Using ffvfw to create AviSynth AVI files

[philtre]

So, can anyone tell me, what the procedure is now for loading these fake avis in Vegas?
Which version of AviSynth is required, and so on...

thanks

[Wilbert]

It doesn't matter which version you use. You probably need v2.5x. (I assume you know where to get ffvfw/makeAVIS.)

[philtre]

never mind,
i got it working, apparently, i didn't have avisynth 2.52 installed.
so, i made an avi with forced RGB24 and it works like a charm

thanks

I would like to continue to lobby for an additional option that allows raw audio to be combined with the signpost, instead of actually serving the audio with the video. It would aid and add compatibility between MakeAvis and more applications.

The ability to add the raw audio to the signpost is one of the reasons VFAPI is so compatible with everything. Satish also added this feature to his debugmode frameserver for NLE's for the same reason and it solved a lot of compatibility problems.

Granted, adding the raw audio to the signpost makes the fakeavi much bigger, but I don't see that as an issue now that HD's are so much bigger. Milan, Shodan, I hope you would consider adding this optional feature. I'm hesitant to say it is easy to do because of being a non programmer, but I think I remember Satish mentioned it was a rather trivial thing to do. IIRC, I think it took him less than an hour to add the code and test.

It has been implemented - I have however been unable to find a binary or compile a release build (getting two stupid linker errors). So a little more patience is probably needed.

[sh0dan]

I finally got it to compile! You can download it from the CVS binary page. Both ffvfw "light" and full version available.

Great news and a big thank you. The combination of this new audio wrap and the new DirectShowSource functionality becomes very powerful. For instance I just served a realfile.ram into Vegas via a directshowshource AVS wrapped with MakeAvis. Adding the raw audio as part of the signpost should allow nearly any program to use the fake.avi now. If anybody finds one that cannot load it please post what it was.

I also tested it by loading a 13 gig DV_Type2_Avi file in VDub, created a VDR signpost via the frameserving output of VDub, then used MakeAvis to load an AVS script using AviSource to open the VDR. Makeavis successfully created the signpost with approx 700k of audio.

sh0dan, really great!

Now I am hoping to figure out how to open a tmpg TPR. Will post if/when

/add:
Syntax for loading a TMPG TPR file in avisynth.

LoadVFAPIplugin("drive:\tmpgpath\TMPGEnc.vfp","TMPGsource")
TMPGsource("drive:\your saved tmpg TPR.tpr").converttoyuy2().flipvertical()

[sh0dan]

Great to hear it works.

I open TPR-files in AviSynth using the vfapi converter.

@sh0dan,

I just use MakeAVIS to convert the .avs into fake avi,
the .avs is created from GKnot (I open it with Media Player and it's
working well)... but the .avi result is always flip when I try to play it use the Media Player.

Any idea ?

PS. ffvfw build 13-11-2003.

Thank you.

[DDogg]

Many times it will be flipped in WMP, but should encode correctly. If you want to see it in WMP then you could add a converttoyuy2() statement to the end of your script. If, for an odd situation where that did not work, then use flipvertical() instead.

As said, test a short encode first without using flipvertical(). The encode should be ok. WMP is just real strange on a lot of things and people finally banged me over the head so much that I started using VDub to view before reporting.

Hi,

I´m trying to use MakeAVIS with SoundForge, but it has a little problem. There is no audio!
When I try to open in SoundForge it shows:
Video Length: 00:32:01,686
Audio Length: 00:00:00,067

In Media Player plays perfect!
Only for test, I tried to open the same .avs in Premiere 6.5 and export to PluginPac and open in SoundForge. It works!
I installed version ffvfwAVIS-20031113

Any suggestion?

Thanks,

Alexandre

[sh0dan]

Try selecting "Store uncompressed audio".

[ADLANCAS]

Thanks, it works!:thanks:

Is there a reason why Pluginpac works without storing a uncompressed audio (could MakeAVIS be changed to work in the same way) ?

Hi, I have been using makeavis a little bit now, and though I had much difficulty at first, I finally got it figured out, and I must say it works great. But I have a few suggestions for it that I wonder if could be implemented.
It requires the paths in avs files to be absolute. Is there any way that it could be fixed to accept relative paths as well?
Next suggestion, could it be adjusted to allow batch converting of files? So that you could select like 10 or 20 or however many files at a time, set the same settings for them, and have it output them as avis. This would be really helpfull if you have a lot of files.

[Zarxrax]

Hmmm, I believe I might have found a bug or something. It's really weird though. I installed the "ffvfw AVIS" package off this page: http://cultact-server.novi.dk/kpo/avisynth/avs_cvs.html
It ran fine for a couple of weeks, then suddenly one day Adobe After Effects started crashing when I tryed to run it. Checking the crash info, it said that the problem was with ffvfw.dll. This really perplexed me, as I had been using it for a while with no problems, but I uninstalled ffvfw and then reinstalled it. After Effects started up just fine. Now its been a couple more weeks, and today I went to start up After Effects and once again it crashes, complaining about ffvfw.dll. What could be causing them to not get along together? And moreover, what is causing the problem to just pop up out of nowhere?

@Sh0dan

Would it be reasonable enough to ask for a command-line version of MakeAVIS ?

The Windows ports of Mencoder and FFMPEG are getting much more attention now as alternative MPEG-2 encoders and the fake-AVIs produced by makeAVIS are their only way to open AVS files.

It would help automating the process :)

Thanks in advance.

Cheers,

I can't make it work..
Using avisynth 2.54... The script works fine in vdub, etc.
When I try to make an AVI with MakeAVIS (from latest ffdshow+ffvfw by Athos), it creates useless files... I can't open it in ANY program. And by looking it, it doesn't even have an AVI's Header.

Even a simple version() command won't work... (so it is not an absolute path problem).

Any clues as to why this happens?

[ernstblaauw]

If I want to open a fake AVI (made by MakeAVIS of the ffdshow build 20050312) with DVD2SVCD, the previewing windows sais:
'Could not decompress frame 0'. Is a solution available for this problem?

[Inc]

Thats exactly the Problem I got since the newer builds of 2004/2005.
I think that bug came up when ffdshow/ffvfw became "as one".
So no AVIS-source decoding in CCE (vfw) or Vdub (vfw) was possible.

I never had Problems decoding AVIS files using the old separate installation of the ffvw.dll decoding engine. Thats why all my commandline mencoder encodings in my cases do still use the ffvfw.dll for decoding.

That problem was mentioned by me in the ffdshow mega thread but it seems that it has not been fixed since that time .. so we have to hope/wait ;)

I asked some question about MakeAVIS in the 'ffdshow #2' and 'ffvfw' thread, both located in the new codecs forum. I think it is also interessting for you.
