大神,请问有打算基于openpose将获取的视频流进行同时的实时姿态估计吗,
你好,我在拉rtsp流的时候,会出现:
[h264]....解码失败的问题.该怎么解决?
虽然解码失败,.但是cap.read()返回的ret,依然是True.
比如说我有多个视频流地址,类似与这样:
videoList = [
"rtmp://192.168.99.125:11935/hls/32010000001320000730_32010000001320000730",
"rtmp://192.168.99.125:11935/hls/32010000001320000727_32010000001320000727"
]
应该怎么抽帧?
比如说每隔2秒抽帧一次怎么弄?
and i will give this project 1 star~
怎么获取所有的摄像头啊,有函数么
我同时读取8路rtsp视频 CPU 100% 这个怎么解决!
你好朋友,我在树莓派3B+上编译了opencv-4.1.0版,用如下代码获取数据帧时只能得到不超过每秒10帧的数据,用imshow显示就是卡顿,摄像头是720P的,而且在windows10中用系统自带的照相机程序录制可以达到每秒接近30帧,这明显不是摄像头问题,是我代码写的有问题,还是树莓派硬件性能不行,望赐教。代码如下:
import cv2
import time
cap=cv2.VideoCapture(0)
cap.set(6,cv2.VideoWriter_fourcc(*'MJPG'))
cap.set(3,1280)
cap.set(4,720)
cap.set(5,30)
print cap.get(3)
print cap.get(4)
print cap.get(5)
count=0
t=int(time.time())
while True:
ret,frame=cap.read()
if ret:
if int(time.time())-t==0:
count+=1
else:
print("%s: %s" % ('fps',count))
count=0
t=int(time.time())
运行结果输出:
1280.0
720.0
30.0
fps: 0
fps: 6
fps: 10
fps: 10
