Remove port properties and replace them with port params. Move the
params from the PortInfo to enum_params.
Use the Param ranges to specify possible sizes etc.
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.
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
Make allocparams into pod objects. This makes it easy to serialize,
copy, create and intersect them.
Add convenience macros for properties
Add helper function to collect object properties.
Fix selection of the default property value by restricting it to
something in the valid range of the property.
Fix audio/videotestsrc reuse
Fix format enum with filters.
Fix module property configuration
Fix connection refill
Use a POD for the format body. This allows us to more easily build
and copy the formats.
Remove obsolete code to make video and audio formats.
Use SpaVideo/AudioInfo to keep track of formats. Make functions to parse
the format into the structures.
Update plugins
A sync message returns a notify-done after all request are finished and
can be used to wait for completion of a bunch of commands. Use it wait
for all proxy BIND requests to complete so that we can look at the
info immediately.
Copy the default value of unset properties.
Only send a buffer when we have received a NEED_DATA message.
Add a signal to pulla buffer from the sink. Restructure the sink to use
a queue like the source and only push a buffer when we can.
Improve SpaData. Offset and size should be between 0 and maxsize, make
sure we clamp correctly when needed.
node_process_output completes the processing of the output after
receiving HAVE_OUTPUT for async elements. It instructs the node that
it now can produce more output.
