To use omxplayer you'll want to make sure your video is encoded with an H.264 codec and is in a file format like .avi, .mov, .mkv, .mp4, or .m4v. If you have a video in a different format or that won't play you convert it into an H.264 video easily with some free tools. For converting a video to H.264 that omxplayer can play I recommend the Handbrake video transcoder tool. This tool is available for free for Windows, Mac, and Linux machines, and has a relatively simple interface

omxplayer /opt/vc/src/hello_pi/hello_video/test.h264
