2020-03-06Fix potential deadlock when exporting w/normalizingRobin Gareus
start_post_processing() may be called from the freewheeling callback, when starting to normalize.
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.

2019-04-08NO-OP: whitespaceRobin Gareus
Fix space-alignment, mostly due to "frame" -> "sample" changes.
2018-11-19Initial backend support for external export encoderRobin Gareus
This adds an experimental pipe to ffmpeg to encode mp3. Currently quality is hardcoded and various aspects remain to be implemented. However, it is sufficient for initial testing.

2016-07-18No-Op: rename Normalizer to IntermediateRobin Gareus
post-processing is no longer just Normalization. RealtimeExport does Encoding - faster than realtime - using the same infrastructure.
2016-07-16libardour support for timespan realtime exportRobin Gareus
2016-07-16Refactor TmpFile into an abstract base classRobin Gareus
This allows a TmpFile pointer to be either a Sync or Async (Threaded) writer. As result we must be able to handle both RT and non RT processing. Still, post-processing (normalization and encoding) should always happen faster than realtime (freewheeling). Since jack does not allow a client to change to freewheeling from within the process-callback, the async-writer disk-thread FileFlushed is used to initiate post-processing.
2016-07-14refactoring to prepare for real-time exportRobin Gareus
* add a threaded TmpFile Writer * update API calls to that process_export_fw() can be used as process_function The idea is to re-use export infrastructure from normalization: export to a tmp-file and then encode target formats after that.

2012-05-24Remove over 500 unnecessary includes (including 54 of session.h).David Robillard
It's slightly possible that this causes trivial build failures on different configurations, but otherwise shouldn't cause any problems (i.e. no actual changes other than include/naming/namespace stuff). I deliberately avoided removing libardour-config.h since this can mysteriously break things, though a few of those do seem to be unnecessary. This commit only targets includes of ardour/*.h. There is also a very large number of unnecessary includes of stuff in gtk2_ardour; tackling that should also give a big improvement in build time when things are modified. git-svn-id: svn://localhost/ardour2/branches/3.0@12420 d708f5d6-7413-0410-9779-e7cbd77b26cf

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
