文件夹内容更改时，Kodi刷新幻灯片

Question

我使用Raspberry Pi来显示存储在文件夹中的图片的幻灯片。

但是，如果我在幻灯片放映期间将图片添加到文件夹，则新图片不会添加到幻灯片中。

如何在不中断幻灯片放映的情况下实现此行为？

Answer 1

向Kodi添加自动启动脚本：当Kodi启动时它会自动运行幻灯片，如果文件夹内容发生变化，则会刷新幻灯片。

此脚本来自此答案：https://discourse.osmc.tv/t/refresh-picture-library/4867/13

# ~/.kodi/userdata/autoexec.py
# On Kodi startup, automatically start a Slideshow
# Refresh the slideshow if the content of the folder has been updated

import xbmc
from os import listdir
from time import sleep

xbmc.log('[refresh-slideshow] Starting')

monitor = xbmc.Monitor()
picfolder = "/PATH/TO/FOLDER"

# Generate list of images and start slideshow
l1 = listdir(picfolder)
xbmc.executebuiltin('SlideShow(%s)' %(picfolder))
xbmc.log('[refresh-slideshow] Slideshow started, monitoring')

# Wait for slideshow to start
sleep(5)

# Monitor during slideshow
while not monitor.abortRequested():
    # If slideshow is still running, compare directory contents
    if xbmc.getCondVisibility('Window.IsActive(slideshow)'):
        l2 = listdir(picfolder)
        # Restart slideshow if directory contents have changed
        if l1 != l2:
            xbmc.log('[refresh-slideshow] Folder contents changed, restarting slideshow')
            xbmc.executebuiltin('SlideShow(%s)' %(picfolder))
            l1 = l2
    # If slideshow is no longer running (user has exited), exit script
    else:
        break

    # Wait for 60 seconds, break if abort is requested
    if monitor.waitForAbort(60):
        break

xbmc.log('[refresh-slideshow] Finished, exiting')

Answer 2

如果没有，请在Class中转换屏幕保护程序脚本。

使用YTD_Special = CALCULATE( [Total], FILTER( ALL(FactTable), FactTable[Date] >= DATE(YEAR(VALUES('Cut off date'[End of YTD])), 1, 1) && FactTable[Date] <= VALUES('Cut off date'[End of YTD]) ) )

创建另一个类来更新图像

threading

现在在屏幕保护程序运行的主import xbmc, xbmcgui, threading class MyMonitor(xbmc.Monitor): def __init__(self, *args, **kwargs): self.action = kwargs['action'] # do some action here....... def onScreensaverDeactivated(self): self.action() class ImgVideoUpdate(threading.Thread): def __init__(self, *args, **kwargs): self._get_items = kwargs['data'] threading.Thread.__init__(self) self.stop = False self.check_update = 50 # set thread to update images(in seconds) self.Monitor = MyMonitor(action=self._exit) def run(self): while (not self.Monitor.abortRequested()) and (not self.stop): count = 0 while count != self.check_update: # check for new images every 50seconds xbmc.sleep(200) count += 1 if self.Monitor.abortRequested() or self.stop: return self._get_items() 类中初始化ImgVideoUpdate

ScreensaverWindow
