hey Neverlift

nice to see you here m8.
Well I guess if there is one here who know me well it's you.
As you know I capture my files to 768X576 and the file size is not the first issu for me. My goal is to make 1movie fit on 2 Cd's so I can preserve the maximum possible quality. But what I can say about size improuvment with this codec is that for the same source and same picture I get about 1 to 1.5mb/m less file size with this codec compared to xvid. (my captures are normaly ment to be arround 10 to max 12 MB/M)

What I found very interesting with this codec was all the options and possibilities it gives you to configure it and also the speed of development of this codec! Seems these guys are really putting time and working hard on it!

Anyway it all seems very promissing and I am ready to bet on it as becoming a successful and popular codec.

There is Only one wish I have and its that codec developers try also to optimize there codecs for direct capture too! Ofcours this is possible and we get very good quality already with the existing codecs. But it seems that encoding(Converting) is what they are all mostly focused on for now.

I don't understand - how are you capturing? Fixed bitrate or fixed quantizer? The fDCT function in libavcodec is less accurate, so file size (and detail) is lower at a given quantizer than XviD. If ffmpeg is smaller with fixed bitrate encoding, something is wrong with rate control.

Michael does put a lot of effort into ffmpeg. The modular nature of supporting multple codecs means most options *have* to be configurable. Sometimes this is a problem.

Anyway it all seems very promissing and I am ready to bet on it as becoming a successful and popular codec.

It already is - it's just taken windows users a while to figure it out

Not really, ffmpeg is designed for capturing as well. There's not much you can do to speed it up, apart from resorting to inferior motion estimation modes like zero vectors.

Wow, a lot of settings to understand in the latest ffvfw.

I was wondering is there any information I can read up on the different Motion Estimation routines and Masking techniques?

Also, is the MPEG-4 Encoder without B-frames and QPel standard MPEG-4? How about with B and Q?

Thanks all for re-introducing this interesting and high quality MPEG-4 codec.

There ain`t much information unless you search google for every bit of optional parameters in ffvfw.
Where do they hang out? Do they provide some explanation to what is happening or we have only the changelog? It`s hard to test something you know nothing about!

sorry mates,

I've tried different days, times, both websites but I can't download it... either site not found or a fabulous websearch

where may I get it??

Just checked my site and guess what... It was found! Sorry, but I don't know what's the problem. Try this one. Does it work?

Assault · 13th January 2003, 21:58

I have the same problem as sillKotscha. I cannot download ffvfv neither by Athos' link nor by NiTroGen's. NiTroGen's new link doesn't work either.

I don't know whether it's important but we are both from Germany. Just a thought.

Hello folks!

I've just started using ffvfw and I must say I have some petty troubles and one BIG problem

. The file I have encoded cannot be loaded into VDub. It says either that video frame are corrupted or crashes.

What should I do?????

Hi,

afair older versions of ffvfw were supposed to be compiled with with mingw/msys but when I try it I get this error in the dll-build part:

make[1]: Leaving directory `/home/nico/ffvfw/src/ffmpeg/libavcodec'
dllwrap --mno-cygwin --target=i386-mingw32 \
-o ffvfw.dll -def ./driverproc.def config.o driverproc.o codec.o 2pass.o config.res.o \

-L/usr/lib/mingw -lcrtdll \
/usr/lib/mingw/dllcrt1.o -lmingw32
make: *** [ffvfw.dll] Error 1

Can anyone help me to solve it, please?

Don`t right click->save target, try left click.

Set fourcc to xvid and when done open it in AVIC, set fourcc
description to xvid and voila, you have an xvid avi!

you're really one of those funny guys : lol :

I gave up trying to download ffvfw... although I even have 3 possibilities now to download, it still won't work...

sam_b · 16th January 2003, 20:10

You want it emailing?

Assault · 16th January 2003, 20:30

@ Koke
I could finally download it a few minutes ago. I don't know why but until now my computer wasn't able to load the pages. The direct link didn't work either until today but it was definately not because I did a right click.

Thanks anyway.

Assault

What version of the sources have you? because with the lastest i think you must modify the makefile. And now i just can't access to the cvs (with wincvs or with ie) is there a sourceforge prob or what?

Koke · 16th January 2003, 23:05

Thanks for laughs but this was partly sincere
advice. Why?
When I have tried to open link in a new window
another page opened, normally having no near relation
to FFvfw so, at first, I`ve thought link is no good one.
But then when I clicked it directly there it was!

I know that you knew, but, on the other hand,
one never knows...

molerus · 17th January 2003, 00:04

Hello

Thx Koke for your reply.
I was changing fourcc to XVID earlier, but I was doing it with Nic's XviD installed. It seems that with Koepi's build everything is OK.

I have now another issue.
I'm using ffvfw build 13-th jan.
There are some masking facilities avaiable, like luma masking, P-block masking etc. I tried to use them with the quality set to 100%.
With or without these maskings there are no differences neither in filesize nor in quality. Do these maskings work? (I checked the Masking checkbox).

By the way - where should I look for the latest builds??

molerus · 17th January 2003, 00:08

Ooooooppssssss

My mistake

It was build 2003-01-11
