5da08a21c6 splitmuxsink: Don't leak old muxer/sink in async mode
Make sure to clear the reference taken earlier in the function
when switching muxer/sink asynchronously so they don't leak

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.

f667ab05d2 Revert "splitmuxsrc: Make sure events are writable"
This reverts commit 3ac5430311.

There's no need to make a freshly created event writable,
and the other half of this patch was already fixed
and pushed in f2f15a1

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.

42f5f3d1be splitmuxsink: Allow splitting at exactly the time/bytes threshold
76e458a119 changed the conditions from
"queued > threshold" to "queued >= threshold", which broke hlssink2 and

be at *exactly* the configured threshold.

ad8a6cb639 qtmux: send stream warning when refusing video caps

ddd4fe680f splitmuxsrc: properly set total duration on outgoing segment
We would accidentally pass through the duration value from the
demuxer from a single fragment, which causes problems when
feeding the stream from splitmuxsrc to rtsp-server. Streaming
would stop after one fragment due to that.

dccfaf2e91 multifilesrc: implement uri handler
With this patch we can now provide a set of files
created by multifilesink as a source for uri elements.

e.g. gst-launch-1.0 playbin uri=multifile://img%25d.ppm

Note that for the %d pattern you need to replace % with %25.
This is to be compliant with URL naming standards.

76e458a119 splitmuxsink: Use muxer reserved space properties if present.
If the use-robust-muxing property is set, check if the
assigned muxer has reserved-max-duration and
reserved-duration-remaining properties, and if so set
the configured maximum duration to the reserved-max-duration
property, and monitor the remaining space to start
a new file if the reserved header space is about to run out -
even though it never ought to.

internal sources like qtdemux might throw an error

happen is either flushing or shutdown, and those
will be handled anyway.

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.

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.
