我正在尝试使用以下代码在 python 中使用 cv2 从 GoPro 捕获实时流:
VIDEO_URL = "http://10.5.5.9:8080/live/amba.m3u8"
cam = cv2.VideoCapture(VIDEO_URL)
cv2.namedWindow("GoPro",cv2.CV_WINDOW_AUTOSIZE)
while True:
f, im = cam.read()
cv2.imshow("GoPro",im)
if cv2.waitKey(5) == 27:
break
cam.release()
cv2.destroyAllWindows()
但收到以下错误:
WARNING: Couldn't read movie file http://10.5.5.9:8080/live/amba.m3u8
OpenCV Error: Assertion failed (size.width>0 && size.height>0) in imshow, file /tmp/opencv-MRl1/opencv-2.4.7.1/modules/highgui/src/window.cpp, line 261
Traceback (most recent call last):

File "gopro_simple.py", line 167, in live_stream
cv2.imshow("GoPro",im)
cv2.error: /tmp/opencv-MRl1/opencv-2.4.7.1/modules/highgui/src/window.cpp:261: error: (-215) size.width>0 && size.height>0 in function imshow
流在 vlc 中工作,代码与网络摄像头一起工作,所以看起来问题是 opencv 不喜欢 .m3u8 格式。任何有关如何解决此问题的想法/建议将不胜感激。谢谢。
