Make explicit links between elements that are used to activate the
next element in the graph.
Make subgraphs a special regular node. Make a link from the
subgraph children to the parent so that the subgraph completes when
all the children completed.
Implement a single process function in plugins
Remove many messages in the client node
Add control properties to audiotestsrc for frequency and volume
and add a test program.
Add size parameter to set_io for additional checks and to make it
easy to know how much control data we can write.
Make it possible to configure multiple io areas on a port by giving
an id to set_io.
Add some types to enumerate the supported ids
Make an area to exchange buffers and one to specify pull ranges.
The idea is to make more area types for controlable properties.
Implement enumeration of IO areas in volume.
Reset the builder when the filter failed.
Make the plugins create their params in a temporary buffer, we
don't want to do in-place filtering because that is not always
possible. Because the filter now resets on error, we can remove
the reset from the plugins.
Add an argument to pass the result param to the caller instead of
having the caller have to pick it up from the builder.
Improve docs for node, clock and monitor
Pass spa_pod everywhere instead of spa_pod_object.
Pass result argument to spa_pod_filter to make things a little
nicer.
Make enum_params and set_param to configure properties, format
and other parameters. This allows us to remove some duplicate
code and make the properties and parameters much more extensible.
Use the object id to mark the id of the parameter.
Remove the spa_format and spa_props.
We can now make the client-node easier by merging the various
format methods into the params.
Make the stream API more powerful now that we can pass params
around.
Make a new method that can take a local node and run it in a remote
pipeline. This basically replaces all functionality of the streams
and more.
Add 2 examples for exporting a sink and a v4l2 node
Make some more things const
Cleanups
Make it possible to do things when the node needs scheduling. The
default node will schedule the local pipeline but the remote node might
also schedule the remote pipeline.
Remove port properties and replace them with port params. Move the
params from the PortInfo to enum_params.
Use the Param ranges to specify possible sizes etc.
Remove the node state. The state of the node is based on the state
of the ports, which can be derived directly from calling the port
methods. Track this state in the Port instead.
Add a mixer module that puts a mixer in from of audio sinks. This allows
multiple clients to play on one sink (still has some bugs). do some
fixes in the mixer and the scheduler to make this work.
Unify input and output io areas.
Add support for ranges in the io area.
Automatically recycle buffers in the output areas in process_output
Improve the mixer, add use_buffer support, use a queue of input buffers,
fix mixing, add support for ranges.
Fix mixer and v4l2 tests
Make allocparams into pod objects. This makes it easy to serialize,
copy, create and intersect them.
Add convenience macros for properties
Add helper function to collect object properties.
Use a POD for the format body. This allows us to more easily build
and copy the formats.
Remove obsolete code to make video and audio formats.
Use SpaVideo/AudioInfo to keep track of formats. Make functions to parse
the format into the structures.
Update plugins
Use counters instead of void* to iterate items. This simplifies some
things and makes it easier to do over the wire.
Add format description to NodeInfo and use this to add format
descriptions to pinos devices.
Small fixes to fix leaks and crashes.
We can optimize the transport some more if we allow the host to
configure the area used for transfering buffers. We can then also place
the current status in the area and avoid calling get_status(). We can
also allocate this area in shared memory, avoiding a memcpy in the
client-node.
Move array and map to pinos
Move more things to spa lib
ControlCmd -> Message
Make pinos log, use for plugins as well
work on ringbuffer in alsa and nodes
work on making registry with all objects
Remove unused events, drained and marker can be done with
ASYNC_COMPLETED messages
Handle result of idle callback to disable the poll item
Identify poll items with a unique id.
Remove set_state vfunc
push_event -> send_command, commands are to do something, events are the
result of something.
Add poll item in v4l2 as soon as we have the fd but disable the item
until streaming starts.
Add explicit DMABUF memory because we can't use it like an fd in v4l2.
mmap random fd memory and use userptr in v4l2 to use it.
Allocate buffer data memory in memfd when no node can allocate.
Improve debug some more
simplify port numbering again by using 0->max_ports for bot input ports
and output ports. This means we need to tall what direction the port is.
Add port_info serialize functions
Copy metadata and data when we are not sharing buffers.
Make pinossink work again.
Remove the memory stuff from the spa API, we can do thing more simple
and efficiently if we always allocate buffers outside of the plugins and
only implement an alloc function on the node when it can do something
clever.
Move serialize code to the props/format/buffer code
Make it possible to copy a format and properties.
Add an async result code and an event to signal the completion.
Use async return values to signal completion of a method and potential
state change.
Add selected format to port update message.
Make it possible to parse into a custom copy of the command memory.
Remove state change events from the elements, we now just update the
state.
Implement async results in the proxy element
Add support for removing buffers in the client.
Fix up pinossink
Deal with async return in the links.
Use the v4l2 monitor to dynamically add and remove nodes.
Use the info from the monitor as parameter for the factory init and use
it to configure the new node.
Add info to the node.
Use info from the factory as properties on the PinosNode
Add a clock interface to get raw clocking information from an element
Make events and commands to request and configure clock updates.
Add support for passing events and commands in control
Set the size of the buffers in pinossrc
Make events and command specific to the node
Remove some unused code
Improve state changes
Use easier fixate by just taking the element default value
Fix reuse buffer in the proxy
