2020-03-06Remove region-output export (GUI)Robin Gareus
This use-case is better served via stem-export. This export mode never worked correctly when latent plugins are present on the track. or when realtime export was chosen. This used to call track.export_stuff() -> bounce_process() periodically in small chunks from freewheeling callback, which is no longer functional.
2020-03-06Fix export alignment (#7916)Robin Gareus
Ardour's playback is aligned to master-out: "When the playback clock reads 01:00:00:00, the sample corresponding to 01:00:00:00 is audible at the speaker(s)" When exporting, and grabbing data from output ports, the signal is offset by the master-bus physical playback latency. This was compensated for, but lead to initial silence in the exported file. New approach is to start capturing export data during pre-roll, at the time when playback is written to the output buffers. To also shaves off a common offset to make this work with realtime export. Effectively this emulates processing with disconnected master-output port, while still keeping any latency of effects on the master-bus itself. Last but not least: jack updates latencies when freewheeling, (setting HW latency to zero). The callback arrives asynchronously some time after enabling freewheeling, but after Export Ports have been configured. Those callbacks are ignored.

2011-06-11Typedef all globally used export smart pointer types in one file.Sakari Bergen
Some of them need to be ordered in STL containers, and thus need a special comparable wrapper for boost::shared_ptr, defined in comparable_shared_ptr.h. This also alleviates the typedef hell present earlier in some export classes :) Making the timespan pointer comparable should fix bug #4093 git-svn-id: svn://localhost/ardour2/branches/3.0@9702 d708f5d6-7413-0410-9779-e7cbd77b26cf

2009-02-25*** NEW CODING POLICY ***David Robillard
All #include statements that include a header that is a part of a library bundled with ardour MUST use quotes, not angle brackets. Do this: #include "ardour/types.h" NOT this: #include <ardour/types.h> Rationale: This is best practice in general, to ensure we include the local version and not the system version. That quotes mean "local" (in some sense) and angle brackets mean "system" (in some sense) is a ubiquitous convention and IIRC right in the C spec somewhere. More pragmatically, this is required by (my) waf (stuff) for dependencies to work correctly. That is: !!! FAILURE TO DO THIS CAN RESULT IN BROKEN BUILDS !!! Failure to comply is punishable by death by torture. :) P.S. It's not that dramatic in all cases, but this (in combination with some GCC flags specific to the include type) is the best way I have found to be absolutely 100% positive the local ones are being used (and we definitely want to be absolutely 100% positive on that one). git-svn-id: svn://localhost/ardour2/branches/3.0@4655 d708f5d6-7413-0410-9779-e7cbd77b26cf
