Pydub and Aplay: suppress verbose output? - python-2.7

Question

I'm trying to suppress the output of aplay, but without success.
I know how to suppress print statments with stdout, but I didn't figured out how to archive the same result with pydub module.
For example when I play a sound with this code
from pydub import AudioSegment
from pydub.playback import play
next_kot = AudioSegment.from_ogg('/home/effe/Voz/Hello.ogg')
play(next_kot)
The output generated (in red!) is
avplay version 9.18-6:9.18-0ubuntu0.14.04.1, Copyright (c) 2003-2014
the Libav developers built on Mar 16 2015 13:19:10 with gcc 4.8
(Ubuntu 4.8.2-19ubuntu1) Input #0, wav, from '/tmp/tmp5DUj0a.wav':
Duration: 00:00:01.32, bitrate: 1411 kb/s
Stream #0.0: Audio: pcm_s16le, 44100 Hz, 2 channels, s16, 1411 kb/s
When you concatenate more audio is easy to lose key information.
Is there a way to cut off this kind of output?
Thanks.

Answer 1

I ran into this same issue and here is what I did. You can just create a new function named _play_with_ffplay_suppress and have the following code in it. The difference between the answer above and mine is that Jiaaro used
stdout=open(os.devnull, 'w')
stderr=os.stdout
and I used "devnull" after creating a variable with the same name. Very tiny difference but I hope it solves the error that you mentioned in the comment.
stderr=devnull
stdout=devnull
Here is my code:
#rhp - additional import added
import os
#rhp-custom function to supress output while playing mp3 files
def _play_with_ffplay_suppress(seg):
with NamedTemporaryFile("w+b", suffix=".wav") as f:
seg.export(f.name, "wav")
devnull = open(os.devnull, 'w')
subprocess.call([PLAYER,"-nodisp", "-autoexit", "-hide_banner", f.name],stdout=devnull, stderr=devnull)
For more information you can read about the call function in the subprocess module in Python here https://docs.python.org/3/library/subprocess.html.

Answer 2

the playback functions are really simple (and mostly included for easy use in the interactive python shell) - Your best bet is probably to make a copy of the playback code that is better suited to your needs:
if you're using ffplay this should work:
import os
from pydub.utils import get_player_name
PLAYER = get_player_name()
def play_with_ffplay(seg):
with NamedTemporaryFile("w+b", suffix=".wav") as f:
seg.export(f.name, "wav")
subprocess.call(
[PLAYER, "-nodisp", "-autoexit", f.name],
stdout=open(os.devnull, 'w'),
stderr=os.stdout
)
note: ffmpeg is always going to open a new window for ffplay though - I'd recommend installing pyaudio and using that for playback instead
