there are lot of players for playing videos..
but, for playing video/audio files on internet, you have some defined players, such as media player, flash player etc.,
here media player is one which plays files, but most preferable player for online usage is a flash player,
there are lot of vendors who are providing flash players..
and flash player supports(.flv) extension files, which can be converted at the time of download/upload..
for example, the videos which you watch in you tube are in flash format(.flv)..
when you upload any other kind(extension) file, they will be converted to flash, and then they will be streamed as per your requirement..
flash files take less space to occupy, and they will stream a bit faster...
so, mostly now a days for streaming files online, flash players are used...
