Модуль VLC в Python – подробно с примерами

В данном руководстве мы разберемся с модулем VLC на языке программирования Python, его импортом. Мы также выполним несколько примеров на основе модуля Python VLC.

Что такое модуль VLC в Python?

Медиаплеер VLC в Python – это бесплатное программное обеспечение для медиаплеера с открытым исходным кодом, которое переносимо и может использоваться на нескольких платформах. Медиаплеер VLC также является сервером потокового мультимедиа, спроектированным и разработанным проектом VideoLAN. VLC – это медиаплеер, доступный в операционных системах для настольных ПК, таких как Windows, Linux и MacOS, а также на мобильных платформах, таких как Android, iOS, iPadOS, Windows 10 Mobile, Windows Phone и Tizen.

Мы также можем использовать медиаплеер VLC с помощью Python. Python предлагает поддерживаемый модуль, известный как VLC в Python.

Как установить модуль VLC в Python?

Чтобы установить модуль VLC в Python, мы будем использовать установщик pip, следуя команде, показанной ниже.

Примечание. Перед использованием модуля VLC в Python в пользовательской системе должен быть установлен медиаплеер VLC.

После завершения установки мы можем проверить это, импортировав модуль VLC в скрипт Python.

# importing the vlc module import vlc

Теперь нам нужно сохранить файл и запустить его. Если программа не выдает ошибок, модуль установлен правильно. В противном случае рекомендуется переустановить модуль и прочитать официальную документацию для получения более подробной информации.

Исправление ошибок, которые могут возникнуть при импорте модуля

  1. Если путь не определен, проблема в том, что dll отсутствует в PATH (системная переменная). Мы должны включить путь к файлу libvlc.dll в системную переменную, чтобы решить проблему. Можно найти этот файл в папке VLC, где он установлен.
  2. Неправильная версия VLC: обычно пользователи устанавливают 32-битную версию VLC, что может вызвать некоторые проблемы, если установлена 64-битная версия Python. Все, что нам нужно, это переустановить 64-битную версию VLC, чтобы это исправить.
  3. Мы можем импортировать модуль ОС перед модулем VLC и зарегистрировать dll, используя следующий синтаксис:
os.add_dll_directory(r'C:\Program Files\VideoLAN\VLC')

Некоторые примеры модуля VLC

Рассмотрим простую программу для воспроизведения видео с помощью VLC.

# importing the vlc module import vlc # creating the vlc media player object my_media = vlc.MediaPlayer("video.mp4") # playing video my_media.play()

В приведенном выше фрагменте кода мы импортировали модуль VLC. Затем мы создали объект медиаплеера VLC. Наконец, мы использовали функцию play() для воспроизведения видео.

Теперь давайте рассмотрим другой пример получения продолжительности видеофайла с помощью модуля VLC.

# importing the time and vlc modules import time, vlc # defining the method to play video def vlc_video(src): # creating an instance of vlc vlc_obj = vlc.Instance() # creating a media player vlcplayer = vlc_obj.media_player_new() # creating a media vlcmedia = vlc_obj.media_new(src) # setting media to the player vlcplayer.set_media(vlcmedia) # playing the video vlcplayer.play() # waiting time time.sleep(0.5) # getting the duration of the video video_duration = vlcplayer.get_length() # printing the duration of the video print("Duration : " + str(video_duration)) # calling the video method vlc_video("video.mp4")

В приведенном выше фрагменте кода мы импортировали модули time и VLC, определили функцию для воспроизведения видео. Внутри функции мы создали экземпляр и медиаплеер, а также создали носитель и установили его на плеер. Затем мы воспроизвели видео и установили время ожидания 0,5; сохранили продолжительность видео и распечатали его для пользователей. Наконец, мы вызвали определенную функцию.

How to Play Sound, Audio or MP3 Files in Python

How to Convert PNG to TIFF in Python?

There are numerous ways for us to play sound, audio, or MP3 files using the Python programming language. These include modules such as playsound , VLC , pygame , mpg123 , etc. We can also play it natively on macOS and Linux as we will see later on.

Most of the modules that we will be using don’t come pre-installed with Python, which means we will have to install them ourselves. Therefore, you need to have Python and PIP installed on your system, before installing these Python modules.

Luckily, playing audio in Python is straightforward and can be done with a few lines of code. In this guide, we will be going over the steps to play sound, audio, or MP3 files in Python on Windows , Linux , and macOS .

Note: In this guide, a 4-second MP3 file is used named testaudio.mp3 and it is located in the same directory as the .py file which we will be using to run the code.

