Program exits after recording stopped in timemachine mode.

[inpowell]

Hello, I am using jack_capture version 0.9.71 (installed via apt-get in Ubuntu 16.04), with JACK in non-realtime mode.

Starting the program with jack_capture -tm in a terminal starts the program in timemachine mode as expected. After pressing return, the program gives the "writing data all to disk" and "Finished" messages, prints the line >>> Error: exec returned. and exits.

Is this the intended outcome? It would be preferable for me if the program continued and maintained the timemachine buffer from where the recording stops.

Example outputs:

• In timemachine mode:

~$ jack_capture -tm
Cannot lock down 82274202 byte memory area (Cannot allocate memory)
>>> Warning. Could not set higher priority for a SCHED_FIFO process using setpriority().
>>> Waiting to start recording of "jack_capture_05.wav"
>>> Press <Ctrl-C> to stop recording and quit.
>>> Recording. Press <Return> to stop.                                
>>> Please wait while writing all data to disk. (shouldn't take long) 
   |"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""|

01:|                                                                 |

• In normal mode:

~$ jack_capture

>>> Warning. Could not set higher priority for a SCHED_FIFO process using setpriority().
>>> Recording to "jack_capture_06.wav". Press <Return> or <Ctrl-C> to stop.

01:|                                                                 |

Thank you for the time and effort spent into this program! Regards, Ian

I think this is a bug that was fixed in 0.9.72.

It might work to give the full path to jack_capture:

/usr/bin/jack_capture -tm

Providing the full path worked in 0.9.71. Thank you for your help!
