Abstract

Video communication is rapidly developing and expanding field. The problem is, we found out early into the project, that things get quite complicated as you try to do more. We delved into the mysteries of video communication over web for a specific project ePomocnik (translates to eHelper). There is a lot of possibility but we singled out a few. First of all we present a few basic technologies used -- Java, Flash, and some protocols used for video communication. What is more, we built three basic solutions for video communication. Two of them have a common base -- Red5 streaming server. First is based on the standard Flash applets for video capture and playback, the second is using Java for video capture. The third solution is depending on VLC player as server and client. Going further from that point, we monitored CPU and network bandwidth usage for every solution and we did a short user survey regarding solution quality. What we concluded was quite interesting, even though nobody puts much faith in Flash anymore, Flash and Red5 combination is still a very strong option. By the choice of users and test data it is still the best solution followed by VLC. Problem with VLC is that it needs quite a bit of tinkering, while Flash is "ready to go". The recommendation for anyone not really demanding would be to just stick with Flash for now. If your resources permit it, you should use VLC or FFmpeg with x264 encoder by building your own distribution compiling it from source and customizing it.
