This article shows how you can build your own video community using lighttpd with its mod_flv_streaming module (for streaming .flv videos, the format used by most major video communities such as YouTube) and its mod_secdownload module (for preventing hotlinking of the videos) on Ubuntu 9.10. I will use FlowPlayer as the video player, a free Flash video player with support for lighttpd's mod_flv_streaming module. I will also show how you can encode videos (.mp4 .mov .mpg .3gp .mpeg .wmv .avi) to the FLV format supported by Adobe Flash.
