Video streaming questions
Using Jamroom
Jamroom converts videos to .flv and .m4v formats and uses and HTML5 player (jPlayer - http://jplayer.org/) to play the file, if a users browser does not support HTML5 players, it reverts to using a flash player, hence the two different formats.
Most mobile devices and computer browsers these days support HTML5 players.
Also, if you set a price on an uploaded video, Jamroom creates a sample of the video so the viewer can't see the entire video without paying for it.
Hope this helps!
