Work on idle poll
Move node state to the node interface so that we can actually get it in
the sync case.
Add enabled field to the poll event
Work on audiotestsrc
Remove the port object. We don't use it as a dbus object and we don't
need it, we can use the link and node object directy.
Move poll code and event handler to the node.
Support to parse configuration files. By default, the default conf file
is parsed ({sysconfdir}/pinos/pinos.conf), but that can be changed with
an environment variable (PINOS_CONFIG_FILE). The file can contain
commands and assignments (no assignment supported this far).
Support for command module-load is added.
Make a new USE_BUFFERS command to atomically send a buffer array to the
remote client. We can use this to then clean up an old array and go to
the PAUSED state if possible.
Work on formats. Make one structure that can hold all video formats.
Work on pipeline suspend and resume.
Add jpeg support to v4l2.
Work on enum_formats with a filter in v4l2.
Remove old code
Only depend on GStreamer for the plugins
Rename STOP to PAUSE because that's what it really does
Start working on format_fixate.
Remove default property value from props
Fix framerate
Remove _remove from properties, we can do the same with set of a NULL
value.
Add signals to the stream API to manage the buffers. Wrap those buffers
in a GstBuffer in the pinossrc and pinossink elements and pool them in a
bufferpool.
Remove SPA_EVENT_TYPE_PULL_INPUT, we can do the same with NEED_INPUT and
by using a ringbuffer.
Do more complete allocation of buffers in the link. Use the buffer
allocator if none of the nodes can allocate.
Follow the node state to trigger negotiation and allocation.
Remove offset and size when refering to buffers, we want to always deal
with the complete buffer and use a ringbuffer for ranges or change the
offset/size in the buffer data when needed.
Serialize port_info structures as part of the port_update
Print both the enum number and the name when debuging properties or
formats.
Remove the hardcoded negotiation and replace by filtering accepted and
possible formats. Not quite correct yet because v4l2 doesn't actually do
filtering yet.
Serialize format and properties.
Simplify the properties by moving the unset-mask inside the property
structure. We can then also just use the index of the property as the
bit in the mask.
Work on stopping on disconnect
Implements the basics of the PORT_UPDATE control message
Add the ports to the proxy node with whe PORT_UPDATE control message.
Let the proxy node check the events and create dbus objects based on
added/removed ports.
Add helpers to convert between pinos and gstreamer formats.
Use pinos formats in the API.
Work on removing some hardcoded stuff and instead use the real format
from the pinos server.
Use memfd and sealing.
Add a memory reference helper struct that we can use to track the memory
in buffers and formats.
Remove custom property get and set, the default ones will work fine.
Custom ones are problematic when we want to serialize properties in
formats etc.
Deserialized Formats are now tracked in the memory pool and can be freed
if needed.
Make buffer data point to a registered memory block by its mem_id.
Add some more helpers to allocate memfd backed memory.
Allocate buffers in memfd so that we easily share them between client
and server.
Update pts and seq in v4l2 now that this change will actually be visible
at the client.
Use stucture offsets instead of pointers so that we can share the buffer
structure between client and server.
We can then pass an fd wrapping the memory of the buffer to the client.
Add beginnings of a memory pool
Rework things so that we negotiate buffer pools beforehand and only pass
buffer ids around We can then remove the refcount of buffers, events and
commands.
More work on buffer reuse
Use the node state changes to trigger the next step in the configuration
sequence.
Move most of the client-node to a plugin
Do buffer allocation in the port link.
We now only allow per port preallocated buffers. We exchange the index
into the array instead of passing the buffers around. We still use the
refcount to track when a buffer can be reused.
Improve API a little, allow passing the node as the first argument of
the interface call.
Implement alloc_buffer in v4l2 and improve the test.
Remove the old PinosBuffer object and replace it with SpaControl, this
communication protocol is designed to make it possible to implement
remote nodes and so it is moved to Spa.
Move SpaBuffer into to API
Work on easier API to make formats, implement enumeration and support
for all formats in v4l2.
Improve format output in -inspect
Keep state variable to enumerate things. This allows us to remove the
expectation that the same index will give the same item.
Use a new rectangle type for video size. When enumerating sizes, this
allows us to specify relations between width and height more easily.
Remove the struct and bytes type, they are like pointer.
Add filter to enum_formats to speed up enumerations.
Add generic pointer metadata type that is copied on import
Pass array of pointers to SpaBuffers in use_buffers.
Make sure we use the same data and metadata as the imported buffer.
Remove the thread from alsa sink and use the pollfd event.
Make it possible to pass multiple fds in one pollfd event
Add 3 callbacks to the pollfd event and add support for timeouts
