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.

#include <spa/ringbuffer.h>
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.
2016-11-07 10:24:13 +01:00
#include <pinos/client/mem.h>
Rework dbus handling Remove the Daemon object and remove all dbus code from the main objects. We can use the signals in a separate module to create and destroy the DBus interfaces. Move the dbus protocol in a module Move the autolink policy to a module

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.
