学习笔记:在UBUNTU平台下的基于Tkinter和pydub的音乐播放器

作者:互联网

一、总述

        这是一个学习笔记。市面上的播放器很多,所以为什么要做这件事呢,一点是希望在做这个软件的过程中学到一些知识,还有是因为像酷狗、QQ音乐这些软件经常在网上被爆出恶意删除本地音频的行为,而groove没办法播放歌词,千千静听算是比较好的一个本地播放设备了,但是总归没有自己写来的自由。

        本文实现了一个在ubuntu平台下正常可执行文件封装的几乎全格式音乐播放器;在win平台下由于pydub的FFmpeg依赖会弹出命令行,由于水平限制,目前仅能实现有命令行窗口的exe封装。对于本文的不足,希望各位指教。

 

 二、文件结构

总共分为三个文件:

all_music.py 基于pydub,用于获得音乐类,可实现歌曲载入、播放、长度获取、播放时间获取、倍速播放、暂停、终结所有播放进程、播放状态获取等功能

show2.py 基于tkinter,用于播放器界面的可视化,之后预期添加音量加减,喜欢列表等功能。

main2.py 居中调度,用于传递文件路径,获取歌词和歌曲列表等功能。

三、打包方式

        使用pyinstaller -w -F -n 目标名称 文件名称的方式(比如这里是pyinstaller -w -F -n my_music main2.py)进行打包。

        笔者经过了很多次的尝试,在网上也找了很多的方法,但都没办法修改这个图标,我看到一篇文章,貌似是因为Ubuntu系统限制,无法修改这个图标,不知道大家有没有什么办法。

        笔者直接在/usr/share/application这儿新建了一个My_Music.desktop 文件链接了这个可执行文件和图片,所以就有了如下效果:

 

My_Music.desktop设置如下:

[Desktop Entry]    #必须要的,告诉系统这是什么
Version=1.0        #可选,显示版本信息
Name=My_Music        #软件名称
Comment=A Music Player    #鼠标放在图标上时显示的文字
Exec=/home/xiaobai/Desktop/my_music/my_music    #可执行文件路径(绝对路径)
Icon=/home/xiaobai/Desktop/my_music/My_Music.jpeg    #希望作为软件图标使用的图片,这张是百度的,最好是正方形,也可以下下来自己裁
Encoding=UTF-8        #可选,编码方式
StartupNotify=true    #现在还不清楚有什么用
Terminal=false        #是否打开命令行
Type=Application    #类型
Categories=Audio;Player    #类别,这里选的是音乐播放器,具体可选值可自行百度

 四、main2.py
