要在点击按钮时停止录制并保存视频,您可以通过添加一个停止录制的标志变量来实现。以下是修改后的代码示例:
```python
import sys
import cv2
from showPic import Ui_MainWindow
from PyQt5 import QtGui
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
class videoShow(QMainWindow,Ui_MainWindow):
def __init__(self):
super().__init__()
self.setupUi(self)
self.recording = False
@pyqtSlot()
def on_pushButton_record_clicked(self):
camera_path = 0 # 0:自带摄像头 1:外接摄像头 "xxx.mp4" "rtsp://admin:pwd@192.168.2.10/cam/..."
capture = cv2.VideoCapture(camera_path) # 初始化播放器 流媒体
fourcc = cv2.VideoWriter_fourcc('M', 'P', '4', 'V') # XVID/DIVX MPEG MJPG X264
video_writer = cv2.VideoWriter("image/myself.mp4", fourcc, 25, (960, 540)) # 存放路径、、帧率fps、尺寸(且保证下面的frame也是这个尺寸)
self.recording = True
while self.recording:
flag, frame = capture.read()
if flag is False:
continue
frame = cv2.resize(frame, (960, 540))
video_writer.write(frame)
key = cv2.waitKey(25)
if key == 27:
break
video_writer.release()
@pyqtSlot()
def on_pushButton_stop_clicked(self):
self.recording = False
@pyqtSlot()
def on_pushButton_play_clicked(self):
video_path = "image/myself.mp4" # 已经录制好的视频路径
capture = cv2.VideoCapture(video_path) # 初始化播放器
while True:
flag, frame = capture.read()
if flag is False:
break
key = cv2.waitKey(25)
if key == 27:
break
capture.release()
if __name__ == '__main__':
app = QApplication(sys.argv)
ui = videoShow()
ui.show()
sys.exit(app.exec_())
```
在修改后的代码中,我们添加了一个名为`recording`的标志变量,用于跟踪录制状态。在`on_pushButton_record_clicked`函数中,我们在循环中检查`self.recording`的值,如果它为False,则停止录制并释放视频写入器。我们还添加了一个名为`on_pushButton_stop_clicked`的槽函数,用于在点击停止按钮时将`self.recording`设置为False,从而停止录制。请确保在UI文件中存在一个名为`pushButton_stop`的按钮,并将其与`on_pushButton_stop_clicked`槽函数关联。
