- Update to version 1.2.0:
* This is the 1.2 release that is API and ABI compatible with
previous 1.1.x and 1.0.x releases.
* This release contains some of the bigger changes that happened
since the 1.0 release last year, including:
- Support for asynchronous processing has been implemented.
Nodes can choose (or be forced) to be scheduled
asynchronously. The graph will not wait for the output of the
node to continue processing but it will use the output of the
previous cycle (or silence) instead. This adds one cycle of
latency but it can avoid having some nodes blocking the
processing graph. Non realtime streams and filters now also
use this asynchronous processing instead of their own
slightly broken version.
- The concept of node.sync-group was added. This groups nodes
with overlapping sync-group together when one of them sets
the node.sync = true. This is now used to make sure all nodes
are scheduled together when JACK transport is started so that
they all see the same transport time.
- Config parsing errors are reported earlier and much better
with line and column numbers where the parsing started to
fail.
- Add support for mandatory metadata when negotiating buffer
parameters. This can be used to only negotiate extra buffer
planes when certain metadata is negotiated. One use case is
the explicit sync support that requires 2 extra fds for the
timelines.
- Explicit sync metadata and support was added.
- Support was added for making and using multiple data-loops
in the server and clients. Support for CPU affinity and
