74dbbe0091 decodebin3: Always ensure we end up with parsebin or identity
This fixes a regression introduced by 6c4f52ea20

There are cases where the input stream will be push-based, time-segment and not
have a collection nor caps. This means the event-based checks are not sufficient
to decide when/where to plug in a identity or parsebin to process the input.

For those corner cases we setup a buffer probe to ensure we always end up with
at least a parsebin

Fixes #3609

81de6b7738 subparse: fix typefind with small srt files
The typefind code was rejecting content smaller than 128 bytes making it
impossible to play files with very small srt files.
But those can actually be properly detected so fix typefind to allow
smaller content and try its best with it.

6c4f52ea20 decodebin3: Avoid usage of parsebin even more
When dealing with push-based inputs, we are now delaying the creation of
parsebin/identity until we get all pre-buffer events.

We therefore can simplify the handling of new pads being linked and only have to
check if upstream can handle pull-based or not.

Avoids creating parsebin for parsed upstream data altogether

39f62862d8 decodebin3: Ensure we get a collection for parsed inputs
When we are dealing with parsed inputs (i.e. using identity), we need to ensure
that we have a valid stream collection (and therefore DBCollection) before
anything flows dowsntream.

In those cases, we hold onto those events until we get such a collection.

daa022b9ee decodebin3: New mechanism for handling collection and selections
This commit separates collection and selections into a new separate structure:
DecodebinCollection.

This provides a much cleaner/saner way of dealing with collections being
updated, gapless playback, etc...

There is now a list of DecodebinCollection in flight, of which two are special:
* input_collection, the currently inputted/merged collection
* output_collection, the currently active collection on the output of multiqueue

Handling GST_EVENT_SELECT_STREAMS is split, by looking for the collection to
which it applies. And the requested streams are stored in it. IIF that
collection is output_collection we can do the switch, else it will be updated
when it becomes active.

Detecting which collection/selection is active is done by looking at the
GST_EVENT_STREAM_START on the output of the multiqueue.

03febb5048 streamsynchronizer: Fix deadlock when streams have been flushed before others start
To simplify the description, I'm assuming we only have two streams: video and audio.

For the video stream, we have the following events :
- STREAM_START => stream->wait set to true
- NEW_SEGMENT(1) => blocked waiting in gst_stream_synchronizer_wait
- FLUSH_START => unblocked
- FLUSH_STOP => stream->wait reset to false
- NEW_SEGMENT(2) => not waiting, since stream->wait is false

Then for the audio stream, we have the following events :
- STREAM_START => stream->wait set to true
- NEW_SEGMENT(2) => blocked waiting in gst_stream_synchronizer_wait for ever.

Note: The first NEW_SEGMENT event and the FLUSH_START, FLUSH_STOP events of the audio stream
are dropped before being received by the streamsynchronizer element, because the decodebin audio pad src
is not yet linked to the playsink audio pad sink.

To fix this deadlock, we don't reset stream->wait to false in the FLUSH_STOP event when it is not
waiting for the EOS of the other streams.

8737b9ca84 playbin3: Handle combiner update in case of errors
The assertion that was present before is a bit too harsh, since there is now
a (understandable) use-case where this could happen.

In gapless use-case, with two files containing the same type (ex:audio). The
first one *does* expose a collection with an audio stream, but decoding
fails (for whatever reason).

That would cause us to have configured a audio combiner, which was never
used (i.e. not active).

Then the second file plays and we (wrongly) assume it should be activated
... whereas the combiner was indeed present.

Demote the assertion to a warning and properly handle it

24c0dc9602 parsebin: Ensure non-time subtitle streams get "parsed"
Since https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/6153 ,
subtitle "decoders" (i.e. which decode to raw text) are no longer auto-plugged
by parsebin.

But if a given format does not have a parser at all, we would end up outputting
non-time/non-parsed outputs.

In order to mitigate the issue, until such parsers are available, we check if
the subtitle stream is in TIME format or not (i.e. whether it comes from a
parser or demuxer). If not, we attempt to plug in a subtitle "decoder".
