Description

Could the capability be added to easily broadcast a motion jpeg to clients using VideoWriter? Does it make sense to add this to video writer, or it's own class? If added to VideoWriter, additional parameters could be passed for binding IP address and port number.

This feature would make debugging on embedded devices, for example, much easier.

It seems to make sense for Issue #1324 to be completed before this one. I can complete these, but I need to find a couple answers to some questions first.

Is there a class used for networking (across platforms) in the opencv source? Or at least an example? I will dig through and look if I don't get an answer. Thanks.

Thanks.

I have this implemented for windows and unix-like systems. It's single threaded but can serve multiple clients. It only does mjpeg right now which means you can view it from a browser. (Great for embedded device debugging). All you do is open a videowriter but specify a port and the fourcc for mjpeg only. Then write frames as usual. I still have to test the unix part and builds then I will submit a pull request.

Sorry for the long delay. I had the code done a while back but bought a new computer and forgot about that enhancement I had been working on, on the previous computer. I will try to get this committed within the next couple of weeks. If not, I'll post what I have so far for another person to finish.

Another point to this, I have noticed that the popular browsers are bugged on what I implemented (multi-part jpeg). Firefox has a massive memory leak but works, while Chrome and IE require it to be embedded in HTML to work. Either way, I'll try to finish it up.
