-b and --batch start GUI

[Michael Schwendt]

With 2.0.2 and 2.0.3 (possibly also 2.0.x), a command-line using -b or --batch, e.g

    soundconverter -b test.flac

starts the GUI.

[Jan Riepshoff (jriepshoff)]

The bug still occurs with 2.1.2 on Ubuntu 12.04

That's something different.

Obviously, /usr/bin/soundconverter uses GTK+ ("import gtk") which tries to initialize the GUI framework for X. I dunno whether the "batch mode" has ever been supposed to be a real CLI mode that works without X running.

[GautierPortet (kassoulet)]

It should work without a display.
Not really a requirement, but this is clearly a regression that can be fixed.

[Jan Riepshoff (jriepshoff)]

Don't know whether it really is something different from a user's perspective. I wanted to use soundconverter on my server to convert audio files in batch mode. This can't be done at the moment.

Is there a way to make the server "think" that he has a display?

[GautierPortet (kassoulet)]

You can try to "SSH -X" to it. This will use your current display.

[Michael Schwendt (mschwendt)]

Or use "Xvfb", the "X Virtual Frame Buffer".
