errno should be set to the positive errno value.
This does not cause problems except for the pulse-server where the
errno value is negated and returned as an error result.
Use the same code to enumerate the profiles and the current profile,
this makes sure we have all info in the Profile param as well and
don't need to do a lookup in the EnumProfile.
Use the DSP media subtype to describe DSP formats. DSP formats
don't include the rate, channels and channel position in the
format and must use the rate and duration from the position io. This
makes it possible to later change the samplerate dynamically without
having to renegotiate the graph.
The same goes for the video DSP format, which uses the io_video_size
from the io_position to get the size/stride. Set this up in the node
based on the defaults from the context.
Make it possible to define defaults in the daemon config file, such
as samplerate, quantum, video size and framerate. This is stored in
the context and used for the DSP formats.
This is more in line with wayland and it allows us to create new
interfaces in modules without having to add anything to the type
enum. It also removes some lookups to map type_id to readable
name in debug.
Add some padding, tweak some padding
Remove count in the clock, it's useless
For video frames we will want to use metadata to place
this on individual buffers.
This makes it easier to keep track of who is responsible for what.
Also remove the valid fields and move them to flags in the segment
info. That way, the owner can update the flags without having to
worry about concurrency.
Keep separate info for the reposition information. We need to do this
to make it possible to seek in other formats than the frame.
Clear out the owner field when the node is destroyed or removed from
the driver.
Move fields from the io_position to io_segment. The segment contains
the mapping between raw clock time and stream time in various
formats. We keep an array of pending segments available in the
io_position field so clients can anticipate changes.
Make looping a flag in the segment instead of a state.
Prepare for segment masters. These will be registered clients that
are responsible for updating parts of the extended segment info.
Add namespace to some defines.
Move some things around. Move the duration of the current cycle
to the clock. Also add the estimated next timeout to the clock.
Add a generic media specific counter to the clock.
Clean up the position_bar info. We can do with only a double beat
value and make the signature in floats.
Flesh out the io_position info. This has now the information needed
to convert a raw clock time into a stream time. It basically has
the same kind of features as GStreamer segments such as looping,
variable rate playback etc.. It also contains the state of the
timeline (paused/playing) and it can be used to update the position
and state from clients.
There is also extended information in the position field that
clients can update when they can.
Plugins basically only update the clock info they get (and use
the position info to check if they are slaved or not).
Before each cycle, check if there is a pending position update and
apply it.
Makes a device with a source and sink that automatically
proxies all physical ports from jack. Jack then drives our
PipeWire pipeline from its own thread.
