PyQt5 在 moviepy 连接视频时显示黑色 window 没有小部件
PyQt5 shows black window without widgets while moviepy is concatenating videos
连接两个视频文件时,PyQt window 完全是黑色的,没有任何小部件。背景颜色变为灰色,小部件仅在视频连接后显示。
我希望在连接视频时看到灰色 window 和我的小部件。
这是脚本:
import os
import sys
from PyQt5.QtWidgets import *
from moviepy.editor import VideoFileClip, concatenate_videoclips
class Window(QWidget):
def __init__(self):
super().__init__()
self.setWindowTitle("Using Labels")
self.setGeometry(50,50,350,350)
self.UI()
def UI(self):
text1=QLabel("Hello Python",self)
text1.move(50,50)
self.show()
def make_movie():
sep = os.sep
directory_stub = '.' + sep + 'src' + sep + "assets" + sep
clip1 = VideoFileClip(directory_stub + 'introoutro' + sep + "intro.mp4")
clip2 = VideoFileClip(directory_stub + 'introoutro' + sep + "outro.mp4")
final_clip = concatenate_videoclips([clip1,clip2])
final_clip.write_videofile("my_concatenation.mp4")
def main():
App = QApplication(sys.argv)
window=Window()
make_movie()
sys.exit(App.exec_())
if __name__ == '__main__':
main()
在整理视频时我看到了这个:
我想在视频处理期间看到它,但我只看到它 1. 处理完成后或 2. 如果我编辑代码以从不调用 make_movie():
感谢您的帮助。
串联是一项非常耗时的任务,因此它不应该 运行 在主线程上,因为它会冻结 GUI:
