omxplayer(1) -- Raspberry Pi command line OMX player

Deprecation Warning

Note: omxplayer has been deprecated since 2020; resources are directed at improving vlc.

This is because omxplayer:

• uses openvg for OSD and subtitles which isn't supported on Pi4.
• uses openmax which has been deprecated for a long time & isn't supported with 64-bit kernels
• does not support software decode
• does not support advanced subtitles
• does not support playback from ISO files.
• does not integrate with the X desktop

Please try using vlc. If there are features of omxplayer that vlc does not handle then try reporting here.

Description

OMXPlayer is a command-line video player for the Raspberry Pi. It can play video directly from the command line and does not require a desktop. OMXPlayer leverages the OpenMAX API to make use of the hardware video decoder in the GPU. Hardware acceleration along with direct command-line use on ARM silicon allows ultra low overhead, low power video playback. OMXPlayer was developed as a testbed for the XBMC Raspberry Pi implementation and is quite handy to use standalone.

DOWNLOADING

git clone https://github.com/popcornmix/omxplayer.git

HELP AND DOCS

omxplayer's built-in help and the man page are all generated from this README.md file during make. You may need to change the Makefile if you modify the structure of README.md!

COMPILING

Run this script which will install build dependency packages, including g++, and update firmware

./prepare-native-raspbian.sh

Build with

make ffmpeg
make -j$(nproc)

Install with

sudo make install

CROSS COMPILING

You need the content of your sdcard somewhere mounted or copied. There might be development headers to install on the running Pi system for the crosscompiling.

Edit Makefile.include and change the settings according your locations.

make ffmpeg
make
make dist

Installing OMXPlayer

You may want to specify a valid font path inside the omxplayer shell script. Copy over omxplayer-dist/* to the Pi /.

KEY CONFIG SYNTAX

A key config file is a series of rules of the form [action]:[key]. Multiple keys can be bound to the same action, and comments are supported by adding a # in front of the line. The list of valid [action]s roughly corresponds to the list of default key bindings above and are:

DECREASE_SPEED
INCREASE_SPEED
REWIND
FAST_FORWARD
SHOW_INFO
PREVIOUS_AUDIO
NEXT_AUDIO
PREVIOUS_CHAPTER
NEXT_CHAPTER
PREVIOUS_SUBTITLE
NEXT_SUBTITLE
TOGGLE_SUBTITLE
DECREASE_SUBTITLE_DELAY
INCREASE_SUBTITLE_DELAY
EXIT
PAUSE
DECREASE_VOLUME
INCREASE_VOLUME
SEEK_BACK_SMALL
SEEK_FORWARD_SMALL
SEEK_BACK_LARGE
SEEK_FORWARD_LARGE
STEP

Valid [key]s include all alpha-numeric characters and most symbols, as well as:

left
right
up
down
esc
hex [keycode]

For example:

EXIT:esc
PAUSE:p
#Note that this next line has a space after the :
PAUSE: 
REWIND:left
SEEK_FORWARD_SMALL:hex 0x4f43
EXIT:q

DBUS CONTROL

omxplayer can be controlled via DBUS. There are three interfaces, all of which present a different set of commands. For examples on working with DBUS take a look at the supplied dbuscontrol.sh file.

Root Interface

The root interface is accessible under the name org.mpris.MediaPlayer2.

Methods

Root interface methods can be accessed through org.mpris.MediaPlayer2.MethodName.

Quit

Stops the currently playing video. This will cause the currently running omxplayer process to terminate.

Raise

No effect.

Properties

Root interface properties can be accessed through org.freedesktop.DBus.Properties.Get and org.freedesktop.DBus.Properties.Set methods with the string "org.mpris.MediaPlayer2" as first argument and the string "PropertyName" as second argument.

CanQuit (ro)

Whether or not the player can quit.

Fullscreen (ro)

Whether or not the player can is fullscreen.

CanSetFullscreen (ro)

Whether or not the player can set fullscreen.

CanRaise (ro)

Whether the display window can be brought to the top of all the window.

HasTrackList (ro)

Whether or not the player has a track list.

Identity (ro)

Name of the player.

SupportedUriSchemes (ro)

Playable URI formats.

