<div dir="ltr">Thanks for the comments! I've updated the docs, changed latency_offset in pactl to a int64_t, and changed the corresponding calls to pa_atoi() to pa_atol().

two comments: (1) there is documentation that needs to be updated (man/<a href="http://pulse-cli-syntax.5.xml.in" rel="noreferrer" target="_blank">pulse-cli-syntax.5.xml.in</a>, man/<a href="http://pactl.1.xml.in" rel="noreferrer" target="_blank">pactl.1.xml.in</a>) (2) pactl still has latency_offset as a int32_t and uses pa_atoi(), pa_atoi() does not support int64_t; _set_port_latency_offset() should consistently use 64bit; I think this is a bug, int64_t should probably be used -- I suggest to do a precursory patch to fix this up <div class="HOEnZb"><div class="h5"> > On Wed, Jan 6, 2016 at 2:36 AM, Chris Billington <<a href="mailto:chrisjbillington@gmail.com">chrisjbillington@gmail.com</a> > > wrote: > > > This required the addition of two commands to the protocol: > > PA_COMMAND_SET_SINK_LATENCY_OFFSET and > > PA_COMMAND_SET_SOURCE_LATENCY_OFFSET. > > > > Changed integer type for the offset in pa_cli_command_port_offset() to > > int64_t. > > > > Bumped protocol version number to 31. > > --- > > PROTOCOL | 6 ++++ > > <a href="http://configure.ac" rel="noreferrer" target="_blank">configure.ac</a> | 2 +- > > src/map-file | 2 ++ > > src/pulse/introspect.c | 50 +++++++++++++++++++++++++++ > > src/pulse/introspect.h | 6 ++++ > > src/pulsecore/cli-command.c | 76 > > ++++++++++++++++++++++++++++++++++++++++- > > src/pulsecore/native-common.h | 4 +++ > > src/pulsecore/pdispatch.c | 4 +++ > > src/pulsecore/protocol-native.c | 75 > > ++++++++++++++++++++++++++++++++++++++++ > > src/utils/pacmd.c | 1 + > > src/utils/pactl.c | 39 +++++++++++++++++++++ > > 11 files changed, 263 insertions(+), 2 deletions(-) > > > > diff --git a/PROTOCOL b/PROTOCOL > > index 3c08fea..b6a5db7 100644 > > --- a/PROTOCOL > > +++ b/PROTOCOL > > @@ -371,6 +371,12 @@ PA_COMMAND_DISABLE_SRBCHANNEL > > Tells the client to stop listening on the additional SHM ringbuffer > > channel. > > Acked by client by sending PA_COMMAND_DISABLE_SRBCHANNEL back. > > > > +## v31, implemented by >= 8.0 > > +# > > +New opcodes: > > + PA_COMMAND_SET_SINK_LATENCY_OFFSET > > + PA_COMMAND_SET_SOURCE_LATENCY_OFFSET > > + > > #### If you just changed the protocol, read this > > ## module-tunnel depends on the sink/source/sink-input/source-input > > protocol > > ## internals, so if you changed these, you might have broken > > module-tunnel. > > diff --git a/<a href="http://configure.ac" rel="noreferrer" target="_blank">configure.ac</a> b/<a href="http://configure.ac" rel="noreferrer" target="_blank">configure.ac</a> > > index ee1b437..e749024 100644 > > --- a/<a href="http://configure.ac" rel="noreferrer" target="_blank">configure.ac</a> > > +++ b/<a href="http://configure.ac" rel="noreferrer" target="_blank">configure.ac</a> > > @@ -40,7 +40,7 @@ AC_SUBST(PA_MINOR, pa_minor) > > AC_SUBST(PA_MAJORMINOR, pa_major.pa_minor) > > > > AC_SUBST(PA_API_VERSION, 12) > > -AC_SUBST(PA_PROTOCOL_VERSION, 30) > > +AC_SUBST(PA_PROTOCOL_VERSION, 31) > > > > # The stable ABI for client applications, for the version info x:y:z > > # always will hold y=z > > diff --git a/src/map-file b/src/map-file > > index 93a62b8..7826fa4 100644 > > --- a/src/map-file > > +++ b/src/map-file > > @@ -62,6 +62,8 @@ pa_context_get_source_info_list;
