问题描述

我正在尝试使用 Python PyQt5 运行一个程序,在该程序中我获取 2 个摄像头的 ip 并将它们实时流式传输到我的屏幕上,但是流就像给定图片中的一样(查看第一张图片),两个流都来了在前半部分,但我真正想要的是将它们分成两半(查看第二张图片以便更好地理解)水平布局的代码顶部布局,而不是仅在屏幕的第一半部分(我也是正在获取这些黑色边框,如果有人知道如何将其删除,我将无法删除它们,请告诉
在视频流位于底部布局的顶部布局之后,我试图获取一个图表和一个空的小部件我可以编辑以备后用。

提前致谢

解决方案


嘿,所以我能够用我已经拥有的代码解决一些问题,所以我将只在 pyqt 上流式传输视频,并使用子进程调用我使用 MATLAB 制作的 .exe 文件,所以你去看看。 (这里我现在还没有调用子进程)
