jack_capture stops recording instantly when started remotely or on boot

[francis669]

hello! im hoping that someone could shed some light on this cause i cant find any info around, jack_capture works well when i start it from the command line, however - i have a python script that reads a GPIO button and trigger jack capture, this also works fine when started from command line but when automated on boot it starts to record and stops immediately,
i also tried to trigger the command from pure data using "shell" and got the same behaviour. i wonder if anyone knows what im doing wrong? here is the output:

`main() find default file format
main() find filename
main() init jack 1
buf_size_in_bytes: 4104
main() init buffers
bufinit1. sizeof(long): 4, sizeof(float): 4, sizeof(double):8, sizeof(int):4, sizeof(void*):4
main() Open soundfile and setup disk callback.
main() Init waiting.
main() Init jack 2.
main() Everything initialized.
main() Start meterbridge.
main() Print some info.

Recording to "jack_capture_53.wav". Press or to stop.
main() Start helper thread.
main() Wait.
STDOUT: >>> Please wait while writing all data to disk. (shouldn't take long)

I don't know. You should search for SEM_SIGNAL(stop_sem); in jack_capture.c, and add a printf("...\n") before every call to SEM_SIGNAL(stop_sem) so that we know why it was stopped.
