When the port receives a format, look if we can find a mixer for it
and configure it.
Use the float32 mono mixer when possible.
Use the new pw_buffers in the link.
Let the port allocate buffers between the mixer and node when
requested.
The client-node doesn't need a mixer because mixing is done on the
client.
Remove all mixer and buffer negotiation code from adapter because
it is now done at the port level.
Implement the device reservation DBus API.
When we acquire the device name, set our device profile to 'On'. This
adds our sources and sinks to the graph.
When we lose the name, switch back to 'Off' and remove our nodes
again.
Move the session mamager stuff in a directory.
Fixes#191
This patch is fixing random crashes when vlc player connects rtsp.
we have two places to do link_activate, one is in node_activate(1),
the other one happens on link_paused(2).
The order of (1) and (2) can vary for each different connection.
Sometimes, (1) comes before (2); Sometimes, (1) comes after (2).
This will cause one crash in about five connections from vlc to
rtsp.
If link_paused(2) is earlier than node_activate, it will do set_io
and make activated=true, then when node_activate(1) comes, nothing
will happen:
int pw_link_activate(struct pw_link *this)
{
struct impl *impl = SPA_CONTAINER_OF(this, struct impl, this);
int res;
pw_log_debug(NAME" %p: activate %d %d", this, impl->activated, this->info.state);
if (impl->activated)
return 0;
...
}
In this case, everything works well.
If node_activate(1) is earlier than (2), it will do port_set_io, but
"activated" will still be false after port_set_io since the link state
can be not PW_LINK_STATE_PAUSED:
int pw_link_activate(struct pw_link *this)
{
struct impl *impl = SPA_CONTAINER_OF(this, struct impl, this);
int res;
pw_log_debug(NAME" %p: activate %d %d", this, impl->activated, this->info.state);
if (impl->activated)
return 0;
pw_link_prepare(this);
... // port_set_io
if (this->info.state == PW_LINK_STATE_PAUSED) {
pw_loop_invoke(this->output->node->data_loop,
do_activate_link, SPA_ID_INVALID, NULL, 0, false, this);
impl->activated = true;
}
return 0;
}
Then when link_paused(2) happens after (1), port_set_io will be done
again.
This will lead to random crash of pipewire.

After we grab the lockfile we should remove the socket when it
exists so that we can bind again. This should solve startup
problems after a crash, which left the socket around and caused
bind failures.
Remove the monitor API, we can use the device API for it. Make sure
we support creating devices (like alsa) from another device (udev).
Use new object.id to store the object id in the object properties. Use
the port.id/node.id etc to make relations to other objects.
Always add work to the work queue, some code relies on the fact that
the state change continuation happens from next iteration of the
mainloop.
Don't warn when destroying the work queue and there are still items in
it, this is ok.
Not closing the fd causes leaks in existing apps. It's probably better
to always close it and let apps deal with that by using dup or similar.
Make gst sink and source dup the fd before connect_fd().
