work on stream negotiation and start Add more buffer types to add and remove memory shared memory between the server and client. We would like to send buffers only once and then simply reference them by index. Do format negotiation and stream start with a START message.

Rework transport protocol Use a more simple tranport protocol for the realtime data. Use a piece of shared memory and a socket where we use a 1byte read/write to trigger remote actions. Also use a ringbuffer for events.

Work on main loop Make a main-loop object with associated helper functions to handle async methods. rtloop -> data_loop Handle async results a lot better. Remove REMOVE_MEM command. We don't need it. Handle stream memory updates better.

More hacking 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

Make PinosPort struct Keep track of the ports, their links and the allocated buffers in a small struct managed by the node.

Remove port Remove the port object. We don't use it as a dbus object and we don't need it, we can use the link and node object directy. Move poll code and event handler to the node.

PinosSignal port_unlinked;

More hacking 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.

uint32_t queue[64];
Remove some events 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
