nFLVPlayer plays Flash Video (tm) format also known as .flv. This format provides the best available compression out there through the VP6 codec. At this time this is the best video format for online video playback ... but it lacks support in other means of ussage. A while ago I had to develop an online video system that needed to play video in this format and I found out there was no decent standalone player to try my video's quality/size in various setups ... so we worte this one. nFLVPlayer can also be used to play videos from most large online sources (like GoogleVideo) providing you get the proper URL's.
