There is no need to encode the potential format in the format.dsp of
control ports, this is just for legacy compatibility with JACK apps. The
actual format can be negotiated with the types field.
Fixes midi port visibility with apps compiled against 1.2, such as JACK
apps in flatpaks.
Only react to the capture stream state change and format changes. The
playback and capture streams change state somewhat concurrently and so
the graph state might not be consistent.
Because only the capture stream will trigger the playback stream and
start the processing, we can safely react to capture stream changes
only.
The params contain the send/recv streams from the point of view of the
manager (and not the driver as was assumed before). This means we need
to swap send/recv in the driver, not the manager.
This makes things interoperate with JACK/netjack2.
See #4666
Sometimes you want to use the convolver as a delay without adding
latency so add a latency option to tweak the automatic latency
reporting. Use this in the upmix rear delay filters.
Collect the latency of the graph in filter-chain. We do this by first
inspecting the LATENCY ports on the plugins and us the notify value as
the latency on the node.
We then walk the graph from source to sink and for each node take the
max latency of all linked upstream peer nodes. We end up with the max
latency of the graph and emit this in the graph properties.
We then listen for the graph latency property and use that to update the
process_latency of the filter-chain, which will then update the latency
on the filter-chain ports.
Fixes#4678
Destroy the sources from the io handler immediately when there is an
error so that we don't end up in endless error wakeups.
Schedule the free from the main loop and make sure only one can ever
run.
The manager is actually not supposed to decide much about the number of
audio and midi ports. It should just suggest a default when connecting
driver doesn't know.
Add a audio.ports parameters to manager and driver to suggest/ask for
the amount of audio ports. Let the audio.position/audio.channels be a
specification of the channel mask in case it matches the requested
channels, otherwise use AUX channels for the ports.
This means that we must derive the mode (sink/source/audio/midi) from
the ports that are negotiated in the manager and the driver, so delay
this until after negotiation.
Make sure all the possible modes work. For midi only streams, we can't
wait for the session manager to perform a PortConfig so do that
ourselves. Make sure we only use a source trigger when we have a sink.
Fixes#4666
Keep a position info for the stream it was set and then use the position
info for the stream that is driving the graph. Otherwise we might use a
destroyed position info.
Add support for FairPlay SAP v2.5 (encryption type 5) type devices such as Apple Home Pod Minis.
Apparently only these devices require the `POST /feedback` heartbeat, so fix that.
Initialize the byte array with bytes instead of a string because the 0
byte at the end of the string does not fit in the array and causes a
compiler warning.
The midi events have their large data offsets relative to the start of
the buffer and the large data is at the end of the buffer. Because we
copied it down, right after the events, but we didn't adjust the
offsets, calculate a correction offset when unpacking the events.
SysEx in UMP can span multiple packets. In MIDI1 we can't split them up
into multiple events so we need to collect the complete sysex and then
write out the event.
Fixes SysEx writes to ALSA seq by running the event encoder until a
valid packet is completed.
Also fixes split MIDI1 packets in the JACK API when going through the
tunnel or via netjack.
Add jack.connect-audio and jack.connect-midi to specify an array of port
names to link to instead of the default phyisical ports.
Also actually fixes linking the midi ports correctly.
Make the state_changed event and _get_state() function set errno with
the current error value if the state is in error, so that application
can use this to give more detailed error reporting.
Use this in alsa, v4l2 and pulse to give some other error codes than
EIO.
Fixes#4574
Some of the more common errors (caused by packet loss, network jitter, ...)
should be reported with INFO unless there is some indication about how
to fix the problem.
Fixes#4559
