Add a new PortConfig parameter to configure ports of elements that
are marked with the SPA_NODE_FLAG_*_PORT_CONFIG. This is used to
configure the operation of the audioconver/audioadapter nodes and
how it should convert the internal format. We want to use the
Profile parameter only for cases where there is an enumeration of
values, like with device configuration.
Add unit tests for audioconvert and adapter to check if they handle
PortConfig correctly.
Make the media session use the PortConfig to dynamically configure
the device nodes.
Remove audio-dsp, it is not used anymore and can/should be implemented
with a simple audioconvert spa node now and some PortConfig.
Remove the node buffers reply again. We don't need it. Instead add a
new method to the client-node to upload an array of buffer datas.
This method is called after the client has allocated buffer mem. It
will update the buffers on the server side with the client allocated
memory.
Wait for the async reply of use_buffers when doing alloc_buffers so
that we can get the updated buffer mem before we continue.
Let the link follow the states of the ports.
Add some error code to the port error states.
Add PW_STREAM_FLAG_ALLOC_BUFFERS flag to make the client alloc buffer
memory.
Remove the CAN_USE_BUFFERS flag, it is redundant. We can know this
because of the IO params and buffer params.
Add flags to the port_use_buffer call. We also want this call to
replace port_alloc_buffer. Together with a new result event we can
ask the node to (a)synchronously fill up the buffer data for us. This
is part of a plan to let remote nodes provide buffer data.
Add a tag field when creating a memmap so that we can do lookup on it.
This makes it easier to implement the tracking of mappings for io areas.
Remove custom io memory tracking and use the tags.
Add flags to spa_chunk to make data corrupted. The flags on the buffer
stay constant for the life of the buffer. Add flags to mark memory
readable and writable. Mark memory readonly in v4l2-source.
Pass the daemon activation area to the client in the transport event.
This never changes and need to be handled differently from the other
activation areas.
Use the right flags when importing memory.
Add the (desired) memory type to mempool_alloc.
improve some debug.
Track memory on buffers in the server and simplify some memory tracking
on the client.
Don't send internal memblock flags to client.
Add read/write flags to memblock.
Use a new rate_match io area to exhange rate matching info between
sink/source and resampler.
Compensate for the rate match delay when scheduling timeouts.
Let the resampler notify the source of how many samples it needs to
produce the desired quantum. Make sure we keep an extra buffer in
the device to be able to make this possible.
Let the adapter directly call the slave node process function.
spa_pod_builder_frame() should return the position in the builder
memory or NULL when the frame doesn't fit. Check the size of the
frame instead of assuming the frame is already written to the
buffer.
Define a set of standard factory names and document what they
contain. This makes it possible to change the implementation by
mapping the factory-name to a different shared library.
Move the epoll functions to the system functions and make the loop
use those. Use simple mask for events instead of enum.
Add the used system api in pw_loop.
Add System API to spa_support and use it where possible.
Pass the system API used in the realtime loops in spa_support as
well and use this in the realtime paths.
Improve bootstrapping, load only the log and cpu interfaces because
those can/need to be shared between instances. Let the core load
the other interfaces.
Add keys to configure the System and Loop implementations used in
pw_loop.
Make a new API to hide some the implementation of eventfd, timerfd
and signalfd along with clock and read/write/ioctl/close functions.
We would like to have plugins use the abstractions so that we
can switch them to something else when needed.
Pass a factory_name in the object_info of monitor and device.
Restructure the factory name to mean something functionaly. With
the factory to library mapping this then means that the implementation
of certain factories can be configured in the config file.
The interface struct has the type,version and methods of the
interface.
Make spa interfaces extend from spa_interface and make a
separate structure for the methods.
Pass a generic void* as the first argument of methods, like
we don in PipeWire.
Bundle the methods + implementation in a versioned inteface
and use that to invoke methods. This way we can do version
checks on the methods.
Make resource and proxy interfaces that we can can call. We
can then make the core interfaces independent on proxy/resource and
hide them in the lower layers.
Add add_listener method to methods of core interfaces, just
like SPA.
