5396ef6e45 subparse: do not assert when failing to parse subrip timestamp
If a badly formatted was passed into `parse_subrip_time` it would
assert instead of exiting gracefully. This is problematic since
the input is provided by the user, and will trigger a crash.

21d34edb1e pbutils: Add audio, base and video library to Requires line in the pkg-config file
We use all those libraries internally and include headers from them in
the public headers.

And add the tag library to Requires.private as we use it internally and
it would be needed when doing static linking.

b1df1000b1 glsinkbin: validate property in internal sink
It might be the case that glgsinkbin would try to set a property to
its internal sink which doesn't exist in it, leading to a glib's
warning. For example, when playsink sets 'force-aspect-ratio' property
and glsinkbin has, as internal sink, appsink, which doesn't handle
that property.

The patch validates the incoming property to forward to internal sink
if it exists in the internal sink and both properties has the same
type.

a6552ee02e video-converter: fix number of allocated lines
We make an allocator for temporary lines and then use this for all
the steps in the conversion that can do in-place processing.

Keep track of the number of lines each step needs and use this to
allocate the right number of lines.

Previously we would not always allocate enough lines and we would
end up with conversion errors as lines would be reused prematurely.

5767d65321 codec-utils: support extension audio object type and sample rate
ISO 14496-3 defines that audioObjectType 5 is a special case that
indicates SBR is present and that an additional field has to be
parsed to find the true audioObjectType.

There are two ways of signaling SBR within an AAC stream - implicit
and explicit (see [1] section 4.2). When explicit signaling is used,
the presence of SBR data is signaled by means of the SBR
audioObjectType in the AudioSpecificConfig data.

Normally the sample rate is specified by an index into a
table of common sample rates. However index 0x0f is a special case
that indicates that the next 24 bits contain the real sample rate.

c656cfb170 audiotestsrc: Improvements to the "ticks" wave
(Initially discussed in
https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/issues/305)

The ticks waveform can be useful for audio synchronization diagnostics
and other cases where the time offset between waveforms is important.
However, in its current form, it is too limited, and has problems with
discontinuities, which result in severe artifacts when this waveform
is output by a DAC.

This patch fixes some discontinuities and considerably expand the ticks
waveform's flexibility. They also introduce the notion of a "marker tick";
every Nth tick can have a different amplitude (usually one that is larger
than the others). This is useful for combining frequent oscilloscope
triggering with large time offset detection. For example, without marker
ticks, the tick intervals must not be too small, otherwise the maximum time
offset that can be unambiguously detected is quite small (for example, if
the interval is 50ms, then no time offset larger than 25ms can be
unambiguously recognized). If the tick intervals are too far apart, then
no sudden changes can be clearly observed, since the oscilloscope is not
updated quickly enough. But with marker ticks, this is not an issue: If
there's for example a tick every 100 ms, then the oscilloscope can be
triggered every 100 ms. And, if every 20th tick is a marker tick, then
time offsets of up to 1 second can be discovered, even though the time
between ticks is 100 ms.

The patch also applies some minor cleanup to the audiotestsrc documentation.

1edb2c4242 audio-converter: add API to determine passthrough mode
audioconvert's passthrough status can no longer be determined
strictly from input / output caps equality, as a mix-matrix can

API, which takes the mix matrix into account.
