When we get worken up with a callback, mark ourselves as a master
because we then need to avoid running the converter again in the
process callback. After we perform the process callback, unmark
ourself as master and wait for the next cycle.
This fixes switch from master to slave for sources.
Move floatmix to the audiomixer plugin and change the name to
AUDIO_MIXER_DSP.
Add runtime selectable sse and sse2 optimizations.
Load the port mixer plugin dynamically based on the factory_name.
Add some more debug
Implement the device reservation DBus API.
When we acquire the device name, set our device profile to 'On'. This
adds our sources and sinks to the graph.
When we lose the name, switch back to 'Off' and remove our nodes
again.
Move the session mamager stuff in a directory.
Fixes#191
Remove the monitor API, we can use the device API for it. Make sure
we support creating devices (like alsa) from another device (udev).
Use new object.id to store the object id in the object properties. Use
the port.id/node.id etc to make relations to other objects.
start with a completely filled resampler so that the first
input byte immediately gives an output sample. When then have
n_taps/2 leading (almost) 0 samples.
Also make the passthrough resampler act like the real resampler
by introducing an n_taps/2 delay.
For very small buffer sizes, don't try to attempt to compensate
for the rate matching because we would come dangerously close to
the read/write pointers and cause dropouts. Instead this latency
should be reported on the ports later.
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.
