Don't use special callback in node to receive the results. Instead,
use a generic result callback to receive the result. This makes things
a bit more symetric and generic again because then you can choose how
to match the result to the request and you have a generic way to handle
both the sync and async case. We can then also remove the wait method.
This also makes the remote interface and spa interface to objects very
similar.
Make a helper object to receive and dispatch results. Use this in the
helper for enum_params.
Make device use the same result callbacks.
Make a special function for pending results to make it clear that it
is different from normal results. Don't pass result code to result
function, it is not useful because since the callback is called, all
must be fine.
The spa_pending is removed from the list right before the callback
and can thus be freed in the callback. Pass the spa_pending in
the pending callback so that extra data can be added that way.
Reuse spa_pending objects in link and nodes instead of allocating. We
always only have one pending operation and we can cancel any pending
previous operation by removing the pending.
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.
Add a port_info event. With this, we get updates to ports pushed to
us, which is more convenient and also allows for better dynamic
add/remove of ports.
We don't need to the PortChanged event anymore
We can remove the get_port_ids/get_n_ports/port_get_info methods.
Update plugins
Improve the allocators to always align the buffer memory to the
requested alignment
Use aligned read and writes for sse functions and check alignment,
optionally falling back to unaligned path.
Add more tests and benchmark cases
Check and warn for misaligned memory in plugins.
Automatically parse and build key/value when in objects without having
to prefix the key with ":"
Automatically build control/value when in sequence without the "."
prefix.
Remove the builder with key/pod, taking a reference to the stack built
temporary pods is not allowed in c++. We can use the varargs version
with the same convenient syntax.
Remove the parser "*" option, it is unused.
Improve spa_pod_builder_add_* and spa_pod_parser_get_* and make them
look similar.
Reorder channels to a more common default order.
Only add channel layout when channels > 1
Don't try to link to a session that is still starting
Small sse fixes.
Make special format types for planar and interleaved instead of
having a field.
Add enum for audio channel positions
Add some default audio channel layouts
Place the channel layout in the audio format when possible
alsa: place audio channel positions in format
Add sse optimized channel mixing for some common cases
Remove name from port info, it's not mandatory and in the properties
Add direction to port info
Only allow properties inside objects, this makes it easier to
iterate the object, which is needed for efficiently processing
control streams.
Add a choice type to mark variable properties.
SPA_TYPE_Enum -> SPA_TYPE_Id to avoid confusion with choice enum
Make it easier to allocate and initialize properties on the stack
Make more efficient methods to make objects.
SPA_ID_* -> SPA_TYPE_*. We use 'type' for all registered types.
ID refers to either a registered type or an enum.
Improve introspection of object ids. Make 0 an invalid enum and
use it to look up the object id type.
Move some type-info files together.
Swap type and id of the object, we first specify the type and then
the id because the meaning of the id depends on the object type.
Param ids and IO ids are now simple enums.
Move some type info in one place, delete some type-info files
Fix type debug
Make audio layout an enum
Mark more enums as enums in types so they show us with their names in
the debug.
Do not use dynamic types anymore. The reason is that it's difficult:
- to maintain a shared type database over a network.
- the extra overhead when translating between processes and for
maintaining the translation tables.
- race conditions in translating in RT-threads, this is a problem
because we want to make event streams.
We now have simple enums with types and extension points for all
types. This is also nicer to use in general.
We don't need the mapper anymore or pass strings around as types.
There is a parallel type info system to get more info about ids and
enums and their hierarchy. It can also be used for debugging.
Implement audioconvert as a complex element of fmtconver,
channelmix and resample.
Make copying resample just to test.
Plug the converter into pw_stream.
Separate buffer sizes in the info. Make it possible to not set
data pointers for when we use memfd for the memory.
Improve format conversion.
Work on in-place conversion in test-convert2
