Original commit message from CVS:

first try at hunting old elements that where renamed like :
- parsewav (never existed, should be wavparse)
- vorbisfile (now oggdemux ! vorbisdec)
- disksink (now filesink)

We can also choose to use another type of sink instead of the audiosink.
We could use a disksink to write the raw samples to a file, for example.
We could use a filesink to write the raw samples to a file, for example.
It should also be clear that inserting filters, like a stereo effect,
into the pipeline is not that hard to do. The most important thing is
that you can reuse already existing elements.

Here we convert a Mp3 file into an Ogg Vorbis file:
gst-launch filesrc location=music.mp3 ! mad ! vorbisenc ! disksink location=music.ogg
gst-launch filesrc location=music.mp3 ! mad ! vorbisenc ! filesink location=music.ogg
And then we can play that file with:
gst-launch filesrc location=music.ogg ! vorbisdec ! osssink
gst-launch filesrc location=music.ogg ! oggdemux ! vorbisdec ! osssink
Some other useful pipelines are..
Plays wav files (currently there are no wav encoders):
gst-launch filesrc location=music.wav ! parsewav ! osssink
gst-launch filesrc location=music.wav ! wavparse ! osssink
Converts wav files into mp3 and ogg files:
gst-launch filesrc location=music.wav ! parsewav ! vorbisenc ! disksink location=music.ogg
gst-launch filesrc location=music.wav ! parsewav ! mpegaudio ! disksink location=music.mp3
gst-launch filesrc location=music.wav ! wavparse ! vorbisenc ! filesink location=music.ogg
gst-launch filesrc location=music.wav ! wavparse ! mpegaudio ! filesink 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:
gst-launch cdparanoia ! mpegaudio ! disksink location=cd.mp3
gst-launch cdparanoia ! mpegaudio ! filesink location=cd.mp3
You can toy around with gst-inspect to discover the settings for
cdparanoia to rip individual tracks
Record sound from your sound input and encode it into an ogg file:
gst-launch osssrc ! vorbisenc ! disksink location=input.ogg
gst-launch osssrc ! vorbisenc ! filesink location=input.ogg
gst-launch not only handles audio but video as well:
For mpeg1 files (video and audio streams respectively):
