Make sure we clear IO_Buffers on the port and mixer before we clear the
buffers or the format. The IO_Buffer is used to check if the port should
be processed or not and its update is synchronized with the data-thread.
Set IO_Buffers on the mixer and node only after we have configured the
buffers on the node.
See #4094
We simply cannot schedule async nodes properly if we don't have the
async link. This change was done to make sure that driver sources don't
end up with async buffers and cause a unneccesary 1 cycle delay in
async clients. But we can fix this in a better way, like this:
Increment the cycle counter after we copy the output port buffers. This
ensures the async clients immediately pick up the new buffers (or the
output buffers from the previous cycle).
Also remove some old compatibility code that is no longer useful.
Fixes#4138
See #4133
Unloading the module on stream errors is a bit too much because a
suspend can clear the stream error again (or the error might not be
fatal)
This can happen for example when negotiation fails on some stream ports
(wireplumber tries to link the midi ports to audio ports) and it's
better to not completely fail on that.
Fixes#4121
A remote node is prepared when the Start command sync reply has been
received.
If we however quickly switch from active to inactive, the
pending reply is cancelled but the remote node will have set the
FINISHED status and will be ready to be scheduled.
Make it so that we always set the INACTIVE status when the node is
canceled and unprepared, even if we didn't get the reply and the node
was not prepared.
Fixes#4122
dlopen() does not set errno on failure, rather you're supposed to call
dlerror() to get the latest error. dlerror() return a string so
instead return -ENOENT from weakjack_load_by_path().
Depending on errno weakjack_load() could think it successfully loaded
the library, and later module-jack-tunnel would crash because it call
a NULL function pointer.
Make a new flag that is set when the process function is called because
of a recover from a graph xrun.
Use this flag in the freewheel driver to detect a recover and to avoid
scheduling a new timeout. We should schedule a new timeout only when the
process function was called after completion.
This fixes export in ardour some more when the initial driver timeout
didn't complete (when, for example, some nodes were still starting up).
When spa-plugins is enabled, the gio-2.0 global dependency is
overwritten.
When bluez support is enabled, OR when gsettings is enabled, the gio-2.0
dependency is then detected as found. This means that
pipewire-module-protocol-pulse can end up enabling gsettings support
even if it has been forcibly turned off.
Rename the meson variables to ensure they are looked up separately.
Make a property to pass a custom function pointer to create threads
instead of pthread_create.
Use this in jack instead of bypassing the thread utils create function,
which gives the wrong thread rt priority with rtkit.
Fixes#4099
Move the address:port parsing code to the net helper. Add a default
address option.
Pass the interface address to protocol-simple and use this as the
default address for listening.
This makes sure that when the user passes tcp:3400 that we don't end up
publishing 0.0.0.0:3400 but the actual address of the interface we are
listening on so that the snapcast discover can use this to notify the
snapcast server.
Fixes#4093
When a stream is stopped, chances are high that downstream elements
change or get reset, i.e. don't remember a previously send rotation
event. Thus reset the transform value in order to ensure we create a new
one on the next stream start.
In order to not regress the case when downstream *does* remember the
orientation and the buffer orientation changes from e.g.
`TRANSFORMATION_90` to `TRANSFORMATION_None` between stream
stop and restart, initialize the remembered transform to an invalid
value and ensure we always send a rotation event, even for
`TRANSFORMATION_None`.
`pw_stream_destroy()` chains up to `on_remove_buffer()` in
GstPipeWireSrc which again needs the stream to still be around to call
`pw_stream_queue_buffer()` on it. By using `g_clear_pointer()` it will
already have been cleared, causing crashes.
Revert to the behavior from before the commit mentioned below and add a
comment in order to avoid regressing in a future cleanup.
Fixes: 0c40c0147 (gst: factor out the stream management and some common variables in a new class)
Don't wait for the client to set the INACTIVE state, do it on the
server. We already decremented the target required so we don't want to
schedule the node anymore.
Fixes some xruns when removing nodes in a stress test.
Make it so that a driver node can never be scheduled async. It could
possibly make sense when the driver node is not currently driving the
graph but when it drives the graph it always needs to be sync. This
also simplifies the target activation because we can simply check the
async state and ignore if the node is driving or not.
Also make sure that we never make an async link with a driver output port.
This does not make sense because the driver node will always be
triggered sync first and before the async node so we can simply make
a sync link.
This fixes the modified (only generate 1 buffer) video-src -> video-play
case where the buffer never arrives in video-play because of the
useless async link.
Fixes#4092
Keep track of the sync nodes we added to a driver and bring in the other
nodes from the same sync group, group or link groups. This makes it
possible to have disjoint sync groups each with their own driver.
