Re: Recording live video stream from IP camera issue
Thanks for the advice! I looked into it, seems using windows was an issue, switched to ubuntu and it worked! Just wondering if you have used opencv for recording purposes? Or if you know of any python documentation for opencv2? Information is hard to come by! Thanks again, Sam -- http://mail.python.org/mailman/listinfo/python-list
Re: Recording live video stream from IP camera issue
Hi Xav, Iv been looking into OpenCV, i can easily stream my laptops webcam using this code. import cv2 cv2.namedWindow(preview) vc = cv2.VideoCapture(0) if vc.isOpened(): # try to get the first frame rval, frame = vc.read() else: rval = False while rval: cv2.imshow(preview, frame) rval, frame = vc.read() key = cv2.waitKey(20) if key == 27: # exit on ESC break However using the cv2.Videocapture(ip_address) method will not load my IP camera video feed into the new window. I can view the stream in any web browser or VLC using the IP address http://192.168.1.72:1025/videostream.cgi?user=pwd=resolution=8. Did you have this issue? Is there some lines of code i may need to add? Any help would be appreciated! Thanks, Sam -- http://mail.python.org/mailman/listinfo/python-list
Re: Recording live video stream from IP camera issue
Hi Sam, Did you compile your OpenCV with gstreamer? That's where I'd look first.

Recording live video stream from IP camera issue
Hey, I have no vast knowledge of python, but i came across this code to capture video from my IP camera import urllib2 import time import logging print Recording video... response = urllib2.urlopen(IP Address) filename = time.strftime(%Y%m%d%H%M%S,time.localtime())+.avi f = open(filename, 'wb') video_file_size_start = 0 video_file_size_end = 1048576 * 20 # end in 20 mb block_size = 1024 while True: try: buffer = response.read(block_size) if not buffer: break video_file_size_start += len(buffer) if video_file_size_start video_file_size_end: break f.write(buffer) except Exception, e: logging.exception(e) f.close() This code works, however when i try to playback the .avi file in VLC player (file wont open in any other media player) it just flashes an image instead of a video file, even though the .avi file is around 20mb. Is there some extra lines of code i need to include or change? Perhaps a timing option instead of a file size? Any help or insight would be much appreciated!!

Where did you get this code? it just flashes an image instead of a video file, even though the .avi file is around 20mb. Does your camera actually generate video? If your camera is just generating a single still image every few seconds, then the recorded file will be one frame followed by many frames of nothing, then you'll hit the 20MB limit before the next still picture is taken. If your camera does generate video, what sort of video does it generate? If it generates (say) mp4 and you are shoving it into a avi file, it could very likely confuse most media players. If you are on Linux, try this: - rename the file *without* the .avi at the end; - at the shell command line, give the command file name-of-your-video-file and see what the file command thinks it contains. -- Steven -- http://mail.python.org/mailman/listinfo/python-list

I've been working with several IP cameras with Python and OpenCV. It's a bit of a hassle, but it is not difficult. However I will say that VLC can open a network location and save the video at the same time. If all you want to do is capture and save, Python is not necessary.

Re: Recording live video stream from IP camera issue
Thank you for the quick reply! I found this code just from multiple google searches, but yer it mentioned online video streaming, however my IP camera would be streaming in Mjpeg format (I thought been able to convert between the two formats seemed way to easy!) So i'm guessing its just 20mb of a picture and then nothing. Could you give any insight into how to record an mjpeg stream? External libraries for me to consider etc?

Re: Recording live video stream from IP camera issue
Hi, This is for a university project. My issue is that i have built an App using pythons Kivy module, and i need to be able to stream and record from an IP camera upon request. I have just used the VLC.exe to stream the video feed. But it is the recording i am having problems with. I'l look into OpenCV, thanks for the help!

In that case, cv2.VideoCapture(ip_address) should return you a video object, which you can check for status and use its .read() method to fetch a frame. :] Cheers, Xav -- http://mail.python.org/mailman/listinfo/python-list
