NAME

audiopreview - play previews of your audio and video files, and also internet media streams.

CONTENTS

SYNOPSIS

audiopreview [OPTIONS] FILES/URIS...

DESCRIPTION

AudioPreview is a command-line tool that can play previews of your audio files as well as video files, and even internet media streams. It will play your whole media library without any problem and can also be used as a regular media player.

AudioPreview is developped in C and needs Glib and Gstreamer libraries.

Note about notation: To be generic, each file or URI will be called a "stream".

FILE TYPES

Note that you may need different plugins to read specific files. For example, to play mp3 files, you need to install gstreamer0.10-plugins-ugly.

We *suggest* you to install these plugins:
gstreamer0.10-plugins-base
gstreamer0.10-plugins-good
gstreamer0.10-plugins-bad
gstreamer0.10-plugins-ugly

OPTIONS

--colors=TYPE Set when to show colors, TYPE can be ’no’ for no color, ’auto’ for colors only when there is a non-dumb TTY attached to Standard Output, ’yes’ for colors all the time even if the Standard Output is not attached to a TTY. Default: auto.
--debug | -D Show debug information in output (should ONLY be used for bug reporting, for developers or for testing purposes).
--duration=SECONDS | -d SECONDS Change the preview duration for every stream to SECONDS seconds. If DURATION is negative ( < 0 ) it will play each stream till it reaches the END OF FILE (Infinite streams will play indefinitely! ex: live streams or internet radio station, ...). The default is 10.
--entirely | -e Play each given stream entirely starting from the beginning. *Infinite streams will play indefinitely!* This option totally overrides any given -p or -d options.
--fast-seek Change seeking mode to be faster (but less accurate). This will seek to the nearest keyframe instead of the exact time (This might pose problems if --position is 2).
--file=FILE | -f FILE Add every line of FILE to the playlist. FILE should contain new-line-separated URIs or paths. This is done after command-line arguments (if any) are parsed and added to the playlist.
--help | -? Print the usage help.
--loop | -l Activate Loop mode so that when the last stream has been played, we start playing again from the first stream of the list.
--max-duration=SECONDS | -m SECONDS Sets the maximum preview duration to SECONDS (integer). This can be used with the --entirely option and you have streams that can be infinite (like radio stations). (To use with --entirely)
--no-audio Deactivate/disable the audio output.
--no-video Deactivate/disable the video output. You should use this option if you don’t have any DISPLAY running otherwise audiopreview might raise an error if you try to preview video streams.
--position=POSITION | -p POSITION Define the starting position from where to start previewing the stream. POSITION can have these values: 0 (Start), 1 (Middle), 2 (End), 3 (Anywhere). Note that this option is ignored if the stream is not seekable (e.g. internet radio streams, live streams, ...). Default is 3 (Anywhere).
--quiet | -q Quiet or silent output (almost no output execept error and warning messages).
--shuffle | -S Shuffle the playlist before playing the first stream.
--verbose | -v Verbose output.
--version Display the version number.
--volume=PERCENTAGE | -V PERCENTAGE Change the output volume. PERCENTAGE is an integer from 0 to 200. Default is 100 (e.g. audiopreview --volume=100).

SHORTCUT KEYS

When audiopreview is running you can do some specific actions using keyboard keys:

SPACEBAR Pause (or resume) playing.
N Play next stream.
P Play previous stream.
Q Stop playing and exit.
R Restart current stream (it respects the --position argument, for example: if --position is random, which is the default value, then a new random position will be calculated and the stream will be played from this new position). Ignored if stream is continuous (like radio stations).

EXAMPLES

Here are a few examples of common usage:

- Preview 5 seconds of every Ogg file (shuffled) in the current directory:

audiopreview -S -d 5 *.ogg

- Preview 1 minute of a few internet streams:

audiopreview -d 60 http://radio1:port/ http://streamZ/playlist.asp http://streaming:port/

- Play continuously and quietly (volume: 40%) an internet radio station:

audiopreview -V 40 -e http://coolradio:9999/

- Preview 20 seconds in the middle of each mp3 file of a directory:

audiopreview -d 20 -p 1 /dir/to/my/music/*.mp3

- Preview 5 seconds from the start of each AVI video file in a directory, with audio output disabled:

audiopreview --no-audio -d 5 -p 0 /dir/to/my/videos/*.avi

- Play entirely each mp3 file found in ~/Music/ (and in subdirectories):

audiopreview -e -f <(find ~/Music/ -name ’*.mp3’)

- Play (entirely) and loop through all of the ogg files in the current directory:

audiopreview -e -l *.ogg
