335c9f28d6 splitmux: Rewrite buffer collection and scheduling
Majorly change the way that splitmuxsink collects
incoming data and sends it to the output, so that it
makes all decisions about when / where to split files
on the input side.

Use separate queues for each stream, so they can be
grown individually and kept as small as possible.

This removes raciness I observed where sometimes
some data would end up put in a different output file
over multiple runs with the same input.

Also fixes hangs with input queues getting full
and causing muxing to stall out.

f7009eb5d7 splitmuxsink: Add format-location-full signal
Add a new signal for formatting the filename, which receives
a GstSample containing the first buffer from the reference
stream that will be muxed into that file.

Useful for creating filenames that are based on the
running time or other attributes of the buffer.

To make it work, opening of files and setting filenames is
now deferred until there is some data to write to it,
which also requires some changes to how async state changes
and gap events are handled.

6a16f8ef2e splitmux: Fix a small race in the splitmuxsrc
Make sure the state of the parser is set to

never commence.

eb5ee5b7a3 multifilesink: refactor max_files handling a bit
Use GQueue instead of a GSList so we don't have to traverse
the whole list to append something every time. And it also
keeps track of the number of items in it for us.

Add a function to add filenames to the list of old files and
use it in more places, so that memory doesn't build up in
other modes either if no max_files limit is specified.

a10c1cc060 multifilesink: don't leak memory when no max-files limit is set
Technically we weren't leaking the memory, just storing it internally
and never using it until the element is freed. But we'd still use more
and more memory over time, so this is not good over longer periods
of time. Only keep track of files if there's actually a limit set,
so that we will prune the list from time to time.

11fd0e6120 splitmuxsink: pad request fails for flvmux
splitmuxsink requests pad from element using pad template like "video_%u", "audio_%u" and "sink_%d". This is true for most of the muxers.
But splitmuxsink not able to request pad to flvmux as flvmux has "audio" and "video" as pad templates.
fix: splitmuxsink should fallback to "audio" and  "video" when template not found.

Commit 83e718 added a pad template to splitmux request

023998dd76 Revert "multifilesink: streamline the file-switch code a bit"
This reverts commit f1ceaab02f.

This broke atomic file writes in "buffer" mode. It did make
sure that any streamheaders are prepended to each file in
buffer mode as well, but that's not really needed in practice,
whereas atomic file writes are, so let's restore the status
quo ante for now since this was primarily a code cleanup anyway,
and if anyone needs to streamheaders in buffer mode too they
can make a patch to implement that differently. Re-implementing
the atomic writes in the element also seems way too much work.

fb835c100a splitmuxsink: Fix occasional deadlock when ending file with subtitle
Deadlock occurs when splitting files if one stream received no buffer during
the first GOP of the next file. That can happen in that scenario for example:
 1) The first GOP of video is collected, it has a duration of 10s.
    max_in_running_time is set to 10s.
 2) Other streams catchup and we receive the first subtitle buffer at ts=0 and
    has a duration of 1min.
 3) We receive the 2nd subtitle buffer with a ts=1min. in_running_time is set to
    1min. That buffer is blocked in handle_mq_input() because
    max_in_running_time is still 10s.
 4) Since all in_running_time are now > 10s, max_out_running_time is now set to
    10s. That first GOP gets recorded into the file. The muxer pop buffers out
    of the mq, when it tries to pop a 2nd subtitle buffer it blocks because the
    GstDataQueue is empty.
 5) A 2nd GOP of video is collected and has a duration of 10s as well.
    max_in_running_time is now 20s. Since subtitle's in_running_time is already
    1min, that GOP is already complete.
 6) But let's say we overran the max file size, we thus set state to
    SPLITMUX_STATE_ENDING_FILE now. As soon as a buffer with ts > 10s (end of
    previous GOP) arrives in handle_mq_output(), EOS event is sent downstream
    instead. But since the subtitle queue is empty, that's never going to
    happen. Pipeline is now deadlocked.

To fix this situation we have to:
 - Send a dummy event through the queue to wakeup output thread.
 - Update out_running_time to at least max_out_running_time so it sends EOS.
 - Respect time order, so we set out_running_tim=max_in_running_time because
   that's bigger than previous buffer and smaller than next.

20754db26f splitmuxsink: initialize mux_start_time properly
mux_start_time refers to the running_time of the buffer
that goes first in the output file. Normally this time is
0, so this variable is initialized to 0 during the state
change to PAUSED.

However, when dealing with dynamic pipelines and starting
a recording while the pipeline has already run for a while,
the running_time of the first buffer is > 0 and this causes
a problem with detecting the end of the first file(s) when
splitting by duration, because the code will later compare
the threshold_time with (last buffer running_time - mux_start_time)
and will get it wrong until mux_start_time advances enough
to make this difference < threshold_time, creating empty files
in the meantime.

a930a1364a splitmuxsink: prevent deadlock when states change too fast

the check_completed_gop loop and deadlocking the other threads
waiting for it to advance.

af6a09ae4c splitmuxsrc: make sure to push sticky events before adding pad
It allows the caps to be set on the pad before being added for
dynamic autoplugging to work.

600bab0056 splitmuxsrc: Fix startup and shutdown races.
Fix 2 startup races when things happen too quickly, and 1
at shutdown by holding a ref to the pads in use until the
loop functions exit.

Handle errors activating file parts and publish them on
the bus.

d61e5393f1 splitmuxsink: Mask async-start/done while switching files.
Sometimes, extra async-start/done from the internal sink
while the element is still starting up can cause splitmuxsink
to stall in PAUSED state when it has been set to PLAYING
by the app. Drop the child's async-start/done messages while
switching, so they don't cause state changes at the
splitmuxsink level.

3f39d06338 splitmuxsink: Take released-but-not-yet-output bytes into account
When deciding whether it's time to switch to a new file, take into
account data that's been released for pushing, but hasn't yet
been pushed - because downstream is slow or the threads haven't been
scheduled.

Fixes a race in the unit test and probably in practice - sometimes
failing to switch when it should for an extra GOP or two.

Also fix a problem in splitmuxsrc where playback sometimes
stalls at startup if types are found too quickly.

27c91bc881 multifilesink: Add a new max-duration file switching mode
This new mode ensures that files will never exceed a certain duration
based on incoming buffer PTS (and duration if present)

Note:
* You need timestamped buffers (duh). If some of the incoming buffers don't
  have PTS, then it will just accept them in the current file

db0abbd531 multifilesink: add "aggregate-gops" property to process GOPs as a whole
This property can be used in combination with next-file=max-size
(and perhaps a future next-file=max-duration) to make sure that
each file part starts cleanly with a key frame and the appropriate headers.

In order for this property to work correctly, upstream elements should make
sure than any headers that need to be written in a standalone file are:
1) in the streamheader caps field
2) and/or in the stream as one or more buffers marked with GST_BUFFER_FLAG_HEADER
   that are just before the keyframe buffer

This is useful for MPEG-TS/MPEG-PS file segmenting in
combination with mpegtsmux or mpegpsmux.

e00f0de4f3 multifilesink: post file message on EOS
When multifilesink is operating in any mode other than one file
per buffer, the last file created won't have a file message posted
as multifilesink doesn't handle the EOS event.

This patch fixes it by using the last position to post a file
message when EOS is received. This should ensure at least the
time related data and the filename are posted to the application
or other elements
