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