Make a method to find the memory block for the given ptr. We can
use this to find the memfd of the memory if there is any. We can
then remove the Shared metadata on buffers.
When the input port param enumeration has no result, use the NULL
filter to still enumerate the output port parameters instead of
returning nothing.
Fix the offset in the gst element.
Add control properties to audiotestsrc for frequency and volume
and add a test program.
Add size parameter to set_io for additional checks and to make it
easy to know how much control data we can write.
Make it possible to configure multiple io areas on a port by giving
an id to set_io.
Add some types to enumerate the supported ids
Make an area to exchange buffers and one to specify pull ranges.
The idea is to make more area types for controlable properties.
Implement enumeration of IO areas in volume.
We can't use a ringbuffer on the chunk because it implies the
consumer would write to it to update the read position, which we
can't do because the chunk is read-only and might even be shared.
Go back to offset/size pairs, which can sortof do the same thing
if we want later when we keep a non-shared read pointer in the
consumer.
Keep alsa timestamp around and filled state for future.
mmap the input port meta/data/chunk as read-only.
Only do clock update requests when asked.
We can't allocate the shared meta in shared mem because then clients can
damage it for other clients. Place it instead right after the buffer
metadata array. Filter out the shared metadata for a client, we send it
as part of the client_buffer structure.
Remove pointer metadata, it's not so useful.
Document the layout of the allocated buffers and the shared memory.
Work on metadata to define control parameters
ringbuffer: remove size and mask from the ringbuffer, we have that
elsewhere in the user of the ringbuffer.
Remove the buffer data offset and size fields and replace with a
ringbuffer. We then have a ringbuffer in all buffer data, which
simplifies things.
We can now remove the ringbuffer metadata.
Reset the builder when the filter failed.
Make the plugins create their params in a temporary buffer, we
don't want to do in-place filtering because that is not always
possible. Because the filter now resets on error, we can remove
the reset from the plugins.
Add an argument to pass the result param to the caller instead of
having the caller have to pick it up from the builder.
Improve docs for node, clock and monitor
Pass spa_pod everywhere instead of spa_pod_object.
Pass result argument to spa_pod_filter to make things a little
nicer.
Remove the frame argument from the builder, we can use the builder
allocated frames.
Add deref function to builder to make it more flexible later.
Add some more recursion depth checks in the parser.
Improve props filter, also filter other types.
Make enum_params and set_param to configure properties, format
and other parameters. This allows us to remove some duplicate
code and make the properties and parameters much more extensible.
Use the object id to mark the id of the parameter.
Remove the spa_format and spa_props.
We can now make the client-node easier by merging the various
format methods into the params.
Make the stream API more powerful now that we can pass params
around.
Fix ringbuffer mixing in audiomixer
Add ringbuffer support in audiotestsrc params
Don't recycle buffers before signaling have_output, the app is supposed
to recycle explicitly or with a process_output call.
Add some trace to graph functions in tests
Add ringbuffer support in export-source
Only send data to a client when it has sent a NEED_INPUT otherwise
recycle the buffers immediately.
Explicitly recycle buffers when the client is not going to do this.
When recycle_buffer() is called while in the new_buffer event handler,
don't send the reuse_buffer event. Instead, mark the buffer for
recycling by putting the buffer ID in the IO area, which is more
light-weight. When need_input reaches the server, it will recycle the
buffer.
Also introduce a helper function for sending the reuse_buffer event.
Change-Id: I900e75694efce2fa7e12840eaf53a7f6b7ae7e8a
Emit the new_buffer event only if the IO area status is HAVE_BUFFER.
In client-reuse mode, also clear the buffer ID - we need an explicit
recycle call before recycling.
Change-Id: I139663068ef12669adc13b7e351666c8469dee72
We can initialize the transport as soon as we get async notify
from the client when setup completes. Node initialization happens
after that and then finaly the node is initialized and we can send
the transport and fds.
Small cleanups
