其实这个项目本来就不适合用 Python 写
原作者内存优化得太垃圾，把所有帧都放内存里…… 我这 4G 处理个 4 分钟压缩后 4M 的小视频都撑不过 1:00
我正在考虑是添加一个 gc 内存压力提示呢，还是用其他语言重写呢，还是换 pypy 呢 🤔
反正最后一部分 cv 是不可以继续用 Python 的，内存压力实在是太大了……

我觉得可以做一个 GUI，来支持时轴框选歌词区域。
horizontalLayout {
TextureView,
Sidebar(verticalLayout {
playerTime,
horizontalLayout { playerControl, btnNewCrop }
ListView(crops/*time rect*/),
TextView /*current_subtitle*/,
TextArea /*time_subtitles*/
})
}#pragma once
#include <QMainWindow>
namespace Ui {
class MainWindow;
}
class MainWindow: public QMainWindow { Q_OBJECT
public:
MainWindow(QWidget* parent = nullptr);
~MainWindow();
private slots:
void onShowToastClicked();
void onShowProgressSpinnerClicked();
void onShowProgressHorizontalClicked();
private:
Ui::MainWindow* ui;
}; 🤔 很久没写 Qt 了，应该默写下这个GitHub

原作者混合了 cv2 和 Python PIL 图像处理，我给它改回纯 cv2，方便使用……

我给改回来了，现在用的
cv2.imread 和 cv2.UMat 的 slice#Python #DontKnow https://stackoverflow.com/questions/18946662/why-shouldnt-i-use-pypy-over-cpython-if-pypy-is-6-3-times-faster

Why shouldn't I use PyPy over CPython if PyPy is 6.3 times faster?
I've been hearing a lot about the PyPy project. They claim it is 6.3 times faster than the CPython interpreter on their site.

实操把
frames.append 注释掉不会卡死，cv2 不存在内存泄漏问题，但是如何优化内存使用正在重构

说实在话，其实原作者的算法也没有什么问题，不仅在于……关键还是在于没有 windowing，数据一下子都处理完，不能按照固定的大小一部分一部分处理
#Python #code 真可怜，无用的代码被丢掉了…… 看来纪念下吧