SupportedMimeTypes (ro)

Supported mime types. Note: currently not implemented.

Player Interface

The player interface is accessible under the name org.mpris.MediaPlayer2.Player.

Methods

Player interface methods can be accessed through org.mpris.MediaPlayer2.Player.MethodName.

Next

Skip to the next chapter.

Previous

Skip to the previous chapter.

Play

Play the video. If the video is playing, it has no effect, if it is paused it will play from current position.

Pause

Pause the video. If the video is playing, it will be paused, if it is paused it will stay in pause (no effect).

PlayPause

Toggles the play state. If the video is playing, it will be paused, if it is paused it will start playing.

Stop

Stops the video. This has the same effect as Quit (terminates the omxplayer instance).

Seek

Perform a relative seek, i.e. seek plus or minus a certain number of microseconds from the current position in the video.

SetPosition

Seeks to a specific location in the file. This is an absolute seek.

SetAlpha

Set the alpha transparency of the player [0-255].

SetLayer

Seeks the video playback layer.

Mute

Mute the audio stream. If the volume is already muted, this does nothing.

Unmute

Unmute the audio stream. If the stream is already unmuted, this does nothing.

ListSubtitles

Returns a array of all known subtitles. The length of the array is the number of subtitles. Each item in the araay is a string in the following format:

<index>:<language>:<name>:<codec>:<active>

Any of the fields may be blank, except for index. language is the language code, such as eng, chi, swe, etc. name is a description of the subtitle, such as foreign parts or SDH. codec is the name of the codec used by the subtitle, sudh as subrip. active is either the string active or an empty string.

ListAudio

Returns and array of all known audio streams. The length of the array is the number of streams. Each item in the array is a string in the following format:

<index>:<language>:<name>:<codec>:<active>

See ListSubtitles for a description of what each of these fields means. An example of a possible string is:

0:eng:DD 5.1:ac3:active

ListVideo

Returns and array of all known video streams. The length of the array is the number of streams. Each item in the array is a string in the following format:

<index>:<language>:<name>:<codec>:<active>

See ListSubtitles for a description of what each of these fields means. An example of a possible string is:

0:eng:x264:h264:active

SelectSubtitle

Selects the subtitle at a given index.

SelectAudio

Selects the audio stream at a given index.

ShowSubtitles

Turns on subtitles.

HideSubtitles

Turns off subtitles.

GetSource

The current file or stream that is being played.

Action

Execute a "keyboard" command. For available codes, see KeyConfig.h.

Properties

Player interface properties can be accessed through org.freedesktop.DBus.Properties.Get and org.freedesktop.DBus.Properties.Set methods with the string "org.mpris.MediaPlayer2" as first argument and the string "PropertyName" as second argument.

CanPlay (ro)

Whether or not the player can play.

Return type: boolean.

CanPause (ro)

Whether or not the player can pause.

PlaybackStatus (ro)

The current state of the player, either "Paused" or "Playing".

Volume (rw)

When called with an argument it will set the volume and return the current volume. When called without an argument it will simply return the current volume. As defined by the MPRIS specifications, this value should be greater than or equal to 0. 1 is the normal volume. Everything below is quieter than normal, everything above is louder.

Millibels can be converted to/from acceptable values using the following:

volume = pow(10, mB / 2000.0);
mB     = 2000.0 * log10(volume)

OpenUri (w)

Restart and open another URI for playing.

Position (ro)

Returns the current position of the playing media.

MinimumRate (ro)

Returns the minimum playback rate of the video.

MaximumRate (ro)

Returns the maximum playback rate of the video.

Rate (rw)

When called with an argument it will set the playing rate and return the current rate. When called without an argument it will simply return the current rate. Rate of 1.0 is the normal playing rate. A value of 2.0 corresponds to two times faster than normal rate, a value of 0.5 corresponds to two times slower than the normal rate.

Metadata (ro)

Returns track information: URI and length.

Aspect (ro)

Returns the aspect ratio.

VideoStreamCount (ro)

Returns the number of video streams.

ResWidth (ro)

Returns video width

ResHeight (ro)

Returns video width

Duration (ro)

Returns the total length of the playing media.
