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 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 a link state
Add error quark
Track the state of node we create and error when it is in error.
Handle stream error states when negotiating
Make the node error when a link is in error
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.
Rework things so that we negotiate buffer pools beforehand and only pass
buffer ids around We can then remove the refcount of buffers, events and
commands.
More work on buffer reuse
Use the node state changes to trigger the next step in the configuration
sequence.
Move most of the client-node to a plugin
Do buffer allocation in the port link.
Bring back the channel object. Making a node and port on the client side
was rather awkward because of the async nature of many methods. It feels
better to have a specific communication channel object to interface with
a server side port.
Use port activate/deactivate to start/stop streams
Remove links from the ports. We let other objects install a callback on
the port to receive and route buffers.
Remove the client object, it is not very useful now that we have the
nodes.
Fix some properties on the proxy objects.
Use sendmsg and recvmsg directly because the GIO ones do allocations.
make pinos_properties_merge and use it to combine properties from nodes
and ports.
Add buffer flags. The idea is to make it possible to easily check when a
buffer contains control information that we need to parse to update the
port fields.
Make the client create remote nodes and ports and set up proxies for
them.
Make a port base class implementing most of the logic to pass buffers
locally and remotely.
Remove most code from stream.c, it's now in the port.
Make a portsink and portsrc that can write and read to/from any port. We
use these in the server to send and receive data.
Rework format negotiation. The final format is now sent in-line before
the data. The server will select a format on output ports.
A port is an input or output on a Node.
Channels are created from the ports and inherit the direction of the
port.
do automatic port selection based on the direction and caps and
node/port name.
Simplify stream_connect by passing the direction.
Fix pinossink to connect in setcaps so that we know the format and can
select a good sink to connect to.
Rename the source-output object to channel because it is used for both
input and output.
Start the beginnings of sink support. This will make it possible to make
pinos consume data as well as provide data.
