We can't allocate the shared meta in shared mem because then clients can
damage it for other clients. Place it instead right after the buffer
metadata array. Filter out the shared metadata for a client, we send it
as part of the client_buffer structure.
Remove pointer metadata, it's not so useful.
Document the layout of the allocated buffers and the shared memory.
Work on metadata to define control parameters
ringbuffer: remove size and mask from the ringbuffer, we have that
elsewhere in the user of the ringbuffer.
Remove the buffer data offset and size fields and replace with a
ringbuffer. We then have a ringbuffer in all buffer data, which
simplifies things.
We can now remove the ringbuffer metadata.
Reset the builder when the filter failed.
Make the plugins create their params in a temporary buffer, we
don't want to do in-place filtering because that is not always
possible. Because the filter now resets on error, we can remove
the reset from the plugins.
Add an argument to pass the result param to the caller instead of
having the caller have to pick it up from the builder.
Improve docs for node, clock and monitor
Pass spa_pod everywhere instead of spa_pod_object.
Pass result argument to spa_pod_filter to make things a little
nicer.
Remove the frame argument from the builder, we can use the builder
allocated frames.
Add deref function to builder to make it more flexible later.
Add some more recursion depth checks in the parser.
Improve props filter, also filter other types.
Make enum_params and set_param to configure properties, format
and other parameters. This allows us to remove some duplicate
code and make the properties and parameters much more extensible.
Use the object id to mark the id of the parameter.
Remove the spa_format and spa_props.
We can now make the client-node easier by merging the various
format methods into the params.
Make the stream API more powerful now that we can pass params
around.
Fix ringbuffer mixing in audiomixer
Add ringbuffer support in audiotestsrc params
Don't recycle buffers before signaling have_output, the app is supposed
to recycle explicitly or with a process_output call.
Add some trace to graph functions in tests
Add ringbuffer support in export-source
We can initialize the transport as soon as we get async notify
from the client when setup completes. Node initialization happens
after that and then finaly the node is initialized and we can send
the transport and fds.
Small cleanups
Make port status SPA_RESULT_OK until events changes it and data
processing can start
Only start pulling on ports in the OK state
Change we way we handle client-nodes, handle them async and continue
processing after they signaled completion
Add a new scheduler that decouples push and pull. It pushes to peer
elements when all inputs are provided and pulls from nodes when all
peer outputs are processed.
