Using GStreamer / Writing an Application (if necessary)

[Ian Davidson]

I have been reading the Manual and I think that GStreamer will allow me 
to do what I want to do - but I'm not sure how just yet.

What I want to do is to record - sometimes Audio, sometimes Audio and 
Video - and write out a suitable file - WAV or MP3 if it is Audio, AVI 
or MPEG perhaps if Video.

It would appear from the documentation that I could achieve what I want 
to do by either using gst-launch with a suitable parameter string or by 
writing an application which would do the job.  Either way, I would 
construct a pipeline linking the required elements together and I 
suspect that there would be very little difference between the two as 
far as efficiency is concerned.

So far, though, I have not seen very many elements described.  The 
manual shows, for example purposes, picking up an audio file from disk 
and sending it to the Sound Card - but how do I find which element I 
should use to pick up incoming sound from the Sound Card (or some other 
interface to the Sound Card) and then write it to a file?  Is there a 
'Catalog' of elements?
