Make separate payload for the header.
Make release-fd payloads
capture_buffer -> peek_buffer to avoid a copy
remove release-buffer, we really need to release each fd in the buffer
separately.
provide_buffer -> send_buffer so that we can also use this to send the
release-fd messages.
in pinossrc, send back release-fd messages when the fd is no longer in
use.
Rename the payloader and depayloader to pinospay/pinosdepay because they
now store data in a pinos specific format.
Subclass GstElement because they are not real transform elements.
Rework/remove some buffer functions that are not used by some more
performant ones.
Use BufferIter and BufferBuilder instead of Packet*
Make separate method to set the header so you can set it later and not
only at builder init time.
Add method to clear the builder if you want to abort.
Add method to add fd to builder instead of in _add_fd_payload. This
would make it easier to add multiple fd-payloads using data from the
same fd.
Pass PinosPacketFDPayload to add_fd_payload to make it symetric with the
parsing code. We should be able to get the size from the VERSION passed
when the builder was made.
Add ideas about releasing the fds back to the server.
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.
