Visualizer sometimes fails to re-open song again #10

Closed C-Kenny closed 4 years ago

C-Kenny commented 5 years ago

The visualizer appears to play the song the first time, but sometimes it can't play the same song again in quick succession.

Leading to errors like:

getsockopt(): Bad file descriptor

and 

Assertion 'pa_close(m->fd) == 0' failed at pulsecore/shm.c:288, function pa_shm_free(). Aborting.
Could not run the sketch (Target VM failed to initialize).

Closing the visualizer and waiting ~60s seems to resolve this. Thinking the file may remain open when though it's supposed to close() upon exit.

C-Kenny commented 5 years ago

I've added a safe exit keyboard shortcut as 'x'/'X' which tries to close safely and stop minim from having the file open but I still sometimes get this error.

C-Kenny commented 5 years ago

Running $ lsof ~/Music/Visualizer/<song_title> we can see that sometimes Processing itself still holds onto the file. Even when seemingly not using it..
