From 47b8fa21699e58f733f0ecb879193092f93c93d8 Mon Sep 17 00:00:00 2001 From: Carl Hetherington Date: Wed, 25 Nov 2009 23:29:52 +0000 Subject: Give Processor::run a new parameter to say whether or not the run method must leave the passed-in buffers valid. In the case where the main outs delivery is the last processor in a route, this is not necessary (and wasteful). If another processor (e.g. a meter) follows the main outs, the passed-in (scratch) buffers must be valid or the meter will get garbage data. Fixes meters displaying phantom signals in some cases. git-svn-id: svn://localhost/ardour2/branches/3.0@6180 d708f5d6-7413-0410-9779-e7cbd77b26cf --- libs/ardour/port_insert.cc | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'libs/ardour/port_insert.cc') diff --git a/libs/ardour/port_insert.cc b/libs/ardour/port_insert.cc index 3b02bf41da..4df27bff72 100644 --- a/libs/ardour/port_insert.cc +++ b/libs/ardour/port_insert.cc @@ -66,7 +66,7 @@ PortInsert::~PortInsert () } void -PortInsert::run (BufferSet& bufs, sframes_t start_frame, sframes_t end_frame, nframes_t nframes) +PortInsert::run (BufferSet& bufs, sframes_t start_frame, sframes_t end_frame, nframes_t nframes, bool) { if (_output->n_ports().n_total() == 0) { return; @@ -78,7 +78,7 @@ PortInsert::run (BufferSet& bufs, sframes_t start_frame, sframes_t end_frame, nf goto out; } - _out->run (bufs, start_frame, end_frame, nframes); + _out->run (bufs, start_frame, end_frame, nframes, true); _input->collect_input (bufs, nframes, ChanCount::ZERO); out: -- cgit v1.2.3
