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 I worte this one.
nFLVPlayer can also be used to play videos from most large online sources (like YouTube, Google Video, Pornotube, Metacafe, iFilm, Dailymotion,Collegehumor,LiveClip, Myspace,Blastro , Blennus, Blip.tv, Bofunk, Bolt, fliqz, AOL, Break.com, Castpost, CollegeHumor, Current TV, Dachix, Danerd, DailySixer.com, DevilDucky, Double Agent, eVideoShare, FindVideos, Free Video Blog, Grouper, Hiphopdeal, Music.com, MusicVideoCodes.info, MySpace Video Code, Newgrounds, PcPlanets, Pixparty, PlsThx, Putfile, Revver,eefoof,Professional Rockstars and many more. ) providing you get the proper URL's.
You can use mozilla Firefox extensions(now called Add-ons but still linking to "Get Extensions" WTF like Ook. Video Ook,Fast Video Download,Google Video Downloader etc. to get the proper links or download the videos.
This player offers common video player functionality controls. As an addition there is an OSD display, Smoothing function, and most recently accessed files and URL's list.
