如何使用Python做个自定义动态壁纸

时间:2021-12-25 00:27     来源/作者:Dragon少年

使用python做个自定义动态壁纸

首先一起来看看最终实现的自定义动态壁纸效果:

如何使用Python做个自定义动态壁纸接我

接下来,我们开始介绍这个自定义动态桌面的制作过程。

一、核心功能设计

总体来说,我们需要实现将自己喜欢的视频转成一个动态桌面,知识点主要包含了对视频提取解析视频轮播pyqt5窗体设置桌面句柄获取自定义动态桌面壁纸实现等。

大致可以整理出我们需要分为以下几步完成:

  1. ui排版布局设计,确认动态壁纸功能设计
  2. 加载视频,对视频进行预览读取,保存视频路径等
  3. 动态壁纸功能实现应用,获取桌面句柄,轮播加载视频
  4. 关闭动态壁纸,在线壁纸资源获取等

二、实现步骤

之前有粉丝反馈说,想自己跟着文章自己敲敲代码,但是不知道具体需要哪些模块、包文件,后面我就把所有用到模块先放出来。

from os import path as pathq

1. ui排版布局设计

根据动态壁纸所需要的功能,首先进行ui布局设计,我们这次还是使用的pyqt5。主要包含了加载读取本地视频、视频加载预览、动态壁纸应用、动态壁纸关闭等。核心设计代码如下:

ui实现效果如下:

ui布局设计完成,下面我们开始进行视频读取加载、预览功能实现。

2. 视频加载预览

接来下我们可以根据自己喜欢的视频,从本地读取视频,并且将视频预览播放显示。这里视频演示,博主还是用之前的那篇紫颜小姐姐的跳舞视频进行演示。

读取视频:

读取视频我们可以通过打开文件对话框,选择视频资源,开启一个子线程用来进行视频开启停止播放。核心代码如下:

def openmp4(self):
    try:
        global path
        path, filetype = qfiledialog.getopenfilename(none, "选择文件", '.',
                                                     "视频文件(*.avi;*.mov;*.rmvb;*.rm;*.flv;*.mp4;*.3gp)"# ;;all files (*)
        if path == "":  # 未选择文件
            return
 
        self.slotstart()
        t = thread(target=self.stop)
        t.start()  # 启动线程,即让线程开始执行
    except exception as e:
        print (e)

视频流读取播放:

接下来,我们需要对视频文件进行按帧读取加载显示,并通过计时器实现动画效果。核心代码如下:

def slotstart(self):
    videoname = path
    if videoname != "":  # “”为用户取消
        self.cap = cv2.videocapture(videoname)
        self.timer_camera.start(50)
        self.timer_camera.timeout.connect(self.openframe)
 
# author:服务器之家
def openframe(self):
    if (self.cap.isopened()):
        ret, self.frame = self.cap.read()
        if ret:
            frame = cv2.cvtcolor(self.frame, cv2.color_bgr2rgb)
            if self.detectflag == true:
                # 检测代码self.frame
                self.label_num.settext("there are " + str(5) + " people.")
            height, width, bytespercomponent = frame.shape
            bytesperline = bytespercomponent * width
            q_image = qimage(frame.data, width, height, bytesperline,
                             qimage.format_rgb888).scaled(self.label.width(), self.label.height())
            self.label.setpixmap(qpixmap.fromimage(q_image))
        else:
            self.cap.release()
            self.timer_camera.stop()  # 停止计时器

至此,我们已经可以实现视频读取加载,并且进行视频预览了,效果如下:

3. 动态壁纸功能实现

实现桌面壁纸替换,我们首先需要获取桌面句柄找到桌面窗体,覆写桌面窗体、调用加载的视频流,播放动态壁纸。

获取桌面句柄:

def pretreatmenthandle():
    hwnd = win32gui.findwindow("progman", "program manager")
    win32gui.sendmessagetimeout(hwnd, 0x052c, 0, none, 0, 0x03e8)
    hwnd_workw = none
    while 1:
        hwnd_workw = win32gui.findwindowex(none, hwnd_workw, "workerw", none)
        if not hwnd_workw:
            continue
        hview = win32gui.findwindowex(hwnd_workw, none, "shelldll_defview", none)
        # print('hwmd_hview: ', hview)
        if not hview:
            continue
        h = win32gui.findwindowex(none, hwnd_workw, "workerw", none)
        while h:
            win32gui.sendmessage(h, 0x0010, 0, 0# wm_close
            h = win32gui.findwindowex(none, hwnd_workw, "workerw", none)
        break
    return hwnd

桌面覆写:

我们可以创建一个类,对窗体进行继承,进行视频流加载读取播放。核心代码如下:

class mymainwindow(qmainwindow, ui_mainwindow):
    def __init__(self, parent=none):
        super(mymainwindow, self).__init__(parent)
        self.ui = ui_mainwindow()
        self.ui.setupui(self)
        self.player = qmediaplayer()
        self.player.setnotifyinterval(10000)
        self.player.setvideooutput(self.ui.videowidget)
        self.player.setmuted(bool(1 - self.player.ismuted()))
        self.setwindowflags(qt.framelesswindowhint)
        self.setupui(self)
        self.go()
 
 
 # author: 服务器之家
    def go(self):
        self.ui.videowidget.setfullscreen(true)
 
        with open("./filename.txt", 'r', encoding='utf-8') as f:
            file_name = f.read()
            if file_name =='':
                file_name = 'lkf.mp4'
        print (file_name)
        if not os.path.exists(file_name):
            sys.exit()
        media = qmediacontent(qurl(file_name))
        self.player.setmedia(media)
        self.mplaylist = qmediaplaylist()
        self.mplaylist.addmedia(qmediacontent(qurl.fromlocalfile(file_name)))
        self.player.setplaylist(self.mplaylist)
        self.mplaylist.setplaybackmode(qmediaplaylist.currentiteminloop)
        win_hwnd = int(self.winid())
        video_h = int(self.ui.videowidget.winid())
        win32gui.setparent(win_hwnd, h)
        win32gui.setparent(video_h, h)
        win32gui.setparent(video_h, win_hwnd)
        self.player.play()

这里我们把上面的py文件直接打包成exe文件,接下来我们在“应用”控件上进行事件绑定,直接调用exe执行,实现动态壁纸播放应用功能。核心代码如下:

def play(self):
     if path == '':
         reply = qtwidgets.qmessagebox.question(self, '提示',
                                                "未加载选择视频",
                                                qtwidgets.qmessagebox.yes)
         return
     with open("./filename.txt", 'w', encoding='utf-8') as f:
         f.truncate(0)
         print(f.write(str(path)))
     try:
         try:
             call('taskkill /f /im play.exe')
         except:
             pass
         os.system('start play.exe')
     except:
         pass
     try:
         if self.cap != []:
             self.cap.release()
             self.timer_camera.stop()  # 停止计时器
         else:
             warming = qmessagebox.warning(self, "warming", "push the left upper corner button to quit.",
                                           qmessagebox.yes)
     except:
         pass

这样,我们就完成了动态壁纸加载应用功能了,效果如下:

4. 关闭动态壁纸

最后我们再实现下当前动态壁纸播放关闭功能,我们需要对当前桌面视频播放进行释放取消。代码如下:

         pass

效果如下:

至此,整个自定义动态桌面壁纸功能就全部完成了,下面我们一起运行下看看动态壁纸效果。
