After some time, "recording audioProcess has exited with code = 0" #22

Closed chandywerks closed 6 years ago

chandywerks commented 6 years ago

I am using this package to capture audio input for days on end. It seems after a few hours it quits.

With debug set to true I see this error in the log,

recording audioProcess has exited with code = 0

Anyone else run in to this issue?

chandywerks commented 6 years ago

This seems to happen consistently after around 111851xx milliseconds of capture. A little over three hours.

I'm having this same issue. It exits, consistently, at 1 hr, 33 mins, and 12 seconds. That's also 5592 seconds, or of course 5,592,000 ms, which is basically half of your 111851xx ms number, which I find interesting. My recording options are 2 channels, 32-bit, 48000 Hz, signed integer, little endian.

Have you found a resolution to this issue? I am starting to think it is an issue with the arecord executable that this code is calling.

chandywerks commented 6 years ago

@cmvee I've been meaning to look into this issue, thanks for reminding me. My recording settings are also 2 channels at 48 KHz.

Just curious what distro are you using and what version of arecord is installed on it? I'm having this issue on a Raspberry Pi running Raspbian 9.1 and arecord version 1.1.3

cmvee commented 6 years ago

@chandwki I am running latest Raspbian Stretch. uname -a gives Linux 4.14.30-v7+ #1102 SMP Mon Mar 26 16:45:49 BST 2018 armv7l GNU/Linux. I've tested in a Pi 3B and 3B+. Both have issues.

I edited the mic code and found that having it use sox instead of arecord resolves the issue, so this means it's a limitation of arecord, but I still haven't determined the root cause of why arecord exits.

cmvee commented 6 years ago

@chandwki I resolved this issue in https://github.com/ashishbajaj99/mic/pull/25 by passing the fileType option to the spawned arecord process. More detail on the root cause if you click through above to the pull request. I have had no issue with arecord exiting since making this change.

Hopefully @ashishbajaj99 can consider merging the pull request. Thanks!

@cmvee well done!

@ashishbajaj99 I can confirm that PR #25 fixes this issue for me. Could you please merge it?

ashishbajaj99 commented 6 years ago

Sure, thanks a lot guys!
