Re: [pulseaudio-discuss] How to capture one of multiple radios that these radios play at the same time?

Thank you for your help.
I refer to source code of pavucontrol and I program a simple code below:
Ultimately what your code is doing is thus:
1. Get the Sink Index the stream is using.
2. Get the Monitor Source for the Sink.
3. Record from the Monitor of the Sink.
The sink monitor will contain the product of *all* streams playing on
the sink. There is a special Sink Input Monitor that you can connect
to for your recording. It's will just contain the sound for the Sink
Input itself. You still need to get the Monitor for the sink to which
your stream is attached, but you pass this in to the
pa_stream_connect_record function as a string.
In pavucontrol's mainwindow.cc see the method:
MainWindow::createMonitorStreamForSinkInput()
int sink_input_index = ?; /* You should have this value already in your
code */
int sink_monitor_source_index = ?; /* You should have this value already
in your code */
char dev[16];
pa_stream *stream;
/* assume variable ss is your sample spec and attr is your buffer
attributes */
if (!(stream = pa_stream_new(context, _(Single Radio Snooper!), ss,
NULL))) {
/* ERROR */
return;
}
/* Put the source which we'll record here (i.e. the montior of the sink
the stream is playing on) */
dev = snprintf(dev, sizeof(dev), %u, sink_monitor_source_index);
/* restrict the recording to just one monitor stream */
pa_stream_set_monitor_stream(stream, sink_input_index);
/* Set callbacks */
pa_stream_set_read_callback(stream, );
pa_stream_set_suspended_callback(stream, );
if (pa_stream_connect_record(stream, dev, attr, (pa_stream_flags_t)
(PA_STREAM_DONT_MOVE|PA_STREAM_ADJUST_LATENCY)) 0) {
/* ERROR */
pa_stream_unref(stream);
stream = NULL;
return;
}
Obviously if the user moves your stream to another device you have to
tear down and recreate your stream against the new monitor source. Not
ideal, but should be fine in most circumstances. Sadly there isn't a way
to record the radio fully across device moves as far as I know...
although perhaps not setting the PA_STREAM_DONT_MOVE flag will allow the
record stream to automatically move if the stream is moved? I don't know...

Re: [pulseaudio-discuss] How to capture one of multiple radios that these radios play at the same time?
Thank you for your answers.
But I can't still realize how to create a Sink Input Monitor?
I also use pa_stream_set_monitor_stream method in my code before,
but it still records all streams playing on the sink.
I want to create a Sink Input Monitor; however,it seems that I
create Sink Monitor.
I want to record only one audio form a unique sink input, but I record
all audios from whole sink.
Can you teach me how to create a Sink Input Monitor to record a
single audio in one sink input again?
Maybe I am silly so that I can't realize your answer before.
Thank you very much.

For clarity, the code below is NOT from the above function. I meant to
include some text saying so you could write something like this: here :)
int sink_input_index = ?; /* You should have this value already in your
code */
int sink_monitor_source_index = ?; /* You should have this value already
in your code */
char dev[16];

You appear to be using the sink_input_index value before you even run
the main loop... This value will just contain the default values and
thus I suspect they all have 0's which ultimately maps to the default
monitor source and no specific sink input.
You need to run the main loop and let all the necessary call backs be
called and get all the necessary index values before you actually use them.

You need to run the main loop and let all the necessary call backs be called and get all the necessary index values before you actually use them. The program does run the mainloop, using pa_mainloop_iterate in a few places. And sink_input_index is given on the command line anyway, not queried from anywhere. To me it looks like the program is pretty correct. I can verify that it really records the mixed audio, though. I wonder if the separate stream monitoring feature has broken at some point - I think it's not widely used. -- Tanu ___ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss

I observe sink input indexs in PulseAudio Manager: Sink input indexs have no change when I run my code. But Source output appears each time,and the index of source outputs ~~~ are increment. ~~ =There is only one source output index at the same time. I can't find monitor source index in PulseAudio Panel. You need to run the main loop and let all the necessary call backs be called and get all the necessary index values before you actually use them. So,do you want to tell me monitor source index is decided after running main loop and all necessary callbacks?
