Base conf file path on sysconfdir. sysconfdir can be specified with an
absolute or relative path. To ensure PINOS_CONFIG_DIR is set correctly,
use join_paths() to prepend prefix when sysconfdir is relative.
Meson added support for sysconfdir in version 0.34.0 and join_paths() in
version 0.36.0.
It was sometimes assumed to be 0.1, sometimes 1.0, and sometimes not to
be used at all. This commit makes things consistent and so that it is
possible to link externally.
Use dynamic types for the data and meta types.
Move the meta into a separate header.
Remove port state, we can keep track of that ourselves.
Add size to MetaDataEnable params
Use absolute indexes that we let wrap around. We can then easily detect
how much we under of overflowed by using serial number arithmetic.
Remove the Areas, we can trivially compute this ourselves, move the
logic in read/write_data.
Rework the access checks.
Add owner field to more objects to do access control checks
Make sure the object global is set in the object before signaling the
new global.
In pull mode, schedule all upstream nodes first, if any of them
produce output, push it into the current node.
Underrun streams without input on audiomixer, avoids glitch when
starting a new stream.
Remove the node state. The state of the node is based on the state
of the ports, which can be derived directly from calling the port
methods. Track this state in the Port instead.
Add a mixer module that puts a mixer in from of audio sinks. This allows
multiple clients to play on one sink (still has some bugs). do some
fixes in the mixer and the scheduler to make this work.
Unify input and output io areas.
Add support for ranges in the io area.
Automatically recycle buffers in the output areas in process_output
Improve the mixer, add use_buffer support, use a queue of input buffers,
fix mixing, add support for ranges.
Fix mixer and v4l2 tests
