I used pygame and mplayer library to play a m4a music file in python languages,but all failed. Is there a library i can use to play m4a file in python?
here is my code:
pipes = dict(stdin=PIPE, stdout=PIPE, stderr=PIPE)
mplayer = Popen(["mplayer", r"C:\Users\sam\PycharmProjects\untitled\music.m4a"], **pipes)
# to control u can use Popen.communicate
mplayer.communicate(input=b">")
sys.stdout.flush()
i used the pycharm ,and the result is :
Traceback (most recent call last):
File "C:/Users/sam/PycharmProjects/untitled/tt.py", line 23, in
mplayer = Popen(["mplayer", r"C:\Users\sam\PycharmProjects\untitled\music.m4a"], **pipes)

Here is a link to a good thread that I believe answers the exact same thing that you are having issues with.

I made this script for compressing videos in Python 3:
import os
import sys
import subprocess
result = subprocess.run('ffmpeg -i output.mp4 -b 800k output.mp4')
print(result)
When I run the above, some error will come up like System cannot find the file specified :
result = subprocess.run('ffmpeg -i output.mp4 -b 800k output.mp4')
File "C:\Program Files\Python37\lib\subprocess.py", line 488, in run
with Popen(*popenargs, **kwargs) as process:

startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified
Question: How to fix code for correct compressing of videos?
Nearly correct! It looks like the only module you need is subprocess. You should run your command in run() function. Try this:
import subprocess
result = subprocess.run('ffmpeg -i output.mp4 -b 800k output.mp4')
print(result)
I have an audio file and I want to get the timestamps for each word. I want to know during which time period was each the words spoken.
(For example if an audio file says "I am a doctor" I want to know during which instant "I" was said, "am" was said and so on)
I want to do this using python.
I have tried the following code.
from SimpleAudioIndexer import SimpleAudioIndexer as sai
indexer = sai(mode="ibm", src_dir="D:/Codes/Python/audio recognition",
username_ibm="", password_ibm="")
indexer.index_audio(basename = "target.wav")
indexer.save_indexed_audio("{}/indexed_audio".format(indexer.src_dir))
indexer.load_indexed_audio("{}/indexed_audio.txt".format(indexer.src_dir))
print(indexer.get_timestamps())
However I am running into following error.
Traceback (most recent call last):

From what I can tell from your code/errors is that you're running Windows, but you're using forward slashes "/" in your src_dir string. This won't work as Windows uses the backslash "\" when navigating folders. Such as:
C:\Windows
while many Unix based systems use the forward slash like this:
/home/Awais
In your code you should try to change the "/" to "\" and see if that makes a difference.
If it is your intention on using this program on both Windows and Unix systems, you should use python3's "pathlib" to ensure your directory paths work on either OS. Here is a link that you can use to learn more about handling paths in python3:

I just want to convert my midi files to mp3 by using midi2audio, i use this code:
----------
from midi2audio import FluidSynth
FluidSynth().midi_to_audio('test.mid','test.mp3')
---------- or
from midi2audio import FluidSynth
FluidSynth().play_midi('test.mid')
but i got the same result:

So, i try to copy the fold "fluidsynth" to "midi2audio", but it still doesn't work. I have installed both midi2audio and fluidsynth, who knows what happened?
you must copy "fluidsynth" in some folder pointed by your PATH environ variable
( type "echo $PATH" in terminal app to see what is registered actually ).
On unix-like systems python will usually find fluidsynth located at /usr/bin/fluidsynth ( as /usr/bin is listed in the PATH ). on Os X things are not much different any documentation should fit. A common practice is to use /usr/local/bin folder for adding custom programs.
Maybe you should install fluidsynth first
for ubuntu:
sudo apt-get install fluidsynth
I have python script which prints out long list through statistical R (by PypeR). This python script is working absolutely fine.
Now I am trying to run this script from NodeJS through spawn functionality of child_process but it fails with following error:-
Traceback (most recent call last):
File "pyper_sample.py", line 5, in <module>

Note: My python script is working perfectly. I already tested it manually.
My python script is working perfectly. I already tested it manually.
The output clearly shows that OSError: No such file or directory exception happened during Popen() call.
It means that the program is not found e.g.,
>>> from subprocess import Popen
>>> p = Popen(["ls", "-l"]) # OK
>>> total 0
>>> p = Popen(["no-such-program-in-current-path"])
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
Also, passing the whole command as a string instead of a list (shell=False by default) is a common error:
>>> p = Popen("ls -l")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
Make sure:
your (child) program can be found in current $PATH
use a list argument instead of a string
test whether it works if you run it manually from a different working directory, different user, etc
Note: your Popen() call passes startupinfo that is Windows only. A string command with several arguments that would work on Windows fails with the "No such file or directory" error on Unix.
I use chardet for recognize my file encoding, but this error happend :
fh= open("file", mode="r")
sc= chardet.detect(fh)
Traceback (most recent call last):
File "/home/alireza/test.py", line 19, in <module>
sc= chardet.detect(fh)

aLen = len(aBuf)
TypeError: object of type '_io.TextIOWrapper' has no len()
and i can't open file with out know the encoding,
fh= open("file", mode="r").read()
sc= chardet.detect(fh)
Traceback (most recent call last):

(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc7 in position 34: invalid continuation byte
how to use chardet without open file ?! or any way to find out file encoding after/before opening ?
Try opening the file like this
fh= open("file", mode="rb")
Command Line Tool
If this does not work, try the command line tool of chardet.
Description from https://github.com/erikrose/chardet:
chardet comes with a command-line script which reports on the
encodings of one or more files:
% chardetect.py somefile someotherfile
somefile: windows-1252 with confidence 0.5
someotherfile: ascii with confidence 1.0
Not a direct answer, but you can find the description how it works in Python 3 here http://getpython3.com/diveintopython3/case-study-porting-chardet-to-python-3.html. After studying that, you may find the way how to detect another specific encoding.
The code was initially derived from Mozilla Seamonkey. You may find more information also there. Or look for some more advanced Python package related to Seamonkey.
