state on pads before restarting
During flushing seeks the flushing flow return will propagate up to the
source element and all pads are going to have the flushing flag set.

So before restarting also remove that flag together with the EOS one.

We don't do that when pushing the flush stop event because our event
handler for the proxypad will drop all events.
