Keep the first active node as the fallback node. We use this node
as the target when no oher active nodes exist.
Only assign the target node to active nodes.
When we assign an unassigned node, simply update the active followers
of the target, the state of the nodes and target itself will then
be taken care of later.
When registering nodes, only active nodes can influence the state of the
graph.
Update some comments
Add reason to why we recalculate the graph for debugging purposes
Only recalculate graph when something relevant changed.
Block recalc from being called recursively.
Keep track of when a link is prepared, this is when the link has
successfully negotiated a format and buffers.
Only follow prepared links when collecting nodes in the graph.
Set the state of the driver and its nodes based on how many active
nodes the driver has. We don't have to do state changes on the nodes
from the link anymore then and we can get rid of the counters.
Only set the io on the mixer ports when prepared because we might
need a special mixer element based on the format.
Remove passive links for now.
This fixes many cases where the graph would stall when linking/unlinking
ports in various combinations.
Fixes#221
Rename (the non-exported symbol) _unref_id -> _remove_id and make it
remove the id from the map of known ids. This way, the server can send
the remove_mem and reuse the id for new memory before all references
are gone. Fixes "invalid mem id X, expected Y" errors.
Rework the metadata implementation without pw_properties to make
it easier to delete all subjects and implement the metadata API.
Remove metadata from all objects when they are destroyed.
When the resource does add_listener, send a message to the proxy
to trigger an emission of properties.
Block the client until all properties have been notified, track
this with a ping event to the implementation.
Make writable size more accurate by using the clock. mplayer uses this
to check if the clock is advancing.
Remove requested_bytes, we can use ready_bytes for the ready bytes
and use the queued bytes for playback.
Reset after a flush, wait for a new timing update.
Setting the size on input stream buffers based on the elapsed
ticks does not give a meaningfull value for the queue size so
just leave it to the user to set the size field.
The read_index should not include the delay to the device.
Keep a separate lis of memory blocks filled by the app and give
those to the stream when we can. This is because pulse can allocate
an infinite amount of buffers but we must cycle between a fixed
number. Use DYNAMIC_DATA to avoid memcpy.
Use the right requested_bytes in the write_callback. This should
be the tlength - the amount of bytes we already queued.
_get_time() should include the sink latency.
By default, the pipewiresrc tries to negotiate 16 buffers. This value is
hard coded in the pipewiresrc. If the buffers are large, this could lead
to an undesirably high memory usage. Applications that know about the
buffer size and that fewer buffers are sufficient should be able to
configure the limits for the number of buffers that are negotiated.
Therefore, add the min-buffers and max-buffers properties to the
pipewiresrc to enable applications to configure limits for the number of
negotiated buffers.
Make a new DRAINED status.
Place the DRAINED status on an input IO when a stream is out of
buffers and draining.
All nodes that don't have HAVE_DATA on the input io need to copy
it to the output io and return the status. This makes sure the
DRAINED is forwarded and nodes return DRAINED from _process()
DRAINED on the resampler flushes out the last queued samples and then
forwards the DRAINED in the next iteration.
Emit a new drained signal from the context when a node returns
DRAINED. Use this to trigger the drained signal in the stream.
