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.
process_output is now to finish processing of the output in async nodes,
which means we need to fill the io area before sending the HAVE_OUTPUT
event. This simplifies some things and improves performance because we
don't need to deal with queues and additional checks.
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
Add connection message for PORT_COMMAND
Add rtkit support to ask for realtime priority
work on stream states and improve negotiation
Rework of port linking works, keep separate state for realtime threads
and use message passing to update the state.
Don't try to link nodes that are removed.
Open the device in the ALSA monitor to detect source or sink
Implement send_command as async methods on the plugins, use async
replies to sync start and stop.
Work on alsa sink.
Implement async PAUSE/START on v4l2 src. move the STREAMON/OFF calls to
the mainloop because they have high latency, add the poll descriptors
from the data loop.
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 the fd to the SpaData so that we can noth use the fd and the mmapped
memory when we want instead of needing to mmap again in the plugin.
various cleanups
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.
Enable the header metadata so that we have timestamps again.
Rework allocation in the link a little. Reuse previously allocated
buffers when possible. Keep track of where the buffers was allocated.
Make some more convenience functions to initialize buffer headers. Make
it so that we move allocations to the app.
Make some helpers to make memfd memory in pinos now that we will be able
to do all allocation there.
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.
Remove port added and port removed, we can get that info by inspecting
the port ids.
Remove data from ringbuffer, we just need the ringbuffer to keep track
of the read and write positions.
Handle async-complete in the main thread
Work on async node initialization
Work on using a queue as the link between nodes
Make the daemon link things based on the node states
Use queue helper in v4l2
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
