a0a54303cb typefind: Fix handling of ID_ODD_SIZE in WavPack typefinder
Chunks are always starting on an even position and this flag only
specifies that the last byte of the chunk is not valid.

32e077cb67 typefind: Handle WavPack block sizes > 131072
These are valid nowadays.

Also handle ID_ODD_SIZE and ID_WVX_NEW_BITSTREAM. The parser already
handles the former but not the latter.

Don't reset the last_ts if only the caps have changed. This fixes issues
if you have a stream without only first frame with TS=0, and have resolution

described in #1352. The reported issue is still fix after this change.

eea9f74f95 decodebin3: Fix slot input linking when the associated stream has changed
Setting the input field on the empty slot prevents future linking of it and will
result in flow errors later on.

This was observed in WebKit's MediaStream source element, when it changes the
caps on one of its associated streams, from an encoded format to a raw video
format. The associated stream-id on the sticky stream-start event doesn´t
change, but the element creates a new GstStream with a different ID and sets it
on the stream-start event. Stream parsing is disabled in urisourcebin, so
decodebin3 handles the parsing. Without this patch we would end-up with unlinked
pads in decodebin3 after switching to the raw video format.

1ee26b0a7a urisourcebin: Set source element to READY before querying it
Generating the source element is done when urisourcebin is doing the READY to
PAUSED state change, so it is reasonable to set the new source element to that
state.

This also allows detecting early failures with backing libraries or
hardware (checks done in NULL->READY).

Finally it makes more sense to have an element in READY when attempting to query
information from it (such as SCHEDULING queries or probing live-ness).

Previously when fixing up subrip markip, we were looking from the start
of the remaining buffer instead. Due to how skipping over closing tags
works, the remaining buffer will still contain the closing `>` of the
previous tag so if a unexpected closing tag is found after another
closing tag, we would potentially do an out of bounds memmove().

dd6e889073 streamsynchronizer: reset eos on STREAM_START
self->eos was never reset after streamsynchronizer has sent EOS
(except on explicit flush or switching back to PAUSED).
As a result, synchronization was broken if new streams were pushed later
as gst_stream_synchronizer_wait() does not wait if self->eos is set.

Fix this by reseting self->eos on STREAM_START as that means a new
stream is being sent upstream and so a new EOS will follow later on.

fcd4085c25 decodebin3: Handle streams without CAPS or TIME segment
decodebin3 will do its best to figure out whether a parsebin is required to
process the incoming stream.

The problem is that for push-based stream it could happen that the stream would
not provide any caps, resulting in nothing being linked internally.

Furthermore, there is the possibility that a stream *with* caps would not be
using a TIME segment, which is required for multiqueue to properly work.

In order to fix those two issues, we force the usage of parsebin on push-based
streams:
* When the pad is linked, if upstream can't provide any caps
* When we get a non-TIME segment

02a8e4bb4c parsebin: Improve elementary stream handling
The goal of parsebin is to figure out which elements to link together in order
to provide elementary streams given any random input.

The problem is that deciding whether a given stream should still have more
elements plugged in or not was dependent on ... the presence of compatible
decoders (sic).

Instead of that, if we can't plug anymore elements on a given stream *and* it is
detected as being an elementary stream, expose it.

* When inputs are unlinked they weren't always properly resetted (it would only
  work if parsebin is used, which is no longer the default in
  uridecodebin3/playbin3).
