opencv_videoio_ffmpeg.dll和opencv_videoio_ffmpeg_64.dll
我很抱歉,但是你的问题并不是一个问题,而是一段代码。你似乎想让我解释如何将输入视频界面框像素提高。如果我理解得正确,你可以使用 OpenCV 库中的 resize() 函数来实现。以下是一个示例代码片段,将输入视频帧的大小调整为原始大小的 1.5 倍:
```
import cv2
cap = cv2.VideoCapture(filepath)
while cap.isOpened():
success, frame = cap.read()
if not success:
print("Ignoring empty camera frame.")
break
# 改变视频帧大小为原始大小的1.5倍
scale_percent = 150 # 放大比例为150%
width = int(frame.shape[1] * scale_percent / 100)
height = int(frame.shape[0] * scale_percent / 100)
dim = (width, height)
resized_frame = cv2.resize(frame, dim, interpolation = cv2.INTER_AREA)
# 显示视频帧
cv2.imshow('Resized Frame', resized_frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
```
希望这可以帮到你!
