1ec1123178 audioaggregator: Split getcaps() function into two
One for convert pads and one for normal sink pads.

0a21c28484 audioaggregator: Always take first configure pad's rate and downstream caps into account when calculating allow sink caps
While we can convert between all formats apart from the rate, we
actually need to make sure that we comply with a) the rate of the first
configured pad and b) also all the allowed rates from downstream.

bced52d2e8 audioaggregator: always use downstream's rate requirements
We were previously only fixating the rate in the getcaps
implementation when downstream was requiring a discrete value,
causing negotiation to fail when upstream was capable of rate
conversion, but not made aware that it had to occur.

Instead of fixating the rate, we can simply update our sink
template caps with whatever GValue the downstream caps are holding
as their rate field.

Allows negotiation to successfully complete with pipelines such as:

audiotestsrc ! audio/x-raw, rate=48000 ! audioresample ! audiomixer name=m ! \
audio/x-raw, rate={800, 1000} ! autoaudiosink \
audiotestsrc ! audio/x-raw, rate=44100 ! audioresample ! m.

31ac4f4665 gstaudioaggregator: expose output-buffer-duration-fraction
The code for this is mostly lifted from audiobuffersplit, it
allows use cases such as keeping the buffers output by compositor
on one branch and audiomixer on another perfectly aligned, by
requiring the compositor to output a n/d frame rate, and setting
output-buffer-duration to d/n on the audiomixer.

The old output-buffer-duration property now simply maps to its
fractional counterpart, the last set property wins.

0bf207aa53 audioaggregator: Also run the audio-specific caps fixation for audio aggregator subclasses that can't convert 2018-08-16 18:03:37 +03:00

320243050b audioaggregator: Fixate to some meaningful values if no sinkpad is configured yet
The default caps fixation code would select a rate of 1 for example,
which is not really ideal.

1b6eed694c audioaggregator: Properly propagate caps negotiation failures
Otherwise we'll end up doing a division by zero when clipping buffers,
and might even accept buffers for which we don't know the caps.

5b736d2c7a audioaggregator: Update converters after updating with the new audioinfo/caps
Otherwise subclasses might accidentially use the old audioinfo/caps.
None of the subclasses currently uses the audioinfo/caps, but future
subclasses might.

83939c81e7 audioaggregator: fix filtered getcaps
In the situation described in
https://bugzilla.gnome.org/show_bug.cgi?id=795397,

downstream_caps consists of two structures, the first with
the preferred rate, if at all possible (44100), the second
containing the full range of allowed rates, as audioresample
correctly tries to negotiate passthrough caps.

As audioaggregator cannot perform rate conversion, it wants
to return a fixated rate in its getcaps implementation,
however it previously directly used the first structure in
the caps allowed downstream, without taking the filter into
consideration, to determine the rate to fixate to.

With this, we first intersect our downstream caps with the
filter, in order not to fixate to an unsupported rate.

e9be107e4a audioaggregator: fix channel-mask negotiation
When outputting more than two channels, a channel-mask has to be
specified in the output caps.

We follow the same heuristic as other cases, when downstream
does not specify a channel-mask, we use that of the first
configured pad, and if there was none we generate a fallback
mask.

Don't reuse the offset variables will contain a sample offset for an
intermediate time value. Instead add a segment_pos variable of type
GstClockTime for this. Use The clock-time macros to check if we got
a valid time.

1b84283396 audioaggregator: remove buffer!=NULL check
Acording to the logic this cannot happen (we already check this before). So
add a assert like we do above and remove the check. This make it clearer that
we check for the offset range.
Also remove a dead assignment since we reassign this a few lines below.
