When using a filter, it makes more sense to use the default value
of the filter as a first attempt.
One case is in adapter when we try to find a passthrough format first. The
audioconverter suggests a default rate of the graph rate but the follower
filters this out for another unrelated default value and passthrough is not
possible (altough it would be because the default value of the filter is
in the supported follower range).
Fixes#4619
When parsing the graph, parse the input and output port names into
a separate string array. This was we can keep them around when
setting up the graph.
Instead of setting up the graph right after loading it, do the graph
setup when we activate the graph. This makes it possible to pass the
input channels to the filter-graph and let it create the right amount of
plugins and ouput channels.
When setting up the graphs in the audioconverter, pass the current
number of channels as the input to the graph and keep track of the
channels that each filter produces.
This way we can also load a custom upmix or downmix graph, for example.
When the pod to filter is in the target builder memory and reallocation
is needed, make sure we refer to the filter in the reallocated memory
instead of the old freed memory.
Fixes#4445
Report the "fractional" part of the resampler delay in
spa_io_rate_match::delay_frac, in nanosamples (1/1e9 sample) at node
rate.
The delay values are best reported in units where it is clear what the
clock domain is, so report the value in fractional samples instead of
nanoseconds. Conversion to ns is also just dividision by the appropriate
rate.
In timestamps, support different clocks and local time as formats.
Local real time timestamps are useful when trying to correlate logs from
different sources.
Remove the chunk and add separate arrays with data and n_samples. This aligns
better with other methods and makes it possible to more easily reuse
arrays of pointers as input and output.
Both `spa_rectangle` and `spa_fraction` store unsigned numbers,
so print them as unsigned, the same way it is already done in
`spa_debug_strbuf_format_value()`.
When api.alsa.split-enable=true for ACP device, instruct UCM to not
use alsa-lib plugins for SplitPCM devices.
Grab the information from UCM for the intended channel remapping, and
add the splitting information to the nodes emitted.
Session manager can then look at that, and load nodes to do the channel
splitting.
What may be NULL in these methods is the pointer to the object
containing the spa_interface, not the interface pointer itself.
Fixes spa-acp-tool crashing with NULL deref in spa_i18n.
Some clocks (v4l2) don't process exactly process buffers at the given
rate/duration so mark this in the clock flags.
We need to use the nsec field in the clock to derive ticks in pw-stream
in that case to get a good clock.
Add a filter-graph info structure with the number of inputs and outputs
in the graph definition.
Use the input/outputs to update the number of channels on the capture and
playback streams when not explicitly given. Also copy over the positions
when they match the other stream and were not explicitly specified.
Fixes#4404
In our current world, it is possible to have a negative delay. This
means that the stream should be delayed to sync with other streams.
The pulse-server sets negative delay and the Latency message can hold
those negative values so make sure we handle them in the helper
functions as well.
Do the delay calculations in pw_stream and JACK with signed values to
correctly handle negative values. Clamp JACK latency range to 0 because
negative latency is not supported in JACK.
We should also probably make sure we never end up with negative
latency, mostly in ALSA when we set a Latency offset, but that is
another detail.
Add a new followerClock block in the profiler info. This is only set
when the follower could be a driver and it contains the clock info used
for following the driver, mostly the rate difference and delay.
Dump this info in pw-profiler -J
Make sure we always set the info in the clock, especially also when we
are following.
The bar can start from 0 in JACK.
Add bar_start_tick and ticks_per_beat to the io_segment_bar so that we
can losslesly store the complete jack BBT values.
See #4314
Make a function that can initialize raw audio info from a dict and fill
in the defaults. We can use this in many of the modules when the audio
format is parsed.
Use the helper instead of duplicating the same code.
Also add some helpers to parse a json array of uint32_t
Move some functions to convert between type name and id.
This gets the next key and value from an object. This function is better
because it will skip key/value pairs that don't fit in the array to hold
the key.
The previous code patter would stop parsing the object as soon as a key
larger than the available space was found.
Add spa_json_begin_array/object to replace
spa_json_init+spa_json_begin_array/object
This function is better because it does not waste a useless spa_json
structure as an iterator. The relaxed versions also error out when the
container is mismatched because parsing a mismatched container is not
going to give any results anyway.
