6fe214e7a9 splitmuxsink: Added a split-at-running-time action signal
The video file can now be split at an arbitrary time, given by the user
as an argument to the action signal.

9605028a71 splitmuxsink: Implement split-after
The behaviour of split-now is to output the current GOP after
starting a new file.

The newly-added split-after signal will output the current GOP
to the old file if possible once a new GOP is opened.

f8076e208b splitmuxsink: Fix reference counting loop
The stream context was holding a reference to the
internal queue and pads, with pad probes that were
in turn holding references to the stream context.

This lead to a leak if the request pads weren't explicitly
released.

f672116c72 splitmux: Improve handling of repeated timestamps
When handling input with timestamps that repeat, sometimes
splitmuxsink would get confused and ignore a keyframe.

The logic in question is a holdover from before the cmd queue
moved the file cutting to the multiqueue output side and made
it deterministic, so it's no longer needed on the input
here.

d11339d616 splitmuxsink: Added new async-finalize mode
This mode is useful for muxers that can take a long time to finalize a
file. Instead of blocking the whole upstream pipeline while the muxer is
doing its stuff, we can unlink it and spawn a new muxer+sink combination
to continue running normally.

This requires us to receive the muxer and sink (if needed) as factories,
optionally accompanied by their respective properties structures. Also
added the muxer-added and sink-added signals, in case custom code has to
be called for them.

0f1770f2bd splitmuxsink: Add new reset-muxer property
With this the muxer is not set to NULL after each segment but instead
only flush events are sent to it to reset the EOS state.

As a result, the muxer will keep stream state and e.g. mpegtsmux will
keep the packet continuity counter continuous between segments as needed
by hlssink2.

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.

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.

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
If the GOP is completed, pads have to start gathering for the
next one but it is possible that the the state might go to
COLLECTING_GOP_START and back to WAITING_GOP_COMPLETE before the
thread has a chance to wake up and proceed, leaving it trapped in
the check_completed_gop loop and deadlocking the other threads
waiting for it to advance.

To solve it, this patch also checks that tha input running time
hasn't changed to prevent this scenario.

1954726328 splitmuxsink: add probe on the multiqueue's sink pad instead of the ghost pad
because _release_pad tries to release it from ctx->sinkpad, which is
multiqueue's sink pad, and currently fails because the probe is not
installed there

b0ce43cde3 splitmuxsink: Protect property variables with the object lock.
Use the object lock instead of the splitmux lock to protect
internal property variables, so they're not locked when
switching to a new file.

for a condition that never happens.

0373fd8f65 splitmux: fix memory leak
If execution goes to the beach in line 981, buf_info goes out of scope without
the memory being free'd. Handle this case.

5e2214d309 splitmux: Implement new elements for splitting files at mux level.
Implement 2 new elements - splitmuxsink and splitmuxsrc.

splitmuxsink is a bin which wraps a muxer and takes 1 video stream,
plus audio/subtitle streams, and starts a new file
whenever necessary to avoid overrunning a threshold of either bytes
or time. New files are started at a keyframe, and corresponding audio
and subtitle streams are split at packet boundaries to match
video GOP timestamps.

splitmuxsrc is a corresponding source element which handles
the splitmux:// URL and plays back all component files,
reconstructing the original elementary streams as it goes.
