Not really, seems putteh didn't had that much spare
time those last days ...

Fortunately not ;), on opening the file I parse the
streams (as VDub does for AVI files BTW), and retrieve
all necessary information. And luckily someone had the
good idea to put a flag in the headers to know if the
frame is a key frame or not :)

Hum, not really :(

makefile ? what is that ? ;) (I must admit that I am
not too familiar with makefiles)
Well somehow I managed in compiling the sources (and
remains in C :), but had to change some things).
Presently I am trying to implement a dummy video codec
that just copy input data to output to see how behave
UCI and CPI ...
(well and it is not easy because I am not too familiar
with creating / using libraries)
In its current state I cannot do that much things with
UCI because a lot of things are not yet implemented (I
didn't see any function to ask a codec what parameters
it needs, and the functions to start a session with a
codec seems to let us give only one parameter ?!?)

Well anyway I have to correct some things because UCI
couldn't use all the functions in the "codec" I made
(the first function called worked, but an other didn't
and crashed).

For the moment I cannot give the sources back because
I made a lot of changes and I think foogod would just
kill me ;) (and anyway if this doesn't work there is
no need in bothering him with this piece of crap of
mine ;) )
