Remove the memory stuff from the spa API, we can do thing more simple
and efficiently if we always allocate buffers outside of the plugins and
only implement an alloc function on the node when it can do something
clever.
Move serialize code to the props/format/buffer code
Make it possible to copy a format and properties.
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.
A module is a shared library existing in, or a subdirectory of, the
module directory. The directory is by default
${libdir}/pinos-$(MAJORMINOR)/modules, but can be specified with
--with-module-dir=PATH when running configure. It is also possible to
override the module directory runtime with the environment variable
PINOS_MODULE_DIR, which is a list of directories separated with ":".
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
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.
The GstNodeFactory creates GstSource nodes without ports. When an
output port is created later, the proper GStreamer element will be
created in the node.
main.c registers a GstNodeFactory in the daemon, so clients can use it
in calls to CreateNode and CreatePort.
