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.
Make it possible to have a mixer/spliter and converter for the gstreamer
sources and sinks.
Add logic to make a new input/output port when the existing ports are
not of the required format.
Make a property to limit the number of peers on a port. By default we can
link an output port multiple times (with the same format) but we can only
link to an input port once (else we would have to do mixing).
Use a pointer array to keep track of peers
The GstNodeFactory creates GstSource nodes without ports. When an
output port is created later, the proper GStreamer element will be
created in the node.
main.c registers a GstNodeFactory in the daemon, so clients can use it
in calls to CreateNode and CreatePort.
Add to GstSource the possibility to create the GStreamer element
when an output port is created, and not directly when the node is
created.
The element is chosen based on the requested format, using
GStreamer typefind as in the GstAutoDetect class.
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.
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.
