Omxplayer is a video player specifically made for the Raspberry Pi's GPU made by Edgar (gimli) Hucek from the XBMC project.
Raspberry Pi forum user spenning made precompiled binaries available on the forum. See here.

You do not need to download an MP4 file to watch it with Omxplayer. If you have the URL of a (H.264) rtmp:// stream, just stream it with:
To stream a (H.264) rtmpt://... URL with Omxplayer, just change the head rtmp:// to rtmpt://.
Black screen after playback
If you get a black screen on your X11 sesktop after Omxplayer is finished, you can use this command to restore your view:
xrefresh -display :0
Or you can use a small Bash script for video playback to do this every time:
#/bin/bash omxplayer "$@" xrefresh -display :0
On Raspbian, xrefresh is part of the x11-xserver-utils package (apt-get install x11-xserver-utils).
No rights to VCHIQ
On bare installations of the default distributions, Omxplayer often has insufficient permissions to access /dev/vchiq. One solution would be to run Omxplayer as root, but a nicer solution is to add a udev rule so that /dev/vchiq is also accessible from other users. To accomplish this, do the following under root:
# echo 'SUBSYSTEM=="vchiq",GROUP="video",MODE="0660"' > /etc/udev/rules.d/10-vchiq-permissions.rules
Now add yourself to the group named 'video':
# usermod -aGvideo USERNAME
Reboot the Raspberry Pi, and you should be able to run Omxplayer without the vchiq-error showing up.
When using HDMI make sure to pass '-o hdmi' to Omxplayer if you want the audio to play through the HDMI cable:
omxplayer -o hdmi videofile.mp4
