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
Sebastian Dröge
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.

023170e2f8 audioaggregator: improve readability in offset calculation 
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.

5fd4e71da3 audioaggregator: reduce variable scope 
This is a non-functional change that makes the code more alike to the previous
check. I should be more obvious when we drop a buffer.
