Remove the done and error callbacks. The error callback is in an error message. The done callback is replace with spa_pending. Make enum_params take a callback and data for the results. This allows us to push the results one after another to the app and avoids ownership issues of the passed data. We can then extend this to handle the async case by doing a _wait call with a spa_pending+callback+data that will be called when the _enum_params returns and async result. Add a sync method. All methods can now return SPA_RESULT_IS_ASYNC return values and you can use spa_node_wait() to register a callback when they complete with optional extra parameters. This makes it easier to sync and handle the reply. Make helper methods to simulate the sync enum_params behaviour for sync nodes. Let the transport generate the sequence number for pw_resource_sync() and pw_proxy_sync(). That way we don't need to keep track of numbers ourselves and we can match the reply to the request easily. |

PipeWire
--------
PipeWire is a server and user space API to deal with multimedia
pipelines. This includes:
- Making available sources of video (such as from a capture devices or
application provided streams) and multiplexing this with
clients.
- Accessing sources of video for consumption.
- Generating graphs for audio and video processing.
Nodes in the graph can be implemented as separate processes,
communicating with sockets and exchanging multimedia content using fd
passing.
Building
--------
Pipewire uses the Meson and Ninja build system to compile. If you're not
familiar with these tools, the included "autogen.sh" script will
automatically run the correct meson/ninja commands, and output a Makefile.
It follows that there are two methods to build Pipewire, however both rely
on Meson and Ninja to actually perform the compilation:
$ ./autogen.sh
$ make
or the Meson/Ninja native method:
$ meson build
$ cd build
$ ninja
You can see the available meson options in meson_options.txt file.
