Videos are automatically converted into FLV and MP4 format when they are uploaded to YouTube. After that you need a Flash enabled web browser to view them. Mobile browsers are getting high on tech but most of them doesn’t support Flash videos. So currently it is impossible to watch YouTube FLV videos live on a web browser. However, there are some applications that let you watch YouTube videos right from their interface without the need of Flash player or any other plugin.

Original Youtube mobile client Google.
Original Youtube player uses the default media player on a mobile phone(Real player) to play Youtube videos. The application encodes the FLV video to steaming formats that can be played with Real Player.

A majority of mobile devices is still not supported with this player.
