want to write comments
Hi,
I am a littlt new developper, I learn Python and C.
I was looking for some command line program similar to vorbiscomment.
I did not find.
I would just try to write a very simple one in C or Python.
That would be a simple parse of the first bits of the file, if my
guesses are right. But where could I see the amout of binary bit I
should open, and how is the signification of any fields I would

FPGA implementation in the camera
I'm considering implementing the Theora format in the FPGA of the new
camera. The previous model (Elphel 313 - http://www.elphel.com,
https://sourceforge.net/projects/elphel) had smaller FPGA and was
able to produce just motion JPEG utilizing 97% of the resources. The
new (model 333) camera uses 3 times bigger FPGA (and also faster), it
also has increased frame buffer and system memory.

a question about Bitstream Header.
...I have done to implement
that function and confirmed it works well.
So, my question is 'is it really OK to ignore its formal specification?'.
I have heard 'Theora I pecification' has been frozen and I hope
that specification has not been updated yet.

FPGA implementation
Andrey Fillipov posted the following update at his sourceforge website on
11/16/04.
"Coded and simulated the DC predictor module - hope the Theora description I
used matches the actual codec :-)
Also modified the modules released earlier to support non-coded blocks. For
the DCT/IDCT I tried to reduce the power consuption by minimizing switching
of the registers and counters when the

aspect ratio ?
Can someone enlighten me on what the status is of aspect ratio in theora
is ?
The ti structure has aspect_num and _den values, which I assume give the
intended display aspect ratio (e.g. 4/3).
The sample files on the bittorrent seem to say both values are 0 for all
files. I'd think it should at least be made impossible to have a 0 as
the denominator.
The library doesn't check the

16 bits, cast on idct function
Hi all,
Just a stupid question
The IDctSlow function on file idct.c has this line :
ip[0] = (ogg_int16_t)((_Gd + _Cd ) >> 0);
The ip[0] , _Gd and _Cd are of type ogg_int32_t
My question is:
The result of (_Gd + _Cd) can be a number with more than 16 bits ?
(yes, it can be because they are int32, but the algorithm could
guarantee something about that... I dont know...)
If
