Send a command stream over the socket.
Implement a new buffer object that holds the data and commands.
Make iterator and builders to parse and construct buffers.
Rework gstreamer elements to use new API for creating and parsing
buffers.
Add _release_buffer to notify a stream when we are done processing the
buffer. This will eventually go all the way to the server and will allow
us to do more complicated buffer management.
Split setup of pipeline and state change to inspect the pipeline formats
and properties. Pass the device monitor caps to the gstreamer source so
that we don't have to query that again.
Work on adding time provider to the sender pipeline. Send the port and
address to the client in the source-output object properties.
Improve properties API and add some more docs.
Add instrospection of client and source-output.
Add properties to source-output and to CreateSourceOutput/Input
Add helper to fill properties of context.
Add client-name to pinossrc and pinossink
Improve test-subscribe to show all new introspection details.
Set the active device providers as a property on the daemon. In the
device monitor we can then obsolete the already monitored devices.
Copy all device properties to the source. Set the device class as
a property on the monitored devices.
Keep the client-source in the playing state for as long as the input is
streaming. Pausing the pipeline when there are no more readers causes
data to bunch up in the socket that gets bursted to new clients when
they connect.
Set the format on the client source when it is created so that other
clients can inspect the format. It also makes client sources show up in
the device monitor.
Add a mainloop wrapper that runs the mainloop in a separate thread and
has some synchronization primitives.
Use new mainloop in gstreamer source and sink elements
Emit all notify in the context thread.
Handle error cases better.
Make sure we hold the lock when running the mainloop, this will cause
all of the signals to be emited with the lock. Make sure we call all
methods with the lock.
