几个月前给朋友推荐过mpv，朋友非技术人员，而mpv只提供命令行工具，没有图形界面，周末下午逛github看到Gooey，觉得简单有趣，决定用它给mpv写一个简单的图形界面

需求很简单，通过点击桌面图标，之后选择电影文件，就能播放，而不需要使用图形界面，这应该是大多非技术用户习惯的操作。

mpv

mac下常见播放器有QuickTime，MplayerX，VLC。我之前用MplayerX居多，mpv 是 Mplayer 和 Mplayer2 项目的分支，目前活跃的开发者都转向开发 mpv。mpv基本可以满足一般用户的需要

mac下不同播放器的比较参考这里

Gooey

Turn (almost) any Python command line program into a full GUI application with one line

Gooey能轻易地把python命令行工具变为GUI应用，通过极少的代码

brew tap mpv-player/mpv
brew install mpv
which mpv # /usr/local/bin/mpv

使用:mpv /your/folder/yourfile.mp4

mpv在mac目前没有图形界面

Gooey

pip install Gooey //需要在sudo pip下安装，wxpython要求比较多,virtuanenv下比较麻烦，具体可以参考wxPythonVirtualenvOnMac

依赖wxpython，安装wxpython

brew install wxpython
cd /Library/Python/2.7/site-packages    
ln -s /usr/local/Cellar/wxpython/3.0.2.0/lib/python2.7/site-packages/wx-3.0-osx_cocoa/wx/ wx

cat mpv_gui.py

#!/usr/bin/env python
# encoding: utf-8
#import argparse
from gooey import Gooey, GooeyParser
import subprocess
import sys

def handle(args):
    filename = args.filename
    # 播放，调用系统服务（mpv）
    mpv = "/usr/local/bin/mpv"
    # todo:变为独立进程
    subprocess.Popen([mpv,filename])

@Gooey(language="chinese")
def main():
  parser = GooeyParser(description=u'mpv_gui')
  parser.add_argument('filename', help=u"请选择电影文件", widget='FileChooser')
  args = parser.parse_args()
  handle(args)

if __name__ == '__main__':
  main()

mv mpv_gui.py mpv_gui
chmod +x mpv_gui

之后点击mpv_gui文件即可选择播放电影

如果你想把这个工具打包成无依赖的系统软件，可以试试pyinstaller

Gooey安装不方便，文件选择用tkinter的tkFileDialog就好了

from Tkinter import Tk
from tkFileDialog import askopenfilename

Tk().withdraw() # we don't want a full GUI, so keep the root window from appearing
filename = askopenfilename() # show an "Open" dialog box and return the path to the selected file , 在命令行下层？
print(filename)

后来发现可以直接安装mpv.app，之后绑定格式和播放工具 （参考 全能高效的播放器 mpv）

brew install mpv --with-bundle
brew linkapps mpv
