Hi. I try to send a live stream from videocapture directly. But it appear error : message too long Do i need process the stream before sending? I hope someone can do me a favor . THX in advance. here is my testing code: import cv2 from socket import *

cap = cv2.VideoCapture(0)

sock = socket(AF_INET, SOCK_DGRAM)

while (cap.isOpend()): t, frame = cap.read() ser.sendto(frame, addr)

cap.release() cv2.destoryAllWindows()

thx anyway

i just wanna real-time transport the video stream ... and the rtp is what i think of the first protocol

I am a beginner in opencv(python) and spent a lot of time . I want to record video and real-time transport to the other server. here is the code. import cv2

cap = cv2.VideoCapture(0)

out = cv2.VideoWriter('output.avi', cv2.cv.CV_FOURCC('M', 'J', 'P', 'G'), 20.0, (640,480))

while(cap.isOpened()): ret, frame = cap.read() if ret == True:

    out.write(frame)

    cv2.imshow('show', frame)
    if cv2.waitKey(1) & 0XFF == ord('q'):
        break

cap.release() out.release() cv2.destroyAllWindows()

i don't know what type of data is 'frame' and how to process it to be a stream to transport to the another server in real-time. hope someone help me to solve this problem
