Basically, a quick search in the search tool, would have given you the following pages:

http://answers.opencv.org/question/10949/error-streaming-video-from-server/

http://answers.opencv.org/question/8207/how-use-opencv-process-signal-input-is-stream/

Basically, the support for streaming media is very limited in OpenCV. It is not suggested using OpenCV purely for the functionality of streaming :)

My Android phone installed IP webcam apps. So I run it and have a stream [IP]:8080/videofeed I build Opencv244 on Ubuntu and get this stream very good. Now I want to programming on VS2010 ( Windows 7 64 bit). I have already builded Opencv244 ( http://docs.opencv.org/doc/tutorials/introduction/windows_install/windows_install.html ) but dont get my stream ?

I will repeat myself, do not use streaming for accessing your webcam. An android phone supports the access to the camera data directly. Take that approach...

No no ! I have a stream video by my phone. On Laptop I install Opencv to get this stream ! On Ubuntu 11.10 I have got this stream Now I want to get stream on Windows 7 64bit? And I have some problems with build OpenCV-2.4.4

Then my first post still exists. If by stream you mean a single video file, then use the following library: http://docs.opencv.org/modules/highgui/doc/reading_and_writing_images_and_video.html?highlight=video#VideoCapture. If this is not what you want to do and you actually want to stream between laptop and phone, again read the topics. Streaming is not well supported ...

Hi Steven ! On Ubuntu 11.10, I built OpenCV-2.4.4 successfully by Cmake-GUI ( I did it follow this link http://karytech.blogspot.com/2012/05/opencv-24-on-ubuntu-1204.html ). When I ran my project on Qt Creator, I had been got my stream. Now I built OpenCV on Windows 7 and VS2010, I think I build successfullly but it doesn't get my stream with some errors "Could not find codec parameters ( ../../modules/highgui/src/cap_ffmpeg_impl.hpp:540". Do I have to build FFMEPG for windows first? Thank for reading !

You have to get the latest ffmpeg version for windows and then build openCV with that version as far as I know of. However, I have never done this myself before.

Hi Steven First I built FFmpeg on this link ( http://ffmpeg.mplayerhq.hu/download.html ) version 1.2 . Then I compile OpenCV-2.4.5 by Cmake-GUI. And I configure it same like that:

Video I/O:
    Video for Windows:           YES
    ***FFMPEG:                      YES (prebuilt binaries)***
      codec:                     YES (ver 53.61.100)
      format:                    YES (ver 53.32.100)
      util:                      YES (ver 51.35.100)
      swscale:                   YES (ver 2.1.100)
      gentoo-style:              YES
    OpenNI:                      YES (ver 1.5.4, build 0)

But I don't know link FFMPEG which I have built it.Can you help me or give me some suggestions? Thanks!
