Encoder-decoder interface question.

Hi!

I thought I ask this here because it's not clear to me

what is in the best interest for tarkin right now/in 
the future. My concern is that right now tarkin 
encoder/decoder is very strongly coupled with the ogg 
file format (IMHO too strongly coupled). I know that 
the Ogg will be Tarkin's first container but I think 
that we should not limit the Tarkin stream only to 
Ogg. An interface layer between the encoder/decoder 
and the file itself would be very needed for many 
reasons:
1. To have an easy way to test the encoding/decoding 
cycle if I try something new (easy in memory "unit 
testing" and not the
pnm->encoder->ogg->decoder->pnm->psnr cycle).
2. Could help others that want to put the stream in 
some other file format. There is no clear way right 
now for this...
3. Easier understanding of the code for the starters. 
I know I had wandered somethimes and get confused is 
this is ogg or tarkin's functionality at what I was 
looking at.
4. If something new comes in the tarkin stream format
then it is no clean way to put those fields in ogg
right now. And a lot of fields are "hard-wired" to
some specific ogg containers. 
5. It's tough to debug that "encoder/ogg coupling"
too.

This was not meant to be a critique to anyone's code 
just wanted to know how to proceed next. I isolated 
the code that does the encoding/decoding and have put 
a small interface around it. It does require some 
cleanup and I had not conected yet to ogg but this 
will come soon.

Am I wasting my time or is there an interest in this 
interface-around-tarkin thing? I know that that there 
is some effort in the "UCI Project" but that wants to 
be much more than a simple encoder/decoder 
interface... Should I try to use "UCI Projects"'s
encoder/decoder interface? (I haven't checked on it
yet to see what it takes...). My interface is very 
thin and because of that I know that some things are 
missing from it,  and I should not invent another 
interface if there is one we should standardize on 
(UCI or something else anyone?).  

I'll gladly accept any critique, comment or idea you 
might have on this! If I'm missing something please 
let me know. Thanks.

Best Regards, 
 Kondoros Attila
