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.

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.

493d47dca3 typefindfunctions: Extend MCC typefinder to also cover version 2.0
Both versions are basically the same, but version 2.0 also allows
60000/1001 as framerate and allows to specify the field and line number
for each payload.

Put the major version into the caps so that elements can limit via caps
negotiation which versions they can support.

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
now be specified.

We now call gst_base_transform_set_passthrough dynamically, based
on the return from the new gst_audio_converter_is_passthrough()
API, which takes the mix matrix into account.

8b69b689c0 urisourcebin: limit the byte size of the queue based on the buffer-size
Use the bitrate advertised by queue2 to determine the limits to
set across possibly multiple queue2/downloadbuffer elements.  e.g.
with two queue2's and a max-bytes based on the ratio of the
bitrate/cumulative_bitrate multiplied by the buffer_size set on urisourcebin.

This allows finer grained control over the buffer used by all the queue
elements inside urisourcebin.  Instead of a maximum of
n_streams*buffer_size being used, only buffer_size will be used however
we will fallback to n_streams*buffer_size if one of the queue2's does
not have bitrate information.

e87fa73e60 compositor: Implement different operators via per-pad property
This removes the crossfade-ratio property and replaces it with an
operator property. Currently this implements the following operators:

- SOURCE: Copy over the source and don't look at the destination
- OVER: Default blending of the source over the destination
- ADD: Like OVER but simply adding the alpha instead

See the example for how to implement crossfading with this.

62e4e15245 playsink: audio visualization support fixes
The queue between the audiotee and the audio chain wasn't properly added to the

visualization chain wasn't working as expected either. It is now possible to
dynamically enable/disable the audio visualization support.

aa3e64c71d compositor: Use 255 as maximum alpha instead of 256
255 will easily become 0 in the blending function as they expect
the maximum value to be 255.

Can be reproduce with

gst-launch-1.0 videotestsrc pattern=ball ! c.sink_0 \
               videotestsrc pattern=snow ! c.sink_1 \
               compositor name=c \
                 sink_0::zorder=0 sink_1::zorder=1 sink_0::crossfade-ratio=0.5 \
                 background=black ! \
               videoconvert ! xvimagesink

crossfade-ratio +/- 0.001 makes it work correctly and the same happens
at e.g. 0.25, 0.75, N*0.0625

a498d3fe6e adder: remove non-interleaved layout from caps
adder needs more than just trivial work to support planar buffers properly
because it currently reads sub-buffers from GstCollectPads in order for all
of them to have matching sizes. In planar mode, this means it would truncate
some channels and mix them up in strange ways. It only works if all input
buffers in all sink pads have matching sizes.
