When toggling a channel-configs the following happens:
1. TrackExportChannelSelector::update_config
2. ExportProfileManager::clear_channel_configs
3. RouteExportChannel::create_from_route
[...] CriticalSelectionChanged
4. ExportDialog::update_warnings_and_example_filename
5. ARDOUR::ExportProfileManager::get_warnings
6. ARDOUR::ExportProfileManager::build_filenames
7. ARDOUR::ExportFilename::set_channel_config
[...]
Step 3 creates a RouteExportChannel, Step 7 retains a
shared-pointer to it in the config's ExportFilenamePtr.
When toggling another channel: step 2 release the reference
and step 3 creates a new RouteExportChannel.
This new channel reuses the existing Route::_capture_processor (!).
Now Step 7 releases the first RouteExportChannel in order
to get_warnings for the new one. Since ExportFilenamePtr holds the
the last reference, the d'tor of RouteExportChannel runs,
which removes the capture-processor from the route.
The newly created RouteExportChannel now has a reference
to a CaptureProcessor that is not in the signal-flow.
Note: the order of adding/removing RouteExportChannel matters.
With a two track session:
* Disable "with track/bus processing
* Enable Track 1
* Enable Track 2
* Disable Track 1
* Enable Track 1 // << Track 2 becomes silent
When a control-point is exactly at tick (N * 8), iterating
over the List (Sequence<Time>::const_iterator::operator++)
skipped the point.
Sequence::time_between_interpolated_controller_outputs == 8.
This reverts commit 37cae2f971.
This changes causes issues with recursive calls to the enter/leave event handling
stacks in gtk2_adour. Semantically, the change makes perfect sense, but finding
a solution to the recursion is challenging.
This is better provided by Plugin::print_parameter, which
is called by PluginControl::get_user_string(). This removes
special cases for the mode enums.
Disambiguate export formats with different encoder
qualities, sample-formats or settings (wav/bwav).
This allows to export multipe mp3 with different bitrates.
When multiple child processes are running, closing the
stdin of one child did not send EOF or cause POLLNVAL,
as long as a dup()'ed filedes still existed.
This fixes an issue when running an mp3 encoder while the
video monitor is visible, and will allow to concurrently
run multiple mp3 encoders or other child processes.
Previously this caused Ardour to hang indefinitely in CmdPipeWriter
```
_proc->close_stdin();
_proc->wait(); // << here
```
