Now using a globally-scoped static variable which is updated by the
AudioEngine whenever an SR change occurs. Defaults to 48kHz and can
be used even before there is a backend.
* cleaner table layout
* explicit options for bouncing to Trigger and Clip List
* any bounce is added to Source list, so remove that from menu
* format context menus to match "(with processing)"
* use same code structure where possible
Due to recent changes, when the master bus is disconnected its
private port latency was never unset. This lead to misalignment
when using stem-export if master (or monitor) output was not
connected.
This will eventually have to be fixed, currently split-channel
files are not correctly tagged and post process commands
are only emitted for the last file.
But fixing this is complicated, so meanwhile a workaround is used.
Eventually this commit should be [mostly] reverted!
When a track's output is not connected, we assume
its output playback latency matches that of the master-bus.
This is to prevent the track's output latency to float
freely (see also a556e96ed0).
This failed if a track is connected to another track which is
not connected.
On Intel systems ArdourCanvas::COORD_MAX (1.7e+307) was rounded
to (gint) -2147483648. gtk+ treats negative window size-requests
as 1px.
However on ARM, COORD_MAX was truncated to +2147483648, gtk+ limits
this to 65535. Most WM/Xwin systems cannot handle windows this large.
It also exceeds the max size of cairo [image] surfaces.
This issue was introduced in a1c67b4ad7
when "natural_size" was removed. Before that change infinitely large
canvas had a natural_size of 2x2 px.
Previously every region fragment was added one at a time,
with each emitting signals and updating the GUI. If there are a
few thousand regions Ardour can freeze for a significant amount
of time.
There is still the issue that the GUI freezes after the progress-bar
reached the end: consolidate overlapping ranges after analysis, then
add regions.
And Playlist::flush_notifications still emits
RegionFactory::CheckNewRegion() for every region individually
and RegionListBase::add_region becomes the bottleneck.
But at least adding 7k regions now returns in under 5 minutes
instead of taking over an hour.
This fixes an issue with the videotimeline not being shown
when reloading a session. Editor::set_state() restores the grid,
which in turn changes ruler visibility. This triggers
store_ruler_visibility() and the saved session state was lost.
This fixes an issue when loading sessions in "safe mode".
Internal side-chain sends are removed if the target port
does not exist. Also other port connections are lost if the
target port does not exist.
Since cc6c0f1263 there is no Properties::position event
when a region is moved. So notify_region_moved() or
notify_region_start_trimmed() was never emitted and
Session::maybe_update_session_range() was not called.
When a track's output is not connected, but the track feeds
other tracks via sends (common case in Mixbus) the stem
export of the track was not correctly aligned.
The track is correctly latency compensated (due to sends), but
the unconnected port's latency is not set.
However stem-export uses the private latency of the port as alignment.
* audio files can be named "0bpm" to make them un-stretchable
* however they still need a sensible beatcnt, and therefore tempo
* assume tempo 120bpm and assign a beatcnt based on the file's length
* the user might later enable stretch, and we need to be sensible about it
