Asked by Andrey on 2017-07-16

I'm going to put the program on a device without a display. Can I manage the program directly from the terminal?

Are you still going to install necessary libraries for GTK and Xwindow (XLib) on your system?

Audio-recorder has been compiled and linked against those display libraries and it needs them to function. It is a GUI program.

Nevertheless it is possible to control audio-recorder from a terminal window.

Run audio-recorder --help and look for the -c, --command option.

-c, --command option:
Sends a command to the recorder.
Valid commands are; status,start,stop,pause,show,hide and quit.
The status argument returns; 'not running','on','off' or 'paused'.

For example:
$ audio-recorder --command=hide
$ audio-recorder --command=start
$ audio-recorder --command=pause
$ audio-recorder --command=show
$ audio-recorder --command=status
--> paused
$ audio-recorder --command=stop

Notice that parec or arecord programs a better options if you are running a pure terminal environment (without xwindow).

One good solution is to use Gstreamer directly !
It does not need GUI libraries.

Please start audio-recorder and go into the [Additional settings] dialog. Choose the [Recording commands] tab. There you can see the actual Gstreamer commands that do the recording work. There are Gstreamer pipelines for various codex and formats (.mp3, .ogg, flac, etc.) . Use the [Show Cmd] button to see and test the pipelines in a terminal window.

You will need to install gstreamer1.0-tools package.
It contains the gst-launch-1.0 command.

Become also familiar with the pactl command that is explained in the dialog.

Can you help with this problem?
