我正在开发一个屏幕捕获工具，这个工具旨在帮助软件开发人员了解用户如何最终崩溃应用程序。 这个想法是一旦鼠标开始移动就开始屏幕捕捉，5分钟后鼠标停止移动。 屏幕捕获通过子过程与ffmpeg正常工作，唯一剩下的问题（应用程序崩溃除外）是启动和停止屏幕捕获。 我怎样才能做到这一点？ 理想情况下，它可以与条件variables一起工作，甚至是一个testing鼠标是否在最后一秒移动的循环。 有什么机会python支持像OnMouseMove() ？
一个循环+ pywin32 ，像这样：
import win32api from time import sleep count = 0 savedpos = win32api.GetCursorPos() while(True): if count>20*5: # break after 5sec break curpos = win32api.GetCursorPos() if savedpos != curpos: savedpos = curpos print "moved to " + str(savedpos) sleep(0.05) count +=1
wxPython可以让你访问一整套你可以绑定的OnMouse事件。
考虑到我的替代方案，我认为这是正确的方式来处理我的问题，请注意我已经更新了代码，以支持远程桌面断开连接通过检查是否GetCursorPos()引发异常，也请注意当关闭远程桌面ffmpeg输出
[dshow @ ] real-time buffer full! frame dropped!
但输出文件看起来很好。 此脚本在Windows server 2012上进行了测试
