One often requested feature that hasnt been incorporated yet is the fullscreen option, Partly because I need some additional time to work on that specific ability, partly because I'm not sure if its that usefull. Playing FLVs fullscreen is very CPU intensive. I think the zoom 2x feature and the resizeable window will suffice for now, but if youd really like a fullscreen option, drop me line in the comments.
An important note to keep in mind: FLV Player uses the Macromedia Flash 8 FLV Playback component to play .flv files with. This component functions best when your .flv contains valid metadata. All .flv files created with recent encoders such as Macromedia Flash 8 Video Encoder have their metadata injected automatically. However, if you wish to view older .flv files they may not contain up-to-date metadata. I highly recommend you use Buraks FLV Metadata Injector to automatically inject correct metadata into those files.This program is the fruit of my spare time. This means there may be some glitches, rough edges and other minor and/or major annoyances you may discover. Please tell me about issues you encounter, so I can fix them and please understand that my time and attention isnt dedicated 100% to maintaining and supporting this free, open source project. Feel free to download the source files and improve upon them.
