Make explicit links between elements that are used to activate the
next element in the graph.
Make subgraphs a special regular node. Make a link from the
subgraph children to the parent so that the subgraph completes when
all the children completed.
Implement a single process function in plugins
Remove many messages in the client node
Move the activation state to the graph
Replace an old scheduler with a new one that works with the new
activation states.
Remove the DISABLED port flags, we explicitly add and remove to
make ports enabled/disabled.
Find first compatible port for link
Remove the node based scheduler and use the spa one.
A device that supports continuous/step-wise frame interval will
report the correct frame intervals for index 0 and EINVAL for
every other index.
(https://linuxtv.org/downloads/v4l-dvb-apis/uapi/v4l/vidioc-enum-frameintervals.html)
Previously, the code would exit from the loop after successfully
reading index 0, without marking that the iteration of frame
interval completed. Therefore, the next time the function was
called the same frame intervals would be read, instead of advancing
to the next frame size or format type.
Instead, mark that we need to try and read the next format size.
Fixes#56
Clang++ (and g++) don't define __STDC_VERSION__ which results in
include/spa/support/log.h:101:5: error: '__STDC_VERSION__' is not defined, evaluates to 0 [-Werror,-Wundef]
#if __STDC_VERSION__ >= 199901L
include/pipewire/log.h:64:5: error: '__STDC_VERSION__' is not defined, evaluates to 0 [-Werror,-Wundef]
#if __STDC_VERSION__ >= 199901L
so check if __STDC_VERSION__ is defined before comparing.
Also, include/feature.h additionally defines __USE_ISOC99 (and
__USE_ISOC11 for C11 extension), so check these as well.
Don't use a destroy_list anymore, it's not safe anyway. Instead require
that sources be removed with (a blocking) invoke. Make sure we don't
dispatch sources that were removed from the loop.
Add the right propId to properties so they can get controls.
Keep track of properties and handle the io area for them
Check if properties changed and update the v4l2 controls
When the mixer has no bytes queued, only ask for more bytes when
we were in the OK status otherwise we might override the HAVE_BUFFER
status and discard the queued buffer.
Pass client to some core functions to make it possible to check
permissions when iterating globals.
Check permissions of factory before using it.
Check permissions in link factory, only allow linking of nodes we can
see.
Check permissions in the autolink module, only try to link to nodes
we can see.
Make client permissions update behave like an atomic update of an
unordered set of permissions, which is perhaps a bit more intuitive.
Don't unlink the ports of an inactive link because then it might be
possible that the scheduler can't recycle a buffer, instead use
a port flag to mark the ports disabled and change to scheduler to
skip those ports.