Fixes export in ardour8
Fixes#4083
When the node activation.required was incremented because it was a
driver, only decrement it in that case, regardless of the current driver
state of the node.
This fixes the case of KODI where the required field gets out of sync
and things become unschedulable.
Fixes#4087
A driver can't be async, we always need to be able to trigger it
to start it so increment the required field.
Fixes an issue with asunc drivers such as the video-src example or gnome
screen sharing.
32 bits are enough, and additionally this also fixes an incorrect
format string, which caused the default `audio.rate` to be
incorrectly set on some platforms, such as 32-bit arm ones.
Fixes#4080
Can be used to group ports together. Mostly because they are all from
the same stream and split into multiple ports by audioconvert/adapter.
Also useful for the alsa sequence to group client ports together.
Also interesting when pw-filter would be able to handle streams in the
future to find out what ports belong to what streams.
This prints changed state, props and params when run with -m and running
the `info` command. We try to print only things that have changed. It
would probably be good to make the props (and params) print a diff of
what's changed as well.
If the sender is reset, the RTP stream may return, but may no longer
correspond to the stream for which we loaded this instance of
module-rtp-source. A power cycle or network reset on Dante devices
causes a new SDP and SSRC to be selected, for example.
So let's make sure we don't consider invalid receives while tracking our
"receiving" state. Arguable, we should bail entirely if this happens.
PipeWire expects the SPA_TYPE_OBJECT_ParamBuffers to be valid after
setting SPA_PARAM_Format. The pipewiresink knows the final buffer size
only after the pipewirepool has been activated.
There is a race between PipeWire asking the pipewiresink for the buffers
and GStreamer activating the buffer pool. If GStreamer has not activated
the buffer pool before PipeWire asks for the Buffer params, PipeWire
won't allocate buffers with the correct type and size.
The chance of hitting this window increases, if the upstream GStreamer
element doesn't use the buffer pool. In this case the buffer pool is
activated by the first buffer that arrives at the pipewiresink, which
may take some time.
Instead of not updating the Buffer params when the buffer pool is not
active, wait for the buffer pool to become active.
Add a helper function for updating the params instead of handling it in
the pool_activated callback. This allows to explicitly set the params
from the element.
roc-toolkit commit 03d29eb97211ca87593566998c5087590c1bae38 [0]
("Add sample_format() and pcm_format() to SampleSpec") made
a change in how the packet encoding is determined. Specifically:
This commit introduces small breaking change in C API:
when we search for packet_encoding compatible with
frame_encoding, we now take into account format too.
It means that if you use ROC_FORMAT_PCM_FLOAT32 in frame_encoding,
ROC_PACKET_ENCODING_AVP_L16_STEREO will not be selected automatically
anymore, and you need to specify it manually via packet_encoding.
This causes module-roc-sink to fail to set up the ROC sender:
roc_api: bad configuration: failed to select packet_encoding matching frame_encoding, set roc_sender_config.packet_encoding manually
So specify `ROC_PACKET_ENCODING_AVP_L16_STEREO` explicitly
as the packet encoding. This seems to work with roc-toolkit 0.3,
so the required version is not changed.
Fixes#4070

It's not used anymore because it does work so well.
The problem is that while it transparently proxies param enums on
ports to peers, it fails to emit events when those peer
params change in a way that would make the enum result change as well.
This makes it quite hard to use this correctly.
Print the state of the stream not only as the numeric value, but also
print the name of the state to help the reader.
While at it, add the sink element to the log output to be able to
identify the sink that received the state change.
There isn't a good way to surface this information to the module owner
yet, so let's publish the information on the stream so we can try to
manage things in policy.
This is the driver id that the client has received and is using right
now. We don't use this yet but it could be used in the future to check
if a client has the most up to date info.
The pipewiresrc starts the stream in active state but should be inactive
if only going to PAUSED state. This patch sets the stream to inactive
when wait_started has returned in the GStreamer state tranistions.
Also resets internal started state when going PAUSED -> READY.
Fixes#4049
Make sure newer clients can work with an older server:
- Add client and server versions in the activation
- On older server, clients needs to trigger peers without CAS of status
- On older server, jack transport is started with command.
- Use client version to know when to set the INACTIVE/FINISHED
state on the server instead.
- Async clients need to trigger peers on old server.
Also handle the relation between a node and the driver with pw_node_peer,
like we do with the links.
Because these are refcounted, we only make one peer for a node that is
linked to another node that is also the driver (pw-play -> sink) and we
save some fds as well as some admin stuff and overhead for the refcounts.
This in return then results in less problems getting all the refcounts
right when adding/removing nodes.
