AVISynth to FFMPEG

[jdobbs]

Is anyone using Avisynth to feed video into FFMPEG for encoding? If so, could you give me an example command line or method?

Thx.

[jdobbs]

Nobody?

Is there a binary somewhere?

Look up the post of Bonzi on 01-09-'04.

Do you meant of FFMPEG? Look here (http://ffmpeg.sourceforge.net/)

I'm specifically interested in looking at FFMPEG's quality in outputting to MPEG-2.

[Wilbert]

That's an old binary.

Grab CVS source from

cvs -z9 -d:pserver:anonymous@mplayerhq.hu:/cvsroot/ffmpeg co ffmpeg

And then use Mingw32 / MSYS (http://sourceforge.net/project/showfiles.php?group_id=2435) to compile. It is pretty easy.

FFMPEG doesnt use the VFW framework does it? So how would you connect it to avisynth?

No it does not use vfw so ATM there is no way you can input avisynth into ffmpeg. If someone could create support for avisynth that would obviously make ffmpeg much more useable for windows users. Here is the mailing list for ffmpeg http://sourceforge.net/mailarchive/forum.php?forum_id=1506 But, avisynth doesn't need the vfw framework to make it work though does it? I mean the Helix Producer obviously doesn't use vfw framework and avisynth works through directshow I suppose. Maybe we should try out mencoder (which allows use of libavcodec and XviD among other things) first though before taking a lot of effort to try to get avisynth to work in avisynth.

1. ffmpeg moved back to mplayer control. cvs as well iirc.
2. you can always use mencoder (win32 version available), which uses ffmpeg. latest compiled version for win32 is 1.0pre3, from 2003-12-09

Yup, this is where my build came from, no worries I know the one of sf is outdated. But thanks for the reminder again, should save some people some frustration :).

hmm i didn't read anything about FFMPEG, but afaik, you can use Avisynth to create a 'fake' avi ... so if FFMPEG can read avi for encoding (it should no ?) there is no reason it can't work :confused:
it's Avisynth who's handling the vfw stuff no ?

well correct me if i am wrong (and i must be ;) )

May be useful, direct access to avisynth without VFW using avilib from linux (includes source for windows):

just wondering if there has been any development in that area over the past year.

Milan did build a patch so mencoder can decode avisynth files. So maybe thats also the way to get ffmpeg working with avs files!?
If youre interested, Ill look for that patch an post it in here.

I've used avs2yuv to pipe input to ffmpeg(Jan cvs), and it worked fine. I think stdin input was broken for a while.

Don't remember it exactly, but it goes something like:

avs2yuv input.avs - | ffmpeg -f yuv4mpegpipe -i - output.(whatever)

EDIT: I guess -f yuv4mpegpipe has to come before -i -

dont expect to see FFMpeg supporting avs nativly it just wont happen. why ? read the mailing list sometime and see how people get crapped on when just asking about compiling or linking under Windows. a VERY anti-Windows crowd. other patches have been suggested in the past for Windows specific things, they were rejected in no time flat.

so the only way you can expect to use FFMpegs encoding is through other programs using avcodec such as QuEnc or the patched version of Mencoder that incredible mentioned.

...or you can use avs2yuv and pipe it to ffmpeg ;)

Platform specific things should stay out of ffmpeg since it is intended to be cross platform, don't ya think? It wouldn't be hard to make ffmpeg read avs directly, but it would work exactly like avs2yuv already does.

nice thought...total bollocks though. :D
fact is there are already platform specific compiler directives, platform specific codecs support etc etc etc yet the mention of windows and any suggestion that would help with it etc throws SOME of the people on the mailing list in to a frenzy of windows slagging and derision.
i can understand why AVS support would be rejected but other ideas in the past, such as compiler directives, that have been rejected with "GCC for windows doesnt need it and we are not interested in any other compilers windows has", is a different matter.
