Add autoconnect property to the ports
Remove the upload-node, clients that want to upload media just create a
node with an (unconnected) output port. Other clients can then connect
to this new output port.
Copy formats on newly linked ports.
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 refcounting to buffers.
Use static memory on ports for buffer input and output memory.
Improve negotiation, let format and properties be negotiated on ports as
the data passes.
Improve some debug info.
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.
Make it possible to pass custom memory to the builder so that it can
construct packets directly into specified memory and avoid allocs.
Remove GError and GSocketControlMessage in the buffer API to make it
possible to use other (rt-safe) API later.
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.
Make an object for a processing node.
Implement a sink node. Make it possible to implement Sink and Source
interfaces to provide input/output from the node.
Improve pinosdepay to track fds and handle format changes.
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.
Only go to READY in setup_pipeline, this is enough to get the caps. We
don't want to go to PAUSED yet because we don't want to negotiate a
format.
Mark the source busy after we configured the capsfilter so that we can
let the source negotiate correctly.
Send the base-time to the client so that it can calibrarte the clock.
Wait until we are completely negotiated before completing the state
change to paused. This makes it possible to provide a clock and decide
if we are live or not.
Add a new refresh message to request a keyframe from the pinos server.
pinospay: pass the refresh-request message upstream
pinossink: turn refresh-request messages into events
pinossrc: turn a keyframe event into a refresh-request message
Detect a format change in the payloader and post an element message.
Catch the format change element message in the client-source and use it
to update the format and possible formats in the source and source-outputs.
Add a global object that can be used to track outstanding fds for a
client. This can later also be used to limit the number of fds per
client.
Use this in the payloader to track fds. This makes it possible to track
the fds even when the client reconnects.
Set the client patch on the socket so that we can use it to track the
fds we sent to this client.
When the client disappears, release all outstanding fds.
Rework stream connect/disconnect from start/stop
Start the stream in setcaps when the format is known.
When the stream is already started in setcaps, send a format_change
message instead.
Make sure we unref the source-input when it is removed.
When the source-input is removed, we should also unref the source. Do
this by adding the source as data for the source-input and unreffing it
when the source-input is freed.
