|

A simple commandline looks like:
|
||||
|
||||
./launch disksrc demo.mp3 | mp3parse | mpg123 | osssink
|
||||
gstreamer-launch disksrc location=music.mp3 ! mad ! osssink
|
||||
|
||||
A more complex pipeline looks like:
|
||||
This plays an mp3 music file music.mp3 using libmad, and:
|
||||
|
||||
./launch disksrc redpill.vob | css-descramble | private_stream_1.0| \
|
||||
(ac3parse | ac3dec | audioink-oss) video_0| (mpeg2dec | videosink)
|
||||
gstreamer-launch disksrc location=music.mp3 ! mp3parse ! mpg123 ! osssink
|
||||
|
||||
Plays and mp3 music file using mpg123
|
||||
|
||||
You can also stream files over http:
|
||||
|
||||
gstreamer-launch httpsrc location=http://domain.com/music.mp3 ! mad ! osssink
|
||||
|
||||
And using gnome-vfs you can do the same with:
|
||||
|
||||
gstreamer-launch gnomevfssrc location=music.mp3 ! mad ! osssink
|
||||
gstreamer-launch gnomevfssrc location=http://domain.com/music.mp3 ! mad ! osssink
|
||||
|
||||
And too play the same song with gnome-vfs via smb:
|
||||
|
||||
gstreamer-launch gnomevfssrc location=smb://computer/music.mp3 ! mad ! osssink
|
||||
|
||||
Here we convert a Mp3 file into an Ogg Vorbis file:
|
||||
|
||||
gstreamer-launch disksrc location=music.mp3 ! mad ! vorbisenc ! disksink location=music.ogg
|
||||
|
||||
And then we can play that file with:
|
||||
|
||||
gstreamer-launch disksrc location=music.ogg ! vorbisdec ! osssink
|
||||
|
||||
Some other useful pipelines are..
|
||||
Plays wav files (currently there are no wav encoders):
|
||||
|
||||
gstreamer-launch disksrc location=music.wav ! parsewav ! osssink
|
||||
|
||||
Converts wav files into mp3 and ogg files:
|
||||
|
||||
gstreamer-launch disksrc location=music.wav ! parsewav ! vorbisenc ! disksink location=music.ogg
|
||||
gstreamer-launch disksrc location=music.wav ! parsewav ! mpegaudio ! disksink location=music.mp3
|
||||
|
||||
You can also use lame for mp3 encoding if you have it installed, it does a
|
||||
much better job than mpegaudio.
|
||||
|
||||
Rips all songs from cd and saves them into a mp3 file:
|
||||
|
||||
gstreamer-launch cdparanoia ! mpegaudio ! disksink location=cd.mp3
|
||||
|
||||
You can toy around with gstreamer-inspect to discover the settings for
|
||||
cdparanoia to rip individual tracks
|
||||
|
||||
Record sound from your sound input and encode it into an ogg file:
|
||||
|
||||
gstreamer-launch osssrc ! vorbisenc ! disksink location=input.ogg
|
||||
|
||||
gstreamer-launch not only handles audio but video as well:
|
||||
For mpeg1 files (video and audio streams respectively):
|
||||
|
||||
gstreamer-launch disksrc location=video.mpg ! mpeg1parse video_00! queue ! { mp1videoparse ! mpeg_play ! sdlvideosink }
|
||||
gstreamer-launch disksrc location=video.mpg ! mpeg1parse audio_00! queue ! { mad ! osssink }
|
||||
|
||||
For mpeg2 files (video and audio streams respectively):
|
||||
|
||||
gstreamer-launch disksrc location=video.mpeg ! mpeg2parse video_0! queue ! { mpeg2dec ! sdlvideosink }
|
||||
gstreamer-launch disksrc location=video.mpeg ! mpeg2parse private_stream_1.0! queue ! { ac3dec ! osssink }
|
||||
|
||||
Note: The types of audio streams in the mpeg files can vary!
