If you can get a hold of the movie The World Is Not Enough, you can use
it to see what happens. In the opening scene, it can become very, very
blocky. As in notice-at-once blocky. I tried at a bitrate of 1600 and
it didn't do too well. Meanwhile, DivX can do it at a bitrate as low as
800. Anyway, good luck with solving the problem.
Topic: compiled version with debugging symbols?

Hi,
sorry, if this is a little off-topic, but there is no forum, where it
fits better:
I received a beta-version of AMDs Codeanalyzer which seems to be quite
powerful (detecting pipeline stalls, including etc.)=20
Unfortunately the program/DLL to be anaylized has to be compiled with
debugging symbols and "program database" from MS Visual C/C++.=20
Since I don't have it (I'm a linux guy normally...) can anyone make a
compiled version of the codec with debug-flag and .pdb-file? Then
hopefully I can send back some results.=20
And/or is there any place where I can get a copy of visual C/C++
reeeeeally cheap?=20

Eagle: I've of course done that too.. my standard test procedure is to
watch the movie before I grab frames.. and the watching actually helps
me to take screenshots at the appropriate positions.=20
Now the problem I outlined (getting very blocky sometimes) looks
slightly less worse when using the DS filter (slider to the right) but
it's still clearly visible.

same happened here. When i used the playa (which gives out more
informative error message, thanks guys), it says it can't find
appropriate codec. i'm pretty sure the registry entry somewhere that
reads "vidc.divx" =3D "divx.dll" is correctly identifying media tag =
"divx"
... so what else could be the problem?
let me describe my situation here. i was using a previous divxwindows
decoder before (the one that came out without a directshow filter), but
i used the hacked divx filter for the replacement. when i installed the
new alpha48, i uninstalled the previous version first, made sure the
registry and files are clean. and then in the new package, i found out
that divx_.dll should have been called divx.dll ... installation worked
after fixing the file name.
otherwise ... i can't find any possible solution to the problem.

retried today. i thought there might be some conflict between the old
hacked dxshow filter and the new open filter UUIDs, but honestly i don't
know too much about how to identify the old dxshow other than using it's
old name "divx_c32" ... there might be some unclean stuff left in the
registry. who knows?
god hates all those COM interfaces and UUIDs.
i might need to compile a debug version myself to see if any of the
ax/dll get loaded at all. i really think it shouldn't be the registry
problem. it really shouldn't.

Topic: Understanding iDCT

One thing comes to mind - a lot of processor manufacturers have a
library of useful assembler-optimised routines. Perhaps there already
exists an iDCT in ARM assembler, somewhere. Of course, we'd need
permission to use it.
In fact, any ARM asm would help as a learning tool - a guide to opcodes,
coding style, etc.
It's silly to reinvent the wheel=20

I'm a silly guy,
it was easy :
in encore.dsw, I change :
project -> settings -> C/C++ -> category : code generation=20
-> use run-time library : Debug Multithreaded (instead of Debug
Multithreaded DLL)
Now I built divx.dll, I can try it (but what is the best encoder to use
it ??)

Topic: Don't understand thing about performance. Need realtime.

Tell me one thing - can any of MPEG4 encoders work in the realtime?
I looked through the given source and found that a lot of the "critical
time" sections are written on C - doesn't too fast I think.=20
I need 50-100 fps performance (384*288, color) in realtime - i.e. to
write live video.=20
I don't think OpenDivX or some of MPEG4 codecs have such possibilities.=20
So... I need one answer - can it? )

i found a program that pays u to be online , and if u refer friends it
pays too.There are lots of programs like that , but this is the best ,
pays highest and is easy and reliable
I was just trying to learn about divx in mirc when a friend told me
that:Man u can't believe , i found a great program that pays u when u
are online...
I couldn't believe him in that time , but now when i receive my check ,
i really want to thank him.
The best program, easy , reliable and pays the highest.U also win money
refering your friends...

It's not because it is written in C that it isn't efficient.
I suppose you think that Assembler code is faster? Not really, only a
very good assembler programmer can do better code than the compiler. And
even with very good skills, assembler code isn't always more efficient.
And since OpenDivx is in developpement, it isn't the time to put
assembler modules that will more complicate the code than optimize it...
Next, don't expect realtime in a MPEG4 codec, unless you've got a 10Ghz
bazillum... But, maybe in 2-3 years...
Computer power double each 18 months, that's Moore's Law!!!=20

Subject: [OpenDivX] Compliance
Hi,
I'm working (in fact playing ;-) on my side to understand how the
MPEG4 compression is working ... So I've read some papers about it,
for exemple a small part of the MPEG4 ISO paper, and finally I did
compile the microsoft mpeg4 encoder and decoder "fdis" version (V1)
that is used to be the reference codec as the momusys one is. After
that I did generate some movie with this codec and wanted to make
comparaison with the actual opendivx encoder ... but I wonder about
the fact that there is no compatibility between both encoder /
decoder ... For instance : a file compressed with the fdis encoder
won't work with the opendivx decoder and vise-versa ...
What the hell ??? Shouldn't the opendivx be MPEG4 V1 compliant ?
Best regards
- Eric Felten -
