Mpeg

Hi all,
       Need a bit of guidance. I am planning to do a small project out
of my own interest and learning. I have choosen to implement an Mpeg
encoder/deocder.

Planning to provide support for both mpeg 2 and 4. 

But i am stuck at one point. The ISO standard specs cost around 140 $
each. And for Mpeg 2 there are some 10 standards. Now i would not be
able to invest so much. I searched the web, but i dont think i would
find some detailed specs like the ISO documents. Any guidelines in
this regard ?

Also, as i mentioned that there are about 10 standards for Mpeg2,which
one i need to concentrate to develop a minimal encoder/decoder.

I have the same questions for Mpeg 4 too..

Can anyone help me...

thanks in advance and regards

at least regarding the audio part, you might be able to find drafts of 
the standard on the web.

I take the opportunity to ask you a
question: how is going with lame?
It's long time no new realeses show up.

Well, few time and few developpers. There is at least one blocking bug 
to solve.

(but we are off-topic here)

pachu,

That is not a small project. It is in fact a very large project for a
single person. Even for the minimal subset of the standard. If you are
looking to
start a smaall(ish) hobby project, I suggest you should rethink the
idea
and choose something more doable. Of course, I don't know your
background
so I could be wrong.

Actually you are right....It is a huge project. we are actually 3 of
us here....but i guess that also would be less...

The basic idea was to learn concepts of DSP, (video and audio
compression)

Can any one suggest some good project so that we can get a good
exposure to DSP concepts, let it not be too simple...we are planning
to do some usefull project. Any suggestions ?
