Remove calls to gst_pad_has_current_caps() which then go on to call
gst_pad_get_current_caps() as the caps can go to NULL in between. Instead just
use gst_pad_get_current_caps() and check for NULL.

If we have an error during fwrite call, file stays open and thus next
incoming buffer will trigger an assert when trying to opening a new
file.
This happens if we do not restart element, file is closed at stop, and
if application handles the returned GST_FLOW_ERROR to keep bin alive.

Such files will not play on Android, because of bug in libwebm matroska parsing, which is still present in 6.0.1

https://bugzilla.gnome.org/show_bug.cgi?id=761489

This block is needed in the Matroska file, but data coming from
RTP may not have one.

... as streams are so ordered by id by e.g. decodebin
(and as typically already honoured by other demuxers).

VP9_PAY_PICTURE_ID_7BITS and VP9_PAY_PICTURE_ID_15BITS are mutually
exclusive options of the picture-id-mode. We can break after the
first case.

1 or 2 bytes need to be added to the header length depending on the
PictureID size.

This hasn't been touched for generations, doesn't work,
and is just causing confusion. We also don't want to
maintain these files manually.

Instead of erroring out, just use the default color table.

Set GSETTINGS_BACKEND=memory, apparently there's something
about fork() and the dconf backend (or whatever else that
drags in or activates) that messes up locking and causes
timeouts due to deadlocks in g_mutex_lock(), since
everything works fine with CK_FORK=no as well.

Otherwise it will be mapped writable all the time and we can't read from it
anywhere.

Commit 7873bede
(https://bugzilla.gnome.org/show_bug.cgi?id=760774) changed the
behaviour of qtdemux to call gst_qtdemux_configure_stream() for
every new moof.

When playing a protected stream, gst_qtdemux_configure_stream()
calls gst_qtdemux_configure_protected_caps(). The
gst_qtdemux_configure_protected_caps() function takes the original
media format, puts this in a field called "original-media-type"
and then changes the caps to "application/x-cenc".

The gst_qtdemux_configure_protected_caps() did not handle the case
of being called multiple times, causing it to incorrectly set the
caps. The second call was causing the caps to be set to:

    application/x-cenc, original-media-type"application/x-cenc"

This commit makes gst_qtdemux_configure_protected_caps() check that
the caps have already been transformed, so that it only gets
changed once.

Send GAP events for non-subtitle streams too if they lag too much
behind, but use a higher threshold than for subtitles.

This helps with fixing prerolling with a file where one of the
audio streams only has data starting from 19s onwards. It's not
a complete fix yet, it also requires changes elsewhere, such as
in baseparse, to make sure caps are propagated.
