$ cd ~/omxplayer
$ make
$ make dist
To install omxplayer system-wide, go into the omxplayer-dist directory and copy the
file tree into the top-level usr/ directory as root:
$ cd omxplayer-dist
$ sudo cp -a usr/* /usr/
There is one last thing you will need to do to use omxplayer . Because omxplayer ac-
cesses the videocore directly on the Raspberry Pi, it uses /dev/vchiq . This device node
is not normally accessible by non-root users, so if you want to be able to run omxplayer
as another user, you'll need to set up a udev rule to allow users in the video group to
access /dev/vchiq :
$ sudo su -
$ echo 'SUBSYSTEM=="vchiq",GROUP="video",MODE="0660"' > /etc/udev/rules.d/
10-vchiq-permissions.rules
$ usermod -aGvideo <USERNAME>
Substitute your username (the default user for Raspbian is pi ) for <USERNAME> in the
usermod command. Then reboot the Raspberry Pi one last time.
You are ready to watch videos with omxplayer now. To watch a video, simply run:
$ omxplayer -o hdmi myvideo.mp4
The -o flag allows you to select the output device. You are probably connected to the
HDMI cable for audio and video. If so, you need to specify hdmi as the output device.
There's no man page for omxplayer, but the options are somewhat documented in the
output of omxplayer --help .
To control the video during playback, use control keys. Table 5-1 shows the more com-
mon control keys for omxplayer .
