Python VLC Script error: AttributeError: 'NoneType' object has no attribute 'media_player_new'

I solved the problem by comment out find_lib() in vlc.py.

p = os.getcwd()
os.chdir(os.path.join(p, 'sdk'))
dll = ctypes.CDLL("libvlc.dll")
plugin_path = os.path.join(os.getcwd(), r'sdk\plugins')

You are not holding the instance open

import vlc
Instance = vlc.Instance()
player = Instance.media_player_new()
Media = Instance.media_new('2005.mp3')
Media.get_mrl()
player.set_media(Media)
player.play()
while player.get_state() !=6:
    continue

Should work or
try this:

import vlc
import time
import sys

def progressbar(progress,guage_length=50):
    div = 100 / float(guage_length)
    prog = int(progress / div) # ensure progress fits in guage
    text = "\rPlaying: {0}{1}{2} [{3}%]".format(">"*prog,"|","-"*(guage_length - prog),format(progress,'.2f'))
    sys.stdout.write(text)
    sys.stdout.flush()

instance = vlc.Instance()
player = instance.media_player_new()
player.set_mrl("V2.mp4")
player.play()
playing = set([1,2,3,4])
play=True
guage_length=30
while play == True:
    time.sleep(0.5)
    play_state = player.get_state()
    if play_state in playing:
        length = player.get_length()
        ptime = player.get_time()
        progress = ptime/float(length)*100
        progressbar(progress,guage_length)
        continue
    else:
        progressbar(100,guage_length)
        play = False
print ("\nPlay terminated")

Note that # State 0: None,1 Opening,2 Buffering,3 Playing,4 Paused,5 Stopped,6 Ended,7 Error

Caveat: tested on Linux only

You could simplify your code using simply

import vlc
p = vlc.MediaPlayer('2005.mp3')
p.play()

but this would not solve your problem. Apparently, the vlc instance is not correctly created. This can be caused by a variety of issues. Use

i = vlc.Instance('--verbose 3')

to see possible error messages.

I got this error message on a Raspberry Pi Zero with Raspbian Buster Lite. I searched a long time for the answer but suddenly I noticed the remark on the pypi project page of python-vlc:

Note that it relies on an already present install of VLC.

So installing vlc with sudo apt install vlc solved the problem!

The fix of AttributeError: 'NoneType' object has no attribute 'media_player_new' for onefile for windows is --add-data "./plugins/;./plugins/" make sure that plugins is in the same path as main.py

Make sure to copy plugins folder from the VLC binary path before launching the command also don't forget to add DLLs files too with :

--add-data "libvlc.dll;." --add-data "libvlccore.dll;." --add-data "axvlc.dll;." --add-data "npvlc.dll;."
