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

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

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...

Then my first post still exists. If by stream you mean a single video file, then use the following library: 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 ). 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 ( ) 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!
