Thanks for that link russiansexpat
That looks pretty neat, but what I suspected, it can't be installed on XP (if you're running NTFS) because it uses UMSDOS to mount a FAT32 partition.
I was about to download it, but because I use NTFS, I won't be able to run it.
Anyway, I already dual-boot in my Noteboot between XP and Knoppix 3.3

I briefly checked windoze mplayer/mencoder man page - your http link http://www2.mplayerhq.hu/MPlayer/rel.../man_page.html
and it looks the same as Lunix man page.
Hi Russian,
I was never very good at "piping" in dos/Win32 also so that's probably why I'm not succeding.
Could you show me an example because I feel like I kind of understand you but I can't see any practical results.
And what do you mean by "script"? Your's bash or our's avisynth
We really would like to use our avs filters instead of mencoder's.
Last but not least could you post an encoding mencoder command for a VOB 16:9 PAL(720x576)
anamorphic source with an expected output of 544x576 MPEG2 SVCD without sound and of course non anamorphic.
I sure would like to know how you crop the original 720x576 to 720x552(without the black bars on top/bottom)
encode the video and put the black bars again on the encoded output stream with mencoder filters.
I always end up with a 544x576 fullscreen image or with a 544x306 widescreen (with black bars) image.
I use "-zoom -xy 544" but that's wrong right? Maybe scale, crop, expand...I can't figure it out...
Regards

Hya Karl,
Care to join us
I believe you understand what Russian friend said so can you try and see if avsisynth works with pipes?
Thanks

I think many of you might be surprised to learn that there already exists a powerful encoder for win32 that uses avisynth and mplayer filters. Install ffvfw and ffdshow, configure ffvfw in vdub and under "Input" select "Enable image processing" then click on "Configure". Quite a few options to play with

Hi Dano.
I see that ffvfw has an experimental MPEG encoding function. Does it based on libavcodec? Maybe this is also some way to alternative encoding. Inserting avs scripts to egz. VD and encoding by ffvfw.
Where i can find some features list of ffvfw, while I find testing is dificult without any man page.
Thx.

PS: "Enable image processing" option is innactive in my case.

http://ffdshow.sourceforge.net/ffvfw.html

To enable image processing you need to have ffdshow installed and you need to tell ffdshow what codecs are supported. However, you are right in that you can use avisynth, ffvfw does decent mpeg-1 and is very configurable, haven't yet figured out how to unlock the matrix tables.

I have tried it before and it does use libavcodec but it is much slower on my machine than mencoder. The quality is about the same as mencoder as well, so if you don't care too much about speed, you can get it a try. I only use fluxsmooth and simpleresize for most of my encodes so denoise3d for mencoder is fine for me.

Hello Dano,

Thanks for the update.
I had played with this several months ago, and it always crashed.
To my surprise, I just downloaded the relevant files, AND NOW IT WORKS
Thanks again. It's play time

Hey
What did I just miss What did I just miss
Is it good? Tell me right away.
Did we come up with some way of using *.avs with mencoder
Come on Karl: share it with me/us
I'll do anything to start using something as good as tmpgenc and as fast as cce/mce.
C ya

You did'nt miss much litle spider Last messages have gone off topic, but while we know that ffvfw is based on libavcodec, it is only mater of test speed, if quality is equal to mencoder as Tuco says.
Unlockin matrix tables may be key thing, to produce Kmpegs (read: better picture quality ). GOPs settings are available, I have no problem to configurate this. I'm start to read ffvfw man form link posted by Dano (THX).
So what do you thik Kwag, it's worth to try this


edit (few minutes later): Unfortunately documentation links are broken

Works like a charm.
BUT the only problem, other that you can't change the matrix, is that there's no way to set MIN and MAX bitrates
So the bitrate fluctuations go down to 0 and above 3,000-4,000Kbps

And it looks so delicious
But the max bitrate can be set in "Two passes - 2nd pass" tab (I might me wrong).
And it is realy possible to go to the 0kbps, even in full static scene (egz. black screen) ?

Edit: I've mention Two passes while I still think that this is beter solution for quality and bitrate distribution (of course not in TMPG, for known reasons).

Thanks

I'm too suffer from lack of man page of ffvfw.

Download ffvfw.
Open youre script in VD(mod, avs, ...).
Select full processng mode in Video menu -> and in the same menu is compression.
Pick ffvwf MPEG-4 codec.
Choose encoder MPEGx or mpeg2enc MPEGx.
I think that the rest you'll figure youre self. This is enought for simple speed and qualitty test.
Have fun. Post youre results

PS: in my opinion speed isn't the hard part of this encoder (depends much on avs script). Results are very impressive, even without notch matrixes, and gops settings. This is giving something to think in sleeples nights But I'm not suffering from insomnia, so my bed is calling me Good night.

Hi guys,
Feeling like a hyper noob here
Well I started VdubMod and opened my avs.
I checked the full processing option and opened the compression window.
I chose ffvfw MPEG-4 codec and pushed the Configure button.
A window titled ffvfw configuration appeared.
But I can't find anything that I can change on this window besides the boxes for input/output colorspace
and some other not so important items. Does anyone know what I am doing wrong
I have both ffvfw and ffdshow installed on my pc.
Cheers

In the left upper corner, just bellow window bar, you should be able to choose type of encoder.
And in the left side of the window is white option list: Generic, Motion estimation, etc...
If only I knew how to import image to post (I'm unable to serve it), I could do a screan shot of the config window.

Then I guess my WinXP has gone nuts because I just can see uncompressed there...
Ok guys, don't u go nowhere 'cause I'll be back in 3-4 hours after a fresh XP Pro reinstall.
Then I'll give it a shot again with ffvfw/ffdshow again.

I've found solution to change custom tables
I'll work on this a litle, so maybe tommorow (or today in few hours), I post results and patch to ffvfw.
I also wrote email to Milan, informing that doc page is down. We see what and when will be answer.


Edit: False alarm I've changed tables to all zeros, and i don't se the diference in quality, so propably this will nit work this way.
If you want to try, go to registry HKCU\software\GNU\ffvfw and there are several DWORD walues named qmatrix_(inter/intra)_custom(0-15).