Playing Sound, Audio, or MP3 Files in Python on Windows

Using Playsound

Playsound is a cross-platform Python module with no dependencies and a single function.

So, to use playsound to play audio:

play, read, open or run sound, audio or MP3 files in Python on Windows using playsound with Command Prompt command

If you would like to double-check that you’ve properly installed the module, enter python in the terminal to access the python terminal and then import playsound . If playsound is installed, there should be no errors in the output.

play, read, open or run sound, audio or MP3 files in Python on Windows using playsound with Command Prompt command

You can also enter pip list in the terminal to have a look at all the installed packages and their versions.

play, read, open or run sound, audio or MP3 files in Python on Windows using playsound with Command Prompt command

import playsound playsound.playsound('testaudio.mp3')

play, read, open or run sound, audio or MP3 files in Python on Windows using playsound

  1. After running the code, your audio will begin playing and will stop automatically depending on the length of your mp3 file.

Using VLC

VLC is an open-source and cross-platform media player that can be used to play audio and video files. VLC has a python module that enables us to play mp3 files.

Hence, to use VLC to play audio:

play, read, open or run sound, audio or MP3 files in Python on Windows using vlc

Confirm the installation by entering:

play, read, open or run sound, audio or MP3 files in Python on Windows using vlc

  1. We will be using another module alongside the Python VLC module in order to delay the execution of the file. The time module enables us to determine how long we want the file to delay execution so we can hear our audio being played. Otherwise, the file will finish executing immediately without our audio being played.
  2. In your code editor, enter the following:
import vlc import time p = vlc.MediaPlayer(‘testaudio.mp3’) p.play() print("The audio will finish playing in 4 seconds") time.sleep(4) p.stop()

play, read, open or run sound, audio or MP3 files in Python on Windows using vlc

The time.sleep(4) function tells the program to delay execution for 4 seconds before we call the p.stop() function. When running the program, it should look something like this:

play, read, open or run sound, audio or MP3 files in Python on Windows using vlc

A terminal window will appear and your audio should start playing. At the same time, the result of the print function is shown to indicate that the audio is 4 seconds long. The program will finish executing right after as that is the time we specify in time.sleep(4) .

Using Pygame

Pygame is a game development module that is cross-platform and enables us to use Python for graphics and audio purposes.

To use pygame to play audio:

play, read, open or run sound, audio or MP3 files in Python on Windows using pygame

import pygame import time pygame.mixer.init() # initialize mixer module pygame.mixer.music.load('testaudio.mp3') pygame.mixer.music.play() print("Audio will play for 4 seconds") time.sleep(4)

play, read, open or run sound, audio or MP3 files in Python on Windows using pygame

The result will look like this:

play, read, open or run sound, audio or MP3 files in Python on Windows using pygame

First, the audio will start playing, and the result of the print function will be shown on the screen. Then, the program will finish executing after 4 seconds as specified by the time.sleep() function.

Playing Sound, Audio, or MP3 Files in Python on Linux

Using Playsound

play, read, open or run sound, audio or MP3 files in Python on Linux using playsound

import playsound playsound.playsound(‘testaudio.mp3’)

play, read, open or run sound, audio or MP3 files in Python on Linux using playsound

play, read, open or run sound, audio or MP3 files in Python on Linux using playsound

Using os and mpg123

os is a standard Python module that doesn’t need to be installed. It allows us to interact with our Operating System through its functions. mpg123 is an open-source mp3 player for Linux systems.

So, we can use methods from both these functions to play audio files with Python through the following steps:

play, read, open or run sound, audio or MP3 files in Python on Linux using mpg123

import os os.system(‘mpg123 ‘ + ‘testaudio.mp3’)

play, read, open or run sound, audio or MP3 files in Python on Linux using mpg123

play, read, open or run sound, audio or MP3 files in Python on Linux using mpg123

Playing Sound, Audio, or MP3 Files in Python on macOS

Using Afplay and os

To play audio on a macOS-based machine, we will be using afplay and os . Afplay is a tool that allows us to play audio from a file on macOS.

import os os.system(“afplay ” + “testaudio.mp3”)

Conclusion

Learning how to play audio, sounds, and MP3 files in Python can be quite useful in many circumstances. There are a number of reasons why someone may want to play music or audio in Python.

These include wanting to add to their programming skills, adding music to a game, adding sound effects to an app, and many more!

With that said, in this article, we looked at the steps to play sound , audio , or MP3 files in Python on Windows , Linux , and macOS machines . We hope you’ve found this guide helpful when it comes to playing audio in Python.

Feel free to share this post with your fellow coders to guide them through playing sound, audio, or MP3 files with Python on Windows, Linux, and macOS!
